This takes you to a screen to add a recent destination you visited. If I tap on it, I can also see the participants displayed at the bottom of the detail view controller with their role, permissions, and acceptance state. Now I'm going to add a new post, give it a title, and tap Done. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. At what point of what we watch as the MCU movies the branching started? I set the BlockBasedProvider as the provider. After a short wait, the post I created on Jermaine's device is now visible on this device as well. I've configured it to be an optional Transformable attribute and checked this new Allows Cloud Encryption checkbox. Accepting share invitations and fetching the shared data. I'm Nick Gillett, an engineer here at Apple on the Core Data team. So let's look at how I've changed my application to communicate these states and privileges. Page - Sharing data between User Controls without access to the Page class - Accessing data between user controls WPF - Passing data between user controls in wpf - Pass data between parent child user controls . 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. Youll need to ensure that you have set a unique bundle identifier at this point. After the share is accepted, NSPersistentCloudKitContainer automatically syncs all of the shared objects into the local store. Then setup deeplinking for your app. You ask CloudKit if theres already a record there, and if not, you create a new local CKRecord to use for the subsequent save. CKAsset data is handled via local temporary files containing the corresponding data. Thankfully, CloudKit is explicitly designed to handle this condition. You could use the recordId for this. Now that you have the method to perform the share, you need to present the CloudSharingView when you tap the Share button. It's called the SharingProvider. In this post, we will talk about zone sharing. If I tap on it, I can also see the participants, displayed at the bottom of the detail view controller. This chapter has covered the basics of CloudKit sharing, a topic which will be covered further in a later chapter entitled An iOS CloudKit Sharing Example. Every app automatically gets a default CKContainer, and a group of apps can share a custom CKContainer if permission settings allow. 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. However, to allow other users to interact with this data, you need to update your NSPersistentCloudKitContainer. Once youve completed that task, set showShareSheet, which presents CloudSharingView, to true. If its not shared, create the share from the destination object. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page..

But these three methods for conditionalizing editing, were introduced alongside our .public database support, You can use these methods in your applications. Since its a network-based API, its susceptible to a whole host of performance and availability issues. Naturally, this domain knowledge is reflected in the APIs we have built for NSPersistentCloudKitContainer. 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. The first change I had to make was to tell NSPersistentCloudKitContainer to mirror the .shared CloudKit database to a new persistent store. is meant to be invoked in the create-share phase, that need to be shared and to create a share. Swift 5.6 | iOS 15 | Xcode 13 Table of Contents provided by NSPersistentCloudKitContainer. When the dialog asks whether you would like to open the invitation, choose Open. Owners create and share objects with a set of participants. Then, select the CloudKit checkbox to enable the feature. 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 learn more, see our tips on writing great answers. Connect and share knowledge within a single location that is structured and easy to search. Subscriptions are one of the most valuable CloudKit features. Basic CloudKit Setup CloudKit organizes data via a hierarchy of classes: CKContainer, CKDatabase, CKRecordZone, and CKRecord. In the window that comes up, enter your containers name. NSPersistentCloudKitContainer automatically syncs. Stay active, close your rings, and have a great WWDC 2021.

Select your desired delivery method and send the invitation. The first is the notion of a set of actors. Launch a simulator. The same note fields for text and modified datetime can be stored locally in a file via NSKeyedArchiver or the like, and the UI can provide near full functionality based on this local copy. New in iOS 15 is acceptShareInvitations(from:into:completion:). that allows me to call up an Action sheet. Last, head to the CloudKit Console so you can verify your data. So I'll tap Mail and then enter the information for my friends. Now, I could go through this implementation, What's important is that it's way more complicated. NSPersistentCloudKitContainer also has to understand, how the concepts of owners and participants apply, Let's imagine I have a collection of people. Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee. As always, I can't wait to see what you build with NSPersistentCloudKitContainer. Then just create a deplink that includes that unique identifier. When a record is shared, a share link is sent to the recipient user in the form of a URL. Finally, I'll tap Send to send the email. 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. The answer is, "Not much." 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. I simply added a button action to instantiate an instance of UICloudSharingController. Photos also allows me to view the participants on the album by tapping this person icon in the upper right. Synchronizing a Local Store to the Cloud. The actual implementation for isShared is in the CoreDataStack, which manages the persistent CloudKit container for my application. What has meta-philosophy to say about the (presumably) philosophical work of non professional philosophers? When the user taps the link that was shared earlier and accepts the invitation, the delegate calls this method and launches the app. 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. So that's how we use NSPersistentCloudKitContainer to combine the .private and .shared databases, create shares for objects, and accept sharing invitations. 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 new payload on CKRecord allows values to be encrypted using key material from the user's keychain. Build and run. 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. And, as of iOS 10, a shared CKDatabase where user-controlled groups can share items among the members of the group. 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. Then, I set the BlockBasedProvider as the provider for the view controller, completing the injection. more complicated code than if I chose not to support sharing. It is also possible to serialize CKRecords directly to and from local storage. The class contains all the necessary methods and properties you need to interact with Core Data. if I change this line of code to use an existing share, NSPersistentCloudKitContainer will attempt to assign. The only way to distinguish the private records versus shared records is to tap the detail and view the role in the participants list. In many cases, it can infer where records belong based on the relationship they have to other objects. Select Private Database. 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.

If you've worked with sharing before, you're probably familiar with hierarchical sharing, where these records are associated with a root record called the share. 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. As you prepare to present your CloudSharingView, you need this property because the second parameter of CloudSharingView is a CKContainer. Now, I could go through this implementation line by line, but that's not what's important here. 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. 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. bookmark, personalise your learner profile and more! 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. To understand these challenges a bit more clearly, we need to identify two crucial concepts for sharing. Careful error handling is absolutely essential for a CloudKit client.

The last change I had to make was to be able to accept share invitations, which I do using this new method on NSPersistentCloudKitContainer: 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 directly to NSPersistentCloudKitContainer. we need to identify two crucial concepts for sharing. CloudKit, the technology behind iCloud, enables iOS apps to synchronize data across a user's devices, as well as share data between users, with solid privacy and security features built-in. I am not going to get very fancy in my example; I am using the modified field to declare that the most recent update wins. Over time, however, Apple has addressed these issues. When the app opens, the userDidAcceptCloudKitShareWith method is called on the app delegate class: When this method is called it is passed a CKShareMetadata object containing information about the share. 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. to add specific logic to my application code. I simply give the new album a title and then tap Next to choose the set of participants. Two separate iCloud accounts To initiate the sharing process.

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. Owners create and share objects with a set of participants. 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. After the share has been saved to the database, the cloud sharing controller needs to be notified that the share is ready to be sent. You could solve this by creating a CKRecord that contains a CKAsset which is the file that you want to share. This is a thorny problem with many gotchas and pitfalls, but users expect the feature and expect it to work well. This is a cute trick in Swift that allows me to simply check if the provided objectID is in sharedObjectIDs. rev2023.3.1.43269. You need to extract information about the participants of this share. Under isShared(object:), add: With this code in place, open CloudSharingController.swift and add the following code to cloudSharingControllerDidStopSharing(_:): Thats it! Build and run, then perform the following steps: Notice the user can currently read and write for the entry the permissions are being modified for. In a CloudKit database-- for example, the .private database-- NSPersistentCloudKitContainer typically manages a private zone to store the objects an application creates. What's important is that it's way more complicated than I can easily exercise every time I want to verify a change to the table view, and trying to do so would add a lot of friction to the development process. For iOS and macOS, Apple provides a robust toolkit, called CloudKit API, which allows developers targeting Apple platforms to solve this synchronization problem. 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. 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. 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. Let's see that in action. From here, tap the Share button in the top-right corner. Discover how to create informative experiences around shared data and learn about the CloudKit technologies that support these features in Core Data. So let's take a look at exactly how NSPersistentCloudKitContainer shares objects. Xcode prefixes the container name with iCloud. to test these decision points by injection. 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. 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. From here, you store a reference to CKShare that returns from the share method. If a match returns, this object is already shared. with the CloudKit server in the container associated. Not the answer you're looking for? With sharing, NSPersistentCloudKitContainer will also create shared zones for me with a CKShare record that controls who can access these zones that I own. This second step may be repeated in the case of a conflict. In Record Zone Sharing, shared CKRecords are contained inside a shared CKRecordZone. Clash between mismath's \C and babel with russian. Does Cast a Spell make you a spellcaster? Ill focus on an iOS application, but the same approach can be used for macOS clients as well. A participant is any other iCloud account. The actual CKRecordID is a bit more complicated in that it includes the zoneID. It might make more sense for CKAsset, but for now Apple hasn't added the capability. 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. 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. An object that represents activity in a persistent CloudKit container. We'll show you how to encourage collaboration between people using your app and support those interactions with Apple frameworks. Change the permission to View only. However, you can get more functionality if you use a custom zone, most notably, support for fetching incremental record changes. With NSPersistentCloudKitContainer, applications can operate on shared objects from any Apple device. Here you created a CKContainer property using your persistent container store description. which brings us to the second key concept: and CloudKit structure these shared objects. Join our team. So I'll change the share options to mark the share as View Only. introduced in the "What's New in CloudKit" session. Although this adds complexity to the client, its ultimately a far better solution than having Apple come up with one of a few server-side mechanisms for conflict resolution. I had to decorate the post table cells to indicate which ones are shared. This view contains the logic for your share button. We call them the owner and the participants. Figure 48 2 shows an example share options settings screen: Once a method of communication has been selected by the user from the cloud sharing controller, the completion handler assigned to the controller will be called. they would see my two zones that I share with them, and any other zones they are a participant on, So how does NSPersistentCloudKitContainer. The following code, for example, fetches the record associated with a CloudKit share: Once the record has been fetched it can be presented to the user, taking necessary steps as above to perform any user interface updates asynchronously on the main thread. Hi. How might I do that? wherever you need to customize your user interfaces. 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. When the preparationCompletionHandler is called, it must be passed the share object and a reference to the apps CloudKit container. [music]. Heather, Jermaine, Percy, and Mary are all test accounts. CloudKit organizes data via a hierarchy of classes: CKContainer, CKDatabase, CKRecordZone, and CKRecord. 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. Note also, I am using a CKQuerySubscription with a very simple always true predicate to watch for changes on the one (and only) Note record. Here I've chosen four friends to share the photo with. Next, add the following code below the // TODO: 3 comment: This code adds your shared NSPersistentStoreDescription to the container. directly to specific call sites in my application.
