There you go! Also, CloudKit provides a specific record type for large binary objects. Careful error handling is absolutely essential for a CloudKit client. If you prefer to read the matrix as code, there's a new boolean-- allowsCloudEncryption--, that you can use to configure this property, That means we can't change our mind later. Next, we'll take a deep dive into the mechanics of sharing. Book about a good dark lord, think "not Sauron", How to choose voltage value of capacitors, Rename .gz files according to names in separate txt-file. If I tap on it, I can see that the Edit button is disabled and the participants entry for Mary shows that she is a Read-Only participant on the share. NSPersistentCloudKitContainer automatically syncs. However, you can get more functionality if you use a custom zone, most notably, support for fetching incremental record changes. I've configured it to be an optional Transformable attribute and checked this new Allows Cloud Encryption checkbox. It may be tempting to think that the above is a completely robust data sharing solution, but its not quite that simple. In the projects settings, set the signing team to your paid developer account. This controller invites other users to contribute to the data in the app. to NSPersistentCloudKitContainer to support sharing. On Mary's device, I'll open Mail and tap the link inside the email I sent, which opens up my application. directly to NSPersistentCloudKitContainer. To make it easy to build applications that use this shared data, NSPersistentCloudKitContainer has to also help us make sense of all of these objects so that we can build informative user interfaces for our users. The CKFetchRecordsOperation operates on one or more records at a time. First, add the following property to DestinationDetailView: Second, you need to add a sheet modifier to the List to present CloudSharingView. And finally, I had to build new user interface elements to display information about the participants on an individual share. To do this, you make a copy of your privateStoreDescription and update its URL to sharedStoreURL. Once youre in this section, you need to specify the container you want to see. Get the most out of CloudKit Sharing Discover how apps can use CloudKit to share records with others. Here you created a CKContainer property using your persistent container store description. One user shows up as a Owner and the other as a Private User, with both users having Read-Write permissions. that I've added to bring up the sharing controller. For example, this user may have a private zone. Also, a CloudKit record may only be shared if it is stored in a private database and is a member of a record zone other than the default zone. Finally, observe that you can use a UserDefaults cached value to avoid unnecessarily saving the subscription more than once. CloudKit notifications arrive via the standard iOS notification mechanism. Now that you have the method to perform the share, you need to present the CloudSharingView when you tap the Share button. Customizations like this necessarily require more complicated code than if I chose not to support sharing. The final topic I'd like to cover today is support for another new feature in CloudKit: encrypted CKRecord values. For example, if I change this line of code to use an existing share, NSPersistentCloudKitContainer will attempt to assign the provided post object to that share. Please note all the code has explanatory comments at the key points. This doesn't seem to work. However, you dont have any metadata about the share. NSPersistentCloudKitContainer also has to understand, how the concepts of owners and participants apply, Let's imagine I have a collection of people. I can see that the Edit button is disabled, and the participants entry for Mary shows. This practice allows CloudKit to better manage network transfer and server-side storage of these types of items. When the user taps the link that was shared earlier and accepts the invitation, the delegate calls this method and launches the app. When and how was it discovered that Jupiter and Saturn are made out of gas? and the participants entry for Jermaine shows. - Accepting a shared note will now move it to the top level of your notes folder - Fixed a bug where clicking on the month name on macOS shifted the calendar weeks - Improved website titles when pasting a web link in NotePlan - iCloud Drive sync is now hidden as a sync option for new users since Cloudkit provides a better sync experience In the Signing & Capabilities section, add the iCloud capability. If I'm allowed to, I can add records that I own to any of those zones just as they can in the zones that I own. So be sure to use NSPersistentCloudKitContainer's initializeSchema method to ensure that all your fields are present and correctly typed before deploying your schema to production. But in my application, I took a slightly different approach. So we've updated our sample application and the documentation to demonstrate how you can use it in your own applications, including how you can write tests to verify how your application responds to the different states objects can be in when working with CloudKit. Go to the first device you created the share from, because you need to be the Owner to access the Share Options. Photos supports another option for sharing: Photos shared albums create a shared collection of images. If you attempt to select record type as CD_Destination and query records from here, you receive an error stating Field recordName isnt marked queryable. we have built in to NSPersistentCloudKitContainer. Toptal handpicks top iOS developers to suit yourneeds. To achieve this, youll need a state property that controls the presentation of CloudSharingView as a sheet. The actual CKRecordID is a bit more complicated in that it includes the zoneID. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. share(_ managedObjects: to share: completion:) is meant to be invoked in the create-share phase of UICloudSharingController's workflow. What has meta-philosophy to say about the (presumably) philosophical work of non professional philosophers? At the moment, when you launch the app, entries in your journal all look the same. But our applications are usually designed, NSPersistentCloudKitContainer has to also help us make sense, of all of these objects so that we can build. where I needed to know whether or not an object is shared. about the CKShare a specific post resides in. I can send it to my friends as an iMessage or email. Once youve completed these steps, the data in your app then automagically sync with iCloud. To get the most out of this session, check out our previous videos on NSPersistentCloudKitContainer: "Using Core Data With CloudKit" from WWDC19 and "Sync a Core Data store with the CloudKit public database" from WWDC20. In many cases, it can infer where records belong based on the relationship they have to other objects. The SharingProvider has methods for binding directly to specific call sites in my application. to communicate these states and privileges. And exactly how much did I have to change in the sample application? To complete the demo, I had to make two other changes. For SQLite-backed stores, Core Data provided ubiquitous persistent storage. CloudKit app require a few items to be enabled on the Capabilities Pane of the Xcode Target: iCloud (naturally), including the CloudKit checkbox, Push Notifications, and Background Modes (specifically, remote notifications). For the CloudKit functionality, Ive broken things into two classes: A lower level CloudKitNoteDatabase singleton and a higher level CloudKitNote class. In addition, they would see my two zones that I share with them and any other zones they are a participant on in their .shared database. I'm going to start by launching my application on Jermaine's device and tapping this plus(+) sign in the upper-right corner to create a new post. If theres no error, the title of the share is set. For iOS and macOS, Apple provides a robust toolkit, called CloudKit API, which allows developers targeting Apple platforms to solve this synchronization problem. Launching the CI/CD and R Collectives and community editing features for How to share Core Data between multiple users? This allows users to share individual records from their private databases with their contacts . Finally, an object may not always be mutable and individual participants can have different permissions on the same object. Then, select the CloudKit checkbox to enable the feature. Now that youve sent an invitation to your second user, you need to set the app to accept the invitation and add the data into the shared store. share NSPersistentCloudKitContainer between app and extension, Core Data sharing with CloudKit: Unable to Accept Share. Within each CKContainer are multiple instances of CKDatabase. Add a destination. It brings together a huge amount of domain knowledge about how CloudKit works and how to operate on records and objects. At the top of your screen, select the dropdown menu and click the container you created from Xcode earlier. Discover how to create informative experiences around shared data and learn about the CloudKit technologies that support these features in Core Data. Here in Xcode, I've opened our sample application, Syncing a Core Data Store with the Cloud. For example, if you want to extend this app to handle multiple Notes rather than just one, you could do so more readily (and with higher resulting performance) than if youd just used Apples convenience APIs. But these three methods for conditionalizing editing, were introduced alongside our .public database support, You can use these methods in your applications. my application can access data in both stores. For the sake of discussion, let's imagine I want to share this photo with some friends of mine. At its Worldwide Developer Conference (WWDC) 2019, Apple introduced the ability to add CloudKit functionality to your Core-Data-backed apps with just a few steps. This sample app demonstrates how to use Core Data CloudKit to share photos between iCloud users. To help navigate some of this complexity you can extend CKError with a few helper methods. CloudKit Notifications provide the means to find out when records have been updated by another client. I want to send each person an invite to work on this post with me via email. Select recordName from the list and ensure the index type is Queryable. to present information about shared objects. More advanced cases can use SQLite, or the equivalent, as a shadow database for offline redundancy purposes. To understand these challenges a bit more clearly, we need to identify two crucial concepts for sharing. Finally, I invoke UICloudSharingController's completion block with the results provided by NSPersistentCloudKitContainer, which tells it I'm ready to continue the sharing flow. With sharing, NSPersistentCloudKitContainer will also create shared zones for me with a CKShare record that controls who can access these zones that I own. Why was the nose gear of Concorde located so far aft? I did this by modifying the CoreDataStack, adding a new persistent store description-- here just a copy of the one for the .private store with a different URL. I'll give it a simple title-- "Sharing demos are great"-- and tap Done. On this screen, you can provide a caption, description and photo of the destination. Over 300 content creators. When the dialog asks whether you would like to open the invitation, choose Open. No specific cutoff point is specified (a maximum of 1MB total is recommended for each CKRecord), but as a rule of thumb, just about anything that feels like an independent item (an image, a sound, a blob of text) rather than as a database field should probably be stored as a CKAsset. You can test all other CloudKit functionality in the simulator, but you must be logged in to your iCloud account on the simulated device. Find centralized, trusted content and collaborate around the technologies you use most. Then, it sets the persistent store based on the scope. To dig deeper into CloudKit, I strongly recommend taking the time to view the various CloudKit presentations from each of the last few WWDCs and follow along with the examples they provide. and some of the permissions on the shared album. and operate on the objects I share with them. Look at the share options. Notice your shared record now has an icon indicating its shared with other users. Once youve completed that task, set showShareSheet, which presents CloudSharingView, to true. manages objects in two CloudKit databases. Instead of invoking methods on NSPersistentCloudKitContainer. So let's take a look at exactly how NSPersistentCloudKitContainer shares objects. Also, to change the sharing permissions because it doesnt work properly on a simulator. Learn iOS, Swift, Android, Kotlin, Flutter and Dart development and unlock our massive was to tell NSPersistentCloudKitContainer. The first iteration of Core Data in iCloud on iOS worked on top of document storage and employed the same iCloud APIs. I've already modified it to support sharing posts, I'm going to start by launching my application, and tapping this plus(+) sign in the upper-right corner, I'll give it a simple title-- "Sharing demos are great"--. Last, if the current user of that share is the owner, returns. The app can then take advantage of various OS-provided notifications, in particular, CKAccountChangedNotification, to know when a user has signed in or out, and initiate a synchronization step with CloudKit (including proper conflict resolution, of course) to push the local offline changes to the server, and vice versa. Next, add the following code under the // TODO: 2 comment: This code creates NSPersistentContainerCloudKitContainerOptions, using the identifier from your private store description. You do a bit of requisite error checking and then simply fetch the actual data from the CKRecord and store the values in your member fields. And then I'll tap this new Action button that I've added to bring up the sharing controller. Although the user has accepted the share, the application must also accept the share using the CKAcceptSharesOperation class as follows: Once a share has been accepted by both the user and the app, the shared record needs to be fetched and presented to the user. Please enable JavaScript to enjoy the best experience. Here I can see their invitation status and some of the permissions on the shared album. which brings us to the second key concept: and CloudKit structure these shared objects. When the app receives a notification, check that it corresponds to the subscription you created, and if so, pass it down to the CloudKitNoteDatabase singleton. Search for jobs related to Cloudkit share data between users or hire on the world's largest freelancing marketplace with 21m+ jobs. The method checks the persistentStore of the NSManagedObjectID that was passed in to see if its the sharedPersistentStore. The actual implementation for isShared is in the CoreDataStack, which manages the persistent CloudKit container for my application. In all, I added a little over 1200 lines of test code, and I hope these examples make it really easy for you to build tests in your own applications. . Let's imagine I have a collection of people I want to share with. Discover how to create informative experiences around shared data and learn about the CloudKit technologies that support these features in Core Data. A participant is any other iCloud account that is allowed to operate on those objects in some way. Download iOS 13.0+ iPadOS 13.0+ Xcode 13.0+ Mac Catalyst 13.0+ Overview As technology advances, people collaborate with others through cloud-based apps more than ever. It's free to sign up and bid on jobs. And here on the table, I have a small pool of devices with me, each logged in to an iCloud account belonging to Heather, Jermaine, or Mary. For apps that are targeted to Apples user base, however, it provides a deeply powerful mechanism for user authentication and data synchronization. Here I've chosen four friends to share the photo with. into the sharingProvider the MainViewController uses. and the cells that correspond to unshared objects don't. These are all the changes I had to make for my first demo, but my application also needs to effectively communicate what objects are shared, who they're shared with, and what those participants can do. Should I include the MIT licence of a library which I use from a CDN? Youre now ready to present the cloud-sharing view and add people to contribute to your journal. At WWDC 2021, Apple introduced a way for you to share your data with other iCloud users and invite them to contribute to your apps data. Looking for something specific? that constrain how they can act on a particular set of objects. In anticipation of this, split the save function into two steps. This is achieved by a call to the preparationCompletionHandler method that was passed to the completion handler. Last, open HomeView.swift and look for the swipeActions modifier. I simply added a button action to instantiate an instance of UICloudSharingController. Hiring? With NSPersistentCloudKitContainer, applications can operate on shared objects from any Apple device. Add the following modifier to the Button: The edit button is now disabled, unless you have read/write permissions for this data. Notice the role and permission for each user. Open CoreDataStack.swift and add the following code to the extension: To use this new method, open DestinationDetailView.swift. These days, modern mobile application development requires a well thought-out plan for keeping user data in sync across various devices. The SharingProvider protocol makes it easy to test these decision points by injection. CloudKit supports both the concept of public and private databases. Can users edit their own private data in CloudKit. It's a little bit more code up front to write all of these tests and structure the application in a way that facilitates this type of injection, but the resulting confidence and reliability are well worth it. Photos shared albums create a shared collection of images that other users can view and, if desired, contribute to. Saving records is, perhaps, the most complicated operation. In addition to this, you set databaseScope to .shared. This is the default database that data gets written to. I had to decorate the post table cells to indicate which ones are shared. Click Add Basic Index. Checks whether the object is shared. With this code in place, navigate back to DestinationDetailView.swift to present CloudSharingView. Stay active, close your rings, and have a great WWDC 2021. To toggle this Boolean, you need to update the logic inside the share button. 2 Reviews. Add the following code as one of the modifiers for your List: This code uses getShare(_:) and retrieves CKShare. Thus, your AppDelegate should call application.registerForRemoteNotifications in didFinishLaunchingWithOptions and implement didReceiveRemoteNotification. This snippet of code is part of a test case I wrote for the MainViewController to ensure that its table cells correctly indicate if a post is shared. just as they can in the zones that I own. CloudKit - How to share multiple records and retrieve shared records? First, update your container type to NSPersistentCloudKitContainer. with their role, permissions, and acceptance state. Swift, Android, Kotlin, Flutter, Dart, Server-Side Swift, Unity, and more! In addition to sending a share link, the app must also be adapted to accept a share and fetch the record for the shared cloud database. I've already modified it to support sharing posts with different iCloud users. CloudKit provides you ready to use data sharing API that allows you to implement collaborative features of your app without much effort. The first step is to create a method that prepares your shared data. If a match returns, this object is already shared. Manage Settings create shares for objects, and accept sharing invitations. Likewise, I can't swipe to delete this post, and if I put the table view in editing mode by tapping the Edit button, I can't delete this post. Returning to the sample application, I can see the data from the first demo is now displayed with some new user interface decorations to indicate that the post is shared. Select your desired delivery method and send the invitation. Open CoreDataStack.swift. Kodeco requires JavaScript. On Jermaine's device now, I'll accept the new share. To this point, youve created a journal entry and shared it with another user. The version held by the server at the time you submitted the request. At the top right is the edit button, which presents a modal to edit your destinations caption and description. CloudKit has its own CKError class, derived from Error, but you need to be aware of the possibility that other errors are coming through as well. Likewise, you can't choose to unencrypt a field that is already encrypted. So I'll change the share options to mark the share as View Only. We and our partners use cookies to Store and/or access information on a device. if the provided objectID is in sharedObjectIDs. Observe CloudSharingView in the context of updating permissions. Its also worth pointing out something you did not have to worry about: user authentication. It rejects specific requests with enough error context in the response to allow each client to make a local, enlightened decision about how to resolve the conflict. So I'll tap Mail and then enter the information for my friends. Then, I set the BlockBasedProvider as the provider for the view controller, completing the injection. For our purposes, a single view application containing a UITextView with the ViewController as its delegate will suffice. In this article, Ill demonstrate how to use CloudKit to keep a users data in sync between multiple clients. CloudKit provides a full range of error codes, with accompanying information, to allow developers to handle various edge cases and, where necessary, provide detailed explanations to the user about possible issues. Last modified on 10 November 2016, at 04:29, An Introduction to CloudKit Data Storage on iOS 10. a class written specifically for testing, which allows me to trivially inject custom logic. First off, you need to make sure youre starting from a valid CKRecord. Log in to your iCloud account on a real device. After adding a few of these customizations, it became obvious I needed a way to ensure they all work correctly, which brings me to the main reason the SharingProvider exists: testing. You would need a unique identifier for that CKRecord. After a short wait, the post I created on Jermaine's device is now visible on this device. It brings together a huge amount of domain knowledge. The most common options are via email or text message. This new checkbox tells NSPersistentCloudKitContainer that the value for this attribute should be stored in the encryptedValues payload of the resulting CKRecord. and a shared zone that they own in their .private database. In this article, Toptal Software Engineer Paul Young demonstrate how to use CloudKit to keep a users data in sync between multipleclients. You can now write, read, and handle remote notifications of updates to your iCloud-stored application data using the CloudKit API. All of this work required accessing some metadata about the CKShare a specific post resides in. Next, I configure an instance of the BlockBasedShareProvider, a class written specifically for testing, which allows me to trivially inject custom logic into the sharingProvider the MainViewController uses. I'll tap the Action button to bring up the sharing controller, but this time, I want the share to be read-only so that the participants can't edit or modify the contents of the share. Another user will see a different set of zones in their .private and .shared databases, depending on whether or not they are the owner of those zones. acceptShareInvitations(from metadata: into persistentStore: I used this method in the AppDelegeate's application, userDidAcceptCloudKitShare( with metadata:) method, to simply pass the incoming share metadata. And you can see it's a bit more complicated than the simple injection I used in the test. I left off the scaffolding for creating the sample data, but the test crafts a mixed set of managed objects, that it identifies as shared or not shared. The first step does a one-time setup in preparation for writing the record, and the second step passes the assembled record down to the singleton CloudKitNoteDatabase class. And now I can see the new post. Download iOS 15.0+ iPadOS 15.0+ Xcode 13.4+ watchOS 8.0+ Overview More and more people own multiple devices and use them to share digital assets or to collaborate for work. However, as a practical matter, it makes sense to use some sort of change coalescing mechanism, such as a background Timer that fires periodically, to avoid spamming the iCloud servers with too many tiny changes. You now see the shared entry on your second device. It's free to sign up and bid on jobs. Because of this, when the app launches and you sync with iCloud, the data you have in iCloud synchronizes with your device and automatically displays. The solution is in CloudSharingController.swift. Tapping that brings up the set of participants. From here, tap the Share button in the top-right corner. Ask with tag wwdc21-10015, Optimize your use of Core Data and CloudKit, Bring Core Data concurrency to Swift and SwiftUI, There and back again: Data transfer on Apple Watch, Build apps that share data through CloudKit and Core Data. When a record is shared, a share link is sent to the recipient user in the form of a URL. The owner is the iCloud account that actually owns an object. This link can be sent in a variety of ways including text message, email, or even via Facebook or Twitter. Here I've chosen four friends to share the photo with. Once you accept the share on the second device, its now part of your shared zone in iCloud. As I mentioned, the SharingProvider includes, and I encourage you to check out their implementations.

The changes get synced, and the entry with the updated permissions now shows Read-Only. The consent submitted will only be used for data processing originating from this website. Making statements based on opinion; back them up with references or personal experience. Since CloudKit is more like a database API, it's hard to say what the URL would even represent. Change the permission to View only. Users may not be signed in, they may have disabled CloudKit for the app, they may be in airplane modethe list of exceptions goes on. Heather, Jermaine, Percy, and Mary are all test accounts I regularly work with when I'm building sharing features. Syncing a Core Data Store with the Cloud. I added a little over 1200 lines of test code, and I hope these examples make it really easy. For each participant, NSPersistentCloudKitContainer manages objects in two CloudKit databases, the .private and the .shared database. When I tap Next, I can see my new album with the photo I shared. Theres no huge harm in setting it, but Apple recommends making an effort to avoid this since it wastes network and server resources. The brute force approach of requiring an active CloudKit connection when using the app is not at all satisfying from the users perspective, and, in fact, may be grounds for rejection from the Apple App Store. a number of API methods to align with each of these concerns. to instantiate an instance of UICloudSharingController. Prior to the release of iOS 10, the only way to share CloudKit records between users was to store those records in a public database. Under the Schema section, select Indexes. The SharingProvider protocol makes it easy. to add specific logic to my application code. If it is shared, I may need to fetch the CKShare or the participants for that object to display more information in my user interface. NSPersistentCloudKitContainer typically manages a private zone. Finally, this test asks the MainViewController for its table cells, verifying that the ones I've included in the sharedObjectIDs set have the expected prefix and the cells that correspond to unshared objects don't. Using canUpdateRecord(forManagedObjectWith:) and canDeleteRecord(forManagedObjectWith:) on persistentContainer, adjust the view logic so it considers permissions. that allows me to call up an Action sheet. How might we build an experience like this? Owners create and share objects with a set of participants. Figure 48 3, for example, shows a share link loaded into the Mail app ready to be sent: When a user receives a share link and selects it, a dialog will appear providing the option to accept the share and open it in the corresponding app. If you wish, you can download and examine the example Note App Xcode project created for this tutorial. An example of data being processed may be a unique identifier stored in a cookie. In the event of a conflict, CloudKit gives you, in the returned CKError, three full CKRecords to work with: By looking at the modified fields of these records, you can decide which record occurred first, and therefore which data to keep. Streaming is available in most browsers, and in the WWDC app. Two separate iCloud accounts To initiate the sharing process. If I'm allowed to, I can add records that I own. If you have any questions or comments, please join the forum discussion below. The version field is simply an illustration of good practice for upgrade proofing, keeping in mind that a user with multiple devices may not update your app on all of them at the same time, so there is some call for defensiveness.
