Can reproduce in SpeakerBox that CallKit doesn't activate audiosession when call finished by remote caller
I can reproduce the bug that CallKit doesn't active audiosession after the outgoing call put on hold because of an incoming call. VoIP calling with CallKit Steps to reproduce: Download SpeakerBox example app from the link above and start it with XCode Start a new outgoing call Call your phone from other phone Hold and Accept the call After a few secs finish the call from the other phone The outgoing call will be still on hold Click on the call and click Toggle Hold The call won't be active again because the audiosession is activated.

How to optimize my app for for a carrier-provided satellite network?
Hello, I am working to integrate the new com.apple.developer.networking.carrier-constrained.app-optimized entitlement in my iOS 26 app so that my app can use a carrier-provided satellite network, and want to confirm my understanding of how to detect and optimize for satellite network conditions. (Ref: https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.developer.networking.carrier-constrained.app-optimized ) My current approach: I plan to set the entitlement to true once my app is optimized for satellite networks. To detect if the device is connected to a satellite network, I intend to use the Network framework’s NWPath properties: isUltraConstrained — I understand this should be set to true when the device is connected to a satellite network. (Ref: https://developer.apple.com/documentation/network/nwpath/isultraconstrained ) linkQuality == .minimal — I believe this will also be set in satellite scenarios, though it may not be exclusive to satellite connections. (Ref: https://developer.apple.com/documentation/network/nwpath/linkquality-swift.enum/minimal ) Questions: Is it correct that isUltraConstrained will reliably indicate a satellite connection? Should I also check for linkQuality == .minimal, or is isUltraConstrained sufficient? Are there any additional APIs or best practices for detecting and optimizing for satellite connectivity that I should be aware of? Thank you for confirming whether my understanding and approach are correct, and for any additional guidance.

Is it possible to use the Matter.xcframework without using the MatterSupport extension for onboarding a device to our ecosystem?
Is it possible to use the Matter.xcframework without the MatterSupport extension for onboarding a Matter device to our own ecosystem(own OTBR and matter controller) for an official App Store release? Currently, we can achieve this in developer mode by adding the Bluetooth Central Matter Client Developer mode profile (as outlined here https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/darwin.md). For an official release, what entitlements or capabilities do we need to request approval from Apple to replace the Bluetooth Central Matter Client Developer mode profile? Thank you for your assistance.

WebView makes website content unaccessible on the top/bottom edges
I'm being faced with an issue when using SwiftUI's WebView on iOS 26. In many websites, the top/bottom content is unaccessible due to being under the app's toolbars. It feels like the WebView doesn't really understand the safe areas where it's being shown, because the content should start right below the navigation bar, and only when the user scrolls down, the content should move under the bar (but it's always reachable if the users scroll back up). Here's a demo of the issue: Here's a 'fix' by ensuring that the content of the WebView never leaves its bounds. But as you can see, it feels out of place on iOS 26 (would be fine on previous OS versions if you had a fully opaque toolbar): Code: struct ContentView: View { var body: some View { NavigationStack { WebView(url: URL(string: "https://apple.com")).toolbar { ToolbarItem(placement: .primaryAction) { Button("Top content covered, unaccessible.") {} } } } } } Does anyone know if there's a way to fix it using some sort of view modifier combination or it's just broken as-is?

Swift Playgrounds macOS repeatedly asks “My App would like to access data from other apps”
Environment: Swift Playgrounds (macOS) SwiftUI App Preview macOS version: 26.2 (25C56) Issue: In Swift Playgrounds on macOS, the app repeatedly shows the system permission dialog: “My App would like to access data from other apps. Keeping app data separate makes it easier to manage your privacy and security.” Steps to Reproduce: Create a new SwiftUI app in Swift Playgrounds. Run the SwiftUI App Preview. When the permission dialog appears, click “Allow”. Expected Result: The permission should be granted once and persist, allowing the preview to continue normally. Actual Result: After clicking “Allow”, the SwiftUI App Preview crashes and restarts. When the preview restarts, the same permission dialog appears again. This repeats indefinitely, creating a loop. Notes: This occurs even when no explicit file system or inter-app data access code is written. The permission choice does not appear to persist between preview restarts. Question: Is this a known limitation of Swift Playgrounds sandboxing or SwiftUI App Preview? Is there an official workaround or recommended approach to avoid this behavior while using Swift Playgrounds?

Guidance on implementing Declared Age Range API in response to Texas SB2420
I've spent the last few days researching the upcoming laws in Texas and other US states, and how these laws will impact on developers around the world. I want to share what I've learned so far with the community and get feedback on my current understanding. This post is not so much focused on a single API, but more of the bigger picture. Background The law essentially mandates that: (1) app store platforms implement age categorization and verification mechanisms, and (2) developers implement logic to listen to age categorization signals provided by the platform and respond accordingly. You can read the law itself here: https://capitol.texas.gov/tlodocs/89R/billtext/html/SB02420S.HTM Most people seem to be interpreting the law as follows: All developers who distribute apps in the USA are effectively required to implement the new APIs (required by Texas, not by Apple). The penalties are heavy, but it's unclear whether developers would actually be pursued and by whom (e.g. would someone seriously pursue an alarm clock app because it could be accessed by a minor?). Putting aside the ethical, privacy, and legal issues (and the damaging precedents this law sets), most people seem to agree that, from a technical perspective, this is a very silly way to implement age blocking (app store collects the info and passes it to dev, dev is responsible for blocking access). It would make way more sense for the platform to block the app directly for affected users (with optional API support for developers who wish to use it). However, I believe the law has specifically mandated that this is how they expect the system to work, so Apple's hands have been tied. Apple has basically complied with their obligations by providing the relevant APIs to developers. Because the law is vague and open-ended, there are a lot of legal and technical uncertainties about what developers actually need to do to be compliant. Understandably, Apple seems reticent to provide any guidance to developers that could be interpreted as legal advice. Apple's docs simply describe what the APIs do with no guidance on what the overall flow is meant to look like or how and when the APIs should actually be used in practice. Americans familiar with the political situation seem to think there's the possibility of an injunction before this law goes into effect, but that looks increasingly unlikely given that it's two weeks away. Developer solutions Many devs seem to be exploring two main workarounds, at least as temporary solutions: (1) Raise your app's rating to 18+. Putting aside the fact that Texas law would effectively be forcing developers to raise their global age rating (resulting in lost revenue that extends far beyond Texas), it remains unclear whether this solution is actually legally compliant, since the law specifically mandates that apps must implement logic to respond to signals from the platform. (2) Geo-block Texas. Again, it remains unclear if this is compliant because geo-blocking is not 100% accurate and it doesn't actually do what the law says you have to do. It also creates issues if you already have users in Texas, and it means performing additional privacy-hostile checks (i.e., detecting the user's location, even users who are not subject to the law). The DeclaredAgeRange API is actually pretty straight-forward to use – although there is still a lack of documentation on certain edge cases and it's difficult to test. In addition, the new APIs are only available in iOS 26.2, so it's unclear what you need to do if you're still supporting < iOS 26.2. Some people are of the opinion that developers can only reasonably respond to the signals that are available, thus pushing responsibility back to the platforms in regards to earlier OS versions. The API provides a bool (AgeRangeService.shared.isEligibleForAgeFeatures), which allows you to determine if the user is someone to whom age checks need to be applied. https://developer.apple.com/documentation/declaredagerange/agerangeservice/iseligibleforagefeatures I'm not 100% sure, but perhaps the simplest action you can take is to check this bool on launch and block access if it's true. In any case, it looks like this API will be very useful because it means we can avoid applying the checks in other jurisdictions and for grandfathered-in users without needing to implement custom geo-tracking code (albeit only in iOS 26.2+). To implement the API, my current thinking is that, on every launch, I should first check the above bool and, if it's true, do the following: (1) get the App Store age rating with let appStoreAgeRating = await AppStore.ageRatingCode ?? 18, (2) request the user's age with let ageRangeResponse = try await AgeRangeService.shared.requestAgeRange(ageGates: appStoreAgeRating), (3) check that the user has agreed to share their age, (4) check that lowerBound >= appStoreAgeRating, and (5) check that the verification method is not one of the self-declared methods. If this procedure fails, I should block access to the app and provide a link to Apple's support page: https://support.apple.com/en-us/122770 I stress, however, that this is just my current idea and there are some edge cases I'm unsure about. Other issues It is possible to do some basic testing of the API, but only using a sandbox App Store account on a physical device. From the Developer section in iOS Settings, you can select from a few different scenarios, like "Texas user aged 14 without parental consent", etc. There's also a whole separate aspect to this law relating to "significant updates". Everyone seems kinda confused about this, but it seems like the general idea is that, if your app's age classification changes in the future, the app should be responsive to that change. My current interpretation is that if I use the AppStore.ageRatingCode as the age gate (as described above) then that should allow me to comply, but I haven't really looked into this aspect of the law yet. There's also another aspect to this law requiring developers to revoke access to the app when requested by the parent. I have not looked into this yet, but as noted above, it doesn't make sense to me why this is the developer's responsibility given that the platforms already provide solid parental controls. Do I need to something else in addition to what I've sketched out above? It goes without saying, of course, that everything above is not legal advice, and I still have some gaps in my understanding. I would really appreciate any feedback on the above, perhaps with recommendations about better ways to approach this.

Inquiry Regarding the Scope of DeclaredAgeRange Acquisition​
We are integrating Apple’s DeclaredAgeRange SDK. To comply with relevant regulatory requirements, our understanding is as follows: The app is only required to obtain the declared age range for users located in Texas. For users outside of Texas, we should not proactively request age range information. Accordingly, we would like to confirm the following: Are we required to present the age range request prompt to all users in the United States? If yes, we are concerned that this may significantly impact the overall user experience. If it is permissible to request age range only for Texas users, how can we reliably determine whether a user is located in Texas on the client side? For example, does Apple provide an API or recommended method for accurately identifying a user’s region (specifically Texas)?

Code Coverage Not Accurate in Xcode 26
Description: I’m noticing that the code coverage metrics in Xcode 26 are not accurate compared to earlier versions. In Xcode 15, the same set of unit tests shows around 38% coverage, but in Xcode 26, even though all the tests are running successfully (for example, the SegmentedUI test cases), the code coverage is displayed as 0%. Has anyone else observed this behavior in Xcode 26? Is there any known issue, workaround, or configuration change required to get the correct coverage report? Environment: Xcode 26 iOS 18 SDK Unit tests running under XCTest Any insights or suggestions would be appreciated.

visionOS – Starting GroupActivity FaceTime Call dismisses Immersive Space
Hello, I am in the process of implementing SharePlay support in my visionOS app. Everything runs fine when I test locally, but when my app is distributed via TestFlight, calling try await activity.activate() shows the SharePlay dialog as usual, but then when I start a new FaceTime call, my ImmersiveSpace gets dismissed. This is only happening when the app is distributed via TestFlight, when I run it locally the ImmersiveSpace stays active as expected. Looking at the console on my Mac I found this log: Invalid initial client settings class: UIApplicationSceneClientSettings; expected class: MRUISharedApplicationSceneClientSettings; bundle ID: com.apple.facetime; scene ID: com.apple.facetime:SFBSystemService-DDA8C751-C0C4-487E-AD85-59EF4E6C6050 Does anyone have an idea how I can fix this? It's driving me nuts and I wasted over a day looking for a workaround but so far been unsuccessful. Thanks!

iOS 26.2 (23C55): DeviceActivity eventDidReachThreshold fires with 0 Screen Time minutes
On iOS 26.2 (23C55), DeviceActivityMonitor.eventDidReachThreshold fires intermittently for a daily schedule (00:00–23:59) even when iOS Screen Time shows 0 minutes for the selected apps that day. This causes premature shielding via ManagedSettings. Environment: iPhone 13 Pro Max, iOS 26.2 (23C55). Event selection: 2 apps. Threshold: 30 minutes. Multiple TestFlight users report the same behavior across various app selections and thresholds. Intermittent (~50% of days); sometimes multiple days in a row. Not observed in testing prior to iOS 26.2. Evidence: sysdiagnose + Screen Time screenshots (with 0 screen time on selected apps) + unified logs show UsageTrackingAgent notifying the extension that “unproductive from activity daily reached its threshold,” followed immediately by ManagedSettings shield being applied (extension reacting to the callback). Filed Feedback Assistant: FB21450954. Questions: Are others seeing this on 26.2? Does it correlate with restarting monitoring at interval boundaries or includesPastActivity settings?

Extreme increase in app storage size after enabling CloudKit
I have a SwiftData flashcard app which I am syncing with CloudKit using NSPersistentCloudKitContainer. While syncing itself is working perfectly, I have noticed a dramatic increase in the app size after enabling sync. Specifically, without CloudKit, 15k flashcards results in the default.store file being about 4.5 MB. With CloudKit, default.store is about 67 MB. I have inspected the store and found that most of this increase is due to the ANSCKRECORDMETADATA table. My question is, does implementing CloudKit normally cause this magnitude of increase in storage? If it doesn’t, is there something in my model, schema, implementation, etc. that could be causing it? Below are two other posts describing a similar issue, but neither with a solution. I replied to the first one about a month ago. I then submitted this to Developer Technical Support, but was asked to post my question in the forums, so here it is. Strange behavior with 100k+ records in NSPersistentCloudKitContainer Huge increase in sqlite file size after adopting CloudKit

iOS 26.1 PHPickerConfiguration.preselectedAssetIdentifiers doesn't select previous pictures in the PHPickerViewController
Hi, I faced with the issue on iOS 26.1 with PHPickerViewController. After first selection I save assetIdentifier of PHPickerResult for images. next time I open the picker I expect to have the images selected based on assetIdentifier Code: var config = PHPickerConfiguration(photoLibrary: .shared()) config.selectionLimit = 10 config.filter = .images config.preselectedAssetIdentifiers = images.compactMap(\.assetID) let picker = PHPickerViewController(configuration: config) picker.delegate = self present(picker, animated: true) But on iOS 26.1 they aren't selected. On lower iOS version all works fine. Does anybody faced with similar issue?

Slow rendering List backed by SwiftData @Query
Hello, I've a question about performance when trying to render lots of items coming from SwiftData via a @Query on a SwiftUI List. Here's my setup: // Item.swift: @Model final class Item: Identifiable { var timestamp: Date var isOptionA: Bool init() { self.timestamp = Date() self.isOptionA = Bool.random() } } // Menu.swift enum Menu: String, CaseIterable, Hashable, Identifiable { var id: String { rawValue } case optionA case optionB case all var predicate: Predicate<Item> { switch self { case .optionA: return #Predicate { $0.isOptionA } case .optionB: return #Predicate { !$0.isOptionA } case .all: return #Predicate { _ in true } } } } // SlowData.swift @main struct SlowDataApp: App { var sharedModelContainer: ModelContainer = { let schema = Schema([Item.self]) let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) return try! ModelContainer(for: schema, configurations: [modelConfiguration]) }() var body: some Scene { WindowGroup { ContentView() } .modelContainer(sharedModelContainer) } } // ContentView.swift struct ContentView: View { @Environment(\.modelContext) private var modelContext @State var selection: Menu? = .optionA var body: some View { NavigationSplitView { List(Menu.allCases, selection: $selection) { menu in Text(menu.rawValue).tag(menu) } } detail: { DemoListView(selectedMenu: $selection) }.onAppear { // Do this just once // (0..<15_000).forEach { index in // let item = Item() // modelContext.insert(item) // } } } } // DemoListView.swift struct DemoListView: View { @Binding var selectedMenu: Menu? @Query private var items: [Item] init(selectedMenu: Binding<Menu?>) { self._selectedMenu = selectedMenu self._items = Query(filter: selectedMenu.wrappedValue?.predicate, sort: \.timestamp) } var body: some View { // Option 1: touching `items` = slow! List(items) { item in Text(item.timestamp.description) } // Option 2: Not touching `items` = fast! // List { // Text("Not accessing `items` here") // } .navigationTitle(selectedMenu?.rawValue ?? "N/A") } } When I use Option 1 on DemoListView, there's a noticeable delay on the navigation. If I use Option 2, there's none. This happens both on Debug builds and Release builds, just FYI because on Xcode 16 Debug builds seem to be slower than expected: https://indieweb.social/@curtclifton/113273571392595819 I've profiled it and the SwiftData fetches seem blazing fast, the Hang occurs when accessing the items property from the List. Is there anything I'm overlooking or it's just as fast as it can be right now?

Accepted Developer Program Agreement on developer.apple.com, but App Store Connect still shows "Agreement Update" warning.
I am the sole Account Holder for my Apple Developer Program account and am encountering an issue where the acceptance of the updated Apple Developer Program License Agreement is not syncing correctly between the two developer portals. Issue Details: Agreement Status on developer.apple.com: I successfully accepted and reviewed the updated agreement at https://developer.apple.com/account. The Agreements section confirms the acceptance date as December 11, 2025 (as seen in the attached image). Status on App Store Connect: Despite this confirmation, when I sign into https://appstoreconnect.apple.com/, I still see the following critical warning: "The Apple Developer Program License Agreement has been updated and needs to be reviewed. In order to update your existing apps and submit new apps, the Account Holder must review and accept the updated agreement by signing in to their account." Impact: This prevents me from performing key tasks, such as creating a new app, which triggers an "Agreement Update" alert that only directs me back to the already-accepted agreement on the Developer website. Troubleshooting Steps Taken: I confirmed I am logged in as the Account Holder. I cleared my browser cache and attempted the process on a fresh browser session. My macOS is fully up to date. I have already contacted Apple Developer Support but have not yet received a reply. Request for Assistance This is blocking my ability to submit and update apps. I am aware that direct phone support is often recommended for these issues, but my country is not listed for phone extension support. Has anyone else experienced this sync delay or found a workaround that resolves the "Agreement Update" alert on App Store Connect when the agreement has been accepted on the Developer website? Any advice on the next immediate steps I should take while waiting for my support ticket to be processed would be greatly appreciated.
