Discrepancies in MetricKit and Xcode Organizer Data
We recently integrated MetricKit into our app; however, the 90th percentile data does not seem to match the data in Xcode Organizer. The values reported by MetricKit appear to be higher. Additionally, it looks like data for previous app versions is not being updated in Organizer as adoption of the latest version increases. Has anyone else experienced this issue? Could there be a delay in data updates for older versions in Organizer? Are there any known limitations or best practices for ensuring consistency between MetricKit and Xcode Organizer data? Any guidance would be greatly appreciated.

How to test SignificantChange Permission Ask
I'm developing for compliance with Texas law in the United States. Currently, I'm encountering an issue where I want to test the feature point "when the app undergoes significant changes, a supervised user initiates a request." However, during actual testing, the app pops up an error message: "Can't Ask, An Unknown error occurred." Additionally, I see the following error message in the Xcode Console: "Error Domain=AskToCore.ATMessageComposeValidationError Code=4 'The user is in a region that does not support this type of ask.' UserInfo={NSLocalizedFailureReason=The user must be in a supported region to use this feature., NSLocalizedRecoverySuggestion=Please ensure the user is in an eligible region., NSLocalizedDescription=The user is in a region that does not support this type of ask.}" I am indeed not in the Texas region. I want to conduct full-process testing before the feature is released to the App Store. What should I do? Apart from Sandbox testing (which, in fact, doesn't show any pop-ups either), how can I test under real-world conditions?

Is Apple reading reports in the new Feedback Assistant?
Dear Apple,I'm an iOS developer and provided feedback in the good old online bug tracker for many years.Decent conversations with Apple egnineers often resulted in bug fixes or updated documentation.The fact that my contributions helped to improve the products was rewarding.So I kept adding reports in the new Feedback Assistant app in macOS Catalina.But ever since (September 2019) I never ever got any response on any ticket.1 month ago I even added a report if Apple even read my reports. Again, no response ever since.So my question on this forum: Is Apple actually reading reports in the new Feedback Assistant?This can either be answered by Apple, or by other Developers that hopefully did response feedback from Apple. Or did not.Best regards,Martijn

Developer Mode without PC
My phone's charging port is fried. It only charges wirelessly. Fixing it costs the same as the phone. I currently am having a lot of issues enrolling for apple developer program as well, so I can't use test flight right now. I want to enable developer mode on my phone, but it's never been connected to xcode before, so the option is not available. How do I enable developer mode without being able to connect it to a pc? I have a mac, and both my mac and iphone are on the same apple id. thank you

Will Icon Composer support development of tvOS and visionOS icons?
In the beta of Icon Composer, I see macOS, iOS, and watchOS icons, but there is nothing about visionOS and tvOS. Those icons are particularly hard and it would be great if this app worked for developing icons for all Apple platforms. I tried asking this in a WWDC group lab, but they didn't get to it and suggested posting to the forum.

Developer Disk Image could not be mounted on this device
I have been working on a M1 Mac mini, using my iPad Air M2 running 26.3 iPadOS. Switched to a new M4 Mac mini, went to connect my iPad to run from Xcode and was presented this "The developer disk image could not be mounted on this device." So how can a get an updated DDI? I appreciate any ideas. /Users/robertlawson/Desktop/Screenshot 2026-02-15 at 8.21.50 PM.png

UI Test Cases Failing with Custom Accessibility Labels in SwiftUI
Hello Apple Developer Support, I am writing to seek assistance with an issue we are experiencing in our SwiftUI application concerning UI test cases. Our application uses accessibility labels that differ slightly from the display content to enhance VoiceOver support. However, we have encountered a problem where our UI test cases fail when the accessibility label does not match the actual display content. Currently, we are using accessibility identifiers in our tests, but they only retrieve the accessibility label, leaving us without a method to access the actual display content. This discrepancy is causing our automated tests to fail, as they cannot verify the visual content of the UI elements. We would greatly appreciate any guidance or solutions you could provide to address this issue. Specifically, we are looking for a way to ensure our UI tests can access both the accessibility label and the actual display content for verification purposes. For ex: Problem scenario - setting accessibilityLabel masks access to any displayed content If an accessibilityLabel is set on a UI element, then it seems to be no-longer possible to check/access the displayed content of that element: var body: some View { Text("AAA") .accessibilityIdentifier("textThing") .accessibilityLabel("ZZZ") // Different label from the text which is displayed in UI } // in test... func test_ThingExists() { XCTAssert(app.staticTexts["AAA"].exists) // Fails, cannot find the element XCTAssertEqual(app.staticTexts["ZZZ"].label, "AAA") // Fails - '.label' is the accessibilityLabel, not the displayed content XCTAssertEqual(app.staticTexts["ZZZ"].label, "ZZZ") // Passes, but validates the accessibility content, not the displayed content XCTAssert(app.staticTexts["textThing"].exists) // Passes, but does not check the displayed content XCTAssertEqual(app.staticTexts["textThing"].label, "AAA") // Fails - '.label' is the accessibilityLabel, not the displayed content XCTAssertEqual(app.staticTexts["textThing"].label, "ZZZ") // Passes, but validates the accessibility content, not the displayed content } element.label still only checks the accessibilityLabel. There is not, it seems, an way back to being able to check the content of the Text element directly. Thank you for your attention and support. We look forward to your valuable insights.

Controlling UIDesignRequiresCompatibility via Remote Config
Hello, I am currently in the process of gradually adding support for LiquidGlass to my app. The transition is taking place incrementally, i.e., new screens and minor features are gradually being adapted to the new design and already deployed. Currently, the old design is still active via the feature flag UIDesignRequiresCompatibility, as the existing UI should remain locked for the public app store version until the transition is complete. My challenge is as follows: I would like to work with the new LiquidGlass design during development without having to manually change the UIDesignRequiresCompatibility flag with each deployment. Ideally, I am looking for a solution where: • the new design is only activated for me (e.g., specific account or specific devices) • the old design remains active for all other users • the App Store version can be delivered unchanged So my question is: Is it possible to control UIDesignRequiresCompatibility via remote config or server-side logic in order to activate the new design specifically for certain users or devices? I have observed similar behavior on WhatsApp—two devices with the same app version, but only one shows the new design. This suggests server-side or remote config-based control. Do you have any experience or recommendations on how to implement something like this cleanly? Kind regards Heinz

"Show API Changes" no longer available on Apple Developer Documentation website?
There was a time that Apple Developer Documentation provides a filter to show the changes across versions, at https://developer.apple.com/documentation/technologies , with purple (modified), green (added), and red (deprecated) annotations. I wonder if this feature is completely removed, or is it still hiding somewhere? It is helpful to diff the API changes among versions. Thanks. edit: as pointed out by Rick, here is an archive link to what it used to look like

"Application has not loaded accessibility" timeout followed by silent auto-recovery corrupts framework state on iOS 18
On iOS 18, when XCUITest encounters an "Application has not loaded accessibility" error after the 60 second timeout, it performs an undocumented auto-recovery ("Setting up automation session") instead of halting the test as documented. This leaves the XCUITest framework in a corrupted state, causing subsequent tests in the same session to fail with unexpected behavior. Expected Behavior (per Apple documentation): Any failure in the launch sequence will be reported as a test failure and the test will be halted at that point. Actual Behavior: XCUITest waits 60 seconds for accessibility to load Logs "Application has not loaded accessibility" error Instead of halting, performs "Setting up automation session" (auto-recovery) Test continues with corrupted framework state Subsequent tests in the same session fail with phantom element queries Steps Run XCUITest suite on a real iOS 18 device Have an app with moderately heavy initialization (e.g., synchronous network operations during bootstrap) Observe intermittent "accessibility not loaded" errors When error occurs, subsequent tests fail with unexpected behavior Test Logs Evidence First test (accessibility failure + recovery): t = 11.11s Wait for accessibility to load t = 71.14s Capturing diagnostic spindump t = 76.24s Assertion Failure: Application 'com.example.app' has not loaded accessibility t = 76.26s Setting up automation session ← Undocumented recovery t = 77.29s Tear Down Second test (corrupted state): t = 35.01s Tap "signin-button" t = 35.55s Waiting for "bannerButtonStackFirstItem" ← Query NOT in test code! t = 40.58s Assertion Failure: Failed to find element The second test executes element queries that do not exist in its source code, indicating leaked/corrupted state from the previous test's failed recovery. Note: The tearDown() method terminates the app but cannot reset the internal state of the XCUITest framework itself, so corruption persists across tests. We are observing this behavior consistently on iOS 18 real devices. We would like to know: Is this a known issue with XCUITest on iOS 18? Is anyone experiencing similar "accessibility not loaded" failures followed by auto-recovery? Is the "Setting up automation session" recovery behavior intentional or a bug? Is there a recommended workaround to prevent framework state corruption between tests?

Check whether app is built in debug or release mode
Currently, if as a library author you are shipping dependencies as code, you can use the #if DEBUG preprocessor check to execute logic based on whether app is being built for Debug or Release. My concern is more about the approach that should be taken when distributing frameworks/xcframeworks. One approach I am thinking of using is checking the presence of {CFBundleName}.debug.dylib in the main bundle. Is this approach reliable? Do you suggest any other approach?

iOS 26 Download Link is Broken
I'm trying to download the iOS 26 restore image for my iPhone 14 Pro Max, which is my test device. However, when I attempted to install it directly via the over-the-air (OTA) update, the iPhone rebooted to the iOS 26 "Welcome" screen, but with no touch functionality—the screen was completely unresponsive. I restored the device back to iOS 18.5 and tried the OTA update again, but once more, the touch screen stopped working upon completion. Now, I am trying to download the iOS 26 restore image from the official developer page (https://developer.apple.com/download/#ios-restore-images-ipad-new) to install it manually using my Mac. However, I've run into a problem with the download links: The link for the iPhone 14 Pro Max (iOS 26) restore image actually downloads the iPhone 14 Pro (iOS 18.5) image. Conversely, the link for the iPhone 14 Pro seems to provide the correct iPhone 14 Pro Max (iOS 26) image. The issue is that when I try to restore my iPhone using this seemingly correct file, I receive an error that the firmware file is not valid or compatible. I suspect it's not being properly signed by Apple for my device during the restore process. Does anyone have the correct, official download link for the iOS 26 restore image for the iPhone 14 Pro Max? How can I fix these errors?

On Demand Resources as Legacy Technology
I read on this documentation : https://developer.apple.com/help/app-store-connect/reference/app-uploads/on-demand-resources-size-limits that On Demand Resources a legacy technology. Does this mean ODR will be deprecated? If so, when will it officially take effect? Our application is planning to use it, so we need more information to support our decision.

Is the new iPadOS/macOS 26 help icon available in SF Symbols?
Under macOS 26 and iPadOS, the Help menu in many cases has a menu item for "App Help". This item has the following icon: I need to use this in my own app. I am unable to find this icon in SF Symbols 7 beta. I've scanned all of the icons under "What's New". I've searched for "help", "light", and "bulb" and this icon does not appear. Does anyone know if it's even a new SF Symbol? Or does anyone know of a way to use this icon?
