As the new requirement for Privacy manifests is coming this Spring 2024 (https://developer.apple.com/news/?id=r1henawx), Apple released a list of SDK's that need to comply with this requirement and provide a privacy manifest file: https://developer.apple.com/support/third-party-SDK-requirements/ I have some questions: Do i need to declare a privacy manifest file for the SDKs if i'm updating an old app that already includes one of these SDKs? Apple states "when you submit an app update that adds one of the listed SDKs as part of the update" which in my understanding applies only when an app adds an SDK for the first time in an app update. What happens with SDK's that are not in this list? Should every single SDK an app uses to include the privacy manifest file?

Hello Apple Community, Issue encountered during the installation of an app via DDM (Declarative Device Management) on iOS 17.3 devices. When applying an app configuration and managed app list status event through declarative management, the configuration is successfully applied, but the configured app is not being installed on the device. Upon closer inspection, we have identified that the error "ManagedAppDistribution.ManagedAppDistributionError" is being logged during this process. My Configuration: { "Type": "com.apple.configuration.app.managed", "Identifier": "com.mdm.1740e623-4361-498d-af02-b433500d58bd.ManagedAppDDM", "ServerToken": "1706282674113", "Payload": { "AppStoreID": "361309726", "InstallBehavior": { "License": { "VPPType": "Device" }, "Install": "Required" } } } { "Type": "com.apple.configuration.management.status-subscriptions", "Identifier": "com.mdm.9c70c80f-406a-425a-8829-1025652f05c6.ManagedAppListStatus", "ServerToken": "1706282673976", "Payload": { "StatusItems": [ { "Name": "app.managed.list" }, { "Name": "mdm.app" }, { ... } ] } } DDM Response: { "StatusItems": { "management": { "declarations": { "activations": [ { "active": true, "identifier": "DEFAULT_ACT_0", "valid": "valid", "server-token": "1706282674113" } ], "configurations": [ { "active": true, "identifier": "DEFAULT_STATUS_CONFIG_0", "valid": "valid", "server-token": "3" }, { "active": true, "identifier": "com.mdm.1740e623-4361-498d-af02-b433500d58bd.ManagedAppDDM", "valid": "valid", "server-token": "1706282674113" }, { "active": true, "identifier": "com.mdm.9c70c80f-406a-425a-8829-1025652f05c6.ManagedAppListStatus", "valid": "valid", "server-token": "1706282673976" } ], "assets": [], "management": [] } } }, "Errors": [ { "Reasons": [ { "Code": "ManagedAppDistribution.ManagedAppDistributionError.0", "Description": "The operation couldn’t be completed. (ManagedAppDistribution.ManagedAppDistributionError error 0.)" } ], "StatusItem": "app.managed.list" } ] } Note : The ManagedAppDistribution framework extension appears to not be implemented in this context. Kindly help us with this issue. Thanks in advance.

Is there a limit to the size of the object that you are wanting to capture with Object Capture. e.g could it capture a horse or other such sized animal?

hi,there are some questions about Privacy manifest 1.why do we just see the information about app's manifest in PrivacyReport after app has been archived,that does not contain our SDK's manifest info.but our frameworks that app contains have manifest. 2.does every SDK need to add manifest if this SDK collects user data or uses API? 3.there is list of third-part-sdk https://developer.apple.com/support/third-party-SDK-requirements/ ,if we use an SDK not listed and the sdk has collected use data or used api that need to display reason,should we add manifest file?

Why does the bit rate of MV-HEVC videos recorded by iPhone double? Is there some depth information hidden in MV-HEVC?

I'd love to play around with DockKit, but I didn't see anything mentioned about hardware. I'm assuming Apple isn't releasing their own motorized dock and haven't seen anything about how to get hardware recognized by the accessory manager. I'd like to prototype a dock myself using esp32 and some stepper motors. I've already got this working with bluetooth communication from iOS via CoreBluetooth, but I don't know if there's specific service and characteristic UUIDs that the system is looking for to say it's compatible with DockKit? Would really love to start playing with this, anyone got any insights on how to get up and running?

WWDC23 Platform State of the Union mentioned that Volume shutter buttons to trigger the camera shutter is coming later this year. This was mentioned at 0:30:15. Would anyone know when this will be available?

My app is using SwiftData, but I deployed it to the app store with no VersionedSchema applied without thinking about migrating the model. Now I need to migrate the data and I need help from someone who has experience moving from non-versioned to versioned. Assuming I currently have a version1, version2 schema, it works fine for the initial install situation, but when I migrate to version1, version2 in an app that is listed on the app store, I run into problems. I don't have any logs to show for it. Thread 1: EXC_BAD_ACCESS (code=2, address=0x16a6578f0) If anyone has had the same experience as above, please respond, thanks! Let me know what kind of logs you need and I'll add them as a comment.

I'm currently using Swiftdata to store data for an app I've deployed to the app store. The problem is that the app does not build when I add a case of the Enum type to the model, so I decided to apply a MigrationPlan. I also decided that it is not a good idea to store the Enum type itself because of future side effects. The app is deployed in the app store with a model without a VersionedSchema, so the implementation is complete until we modify it to a model with a VersionedSchema. This is Version1. public enum TeamSchemaV1: VersionedSchema { public static var versionIdentifier: Schema.Version = .init(1, 0, 0) public static var models: [any PersistentModel.Type] { [TeamSchemaV1.Team.self, TeamSchemaV1.Lineup.self, TeamSchemaV1.Player.self, TeamSchemaV1.Human.self] } @Model public final class Lineup { ... public var uniform: Uniform ... } And you're having trouble migrating to Version2. The change is to rename the Uniform to DeprecatedUniform (the reason for the following change is to migrate even if it's just a property name) public enum TeamSchemaV2: VersionedSchema { public static var versionIdentifier: Schema.Version = .init(1, 0, 1) public static var models: [any PersistentModel.Type] { [TeamSchemaV2.Team.self, TeamSchemaV2.Lineup.self, TeamSchemaV2.Player.self, TeamSchemaV2.Human.self] } @Model public final class Lineup { ... @Attribute(originalName: "uniform") public var deprecatedUniform: Uniform ... When you apply this plan and build the app, EXC_BAD_ACCESS occurs. public enum TeamMigrationPlan: SchemaMigrationPlan { public static var schemas: [VersionedSchema.Type] { [TeamSchemaV1.self, TeamSchemaV2.self] } public static var stages: [MigrationStage] { [migrateV1toV2] } public static let migrateV1toV2 = MigrationStage.lightweight(fromVersion: TeamSchemaV1.self, toVersion: TeamSchemaV2.self) } I'm currently unable to migrate the data, which is preventing me from updating and promoting the app. If anyone knows of this issue, I would really appreciate your help.

Is it possible to use ImageAnalysisInteraction as discussed in WWDC23 "Lift subjects from images in your app" using Objective-C?

It appears that for a successful registration of a passkey to a relying party using passkey autofill provider, the BE BS bits/flags in the attestation response need to be set to true. Please refer FLAGS byte of authData field part of attestationObject mentioned here - https://www.w3.org/TR/webauthn-2/#sctn-attestation. If those flags are set to false, the RP rejects saying - "The operation either timed out or was not allowed. See: https://www.w3.org/TR/webauthn-2/#sctn-privacy-considerations-client." What are the implications of having those flags set to true? Does it make the generated passkey syncable across devices using same apple id? If yes, is there at all anyway possible by which a generated passkey can be made device bound, basically can be generated and used only on a single iPhone/iOS device? Also, is there a plan to ever make those flags to be set to false in a future iOS release? Also, what does it mean in the credential provider popup where it says - "Available where is installed." in the below screenshot?

I am trying to implement a third party passkey credential provider and I have been able to successfully setup the project for that. Below is a sample code which I am using - let passkeyRegistrationCredential = ASPasskeyRegistrationCredential(relyingParty: self.request?.credentialIdentity.serviceIdentifier.identifier ?? "", clientDataHash: self.request?.clientDataHash ?? Data(), credentialID: Data(credentialId), attestationObject: Data(attestationBytes) self.extensionContext.completeRegistrationRequest(using: passkeyRegistrationCredential) The attestationBytes object that I am generating and sending back to RP seems to work only if I set the "fmt" to "none", which basically requires "attStmt" to be sent as an empty value as per WebAuthn spec - https://www.w3.org/TR/webauthn-2/#sctn-none-attestation When trying to set the "fmt" to "packed" in attestation object and creating a self signed "attStmt" consisting of "alg" and "sig" key-values referring - https://www.w3.org/TR/webauthn-2/#sctn-packed-attestation, it does not seem to work. The RP throws an error. I do not have "x5c" object as that supposedly is not mandatory in case of self attestation. I have "authData" also as part of the response properly setup. Is it not possible to use packed attestation or am I missing something in creating the attestation object? Also, does Apple modify the response being sent in the background before sending to RP if packed fmt is used?

I've been trying to reproduce the example used in the WWDC 23 Presentation "Explore Pit Charts and Interactivity in SwiftCharts" where a popover annotation is set on top of the chart and vertical; RuleMark. However when doing so the annotation doesn't appear at all. I worked around that issue by setting: y: .fit(to: .chart) in the init of the overflowResolution, like: .annotation(position: .top, spacing: 0, overflowResolution: .init(x: .fit(to: .chart), y: .fit(to: .chart))) Probably a SwiftUI bug given this API is only a few months old. If anyone has been able to reproduce that example let me know!

Hello Apple Community, I've been delving into the realm of time-based activation predicates through DDM. In my recent pursuits, I've been experimenting with the device's local time to evaluate a predicate expression and apply activation configurations. Is it possible to achieve this? Our DDM currently leverages device status items and server management properties to activate predicates. These predicates come to life when the logic becomes true, initiating activations seamlessly. While the Apple Predicate Guide provides a solid foundation, I've encountered some challenges when it comes to time-based expressions. The guide covers basics such as context and numerical-based predicates, but I find myself seeking more clarity on implementing time-based logic effectively. If any of you have insights, tips, or experiences to share regarding time-based activation predicates expressions in declarative device management, your input would be immensely valuable. I'm particularly interested in understanding practical approaches and gaining a deeper comprehension of the nuances involved. Thank you in advance.

Hi there, I have watched the keynote of WWDC23 and like to have technical information on how to implement Filling forms for iPad OS using PDFKIT into our App. I have reviewed PDFKit API documentation, but there are no any documentation about how to use that technology and no any changes to API. Thanks, Eduard

I have developed an interactive widget which looks as the following It is using CoreData. The view is implemented as the following struct widget_extensionEntryView : View { var body: some View { if let nsTodoList = nsTodoList { VStack(alignment: .leading, spacing: 1) { ... ForEach(0..<prefixGoodNSTodoArray.count, id: \.self) { index in ... let todoIntent = TodoIntent(objectIDAsString: objectIDAsString, parentOrder: parentOrder) Button(intent: todoIntent) { } } } } } } The AppIntent is implemented as the following import Foundation import AppIntents import WidgetKit import CoreData struct TodoIntent: AppIntent { static var title: LocalizedStringResource = "Complete Task" static var description: IntentDescription = IntentDescription("Complete selected task") @Parameter(title: "objectIDAsString") var objectIDAsString: String @Parameter(title: "parentOrder") var parentOrder: Int init() { } init(objectIDAsString: String, parentOrder: Int) { self.objectIDAsString = objectIDAsString self.parentOrder = parentOrder } func perform() async throws -> some IntentResult { guard let objectID = NSManagedObjectID.from(objectIDAsString) else { return .result() } guard let nsTodoList = NSTodoListRepository.INSTANCE.getNSTodoList(objectID) else { return .result() } nsTodoList.toggleChecked(context: CoreDataStack.INSTANCE.viewContext, parentOrder: Int64(parentOrder)) RepositoryUtils.saveContextIfPossible(CoreDataStack.INSTANCE.viewContext) TodoWidgetOptions.isWrittenByWidgetExtension = true // Refresh all home widgets. // TODO: https://developer.apple.com/forums/thread/721937 WidgetCenter.shared.reloadAllTimelines() return .result() } } The interactive widget works pretty well. However, tapping on the widget has no response in the following situations: After an overnight, we turn on the iPhone's screen and tap on the widget. After a few hours of idle time, we turn on the iPhone's screen and tap on the widget. One of the steps below will make the widget workable again: Launch and close the main app again. The main app will call WidgetCenter.shared.reloadAllTimelines() during sceneDidEnterBackground. Press and hold on the widget, choose 'Edit widget', and select the desired Todo list. One thing to take note of is that I am using IntentTimelineProvider instead of AppIntentTimelineProvider. The reason I am using 'older tech' is due to the limitation mentioned in https://developer.apple.com/forums/thread/741053 However, I am not sure whether this is the root cause of the problem. Does anyone have any idea why such a problem occurs? Thanks.

I provide a website, which can be added to Home screen. Does Apple support dynamic widgets that can be added to Home screen for web apps? Also, can these widgets be updated by setting update frequency as described on Apple page: https://developer.apple.com/design/human-interface-guidelines/widgets ?

I have an iOS app target with a framework dependency and want to merge that framework by setting MERGED_BINARY_TYPE to automatic in the app target's build settings. It all works fine until I add a (non-private) UIHostingController to the framework target. When I do this it crashes on startup with this message: dyld[15894]: Symbol not found: _OBJC_CLASS_$__TtC5Frame4MyVC. Xcode 15.1b3 Reported as bug via Feedback Assistant: FB13379276
