How to Share and Access Dynamically Updating Data Across Different Targets?
I have a app with two targets: a main DeviceActivityApp target and a DeviceReport target. In the DeviceReport target, I have a TotalActivityReport struct conforming to DeviceActivityReportScene. Inside its makeConfiguration method, I update a dynamically generated list of AppReport items. The list updates correctly in the DeviceReport target. // Define which context your scene will represent. let context: DeviceActivityReport.Context = .totalActivity // Define the custom configuration and the resulting view for this report. let content: (MonitorDeviceReport) -> TotalActivityViewFirst @ObservedObject var activityData:ActivityData func makeConfiguration(representing data: DeviceActivityResults<DeviceActivityData>) async -> MonitorDeviceReport { // Reformat the data into a configuration that can be used to create // the report's view. var appList:[AppsReport]=[] let totalActivityDuration = await data.flatMap { $0.activitySegments }.reduce(0, { $0 + $1.totalActivityDuration }) for await _data in data{ for await activity in _data.activitySegments{ for await category in activity.categories{ for await app in category.applications{ let name=app.application.localizedDisplayName ?? "No Name" let bundleId=app.application.bundleIdentifier ?? "nil" let duration=app.totalActivityDuration let appIcon=app.application.token let app=AppsReport(id:bundleId,duration:duration, name:name, icon:appIcon) appList.append(app) } } } } DispatchQueue.main.async { activityData.list=appList } return MonitorDeviceReport(duration:totalActivityDuration, apps:appList) } } public class ActivityData:ObservableObject{ @Published var list:[AppsReport]=[] public static let shared = ActivityData() }. // This is in MonitorReport target However, I need to access this dynamic list in my MyApp target, specifically in ContentView.swift. I tried using an ObservableObject (ActivityData) to share the data between targets, but the list always appears empty in the MyApp target. Here’s what I’ve tried so far: Created a shared ActivityData instance using @Published Passed the ActivityData instance to TotalActivityReport Used dependency injection and a singleton pattern for ActivityData Verified that makeConfiguration updates the list correctly in DeviceReport What could I be missing? How can I correctly share and access this data across targets?

To resolve this issue, please revise the app preview to only use video screen captures of the app. These may include narration and video or textual overlays for added clarity

Issue with Siri Not Displaying Prompt in App Intent
Hello everyone, I'm currently working on an App Intent for my iOS app, and I’ve encountered a frustrating issue related to how Siri prompts for a category selection. Here’s an overview of what I’m dealing with: extension Category: AppEntity, @unchecked Sendable { var displayRepresentation: DisplayRepresentation { DisplayRepresentation(title: "\(name)") } static var typeDisplayRepresentation = TypeDisplayRepresentation(name: "Category") typealias DefaultQueryType = ShortcutsCategoryQuery static var defaultQuery: ShortcutsCategoryQuery = ShortcutsCategoryQuery() } struct ShortcutsCategoryQuery: EntityQuery { func entities(for identifiers: [String]) async throws -> [Category] { let context = await ModelContext(sharedModelContainer) let categories = try CategoryDataProvider(context: context).getItems() return categories.filter { identifiers.contains($0.id) } } func entities(matching string: String) async throws -> [Category] { return try await suggestedEntities() } func suggestedEntities() async throws -> [Category] { let context = await ModelContext(sharedModelContainer) do { let categories = try CategoryDataProvider(context: context).getItems() if categories.isEmpty { print("No categories found.") } return categories.map { category in Category( id: category.id, name: category.name, stringSymbol: category.stringSymbol, symbol: category.symbol, stringColor: category.stringColor, color: category.color ) } } catch { print(error) return [] } } } The issue arises when I use Siri to invoke the intent. Siri correctly asks me to select a category but does not display any options unless I said something that Siri recognized, like "Casa(House) or *****(Test)" in portuguese. Only then does it show the list of available categories. I would like the categories to appear immediately when Siri asks for a selection. I've already tried refining the ShortcutsCategoryQuery and debugging various parts of my code, but nothing seems to fix this behavior.

Handle InSendMessageIntent in the app
Hi, I'm implementing InSendMessageIntent handling in our app. I can handle InSendMessageIntent through extension, but handling also includes business logic like authorisation status and some heavy operation which I can't expose from the main target. I tried to handle it in-app, but func application(_ application: UIApplication, handlerFor intent: INIntent) -> Any? didn't trigger. At the first glance the configuration looks correct - the InSendMessageIntent is added under INIntentsSupported and UIApplicationSupportsMultipleScenes is set to YES in info.plist. After that reply with message button disappeared from the incoming Voip callKit screen. So I had a question - Is this intent possible to be handled in-app?

How to add a reoccurring Hebrew Event to a calendar.
Currently Apple has their own calendar called Birthdays which takes the birthdays from contacts and makes it as a regular calendar event along with the birthday number, they even do this for Hebrew Birthdays. I have tried (unsuccessfully thus far) to take the same concept and create a calendar for reoccurring events on a specific date in the Hebrew Calendar. An example of this would be Yahrtzeits, which is observed on the Hebrew date each year after a person dies. I want to add it to the system calendars like how Apple does it this way it can be used with any app not just my own. Currently there isn't a way to specify the calendar (like Calendar(identifier: .hebrew) or even make a custom EKRecurrenceRule, also from some of the debugging of the Birthdays calendar, it seems that the date saved is the Gregorian date and that theres some internal calculations happening. Is there a way to add reoccurring Hebrew Events or do I need to reinvent the wheel?

Premature DeviceActivityEvent Triggering
Our app monitors device usage and applies a shield when the set time limit is reached. Multiple DeviceActivitySchedules can be present, each with different time limits. To display notifications at 50% of the total limit for each DeviceActivitySchedule, we set a warning time at half of the total time. However, we occasionally receive premature event callbacks. For example, consider a schedule from 13:00 to 13:30 with a single event threshold at 10 minutes and a warning time of 5 minutes. The 'eventDidReachThreshold' callback is delivered prematurely, along with the 'eventWillReachThresholdWarning' callback, at 13:10. Additionally, in some cases, when one DeviceActivitySchedule ends and the next begins immediately, DeviceActivityEvents registered for the new DeviceActivitySchedule are delivered prematurely along with the schedule start callback. For example, consider there are two DeviceActivitySchedules from 12:00 to 13:00 and from 13:00 to 14:00, each with a limit of 10 minutes and a warning time of 5 minutes. When the first schedule ends and the next begins at 13:00, the 'eventDidReachThreshold' callbacks for the events registered in the second schedule are delivered prematurely, along with the 'intervalDidStart' callback.

Where in App Store are BG asset's keys visible: BAEssentiaMaxInstallSize / BAMaxInstallSize
The background asset keys (BAEssentiaMaxInstallSize/BAMaxInstallSize) referenced in the app's Info.plist will be displayed to users on the App Store, as outlined in the WWDC video and supported by Apple’s documentation. Could you please clarify where exactly on the App Store's product page these values will be visible? Is the size displayed on the App Store a sum of the app bundle size and the size specified in these keys within the Info.plist?

Issue with handoff between Siri intent, iOS app & CarPlay extension
We are experiencing an infrequent issue with the handoff between our Siri intent, our iOS app, and our CarPlay extension. Siri correctly understands the request, and the handler(for intent: INIntent) method is called. In the final step, we respond using: INStartCallIntentResponse(code: .continueInApp, userActivity: userActivity) with an instance of NSUserActivity initialized as: NSUserActivity(activityType: "our.unique.StartCallIntent") This "our.unique.StartCallIntent" type is included in the app’s NSUserActivityTypes attribute within the Info.plist. The callback is handled in the main view of the app through: view.onContinueUserActivity("our.unique.StartCallIntent", perform: handleSiriIntent) Additionally, we handle the callback in the CarPlay extension using: func scene(_: UIScene, continue userActivity: NSUserActivity) This is necessary because when Siri is invoked while CarPlay is active, the CarPlay extension should receive the callback. Most of the time, both callbacks are triggered as expected. However, on rare occasions, the handoff fails, and neither onContinueUserActivity nor scene(_: UIScene, continue userActivity:) receives a callback from the Siri intent. Is this a known issue? If so, are there any guidelines or best practices for ensuring that our Siri intent handoff consistently triggers the callbacks?

iOS universal links: excluded path opens in my app
Hello. Here is my AASA file (my appID changed): { "applinks": { "apps": [], "details": [ { "appIDs": [ "A123B4567C.app.myapp.tool" ], "components": [ { "/": "/en", "exclude": true }, { "/": "/en/*", "exclude": true }, { "/": "/workspace/*", "exclude": true }, { "/": "*" } ], "paths": [ "NOT /en", "NOT /en/*", "NOT /workspace/*", "*" ] } ] } } I need to open all links with my app except those with excluded flag. When I open 'right' links, my app opens them (that's great). When I open excluded link (e.g. https://myapp.app/workspace/personal) Safari opens it (that's great) but then the app is launched (that's what not expected). What I already checked: added the old "paths" property (it wasn't there originally) rebooted my device reinstalled my app from the TestFlight then from the AppStore asked ChatGPT used AASA validator (branch.io one) cleared Safari cache checked my links for redirects What else can I check? Thanks.

App with iMessage extension AND sticker pack
Im not a dev but trying to create something trying to create an app that includes an iMessage extension AND a sticker pack. My first attempt I tried to create a iMessage app but apparently I cant include a sticker pack. Ive tried to create a shell app with a sticker pack and iMessage extension but it's just not working. Can someone please let me know how I can do this. How can I get an iMessage extension app and a sticker pack installed at the same time from the same app. Ive tried everything, tried creating a seperate iOS app with sticker pack and iMessage extension and nothing. A lot of times a get an error like "CompileAssetCatalogVariant failed with a nonzero exit code"" If I remove the sticker pack builds successfully. thank you in advance

Should new apps use AudioPlaybackIntent or INPlayMediaIntent?
WWDC videos suggest that existing apps should continue using the old SiriKit domains, such as INPlayMediaIntent. But what about new apps for playing audio? Should we implement Siri functionality for audio playback using the old SiriKit domains, or should we create our own AppEntities and trigger them via custom AudioPlaybackIntent implementations? Interactive widgets require an AppIntent and don’t support the old INPlayMediaIntent. To achieve the same functionality as the Music app widgets, it seems logical to adopt the new AudioPlaybackIntent. However, I can't find any information about this in the documentation.

iPhone mirroring screen switching (request & question)
iPhone mirroring is available from macOS 15. When running an app with iPhone mirroring Can I know whether the app currently being mirrored is running at the top of the Mac app or screen? Or is there a way to know whether it is hidden by another app on the Mac or re-displayed? If not, I hope it will be added in a future update. And I hope there is an API that can tell whether the current app is connected to iPhone mirroring or not.

iOS App terminates but does not generate Crash Report
The app exits immediately on startup, there is no crash message, and I can't get any valuable diagnostic information. It doesn't even get to the main function. It feels like exit is being called somewhere, and then I used atexit to register the relevant handler. Finally, I found the following stack printout It looks like it's a dynamic linking issue, so what's the best way to troubleshoot it. This problem only occurs in release versions.

Checking Equality of ApplicationToken Instances in Swift
Hi everyone, I'm working on a Swift application and trying to determine whether an application has exceeded its limit based on an ApplicationToken. I have the following function to check if the current app's token matches any of the tokens stored when the app limit is reached: private func isAppLimitExceeded(for application: Application?) -> Bool { guard let application = application, let appToken = application.token else { return false } let exceededTokens = configManager.getAppLimitExceededTokens() return exceededTokens.contains { exceededToken in appToken == exceededToken } } The function configManager.getAppLimitExceededTokens() returns a list of [ApplicationToken] that were saved in UserDefaults when an app limit is reached. The goal is to use the isAppLimitExceeded method to verify if the current shield for the app is triggered due to a limit/threshold being exceeded. This function is part of a class that conforms to the ShieldConfigurationDataSource protocol: class ShieldConfigurationExtension: ShieldConfigurationDataSource { // ... } My concern is whether comparing two ApplicationToken instances using == is a reliable method for determining if they are equal. Are ApplicationToken objects guaranteed to be comparable with == out of the box, or do I need to implement Equatable or another method of comparison? Could there be issues with tokens stored in UserDefaults not matching due to reference or serialization differences? Any guidance on how to ensure proper comparison of these tokens would be appreciated! Thanks!
