MacOS 15.4 removes rsync —log-file option?
I installed MacOS Sequoia 15.4 and now my backup script no longer works. My script is using rsync in this way: rsync -avz —delete —log-file=“$LOG_FILE” “$SRC_DIR” “$DEST_DIR” This has been working fine for a very long time. After updating to 15.4, this produces the error “rsync: unrecognized action —log-file=/users/admin/logs/backuplog_xxx.log”. The log file path is correct (and hasn’t changed). Interestingly, the man page for rsync no longer shows the —log-file as an option. I know I can use: rsync -avz —delete “$SRC_DIR” “$DEST_DIR” > “$LOG_FILE”` or even rsync -avz —delete “$SRC_DIR” “$DEST_DIR” > “$LOG_FILE” 2>&1` to also capture stderr. However, I liked the output from the built-In log option. Does anyone know why this might have been removed or if there is a way to get it back? Thanks.

Universal Link when app is not installed
We have universal links which takes user to various journeys in the app when user clicks on the link, however it works only when app is installed. If app is not installed link takes user to the App Store and when the user installs and opens the app, the link does not launch the intended deeplink flow. Is there any way we can pass context to app store and receive it when user opens the app? Android provides similar functionality using install referral lib. Checking if similar is possible in iOS.

🔥 Xcode 26 RC – visionOS App Icon Created with Icon Composer Appears Empty
App Icon created with Icon Composer is empty for visionOS app We are developing a universal app, and the app’s icon was created using Icon Composer. Xcode 26, RC visionOS 26 and visionOS 2.5 App Icons on macOS, iOS, and iPadOS are correct We have archived the app for macOS and iOS and successfully uploaded it to the App Store. This strongly suggests that the App Icon configuration in our project settings is correct for these platforms. App Icon issue on visionOS However, the visionOS app icon is not working as expected: When testing on the Vision Pro simulator (versions 2.x and 26.0), the app icon appears empty. When archiving and submitting to the App Store, the process fails with the following error: The app’s Info.plist file is missing the CFBundleIcons.CFBundlePrimaryIcon key for the visionOS App Icon. This suggests that the project’s App Icon settings may not be correctly applied for visionOS builds. Request for assistance We are preparing to release our app, one of the first to support Liquid Glass, and would greatly appreciate guidance on how to resolve this issue with the visionOS app icon.

SF Symbols 7: Hundreds of SF Symbols missing 'Availability' info
In SF Symbols 7 (115), there are 458 symbols missing Availability info. I only discovered this after using one that didn’t appear in iOS 18 but does in iOS 26. Questions: Are there plans to add Availability info for all symbols? If the field is blank, is there a safe latest-OS version we can assume? I realize managing 7,000+ icons is tough, but missing info like this makes development frustrating. It doesn't help that there's no build warning when a named image isn't found, it just defaults to the text label. Screenshot Screenshot of SF Symbols 7 showing three symbols missing Availability info. The symbol ellipsis.circle.badge is selected and its properties pane also shows no Availability info.

Public radar reports
Hello Apple community ! Not here to report an issue but I just wanted to make a suggestion ^^ I feel like a common frustration amongst developers is the lack of transparency over bugs filed on developer tools, SDKs, iOS versions, the whole Apple ecosystem really. This leads to the creation of parallel bug tracking tools (https://github.com/feedback-assistant/reports?tab=readme-ov-file / https://openradar.appspot.com/page/1) or filing of duplicates for reports that may already exist and are being worked on. I feel like this would save time for both external developers that encounter bugs & Apple engineers that have to look for possible duplicates to share a common public database of issues. Other companies have this kind of system in place (Google for example : https://issuetracker.google.com/) so why not Apple ? 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.

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

Missing Content from my app
Hi there! I am not a coder, but I built an app in ADALO just for in-house use in my company, PetroImaging. The app looked the way I wanted it to in the preview mode in ADALO, but when my app was approved and ready for download in the app store, a lot of content was missing. Many buttons that linked to screens were just gone - even though they were there in the preview and the buttons are formatted correctly in adalo. How can I get my content that I need back on my app so the employees can being using it?

"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?

How to install self signed certificate to iPhone simulator running iOS 18.5?
I am trying to communicate with the backend of my project. So I need to install the certificate into the simulator. I have the .pem file but when I drag-dropped it into the simulator, I got the error "Simulator device failed to complete the requested operation.". The simulator is an iPhone 16 Pro running iOS 18.5. Is there any way to install the cert to my simulator? PS: I can't use Apple Configurator or MDM because I am using the office's Mac. And I can't install anything there. So I can only do it manually.

Is this normal while developing an app on the watch?
I used to develop iPhone apps about a decade ago and am now back at it with an iPhone and companion Apple Watch app. Why does it suck so bad? I a must be doing something wrong, but what I am doing is out of the box. The majority of the time when I go to build on the watch I get: Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters. Which I then first try to force quit the app on the watch and if that does not work, reboot the watch (which is pretty ridiculous). I tried Gemini and it gave me the following explanation: This is arguably the single most frustrating error in the entire watchOS development ecosystem. As an expert, I can tell you that you are not doing anything wrong; you are fighting a fragile architecture. Here is the technical breakdown of why this happens and a workflow to mitigate it without constant reboots. The Technical "Why" This error message reveals that the issue lies in the CoreDevice (and formerly usbmuxd) infrastructure, specifically in the secure transport layer. The "Tunnel" Failure: Xcode attempts to establish a secure, encrypted tunnel (DTXConnection) to the Apple Watch to push the debugger and the app binary. Unlike the iPhone, which can sustain a high-bandwidth connection easily, the Watch aggressively manages its radios (Bluetooth vs. WiFi vs. AWDL) to save battery. The "Handshake" Timeout: If the Watch is on Bluetooth (Low Energy) when Xcode initiates the tunnel, the bandwidth is insufficient. The system tries to escalate the connection to WiFi (or Apple Wireless Direct Link). If this negotiation takes even a few milliseconds too long—due to 2.4GHz interference, router mDNS configuration, or the Watch CPU being throttled—the handshake times out. The "Previous Preparation Error": This is the insidious part. Once the handshake fails once, Xcode’s device service caches that failure state for the device UUID. It marks the device as "unreachable" to prevent the IDE from hanging indefinitely on subsequent tries. Why you see it constantly: You aren't actually triggering a new connection attempt; you are hitting the cached "failed" state immediately. Unfortunately, the solutions it gives me are: The "Wired Proxy" Method (Most Reliable) This is the gold standard for watchOS debugging. Do not rely on "Connect via Network" for the Watch directly if you can avoid it. Disable WiFi on your Mac (temporarily) or ensure the Mac and iPhone are on the exact same SSID. Plug your iPhone into the Mac via USB. Ensure the Watch is paired to that iPhone. Result: Xcode will tunnel the instructions through the USB connection to the Phone, and the Phone acts as a high-bandwidth proxy to the Watch. This eliminates the "Mac-to-Watch" WiFi negotiation failure point. Do you hit this regularly? What do you do to make for a smooth development and deployment process? Or is it really this fragile? Thanks for any help! Bryan

lldb: argument starting with hash disappears.
Here's a simple C++ program that echoes its arguments... #include <stdio.h> int main(int argc, char* argv[]) { for (int i=0; i<argc; ++i) printf("%d %s\n", i, argv[i]); } This works as expected... > ./test arg1 #arg2 arg3 0 ./test 1 arg1 2 #arg2 3 arg3 Running under lldb gives this... > lldb ./test arg1 #arg2 arg3 (lldb) target create "./test" Current executable set to '/Users/richard/Work/test' (arm64). (lldb) settings set -- target.run-args "arg1" "#arg2" "arg3" (lldb) run Process 6138 launched: '/Users/richard/Work/test' (arm64) 0 /Users/richard/Work/test 1 arg1 Process 6138 exited with status = 0 (0x00000000) I get the same if I quote the arguments, or if I add them to the run line. Stepping into main() we see the argv and args values are as though we only had the first argument. If I quote the second argument and add an initial space " #arg1" then it works. I first saw this on an M1 running Sequoia 13.1. It am now on OS 13.3. lldb --version lldb-1600.0.39.109 Apple Swift version 6.0.3 (swiftlang-6.0.3.1.10 clang-1600.0.30.1)

"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
