Overview

I'm using one UITabBarController which leads to 6 NavigationController. Therefore the user will get 4 icons displayed and one icon with three points to see the rest of the Navigation Controller. If the user now tries to edit the list and moves one item from the hidden area towards the TabBar at the bottom, the App crashes with the error: Exception NSException * "Can't add self as subview" 0x0000600000d16040 I can see this effect at least on both my apps. If the same compilation is run on a older iOS version, there is no crash. Is there anything I have to take care of the configuration of the TabBar, when it comes to iOS26?

NSWindow objects with custom styleMask configurations seem to behave erratically in macOS Tahoe 26.3 RC. For example an NSWindow is not resizable after issuing .styleMask.remove(.titled) or some NSWindow-s become totally unresponsive (the NSWindow becomes transparent to mouse events) with custom styleMask-s. This is a radical change compared to how all previous macOS versions or the 26.3 beta3 worked and seriously affects apps that might use custom NSWindows - this includes some system utilities, OSD/HUD apps etc, actually breaking some apps. Such fundamental compatibility altering changes should not be introduced in an RC stage (if this is intentional and not a bug) imho.

When I use the .zoom transition in a navigation stack, I get a glitch when interrupting the animation by swiping back before it completes. When doing this, the source view disappears. I can still tap it to trigger the navigation again, but its not visible on screen. This seems to be a regression in iOS 26, as it works as expected when testing on iOS 18. Has someone else seen this issue and found a workaround? Is it possible to disable interrupting the transition? Filed a feedback on the issue FB19601591 Screen recording: https://share.icloud.com/photos/04cio3fEcbR6u64PAgxuS2CLQ Example code @State var showDetail = false @Namespace var namespace var body: some View { NavigationStack { ScrollView { showDetailButton } .navigationTitle("Title") .navigationBarTitleDisplayMode(.inline) .navigationDestination(isPresented: $showDetail) { Text("Detail") .navigationTransition(.zoom(sourceID: "zoom", in: namespace)) } } } var showDetailButton: some View { Button { showDetail = true } label: { Text("Show detail") .padding() .background(.green) .matchedTransitionSource(id: "zoom", in: namespace) } } }

I have been able to train an adapter on Google's Colaboratory. I am able to start a LanguageModelSession and load it with my adapter. The problem is that after one simple prompt, the context window is 90% full. If I start the session without the adapter, the same simple prompt consumes only 1% of the context window. Has anyone encountered this? I asked Claude AI and it seems to think that my training script needs adjusting. Grok on the other hand is (wrongly, I tried) convinced that I just need to tweak some parameters of LanguageModelSession or SystemLanguageModel. Thanks for any tips.

I applied for the Apple Developer Program on Jan 29th, but my enrollment is still pending with no updates. This delay is really affecting my project timeline since I need to start my app soon, and I can’t move forward without my account being approved. I’ve already reached out to Apple Developer Support, but I haven’t gotten any clear response on when it will be completed. tried even calling the support line but they couldn't help with developer accounts. Has anyone else experienced similar delays? If so, how long did it take for your account to get approved? Would appreciate any advice or insights! Thanks in advance.

I am currently trying to get my app ready for full external keyboard support, while testing I found an issue with the native DatePicker. Whenever I enter the DatePicker with an external keyboard it only jumps to the time picker and I am not able to move away from it. Arrow keys don't work, tab and control + tab only move me to the toolbar and back. This is how they look like private var datePicker: some View { DatePicker( "", selection: date, in: minDate..., displayedComponents: [.date] ) .fixedSize() .accessibilityIdentifier("\(datePickerLabel).DatePicker") } private var timePicker: some View { DatePicker( "", selection: date, in: minDate..., displayedComponents: [.hourAndMinute] ) .fixedSize() .accessibilityIdentifier("\(datePickerLabel).TimePicker") } private var datePickerLabelView: some View { Text(datePickerLabel.localizedString) .accessibilityIdentifier(datePickerLabel) } And we implement it like this in the view: HStack { datePickerLabelView Spacer() datePicker timePicker } Does anyone know how to fix this behavior? Is it our fault or is it the system? The issue comes up both in iOS 18 and 26.

Hello, I am an individual developer working on a macOS application using SwiftUI and RealityKit. I would like to understand the feasibility of face-related tracking on macOS when using an external USB camera, compared to iOS/iPadOS. Specifically: • Does macOS provide an ARKit Face Tracking–equivalent API (e.g., real-time facial expressions, gaze direction, depth)? • If not, is it common to rely on Vision / AVFoundation as alternatives for: • Facial expression coefficients • Gaze estimation • Depth approximation • In an environment without dedicated sensors such as TrueDepth, is it correct to assume that accurate depth data and high-fidelity blend shape extraction are realistically difficult? Any clarification on official limitations, recommended alternatives, or relevant documentation would be greatly appreciated. Thank you.

I've worked through Apple's dice demo for SwiftUI, so far so good. I've got a single Die view with a button to "roll" the die. This works perfectly using the code below: struct DieView: View { init(dieType: DieType) { self.dieValue = Int.random(in: 1...dieType.rawValue) self.dieType = dieType } @State private var dieValue: Int @State private var dieType: DieType var body: some View { VStack { if self.dieType == DieType.D6 { Image(systemName: "die.face.\(dieValue)") .resizable() .frame(width: 100, height: 100) .padding() } else {//self.dieType == DieType.D12{ Text("\(self.dieValue)") .font(.largeTitle) } Button("Roll"){ withAnimation{ dieValue = Int.random(in: 1...dieType.rawValue) } } .buttonStyle(.bordered) } Spacer() } } Now I want to do a DiceSetView with an arbitrary number of dice. I've got the UI working with the following; struct DiceSetView: View { @State private var totalScore: Int = 0 var body: some View { ScrollView(.horizontal) { HStack{ DieView(dieType: DieType.D6) DieView(dieType: DieType.D6) DieView(dieType: DieType.D6) } } HStack{ Button("Roll All"){} .buttonStyle(.bordered) Text("Score \(totalScore)") .font(.callout) } Spacer() } } Where I'm struggling is how to get the total of all the dice in a set and to roll all the dice in a set on a button click. I can't iterate through the dice, and just "click" the buttons in the child views from their parents, and I can't think how it should be structured to achieve this (I'm new to this style of programming!) - can anyone point me in the right direction for how to achieve what I want? I realise that I'm probably missing something fundamentally conceptual here....

I had a free developer account and now have a paid account. I can now install unlimited number of apps on my personal devices. I want to install more than 3 apps on a device of a family member. The device of this member has been registered under Certificates, Identifiers & Profiles. When I try to install apps with xCode on this family device I still get the message that I reached the limit of 3 apps (free account). By signing & capabilities I use the paid account as team. I have deleted all the apps on that device where installed with the free account, restarted the device and restarted xcode but the problem still exists.

I recently found out that my System Storage is at about 200GB. I checked my XCode and found these "ohter installed platforms" (screenshot1). I can delete them there but as soon as I restart my computer, they will show up again. I found the folder /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime which uses 75GB and Im pretty sure that these simulators are the ones in XCode. This folder doesnt change a bit when I delete the simulators in Xcode. I cant delete the folder because of permissions... anyone an idea? Btw: 200gb systemdata of 500gb seems pretty miserable. Kind regards

Hi all, I was wondering if someone could provide more information about the Digital Services Act review process. I haven’t been able to find any details online, and I haven’t received a response to my support requests (it has been 9 days so far). I submitted the requested Digital Services Act information on February 27, but I haven’t received any update or automated confirmation email. The request is still visible under business agreements in my Apple Store Connect account. Does anyone know how long this review typically takes? Or whether I should contact support through a different channel? Thank you in advance!

In iOS 18, when a contact with multiple phone numbers called, the system clearly indicated which specific number was used—often by highlighting it in red for missed calls or tagging it as 'recent.' However, in iOS 26, this distinction is missing, and there is no way to determine which of the contact's numbers the call originated from.

I'm sure this is a basic question, but I'm new to this style of development, so thought Id ask... I've worked through Apple's dice roller demo, so far so good - I'm using the code below to render and roll a single die; struct DieView: View { init(dieType: DieType) { self.dieValue = Int.random(in: 1...dieType.rawValue) self.dieType = dieType } @State private var dieValue: Int @State private var dieType: DieType var body: some View { VStack { if self.dieType == DieType.D6 { Image(systemName: "die.face.\(dieValue)") .resizable() .frame(width: 100, height: 100) .padding() } else { Text("\(self.dieValue)") .font(.largeTitle) } } Button("Roll"){ withAnimation{ dieValue = Int.random(in: 1...dieType.rawValue) } } .buttonStyle(.bordered) Spacer() } } Again, so far so good - works as I'd expect. I can now also add multiple DieViews to a DiceSetView and they display as I'd expect. Where I'm stuck is in the DiceSetView, I want to both determine the total score across the dice, and also offer the ability to Roll All the dice in a set. (Ultimately I want another level above the set, so I'll be looking to roll all dice in all sets) I can't simply call a func / method on the child view (i.e. iterate through them and sum their values, and roll each), I suspect I need to change how it's all structured, but not sure where to go from here... Can anyone point me in the right direction?

Hello, we are using DeviceCheck – App Attest in a production iOS app. The integration has been live for some time and works correctly for most users, but a small subset of users encounter non-deterministic failures that we are unable to reproduce internally. Environment iOS 14+ Real devices only (no simulator) App Attest capability enabled Correct App ID, Team ID and App Attest entitlement Production environment Relevant code let service = DCAppAttestService.shared service.generateKey { keyId, error in // key generation } service.attestKey(keyId, clientDataHash: hash) { attestation, error in // ERROR: com.apple.devicecheck.error 3 / 4 } service.generateAssertion(keyId, clientDataHash: clientDataHash) { assertion, error in // ERROR: com.apple.devicecheck.error 3 / 4 } For some users we intermittently receive: com.apple.devicecheck.error error 3 com.apple.devicecheck.error error 4 Characteristics: appears random affects only some users/devices sometimes resolves after time or reinstall not reproducible on our test devices NSError contains no additional diagnostic info Some questions: What is the official meaning of App Attest errors 3 and 4? Are these errors related to key state, device conditions, throttling, or transient App Attest service issues? Is there any recommended way to debug or gain more insight when this happens in production? Any guidance would be greatly appreciated, as this impacts real users and is difficult to diagnose. Thank you.

I've recently updated one of our CI mac mini's to Sequoia in preparation for the transition to Tahoe later this year. Most things seemed to work just fine, however I see this dialog whenever the UI Tests try to run. This application BoostBrowerUITest-Runner is auto-generated by Xcode to launch your application and then run your UI Tests. We do not have any control over it, which is why this is most surprising. I've checked the codesigning identity with codesign -d -vvvv as well as looked at it's Info.plist and indeed the usage descriptions for everything are present (again, this is autogenerated, so I'm not surprised, but just wanted to confirm the string from the dialog was coming from this app) <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>BuildMachineOSBuild</key> <string>22A380021</string> <key>CFBundleAllowMixedLocalizations</key> <true/> <key>CFBundleDevelopmentRegion</key> <string>en</string> <key>CFBundleExecutable</key> <string>BoostBrowserUITests-Runner</string> <key>CFBundleIdentifier</key> <string>company.thebrowser.Browser2UITests.xctrunner</string> <key>CFBundleInfoDictionaryVersion</key> <string>6.0</string> <key>CFBundleName</key> <string>BoostBrowserUITests-Runner</string> <key>CFBundlePackageType</key> <string>APPL</string> <key>CFBundleShortVersionString</key> <string>1.0</string> <key>CFBundleSignature</key> <string>????</string> <key>CFBundleSupportedPlatforms</key> <array> <string>MacOSX</string> </array> <key>CFBundleVersion</key> <string>1</string> <key>DTCompiler</key> <string>com.apple.compilers.llvm.clang.1_0</string> <key>DTPlatformBuild</key> <string>24A324</string> <key>DTPlatformName</key> <string>macosx</string> <key>DTPlatformVersion</key> <string>15.0</string> <key>DTSDKBuild</key> <string>24A324</string> <key>DTSDKName</key> <string>macosx15.0.internal</string> <key>DTXcode</key> <string>1620</string> <key>DTXcodeBuild</key> <string>16C5031c</string> <key>LSBackgroundOnly</key> <true/> <key>LSMinimumSystemVersion</key> <string>13.0</string> <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict> <key>NSAppleEventsUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSBluetoothAlwaysUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSCalendarsUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSCameraUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSContactsUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSDesktopFolderUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSDocumentsFolderUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSDownloadsFolderUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSFileProviderDomainUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSFileProviderPresenceUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSLocalNetworkUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSLocationUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSMicrophoneUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSMotionUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSNetworkVolumesUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSPhotoLibraryUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSRemindersUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSRemovableVolumesUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSSpeechRecognitionUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSSystemAdministrationUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>NSSystemExtensionUsageDescription</key> <string>Access is necessary for automated testing.</string> <key>OSBundleUsageDescription</key> <string>Access is necessary for automated testing.</string> </dict> </plist> Additionally, spctl --assess --type execute BoostBrowserUITests-Runner.app return an exit code of 0 so I assume that means it can launch just fine, and applications are allowed to be run from "anywhere" in System Settings. I've found the XCUIProtectedResource.localNetwork value, but it seems to only be accessible on iOS for some reason (FB17829325). I'm trying to figure out why this is happening on this machine so I can either fix our code or fix the machine. I have an Apple script that will allow it, but it's fiddly and I'd prefer to fix this the correct way either with the machine or with fixing our testing code.

I am just starting to learn SpriteKit and I'm having trouble selecting a scene to preview an action in the actions editor. I created a new macOS Game project (Language: Swift, Game Technology: SpriteKit). When I open the generated 'Actions.sks' file, I see the message "No Preview Scene Selected" in the editor. I see the 'GameScene.sks' scene listed in the "Select..." control in the lower right, but it is greyed out. I'm not able to figure out how to select a scene to preview the action. I'm running Xcode 26.2 on macOS 15. Thanks very much for the help.

I double-click it, and it doesn't install. I drag it to the provisioning profile folder, and it gets deleted immediately. It's an Apple Developer problem. I've already wiped my Mac clean twice and reinstalled everything, and I'm still having this problem.

Hello, I've just been unfortunate enough to discover a critical issue. I have two apps using Asset Packs, and I believe both apps had an Asset Pack with the same identifier. In App Store Connect for App B, I archived this Asset Pack. However, the Asset Pack has been archived for both Apps. This shouldn't happen.
