At the moment, when you launch the app, entries in your journal all look the same. 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. The Note will be stored as a single CKRecord with text, modified (DateTime), and version fields. The solution is in CloudSharingController.swift. Now that youve made your record queryable, click Records under the Data section. To begin the sharing process, add the following code to your persistentContainer below the // TODO: 1 comment: This code configures the shared database to store records shared with you. 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. In the Signing & Capabilities section, add the iCloud capability. Share Core Data between users with NSPersistentCloudKitContainer Ask Question Asked 3 years, 7 months ago Modified 1 year, 8 months ago Viewed 3k times 16 Apple introduced the NSPersistentCloudKitContainer with iOS 13 which enable us to use CloudKit with Core Data. 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. Each of these is mirrored to a persistent store in my application, one using the .private database scope and the other using the .shared database scope. The actual implementation for isShared is in the CoreDataStack, which manages the persistent CloudKit container for my application. Build and run. 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). Then just create a deplink that includes that unique identifier. Owners create and share objects with a set of participants. If you have any questions or comments, please join the forum discussion below. If a match returns, this object is already shared. Customizations like this necessarily require. Navigate to AppDelegate.swift and youll see SceneDelegate is empty. I get a Error Fetching Record error, even if I copy and paste it in. Jordan's line about intimate parties in The Great Gatsby? To understand these challenges a bit more clearly. to write all of these tests and structure the application. The SharingProvider protocol makes it easy. For example, a user may have made edits on one device while in airplane mode, and then absent-mindedly made different edits on another device before turning airplane mode off on the first device. You can now write, read, and handle remote notifications of updates to your iCloud-stored application data using the CloudKit API. Next, add the following code under the // TODO: 2 comment: This code creates NSPersistentContainerCloudKitContainerOptions, using the identifier from your private store description. Hiring? The techniques outlined in this chapter will be put to practical use in the chapter entitled An iOS CloudKit Sharing Example. The next step is to create the container your data will live in. Syncing a Core Data Store with the Cloud. with their role, permissions, and acceptance state. we need to identify two crucial concepts for sharing. More importantly, you have a foundation for adding more advanced CloudKit functionality. Build apps that share data through CloudKit and Core Data. Last, if the current user of that share is the owner, returns. 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. Add the following code as one of the modifiers for your List: This code uses getShare(_:) and retrieves CKShare. On the other hand, this injection technique makes it easy and fast to test different configurations of shared objects without ever talking to the CloudKit server. Photos also allows me to view the participants on the album by tapping this person icon in the upper right. On Jermaine's device now, I'll accept the new share. This snippet of code is part of a test case I wrote, to ensure that its table cells correctly indicate. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. At the top level is CKContainer, which encapsulates a set of related CloudKit data. The app designer is always in the best position to define rules for these situations, which can include everything from context-aware automatic merging to user-directed resolution instructions. Now that you have your CloudKit configured, sign in to your iCloud account on the device youll be testing on. Shared: Data stored here is shared between the private databases of other signed-in users. Lets look now at a layer built on top of that to manage these operations in the context of a specific Note. Then, open the starter project. It checks databaseScope and determines whether its private or shared. Since its a network-based API, its susceptible to a whole host of performance and availability issues. 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 by the presence of their objectID in this set. Sync user data between multiple apps from the same developer. With sharing, NSPersistentCloudKitContainer will also create shared zones for me with a CKShare record that controls who can access these zones that I own. On Mary's device, I'll open Mail and tap the link inside the email I sent, which opens up my application. Well, let me show you. To delete the destination, swipe left to reveal the delete button. Manage Settings Likewise, I can't swipe to delete this post, and if I put the table view in editing mode. This class is initialized with the root CKRecord instance that is to be shared with other users together with the permission setting. The next step of preparing your shared data is to enable storing your data in iCloud. Swift 5.6 | iOS 15 | Xcode 13 Table of Contents Although iCloud is only available to Apple customers, CloudKit provides an incredibly powerful platform upon which to build really interesting and user-friendly, multi-client applications with a truly minimal server-side investment. . the participants, and their permissions and roles. CloudKit prefixes your entities with CD to distinguish them from traditional CloudKit records. So I'll tap Mail and then enter the information for my friends. I adopted a new method on NSPersistentCloudKitContainer to create the share. Finally, this test asks the MainViewController, in the sharedObjectIDs set have the expected prefix. Pauls been a developer for nearly three decades, working with many tech stacks but with a focus on Apple. 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. share(_ managedObjects: to share: completion:) is a new method designed to pair directly with UICloudSharingController. Once you accept the share on the second device, its now part of your shared zone in iCloud. was to be able to accept share invitations. Thankfully, CloudKit is explicitly designed to handle this condition. But let's take a look at how NSPersistentCloudKitContainer uses Record Zone Sharing to share managed objects. There you go! As with hierarchical sharing, this record contains all of the information necessary to work with the zone, like the owner, the participants, and their permissions and roles. From this screen, you can take a few actions. Sharing with one other person is interesting, Each of these participants will be able to access. share(_ managedObjects: to share: completion:) is meant to be invoked in the create-share phase of UICloudSharingController's workflow. Then, select the CloudKit checkbox to enable the feature. Tapping that brings up the set of participants. and a shared zone that they own in their .private database. informative user interfaces for our users. I can send it to my friends as an iMessage or email. Photos implements a system control here in the lower left that allows me to call up an Action sheet. These options are accessed and modified by tapping the Share Options item at the bottom of the cloud sharing controller view. In a CloudKit database-- for example, the .private database-- NSPersistentCloudKitContainer typically manages a private zone to store the objects an application creates. 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. The way to enable these silent notifications is to set the shouldSendContentAvailable property on the CKNotificationInfo instance, while leaving all of the traditional notification settings (shouldBadge, soundName, and so on) unset. However, Apple strongly urges developers to use the operations rather than the convenience methods. - 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 Participants can have different roles and permissions. Were you able to figure it out? Find centralized, trusted content and collaborate around the technologies you use most. We'll show you how to encourage collaboration between people using your app and support those interactions with Apple frameworks. In my brief demo, I showed an application that makes use of two CloudKit databases, the .private and the .shared database. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. was to tell NSPersistentCloudKitContainer. As you prepare to present your CloudSharingView, you need this property because the second parameter of CloudSharingView is a CKContainer. we think of our objects in terms of NSManagedObject. 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. When a record is shared, a share link is sent to the recipient user in the form of a URL. From here, you store a reference to CKShare that returns from the share method. Stay active, close your rings, and have a great WWDC 2021. Apps can support such use cases by moving user data to CloudKit and implementing a data sharing flow that includes features like share management and access control. This second step may be repeated in the case of a conflict. Second, enable the iCloud capability in your app. before they are uploaded to the CloudKit server. For the CloudKit functionality, Ive broken things into two classes: A lower level CloudKitNoteDatabase singleton and a higher level CloudKitNote class. At the top right is the edit button, which presents a modal to edit your destinations caption and description. Also, CloudKit provides a specific record type for large binary objects. Now that you have the method to perform the share, you need to present the CloudSharingView when you tap the Share button. But how does all of this work? Was Galileo expecting to see so many stars? Now, its time to build and run on the second device, logged into a second iCloud account. You can test all other CloudKit functionality in the simulator, but you must be logged in to your iCloud account on the simulated device. Can users edit their own private data in CloudKit. Then setup deeplinking for your app. In this article, Toptal Software Engineer Paul Young demonstrate how to use CloudKit to keep a users data in sync between multipleclients. Since CloudKit is deeply tied to Apples operating systems and devices, its not suitable for applications that require a broader range of device support, such as Android or Windows clients. Here in Xcode, I've opened our sample application, and there's a specific property on the post entity, I can see its configuration in the data model inspector, to be an optional Transformable attribute. It is important to be aware that when a share recipient accepts a share they are actually receiving a reference to the original record in the owners private database. The convenience API is much more accessible, while the operation approach can be a bit intimidating. Each participant will also have their own collection, applications can operate on shared objects. with the CloudKit server in the container associated. Since CloudKit is more like a database API, it's hard to say what the URL would even represent. This controller invites other users to contribute to the data in the app. In this session, I'll show you how to easily build applications that use NSPersistentCloudKitContainer to share data with multiple iCloud users. It brings together a huge amount of domain knowledge. Theres one minor bug with your app at the moment. NSPersistentCloudKitContainer turns those managed objects. However, you can get more functionality if you use a custom zone, most notably, support for fetching incremental record changes. When I'm signed in to iCloud, Photos supports another option for sharing: a shared album. and the cells that correspond to unshared objects don't. that allows me to call up an Action sheet. 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. of shared objects without ever talking to the CloudKit server. The UICloudSharingController class provides a pre-built view controller which handles much of the work involved in gathering the necessary information to send a share link to another user. Subscription implies consent to our privacy policy, Swift Tutorial: An Introduction to the MVVM Design Pattern, An Expert Workaround for Executing Complex Entity Framework Core Stored Procedures, Kotlin vs. Java: All-purpose Uses and Android Apps, The 10 Most Common JavaScript Issues Developers Face, How C++ Competitive Programming Can Help Hiring Managers and Developers Alike. 2 Reviews. It is important to be aware that this fetch operation must be executed on the shared cloud database instance of the app instead of the recipients private database. Both the CKShare and associated CKRecord object are then saved to the private database. If I tap on it, I can also see the participants, displayed at the bottom of the detail view controller. I can see my new album with the photo I shared. Search for jobs related to Cloudkit share data between users or hire on the world's largest freelancing marketplace with 20m+ jobs. directly to specific call sites in my application. Photos also allows me to view the participants on the album. With a free Kodeco account you can download source code, track your progress, For app developers, the situation was even worse. In Record Zone Sharing, shared CKRecords are contained inside a shared CKRecordZone. I also had to add logic to enable or disable editing controls, depending on the permissions assigned to the current user participant. 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. Apple has been adding data sharing into many of its first-party apps, including: Files Reminders Notes Calendar Photos Activities Find My Maps Music Health This method accepts the share with the CloudKit server in the container associated with the persistent store I provide-- here, the shared store for my application. here, the shared store for my application. Tap the shared object to go to the detail screen. for you to build tests in your own applications. Instead of invoking methods on NSPersistentCloudKitContainer. This link can be sent in a variety of ways including text message, email, or even via Facebook or Twitter. I needed a way to ensure they all work correctly. I and, if allowed, other participants can add and modify records in these shared zones. But this isn't how NSPersistentCloudKitContainer works. Change the permission to View only. At the top level is CKContainer, which encapsulates a set of related CloudKit data. Observe CloudSharingView in the context of updating permissions. 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. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. CloudKit - Share Files between Users via a URL, https://github.com/iRareMedia/iCloudDocumentSync, https://github.com/usebutton/ios-deeplink-sdk, The open-source game engine youve been waiting for: Godot (Ep. catalogue of 50+ books and 4,000+ videos. Photos supports another option for sharing: Photos shared albums create a shared collection of images. Then, I set the BlockBasedProvider as the provider for the view controller, completing the injection. Let's get started with sharing. into the sharingProvider the MainViewController uses. All the user needs to do at this point is enter the contact details for the intended share recipient and send the message. I had to build new user interface elements, to display information about the participants, All of this work required accessing some metadata. Toptal handpicks top iOS developers to suit yourneeds. This doesn't seem to work. Select CD_Destination. Did you figure it out? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. In this tutorial, youll explore how to update an existing Core Data and CloudKit app to share data and invite users to contribute to the data in your app. When the app comes up, youll notice the shared journal entry doesnt show up. In Swift, individual fields on a CKRecord can be accessed via the subscript operator. Participants can have different roles and permissions that constrain how they can act on a particular set of objects, which brings us to the second key concept: how NSPersistentCloudKitContainer and CloudKit structure these shared objects. Finally, I invoke UICloudSharingController's completion block with the results provided by NSPersistentCloudKitContainer, which tells it I'm ready to continue the sharing flow. That means we can't change our mind later and choose to encrypt fields that aren't already encrypted today in production. Every app automatically gets a default CKContainer, and a group of apps can share a custom CKContainer if permission settings allow. This is a thorny problem with many gotchas and pitfalls, but users expect the feature, and expect it to work well. On Apple platforms, there are a number of ways we can share the data our applications create. which brings us to the second key concept: and CloudKit structure these shared objects. Differentiating private data and shared data in SwiftUI. CloudKit organizes data via a hierarchy of classes: CKContainer, CKDatabase, CKRecordZone, and CKRecord. After adding a few of these customizations. Its fair to say iCloud got off to a bit of a rocky start. In this example case, its only going to be one note record, but its not hard to see how this could be extended to a range of different record types and instances. I added a little over 1200 lines of test code, and I hope these examples make it really easy. Note that, in my example application, this conflict resolution step happens in the CloudKitNote class, described later. 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. Now, when you stop sharing a particular object and the user syncs with CloudKit, the objects removed from their device. You can use these methods in your applications wherever you need to customize your user interfaces. that constrain how they can act on a particular set of objects. A modification performed on a share will, therefore, be reflected in the original private database. 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. The SharingProvider protocol makes it easy to test these decision points by injection. This means not only the owner but also the second user can modify the data shared with them. Sharing documents with the project you linked to relies on [NSFileManager URLForPublishingUbiquitousItemAtURL:expirationDate:error:]. Now, encryption with CloudKit is an at-introduction time decision. These silent pushes happen entirely without user visibility or interaction, and as a result, dont require the user to enable push notification for your app, saving you many potential user-experience headaches as an app developer. to combine the .private and .shared databases. Heather, Jermaine, Percy, and Mary are all test accounts. When I tap Next, I can see my new album with the photo I shared. 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. Public databases provide a "soup" of all the data that the user has access to. CloudKit is built on top of Apples iCloud service. When the user taps the link that was shared earlier and accepts the invitation, the delegate calls this method and launches the app. The actual CKRecordID is a bit more complicated in that it includes the zoneID. NSPersistentCloudKitContainer also has to understand, how the concepts of owners and participants apply, Let's imagine I have a collection of people. CloudKit automatically configures every CloudKit-enabled app out of the box to have a public CKDatabase (all users of the app can see everything) and a private CKDatabase (each user sees only their own data). Last, open HomeView.swift and look for the swipeActions modifier. See the solution below: [spoiler title=Solution 1] Fetching a record by name is very straightforward. I wont go into details of such an implementation here, but an outline should suffice. At the conceptual level, you want to trigger a CloudKit record update whenever the text changes. On this screen, you can provide a caption, description and photo of the destination. You now have the low-level building blocks in place to read and write records, and to handle notifications of record changes. Then, it sets the persistent store based on the scope. Launch a simulator. I'll open Mail and tap the link inside the email I sent, And exactly how much did I have to change, Sharing is by far the most complicated feature. Third, create an iCloud container that hosts your data in iCloud. 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. How did StorageTek STC 4305 use backing HDDs? Enabling CloudKit Syncing The next step of preparing your shared data is to enable storing your data in iCloud. persistentContainer calls this method. Finally, one of the most important aspects of any operation is the qualityOfService value. And now I can see the new post. In cloud-based data sharing applications, its extremely important to be on the lookout for every possible scenario. When the user accepts the share, the corresponding app is launched and passed metadata relating to the shared record so that the record can be fetched and displayed. 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. A user of an app could, for example, make one or more records accessible to other users so that they can view and, optionally, modify the record. to present information about shared objects. To edit or update the caption or description, tap the destination cell to see the detail screen. With this code in place, build and run on your second device. Here I used isShared to decide whether or not to convert the title of a post to an attributed string and prefix it with the person.circle symbol to show that the post is part of a share. Clash between mismath's \C and babel with russian. 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. 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. This is a cute trick in Swift that allows me to simply check if the provided objectID is in sharedObjectIDs. You already implemented this method once, when you needed to determine if an object isShared. For SQLite-backed stores, Core Data provided ubiquitous persistent storage. Before an app can take advantage of CloudKit sharing, the CKSharingSupported key needs to be added to the project Info.plist file with a Boolean value of true. 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. Next, add the following code below the // TODO: 3 comment: This code adds your shared NSPersistentStoreDescription to the container. CloudKit supports both the concept of public and private databases. How might we build an experience like this? This protocol makes it easy to add specific logic to my application code.
