Hello, Could you please provide details for maximum string length of the prompt and the title when using ImageCreator and the method extracted(from:title:)? static func extracted( from text: String, title: String? = nil ) -> ImagePlaygroundConcept Any additional details or example of prompt and title would help. Additionally, are ImagePlaygroundStyle.animation, ImagePlaygroundStyle.illustration and ImagePlaygroundStyle.sketch all available when using extracted(from:title:)? I am trying to generate images programmatically and would appreciate your guidance. Thank you.

Every time I touch (add a key, remove a key, even add a key, then remove it) the Strings Catalog .xcstrings file, it re-renders the entire file and creates a 18 thousand line dif. When I looked closer, it changes the whitespace before colons! "version": "1.0" "version" : "1.0" it does so for every JSON node. This makes the whole feature useless, because we wont be able to see what we changed upon code review (diff is unprintable in the github interface) and every time we change a single translation, we will be stacking 18k lines diff. Not to mention merge conflicts?

Hi, we have developed an application that streams data from two BLE peripherals at a rate of 14.5kbps per peripheral. Until now, our devices streamed in near real time with no lag on all Apple devices with Bluetooth 5.0 or greater. Since the release of the iPhone 17 series and the iPad A16, we have reports from users of the data being streamed at significantly lower rates than expected. Any help here would be greatly appreciated as our customers are being affected by this change.

Hi, I want to recreate a chart from Apple Health and I have code like this. When I scroll - especially the week and month charts, there are performance issues. If I remove .chartScrollPosition(x: $scrollChartPosition), it runs smoothly, but I need to know which part of the chart is currently displayed. Can you help me? import Charts import SwiftUI struct MacroChartView: View { var selectedRange: ChartRange var binnedPoints: [MacroBinPoint] @State private var scrollChartPosition: Date = .now var body: some View { VStack { Text("\(selectedRange.rangeLabel(for: scrollChartPosition))") Chart(binnedPoints) { point in BarMark( x: .value("Date", point.date, unit: selectedRange.binComponent), y: .value("Calories", point.calories) ) } .frame(height: 324) .chartXVisibleDomain(length: selectedRange.visibleDomainLength()) .chartScrollableAxes(.horizontal) .chartScrollPosition(x: $scrollChartPosition) .chartScrollTargetBehavior(.valueAligned(matching: selectedRange.scrollAlignmentComponents)) .chartXAxis { switch selectedRange { case .week: AxisMarks(values: .stride(by: .day)) { date in AxisGridLine() AxisTick() AxisValueLabel(format: .dateTime.weekday(.abbreviated)) } case .month: AxisMarks(values: .stride(by: .weekOfYear)) { date in AxisGridLine() AxisTick() AxisValueLabel(format: .dateTime.day()) } case .halfYear: AxisMarks(values: .stride(by: .month)) { date in AxisGridLine() AxisTick() AxisValueLabel(format: .dateTime.month(.abbreviated)) } case .year: AxisMarks(values: .stride(by: .month)) { date in AxisGridLine() AxisTick() AxisValueLabel(format: .dateTime.month(.abbreviated)) } } } } } } enum MeasurementHistoryMode { case macros case comparisons } enum MacroKindToDisplay { case protein, fat, carbs } enum MacrosDisplayMode: Equatable { case all case single(MacroKindToDisplay) } enum ChartRange: String, CaseIterable { case week = "T" case month = "M" case halfYear = "6M" case year = "R" var binComponent: Calendar.Component { switch self { case .week, .month: return .day case .halfYear: return .weekOfYear case .year: return .month } } var scrollAlignmentComponents: DateComponents { switch self { case .week: return DateComponents(hour: 0, minute: 0, second: 0) case .month: return DateComponents(hour: 0) case .halfYear: return DateComponents(weekday: 1) case .year: return DateComponents(day: 1) } } func visibleDomainLength() -> Int { switch self { case .week: return 7 * 24 * 60 * 60 case .month: return 31 * 24 * 60 * 60 case .halfYear: return 6 * 31 * 24 * 60 * 60 case .year: return 12 * 31 * 24 * 60 * 60 } } func start(for date: Date) -> Date { let cal = Calendar.current switch self { case .week, .month: return cal.startOfDay(for: date) case .halfYear: return cal.dateInterval(of: .weekOfYear, for: date)?.start ?? cal.startOfDay(for: date) case .year: return cal.dateInterval(of: .month, for: date)?.start ?? cal.startOfDay(for: date) } } func rangeLabel(for start: Date) -> String { let end = start.addingTimeInterval(TimeInterval(visibleDomainLength())) let f = DateFormatter() f.dateFormat = Calendar.current.isDate(start, inSameDayAs: end) ?

Hello there, Our application has HLS VOD download option. Users can download VOD which has DRM protection and watch content when device is offline. We use aggregateAssetDownloadTask to download HLS VOD. We want to resume download after Wifi/LTE change but it does not resume. Download is starting from beginning. We use some token algorithms to start download. That's why, our playlist url and chunks urls may change. But playlist and chunk urls' content is unique. If user start to download via Wifi and changed to LTE. Download request responds 403 Forbidden because of some token algorithms after some time func urlSession(_ session: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) AVAssetDownloadDelegate function triggered by system. If we resume it does not resume at this point. It is starting from beginning if we start new download process for same content. Is there any way to resume unfinished HLS Download processes? Thanks

I’m working toward an official release of our application. The app is designed to interface with peripheral devices, which means users need both the mobile app and the peripheral devices to log in and use it. Because of that, how would the review process work when I get to that point?

Issue: Push notifications are not being received for some users. What could be the possible causes? Push notifications are being sent from our own server, and we are receiving success responses from APNS. Users have confirmed that notifications are enabled on their devices, and they report no network issues.

I'm building a Capacitor iOS app with a plain <video> element playing an MP4 file inline. I want Picture-in-Picture to activate automatically when the user goes home — swipe up from the bottom edge of the screen (on an iPhone with Face ID) or press the Home button (on an iPhone with a Home button). Fullscreen → background works perfectly — iOS automatically enters Picture-in-Picture. But I need this to work from inline playback without requiring the user to enter fullscreen first. Setup <video id="video" playsinline autopictureinpicture controls src="http://podcasts.apple.com/resources/462787156.mp4"> </video> // AppDelegate.swift let audioSession = AVAudioSession.sharedInstance() try? audioSession.setCategory(.playback, mode: .moviePlayback) try? audioSession.setActive(true) UIBackgroundModes: audio in Info.plist allowsPictureInPictureMediaPlayback is true (Apple default) iOS 26.3.1, WKWebView via Capacitor What I've tried 1. autopictureinpicture attribute <video playsinline autopictureinpicture ...> WKWebView doesn't honor this attribute from inline playback. It only works when transitioning from fullscreen. 2. requestPictureInPicture() on visibilitychange document.addEventListener('visibilitychange', () => { if (document.visibilityState === 'hidden' && !video.paused) { video.requestPictureInPicture(); } }); Result: Fails with "not triggered by user activation". The visibilitychange event doesn't count as a user gesture. 3. webkitSetPresentationMode('picture-in-picture') on visibilitychange document.addEventListener('visibilitychange', () => { if (document.visibilityState === 'hidden' && !video.paused) { video.webkitSetPresentationMode('picture-in-picture'); } }); Result: No error thrown. The webkitpresentationmodechanged event fires with value picture-in-picture. But the PIP window never actually appears. The API silently accepts the call but nothing renders. 4. await play() then webkitSetPresentationMode document.addEventListener('visibilitychange', async () => { if (document.visibilityState === 'hidden') { await video.play(); video.webkitSetPresentationMode('picture-in-picture'); } }); Result: play() succeeds (audio resumes in background), but PIP still doesn't open. 5. Auto-resume on system pause + PIP on visibilitychange iOS fires pause before visibilitychange when backgrounding. I tried resuming in the pause handler, then requesting PIP in visibilitychange: video.addEventListener('pause', () => { if (document.visibilityState === 'hidden') { video.play(); // auto-resume } }); document.addEventListener('visibilitychange', () => { if (document.visibilityState === 'hidden' && !video.paused) { video.webkitSetPresentationMode('picture-in-picture'); } }); Result: Audio resumes successfully, but PIP still doesn't open. 6. Native JS eval from applicationDidEnterBackground func applicationDidEnterBackground(_ application: UIApplication) { webView?.evaluateJavaScript( "document.querySelector('video').requestPictureInPicture()" ) } Result: Same failure — no user activation context. Observations The event order on background is: pause → visibility: hidden webkitSetPresentationMode reports success (event fires, no error) but the PIP window never renders requestPictureInPicture() consistently requires user activation, even from native JS eval Audio can be resumed in background via play(), but PIP is a separate gate Fullscreen → background automatically enters Picture-in-Picture, confirming the WKWebView PIP infrastructure is functional Question Is there any way to programmatically enter PIP from inline playback when a WKWebView app goes to background? Or is this intentionally restricted by WebKit to fullscreen-only transitions? Any pointers appreciated. Thanks!

Precondition: In system settings, scale the pointer size up to the max. Our SCScreenshotManager code currently works in macOS 15 and earlier to capture the cursor at it's larger size, but broke in one of the minor releases of macOS Tahoe. The error it produces now is "Failed to start stream due to audio/video capture failure". This only seems to happen with the cursor window, not any others. Another way to get the cursor is with https://developer.apple.com/documentation/appkit/nscursor/currentsystem, but that is now deprecated, which makes me think the capture of the cursor is being blocked deliberately. We see this as a critical loss of functionality for our apps, and could use guidance on what to use instead.

Hello, I'm using videotoolbox superresolution API in MACOS 26: https://developer.apple.com/documentation/videotoolbox/vtsuperresolutionscalerconfiguration/downloadconfigurationmodel(completionhandler:)?language=objc, when using swift, it's ok, when using objective-c, I get error when downloading model with downloadConfigurationModelWithCompletionHandler: [Auto] MA-auto{_failedLockContent} | failure reported by server | error:[com.apple.MobileAssetError.AutoAsset:MissingReference(6111)] [Auto] MA-auto{_failedLockContent} | failure reported by server | error:[com.apple.MobileAssetError.AutoAsset:UnderlyingError(6107)_1_com.apple.MobileAssetError.Download:47] Download completion handler called with error: The operation couldnxe2x80x99t be completed.

We made an update of one of our games with the Declared Age Range framework, and one of the users contacted us, asking how could he confirm his age to access the app's features. Meaning that isEligibleForAgeFeatures returned true on his device. According to documentation: Use isEligibleForAgeFeatures to determine whether associated laws or regulations may apply to your app based on the person’s location and account settings. This property returns true when your app needs to support Age Assurance for the current user. As far as we know, the laws are not applied anywhere yet. So, why did isEligibleForAgeFeatures return true?

I encountered an error when trying to rollback context after deleting some model with multiple one-to-many relationships when encountered a problem later in a deleting method and before saving the changes. Something like this: do { // Fetch model modelContext.delete(model) // Do some async work that potentially throws try modelContext.save() } catch { modelContext.rollback() } When relationship is empty - the parent has no children - I can safely delete and rollback with no issues. However, when there is even one child when I call even this code: modelContext.delete(someModel) modelContext.rollback() I'm getting a fatal error: SwiftData/ModelSnapshot.swift:46: Fatal error: Unexpected backing data for snapshot creation: SwiftData._FullFutureBackingData<ChildModel> I use ModelContext from within the ModelActor but using mainContext changes nothing. My ModelContainer is quite simple and problem occurs on both in-memory and persistent storage, with or without CloudKit database being enabled. I can isolate the issue in test environment, so the model that's being deleted (or any other) is not being accessed by any other part of the application. However, problem looks the same in the real app. I also changed the target version of iOS from 18.0 to 26.0, but to no avail. My models look kind of like this: @Model final class ParentModel { var name: String @Relationship(deleteRule: .cascade, inverse: \ChildModel.parent) var children: [ChildModel]? init(name: String) { self.name = name } } @Model final class ChildModel { var name: String @Relationship(deleteRule: .nullify) var parent: ParentModel? init(name: String) { self.name = name } } I tried many approaches that didn't help: Fetching all children (via fetch) just to "populate" the context Accessing all children on parent model (via let _ = parentModel.children?.count) Deleting all children reading models from parent: for child in parentModel.children ?? [] { modelContext.delete(child) } Deleting all children like this: let parentPersistentModelID = parentModel.persistentModelID modelContext.delete(model: ChildModel.self, where: #Predicate { $0.parent.persistentModelID == parentPersistentModelID }, includeSubclasses: true) Removing @Relationship(deleteRule: .nullify) from ChildModel relationship definition I found 2 solution for the problem: To manually fetch and delete all children prior to deleting parent: let parentPersistentModelID = parentModel.persistentModelID for child in try modelContext.fetch(FetchDescriptor<ChildModel>(predicate: #Predicate { $0.parent.persistentModelID == parentPersistentModelID })) { modelContext.delete(child) } modelContext.delete(parentModel) Trying to run my code in child context (let childContext = ModelContext(modelContext.container)) All that sounds to me like a problem deep inside Swift Data itself. The first solution I found, fetching potentially hundreds of child models just to delete them in case I might need to rollback changes on some error, sounds like awful waste of resources to me. The second one however seems to work fine has that drawback that I can't fully test my code. Right now I can wrap the context (literally creating class that holds ModelContext and calls its methods) and in tests for throwing methods force them to throw. By creating scratch ModelContext I loose that possibility. What might be the real issue here? Am I missing something?

Hi everyone, I'm new to visionOS development. I'm trying to create a physics-based scene (with gravity) where users can pick up and move objects on a workbench. I am struggling with physics interactions during the drag gesture: Kinematic Mode: If I switch to .kinematic during the drag, the object moves smoothly but clips through other objects (no collisions). Dynamic Mode: I tried keeping it .dynamic and applying linear velocity toward the hand position, but the movement feels laggy and unresponsive. Hybrid Approach: I tried switching to .kinematic during DragGesture.onChange and back to .dynamic on collision, but this causes the entity to jitter/shake violently when touching other objects. Has anyone found a clean way to drag objects while maintaining solid collisions. Thanks for your help!

I am getting bug reports from users that occasionally the AlarmKit alarms scheduled by my app are going off exactly at midnight. In my app, users can set recurring alarms for sunrise/sunset etc. I implement this as fixed schedule alarms over the next 2-3 days with correct dates pre-computed at schedule time. I have a background task which is scheduled to run at noon every day to update the alarms for the next 2-3 days. Are there any limitations to the fixed schedule which might be causing this unintended behavior of going off at midnight?

I would like to confirm this one way or another. I believe that re-downloaders are not included based on those links: https://developer.apple.com/help/app-store-connect/view-app-analytics/view-product-page-optimization-results https://developer.apple.com/help/app-store-connect/reference/reporting/app-metrics (Download metrics section). In our apps 20-30% of downloads are from re-downloaders. Thank you!

I've been rejected a couple of times for Guidelines 5.1.1(i) and 5.1.2(i) regarding third-party AI data sharing consent. Each time, the reviewer states they cannot see the consent prompt, even though it is the first screen displayed on every app launch. My app (GymFusion) uses Anthropic's Claude AI for features like meal scanning, body composition analysis, and workout coaching. Here is exactly what I've implemented: IN-APP CONSENT (embedded in view hierarchy, not a sheet/popup): In my RootView.swift, the consent is a conditional view that blocks the entire app: } else if !consentManager.hasConsented && !consentManager.hasSeenConsent { AIConsentView() } else if auth.isAuthenticated { MainTabView() } The hasSeenConsent flag is reset to false on every app launch in the App's init(), so the consent screen appears on every launch until the user accepts: init() { UserDefaults.standard.set(false, forKey: "user_ai_consent_seen") AIConsentManager.shared.hasSeenConsent = false FirebaseApp.configure() } THE CONSENT SCREEN INCLUDES: Lists all personal data shared (meal photos, water glass photos, workout history, progress photos, body measurements, fitness profile) Names Anthropic, PBC (Claude AI) as the third-party recipient 3 required acknowledgment checkboxes that must all be checked before "I Agree" is enabled Cannot be swiped away (.interactiveDismissDisabled) "Decline" lets user proceed but consent reappears next launch Users can revoke consent anytime in More tab PRIVACY POLICY INCLUDES: Names Anthropic as third-party AI provider Lists all data collected and shared States Anthropic provides "same or equal protection of user data" Explains consent and revocation process Link: https://ahmedali420911.github.io/gymfusion-legal/privacy-policy.html WHAT THE REVIEWER SAYS EACH TIME: "We were not presented with the consent prompt on launch or anywhere else in the app." WHAT I'VE VERIFIED: Aiconsentview.swift is in the Xcode build target (confirmed in project.pbxproj with 4 references) Consent appears correctly on simulator and physical device UserDefaults resets hasSeenConsent to false on every launch The file compiles without errors DerivedData has been cleared before archiving Clean build performed before every archive MY QUESTIONS: Could there be a reason the consent screen doesn't appear on the reviewer's device even though it shows correctly on mine? Is there a known issue with SwiftUI conditional views not rendering on certain devices or iOS versions? Has anyone else experienced App Review not seeing UI that works correctly in their own testing? Should I attach screenshots of the consent dialog in the App Review notes or reply? Is there something else Apple expects beyond an in-app consent dialog and privacy policy for third-party AI data sharing? I've been stuck on this for over a month across 8 submissions. Any help or insight would be greatly appreciated.

Hi Apple Developer Community, Since March 16, 2026, our integration with the Apple Ads Campaign Management API (v5) is returning 403 Forbidden on all GET requests to the custom-reports endpoint, while POST requests to create reports continue to work without any issues. Environment API Version: v5 Base URL: https://api.searchads.apple.com/api/v5/ Authentication: OAuth 2.0 (Bearer token — token generation works fine) API User Role: API Account Manager What's broken GET /api/v5/custom-reports/63638557 → 403 Forbidden The response is raw HTML from Apple's gateway, not a JSON API error: <html> <head><title>403 Forbidden</title></head> <body> <center><h1>403 Forbidden</h1></center> <hr><center>Apple</center> </body> </html> This indicates the request is being blocked at the reverse proxy / infrastructure level and never reaches the API application layer. A proper API-level authorization error would return JSON with messageCode and message fields. What still works POST creates report successfully POST /api/v5/custom-reports → 200 OK Response: { "data": { "id": 63638557, "name": "Impression_Share_Report_2026-03-22_daily", "startTime": "2026-02-21", "endTime": "2026-03-22", "granularity": "DAILY", "downloadUri": null, "dimensions": ["appName", "adamId", "countryOrRegion", "searchTerm"], "metrics": ["lowImpressionShare", "highImpressionShare", "rank", "searchPopularity"], "selector": { "conditions": [] }, "state": "QUEUED", "creationTime": "2026-03-23T10:05:25.537", "modificationTime": "2026-03-23T10:05:25.537" }, "pagination": null, "error": null } The report is created and enters QUEUED state with downloadUri: null, which is expected. The normal flow is to poll the GET endpoint until state becomes COMPLETED and downloadUri is populated. But the GET endpoint now returns a 403 at the gateway level, making it impossible to retrieve or download the report. Other endpoints confirmed working POST to standard reporting endpoints (e.g., /api/v5/reports/campaigns/{campaignId}/keywords) → 200 OK All other campaign management GET endpoints (campaigns, ad groups, keywords) → 200 OK OAuth token generation → works fine What we've verified Bearer token is valid and not expired (other endpoints work with the same token) X-AP-Context: orgId= header is present and correct in all requests Accept: application/json and Content-Type: application/json headers are set The reportId (63638557) is a valid ID returned by the successful POST API user has API Account Manager role (not Read-only) No changes were made to our code or credentials — this started failing on March 16 with no code deployment on our side Tested with multiple report IDs (both new and previously created) — all return the same HTML 403 Timeline Before March 16, 2026: Full POST + GET flow for custom reports worked without issues March 16, 2026: GET requests began returning 403. POST requests unaffected. March 18, 2026: We noticed reports about Custom Reports being replaced by Insights Our suspicion We're aware that Apple has introduced the Insights analytics tool as a replacement for Custom Reports. The timing of our 403 errors aligns exactly with this transition. The fact that the 403 is an HTML gateway response (not a JSON API error) suggests the GET route has been deliberately removed from the API gateway configuration. However, we could not find any API changelog, deprecation notice, or migration guide documenting: Whether the custom-reports GET endpoint has been intentionally removed What the replacement API endpoint is for programmatically retrieving report data (especially Impression Share reports) Whether there is a migration timeline or if this is a permanent change Why POST still works if the feature is being deprecated What we need Confirmation: Is the 403 on custom-reports GET intentional due to the Insights migration, or is this a bug/misconfiguration? Migration path: If Custom Reports API is being deprecated, what is the new API endpoint for retrieving Impression Share data programmatically? Is there an Insights API? Timeline: If this is a phased deprecation, when will the POST endpoint also stop working? Documentation: Is there an updated API reference or migration guide? Impact This is a production-breaking issue for our data pipeline. We rely on the POST → GET → download flow to pull Impression Share data (impression share, rank, search popularity by search term and country) for downstream analytics. The standard reporting POST endpoints (/api/v5/reports/campaigns/...) do not support Impression Share metrics, so there is currently no API workaround for this specific data. Any guidance from Apple engineers or anyone in the community experiencing the same issue would be greatly appreciated. Thanks in advance.

We're developing a service that requires webtransport support in the browser. Currently, the only browser that doesn't provide support is the IOS version of Safari. Our current way forward for client use is to flag iphone and ipad as non compliant and recommend either desktop use or android. Is there any ballpark date as to when WebTransport will be included in IOS Safari (- webkit supports webtransport)?

I'm building a SwiftUI app with SwiftData and want to centralize both query logic and related actions in a manager class. For example, let's say I have a reading app where I need to track the currently reading book across multiple views. What I want to achieve: @Observable class ReadingManager { let modelContext: ModelContext // Ideally, I'd love to do this: @Query(filter: #Predicate<Book> { $0.isCurrentlyReading }) var currentBooks: [Book] // ❌ But @Query doesn't work here var currentBook: Book? { currentBooks.first } func startReading(_ book: Book) { // Stop current book if any if let current = currentBook { current.isCurrentlyReading = false } book.isCurrentlyReading = true try? modelContext.save() } func stopReading() { currentBook?.isCurrentlyReading = false try? modelContext.save() } } // Then use it cleanly in any view: struct BookRow: View { @Environment(ReadingManager.self) var manager let book: Book var body: some View { Text(book.title) Button("Start Reading") { manager.startReading(book) } if manager.currentBook == book { Text("Currently Reading") } } } The problem is @Query only works in SwiftUI views. Without the manager, I'd need to duplicate the same query in every view just to call these common actions. Is there a recommended pattern for this? Or should I just accept query duplication across views as the intended SwiftUI/SwiftData approach?

It has been approximately three weeks since we submitted our app for review via App Store Connect, but it remains "In Review" and the review process has not been completed. For this reason, we also requested an expedited app review to the App Review Team last week. Will the review proceed if we simply wait? Is there any way to check the detailed status of this app review?
