Overview

Hi, After enabling the new Enhanced Security capability in Xcode 26, I’m seeing install failures on devices running < iOS 26. Deployment target: iOS 15.0 Capability: Enhanced Security (added via Signing & Capabilities tab) Building to iOS 18 device error - Unable to Install ...Please ensure sure that your app is signed by a valid provisioning profile. It works fine on iOS 26 devices. I’d like to confirm Apple’s intent here: Is this capability formally supported only on iOS 26 and later, and therefore incompatible with earlier OS versions? Or should older systems ignore the entitlement, meaning this behavior might be a bug?

I've followed the setup process to get Apple Hosted Background Assets configured for my project. (https://developer.apple.com/documentation/backgroundassets/downloading-apple-hosted-asset-packs) But when I build and run the app I get the following error... BackgroundAssets/AssetPackManager.swift:174: Fatal error: The process lacks a team ID. I've checked the Signing->Team for both targets and they both have my Team associated. Any help or advice would be appreciated...

Environment: Xcode 26 iOS 26 Also tested on iOS 18 (working correctly) Description: I'm experiencing a behavior change with URL(fileURLWithPath:) when the filename starts with a tilde (~) character. On iOS 18, passing a filename like ~MyFile.txt to URL(fileURLWithPath:) treats the tilde as a literal character. However, on iOS 26, the same code resolves the tilde as the home directory, resulting in unexpected output. Minimal Example: let filename = "~MyFile.txt" let url = URL(fileURLWithPath: filename) print(url.lastPathComponent) Expected Result (iOS 18): ~MyFile.txt Actual Result (iOS 26): 924AF0C4-C3CD-417A-9D5F-733FBB8FCF29 The tilde is being resolved to the app's container directory, and lastPathComponent returns the container UUID instead of the filename. Questions: 1. Is this an intentional behavior change in iOS 26? 2. Is there documentation about this change? 3. What is the recommended approach for extracting filename components when the filename may contain special characters like ~? Workaround: Using NSString.lastPathComponent works correctly on both iOS versions: let filename = "~MyFile.txt" let result = (filename as NSString).lastPathComponent // Returns: "~MyFile.txt" ✅ Is this the recommended approach going forward?

These have been stuck in progress for a long time. Usually this process is fairly quick for this app: id: 92caae7f-1796-4928-bb35-72f5f2667786 id: 3645e93f-a8ac-4826-8a4a-690f980dde8e id: 3645e93f-a8ac-4826-8a4a-690f980dde8e What can be done, it is holding back deployments :(

For testing permission response we can use the sandbox account However, when testing permission requests using the AskCenter API, none of the ask API works for me in xcode 26.2 rc and iOS 26.2 rc. For SignificantAppUpdateTopic, I got errors like "The user is in a region that does not support this type of ask" in the console log, but I've already set my billing address to Texas. For CommunicationTopic, the console shows several XPC-related errors, and I’m not sure which of them are relevant. Both of them show an alert view of "Can't ask, An unknown error occurred" Can someone help to guide us how to test the request flow? Thanks

I’m blocked debugging a watchOS app on a physical Apple Watch. The iPhone connects to Xcode normally (wired), but the Watch either fails to connect with a tunnel timeout or disappears entirely from Xcode after I unpaired it inside Devices & Simulators. Environment Mac: macOS 26.x (Apple Silicon Mac) Xcode: 26.2 iPhone: iOS 26.1 Apple Watch Ultra: watchOS 26.2 (build 23S303) Connection: iPhone connected to Mac via USB (trusted). Watch paired to iPhone and working normally in the Watch app. Issue A (when Watch is visible in Xcode) In Xcode → Window → Devices and Simulators, the Watch shows up but is not usable and fails to connect. Error: “Previous preparation error: A connection to this device could not be established.” “Timed out while attempting to establish tunnel using negotiated network parameters.” In some attempts the Watch shows “Capacity: Unknown” / limited details, and then fails during preparation. Issue B (after unpairing Watch in Xcode only) I unpaired/removed the Watch in Xcode (Devices & Simulators). I did not unpair the Watch from the iPhone. Now: iPhone appears in Xcode and works normally for builds. Watch is still paired to the iPhone and works normally. Watch no longer appears anywhere in Xcode Devices & Simulators (no paired watch section, no watch run destination). What I’ve tried Reboots of Mac, iPhone, Watch (multiple times) Watch unlocked, awake; iPhone unlocked and close to Watch Verified Watch is paired and connected in iPhone Watch app Developer Mode enabled on iPhone and Watch Wi-Fi and Bluetooth ON (Mac/iPhone/Watch), tried toggling both Tried on home Wi-Fi and also with iPhone hotspot (same result) Resetting trust prompts / reconnecting iPhone via USB, re-trusting Mac Apple Watch: “Clear Trusted Computers” Xcode: removing/re-adding devices; clearing derived data; restarting Xcode Watch Developer networking test: Responsiveness = Medium (430 RPM) Questions 1. Is this a known issue/regression with Xcode 26.2 + watchOS 26.2 tunneling (CoreDevice / devicectl)? 2. Is there an Apple-supported way to force Xcode to re-discover a paired Watch after it was removed from Xcode Devices & Simulators (without unpairing the Watch from the iPhone)? 3. Any recommended logs or diagnostic steps I should collect (Console logs, sysdiagnose, specific Xcode/CoreDevice logs) to include in a Feedback report? If helpful, I can provide the full error text from Xcode’s Devices window and any logs you recommend. Thank you in advance,

Hey, so I wanted to pull from the Github project repository and XCode asked me login again. Forgot my password so I tried a wrong one and now it keeps asking for my Username and Access token, when I actually just want to login with my password. Doesn't let me choose between the too, not even when adding the account through preferences. Anyone know how to just login with password and the reason for this -pardon me- absolutely idiotic choice of not letting the user choose?

Hi all, I’m an Admin user in an Apple Developer Program (Organization) team, but I’m unable to access Certificates, Identifiers & Profiles (CIP) on developer.apple.com. I’d like to understand what permission is missing and where it should be enabled. Context Program type: Apple Developer Program (Organization) My role in App Store Connect: Admin I can access App Store Connect normally, but CIP resources on developer.apple.com are blocked. The Account Holder can access CIP normally. What I see (Problem) In the Apple Developer portal → Certificates, Identifiers & Profiles, I get: “Access Unavailable — You currently don't have access to this membership resource. Contact your team's Account Holder or an Admin.” In Xcode → Settings → Accounts → Team, the “Certificates, Identifiers, & Profiles” section shows a red error indicator and doesn’t load. Only my account is affected; the Account Holder is not. What we’ve tried / confirmed Membership is active (renewal date is valid) Signed out/in of Xcode and re-added my Apple ID Confirmed selecting the correct Organization team in Xcode / Developer portal Account Holder confirmed they can access CIP Questions For an Organization team, what exact permission(s) are required for a member to access Certificates, Identifiers & Profiles? Where is this access controlled — App Store Connect → Users and Access vs developer.apple.com → People? If Admin in App Store Connect is not sufficient, what additional role/setting is needed to grant CIP access?

QuickLookAR shares the actual USDZ model instead of the original website URL — critical copyright and data leak issue on iOS 26 Since iOS 26, QuickLookAR (or ARQuickLookPreviewItem) no longer preserves the original web URL when sharing a model. Instead of sending the link to the hosted file, the system directly shares the actual USDZ model file with the recipient. This is a critical regression and a severe breach of intellectual property protection, as it exposes proprietary 3D models that must never be distributed outside of the controlled web environment. In earlier iOS versions (tested up to iOS 18), QuickLookAR correctly handled sharing — the share sheet would send the website link where the model is hosted, not the file itself. Starting with iOS 26, this behavior has changed and completely breaks the intended secure flow for AR experiences. Our project relies on allowing users to view models in AR via QuickLook, without ever transferring the underlying 3D assets. Now, the share operation forces full file sharing, giving end users unrestricted access to the model file, which can be copied, rehosted, or reverse-engineered. This issue critically affects production environments and prevents us from deploying our AR-based solutions. Implement a standard QuickLookAR preview with a USDZ file hosted on your web server (e.g., via ARQuickLookPreviewItem). 2. Open the AR view on iOS 26. 3. Tap the Share icon from QuickLookAR. 4. Send via any messenger (Telegram, WhatsApp, etc.). 5. Observe that the actual .usdz model is sent instead of the original website URL. ⸻ Expected behavior: QuickLookAR should share only the original URL (as in iOS 17–18), not the file itself. This ensures that intellectual property and licensed 3D models remain protected and controlled by the content owner. ⸻ Actual behavior: QuickLookAR shares the entire USDZ file, leaking the model content outside of the intended environment. ⸻ Impact: • Violation of copyright and confidential data policies • Loss of control over proprietary 3D assets • Breaking change for all existing web-based AR integrations • Critical blocker for AR production deployment ⸻ Environment: • iOS 26.0 and 26.1 (tested on iPhone 14, iPhone 15) • Safari + QuickLookAR integration • Works correctly on iOS 17 / iOS 18 ⸻ Notes: This regression appears to have been introduced in the latest iOS 26 system handling of QuickLookAR sharing. Please escalate this issue to the ARKit / QuickLook engineering team as it directly affects compliance, IP protection, and usability of AR features across production applications. Additional Notes / Verification: Please test this behavior yourself using the CheckAR test model on my website: https://admixreality.com/ios26/ • If the login page appears, click “Check AR” and then “View in Your Space”. • On iOS 18 and earlier, sharing correctly sends the website URL. • On iOS 26, sharing sends the actual USDZ model file. This clearly demonstrates the regression and the security/IP issue.

I’m currently developing an application using WKWebView. After updating to iOS 26.2 Developer Beta, the following Web API started returning false: isUserVerifyingPlatformAuthenticatorAvailable MDN: https://developer.mozilla.org/ja/docs/Web/API/PublicKeyCredential/isUserVerifyingPlatformAuthenticatorAvailable_static This issue did not occur on iOS 26.1 — it only happens on the beta version. Has anyone else encountered this problem or is aware of any related changes? OS: iOS 26.2 beta 3 (23C5044b)

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.

Hey all, I am a first time publisher navigating the App Review process. I want to publish a watchOS only app, but keep getting this feedback: Regarding 4.0, Apple Watch app icon's background color is still black. Based on our investigation, you have included plain black icons. To resolve this issue, it would be appropriate to modify your app's Apple Watch app icon to include a lighter background color to ensure that it is recognizable and appears circular on Apple Watch. I set the following configs: Project -> Targets -> Apple Watch App -> App Icons & Launch Screen -> App Icon set to my Icon Composer file. Checked App Icons Source. I was able to install my build through TestFlight and successfully install on my watch, and the App Icon displays properly there. I also saw a recent Reddit post from another developer facing the same issue. I can't link that post, but will share this post with the OP. I attached what the reviewer sent me with the rejection.

I'm experiencing a contradictory validation issue with DeviceActivityReportExtension that creates an impossible situation: The Problem: Without NSExtensionPrincipalClass in Info.plist → App Store Connect rejects upload with: "Missing Info.plist values. No values for NSExtensionMainStoryboard or NSExtensionPrincipalClass found" With NSExtensionPrincipalClass → Local install fails with: "defines either an NSExtensionMainStoryboard or NSExtensionPrincipalClass key, which is not allowed for the extension point com.apple.deviceactivityui.report-extension" Setup: Extension point: com.apple.deviceactivityui.report-extension Using SwiftUI with @main attribute and DeviceActivityReportExtension protocol Xcode 16.2, iOS 17.6 deployment target Code structure: @main struct SpoolReport: DeviceActivityReportExtension { var body: some DeviceActivityReportScene { // Report scenes here } } The extension builds and runs perfectly without NSExtensionPrincipalClass, but cannot be uploaded to App Store Connect. Adding the key allows upload but breaks local installation. Is this a known issue? Is there a workaround or correct Info.plist configuration for DeviceActivityReportExtension? Thank you!

I was reading a tutorial for obtaining an Apple Developer ID Installer certificate in order to distribute my .pkg outside the Mac App Store. However in the Certifcates/add page I'm am unable to see the required certificate (Developer ID Installer). Do I need to get some extra permissions to view this option or was it removed/moved to somewhere else?

Hey, I am just about to prepare my app for Swift 6, and facing the issue that UserDefaults is not Sendable. The documentation states that its thread safe, so I am wondering, why is it not marked as Sendable? Was it just forgotten? Is it safe to mark it as nonisolated(unsafe) or @unchecked Sendable?

Hi, I have been recently debugging the BGContinuedProcessingTask API and encountered some of the following issues. I hope you can provide some answers: First, let me explain my understanding of this API. I believe its purpose is to allow an app to trigger tasks that can be represented with progress indicators and require a certain amount of time to complete. After entering the background, these tasks can continue to be completed through the BGContinuedProcessingTask, preventing the system from terminating them before they are finished. In the launchHandler of the registration process, we only need to do a few things: Determine whether the actual business processing is still ongoing. Update the progress, title, and subtitle. Handle the expirationHandler. Set the task as completed. Here are some issues I encountered during my debugging process: After I called register and submit, the BGContinuedProcessingTask could not be triggered. The return values from my API calls were all normal. I tried different device models, and some could trigger the task normally, such as the 15 Pro Max and 12 Pro Max. However, there were also some models, such as the 17 Pro, 15 Pro, and 15, that could not trigger the task properly. Moreover, there was no additional error information to help locate the issue. The background task failed unexpectedly, but my app was still running normally. As I mentioned above, my launchHandler only retrieves the actual business status and updates it. If a background task fails unexpectedly while the app is still running normally, it can mislead users and degrade the user experience of the app. Others have also mentioned the issue of inconsistent behavior on devices that do not support Dynamic Island. On devices that support Dynamic Island, when a task is triggered in the foreground, the app does not immediately display a pop-up notification within the app. However, on devices that do not support Dynamic Island, the app directly displays a pop-up notification within the app, and this notification does not disappear when switching between different screens within the same app. The user needs to actively swipe up to dismiss it. I think this experience is too intrusive for users. I would like to know whether this will be maintained in the future or if there is a plan to fix it. On devices that do not support Dynamic Island, using the beta version 26.1 of the system, if the system is in dark mode but the app triggers a business interface in white, the pop-up notification will have the same color as the current page, making it difficult to read the content inside the pop-up. Users can actively stop background tasks by using the stop button, or the system can also stop tasks automatically when resources are insufficient or when a task is abnormal. However, according to the current API, all these actions are triggered through the expirationHandler. Currently, there is no way to distinguish whether the task was stopped by the user, by the system due to resource insufficiency, or due to an abnormal task. I would like to know whether there will be more information provided in the future to help distinguish these different scenarios. I believe that the user experience issues mentioned in points 2 and 3 are the most important. Please help to answer the questions and concerns above. Thank you!

When you use .navigationTransition(.zoom(sourceID: "placeholder", in: placehoder)) for navigation animation, going back using the swipe gesture is still very buggy on IOS26. I know it has been mentioned in other places like here: https://developer.apple.com/forums/thread/796805?answerId=856846022#856846022 but nothing seems to have been done to fix this issue. Here is a video showing the bug comparing when the back button is used vs swipe to go back: https://imgur.com/a/JgEusRH I wish there was a way to at least disable the swipe back gesture until this bug is fixed.

I have the following view hierarchy in my app: [UINavigationController] -> [MainViewController] -> [MyTabBarController] -> [DashboardViewController] In my MainViewController I have a button that pushes the MyTabBarController onto the navigation controllers stack. In the tab bar controller I only have one tab in this example showing the DashboardViewController. That all works fine, and when I tap the back button on MyTabBarController, everything works fine and the MainViewController is shown again. The UI works exactly how I want it, but when I load up the 'Debug Memory Graph' view, I can see that my DashboardViewController is still in memory and it seems the UITab has a reference to it. The MyTabBarController is NOT in memory anymore. MyTabBarController is very simple: class MyTabBarController: UITabBarController { override func viewDidLoad() { super.viewDidLoad() self.mode = .tabSidebar var allTabs:[UITab] = [] let mainTab = UITab(title: "Dashboard", image: UIImage(systemName: "chart.pie"), identifier: "dashboard", viewControllerProvider: { _ in return UINavigationController(rootViewController: DashboardViewController()) }) allTabs.append(mainTab) setTabs(allTabs, animated: false) } } And the DashboardViewController is empty: class DashboardViewController: UIViewController { } The only reason I created as a seperate class in this example is so I can easily see if it's visible in the memory debug view. I have uploaded the simple sample app to GitHub: https://github.com/fwaddle/TabbarMemoryLeakCheck Anyone have any suggestions? Here is a screen grab of the memory debug view showing the UITab having a reference to the DashboardViewController even though MyTabBarController has been dealloc'd:

I am trying to Build server for testing on Linux(Alma linux 9 VM) NAME="AlmaLinux" VERSION="9.7 (Moss Jungle Cat)" ID="almalinux" ID_LIKE="rhel centos fedora" VERSION_ID="9.7" PLATFORM_ID="platform:el9" PRETTY_NAME="AlmaLinux 9.7 (Moss Jungle Cat)" ANSI_COLOR="0;34" [azuki@AlmaDevVM ~]$ uname -m x86_64 I have tried the following steps: Before starting, ensured that Swift 6 installed.

I'm trying to train a text classifier model in Create ML. The Create ML app/framework offers five algorithms. I can successfully train the model with all of the algorithms except the BERT transfer learning option. When I select this algorithm, Create ML simply stops the training process immediately after the initial feature extraction phase (with no reported error). What I've tried: I tried simplifying the dataset to just a few classes and short examples in case there was a problem with the data. I tried experimenting with the number of iterations and language/script options. I checked Console.app for logged errors and found the following for the Create ML app: error 10:38:28.385778+0000 Create ML Couldn't read event column - category is invalid. Format string is : <private> error 10:38:30.902724+0000 Create ML Could not encode the entity <private>. Error: <private> I'm not sure if these errors are normal or indicative of a problem. I don't know what it means by the "event" column – I don't have an event column in my data and I don't believe there should be one. These errors are not reported when using the other algorithms. Given that I couldn't get the app to work with BERT, I switched over to the CreateML framework and followed the code samples given in the documentation. (By the way, there's an error in the docs: the line let (trainingData, testingData) = data.stratifiedSplit(on: "text", by: 0.8) should be stratifying on "label", not on "text"). The main chunk of code looks like this: var parameters = MLTextClassifier.ModelParameters( validation: .split(strategy: .automatic), algorithm: .transferLearning(.bertEmbedding, revision: 1), language: .english ) parameters.maxIterations = 100 let sentimentClassifier = try MLTextClassifier( trainingData: trainingData, textColumn: "text", labelColumn: "label", parameters: parameters ) Ultimately I want to train a single multilingual model, and I believe that BERT is the best choice for this. The problem is that there doesn't seem to be a way to choose the multilingual Latin script option in the API. In the Create ML app you can theoretically do this by selecting the Latin script with language set to "Automatic", as recommended in this WWDC video (relevant section starts at around 8:02). But, as far as I can tell, ModelParameters only lets you pick a specific language. I presume the framework must provide some way to do this, since the Create ML app uses the framework under the hood, but I can't see a way to do it. Another possibility is that the Create ML app might be misrepresenting the framework – perhaps selecting a specific language in the app doesn't actually make any difference – for example, maybe all Latin languages actually use the same model under the hood and the language selector is just there to guide people to the right choice (but this is just my speculation). Any help would be much appreciated! If possible, I'd prefer to use the Create ML app if I can get the BERT option to work – is this actually working for anyone? Or failing that, I want to use the framework to train a multilingual Latin model with BERT, so I'm looking for instructions on how to choose that specific option or confirmation that I can just choose .english to get the correct Latin multilingual model. I'm running Xcode 26.2 on Tahoe 21.1 on an M1 Pro MacBook Pro. I have version 6.2 of the Create ML app.
