I have designed a new icon for my app/Tahoe in Icon Composer (launched from within Xcode)but I simply cannot get it to show up. The documentation for Icon Composer spends a lot of time describing how to design the icons but goes distressingly vague/silent on how one might use it. It suggests that I should drag the file to Xcode and it will guide me as to where to put it. The app continues to use the old (pre-Tahoe) icon. I don't get any change of behaviour and I don't know what to name the file. I assume that there are no other settings that I have to change. I can't find anything on the web or in Apple's documentation: maybe I'm missing something obvious! My app is a working NSDocument-based Cocoa project. Any suggestions please.

I'm currently exploring Instruments for profiling and tracing on macOS 15.6.1. I know there is the "network connections" instrument which records TCP/UDP information, however it seems to not include the "lo0" (loopback) interface. Is there a way to configure it so that localhost traffic is included in the recording? as the application I'm tracing uses that and I want that information to be included in traces. The documentation for network-interface-detection schema makes no mention of how it detects interfaces. Thanks in advance.

My project build failed in Xcode Cloud(works well in my local Mac), and the error shows: Preparing build for App Store Connect failed The error message is not clear enough to help us find the solution to fix it. Can anyone help with it?

Hi, our builds with a Test action in Xcode Cloud are failing because of an internal Xcode Cloud crash. We see the "red cloud with an X" icon, that indicates that it's an Xcode Cloud issue, and the message says "The Test - iOS action could not complete due to an error. The error may not occur on rebuild." but this has been happening for a while now, and for repeated builds. In the artifacts there is a crash log apparently related to the "ibtoold" process, has anybody had this issue before? Thanks

Hi everyone, I'm a developer from China, and my Apple Developer Program membership is currently in the renewal period. When I click the renewal button from the banner at the top of the Apple Developer website, the page redirects but consistently shows a 503 Service Unavailable error. This has been happening for several days now. I've already tried: Switching to different devices or Changing network environments Unfortunately, the issue persists in all cases. Has anyone else encountered this same situation? Any help or suggestions would be greatly appreciated! Thanks in advance.

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.

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?

Each time I launch a Debug version of the app on iOS Simulator, I see the Launch Screen presented and then about a 30-second delay before the app is responsive and debug output appears in the console panel. Filed FB22345091

Hiya folks! I'm David and I work on rust-analyzer, which is a language server for Rust similar to sourcekit-lsp. I'm using the new Instruments profiling tooling functionality in Xcode 16.3 and Xcode 26 (Processor Trace and CPU Counters) to profile our trait solver/type checker. While I've been able to use the new CPU Counters instrument successfully (the CPU Bottleneck feature is incredible! Props to the team!), I've been unable to make use of the Processor Trace instrument. Instruments gives me the error message "Processor Trace cannot profile this process without proper permissions". The diagnostic suggests adding the com.apple.security-get-task-allow entitlement to the code I'm trying to profile, or ensure that the build setting CODE_SIGN_INJECT_BASE_ENTITLEMENTS = YES is enabled in Xcode. Unfortunately, I don't know how I can add that entitlement to a self-signed binary produced by Cargo and I'm not using Xcode for somewhat obvious reasons. Here's some information about my setup: Instruments Version 26.0 (17A5241e) I'm on an 14" MacBook Pro with M4 Pro. It's running macOS Version 26.0 Beta (25A5295e). I've enabled the "Processor Trace" feature in "Developer Tools" and even added the Instruments application to "Developer Tools". As a last-ditch effort before posting this, I disabled SIP on my Mac. Didn't help. To reproduce my issue: Get Rust via https://rustup.rs/. Clone rust-analyzer: git clone https://github.com/rust-lang/rust-analyzer.git. cd rust-analyzer Run cargo test --package hir-ty --lib --profile=dev-rel -- tests::incremental::add_struct_invalidates_trait_solve --exact --show-output. By default, this command will output a bunch of build progress with the output containing something like Running unittests src/lib.rs (target/dev-rel/deps/hir_ty-f1dbf1b1d36575fe). I take the absolute path of that hir_ty-$SOME-HASH string (in my case, it looks like /Users/dbarsky/Developer/rust-analyzer/target/dev-rel/deps/hir_ty-f1dbf1b1d36575fe) and add it to the "Launch" profile. To the arguments section, I add --exact tests::incremental::add_struct_invalidates_trait_solve. I then try to record/profile via Instruments, but then I get the error message I shared above. Below is output of codesign -dvvv: ❯ codesign -dvvv target/dev-rel/deps/hir_ty-f1dbf1b1d36575fe Executable=/Users/dbarsky/Developer/rust-analyzer/target/dev-rel/deps/hir_ty-f1dbf1b1d36575fe Identifier=hir_ty-f1dbf1b1d36575fe Format=Mach-O thin (arm64) CodeDirectory v=20400 size=140368 flags=0x20002(adhoc,linker-signed) hashes=4383+0 location=embedded Hash type=sha256 size=32 CandidateCDHash sha256=99e96c8622c7e20518617c66a7d4144dc0daef28 CandidateCDHashFull sha256=99e96c8622c7e20518617c66a7d4144dc0daef28f22fac013c28a784571ce1df Hash choices=sha256 CMSDigest=99e96c8622c7e20518617c66a7d4144dc0daef28f22fac013c28a784571ce1df CMSDigestType=2 CDHash=99e96c8622c7e20518617c66a7d4144dc0daef28 Signature=adhoc Info.plist=not bound TeamIdentifier=not set Sealed Resources=none Internal requirements=none Any tips would be welcome! Additionally—and perhaps somewhat naively—I think I'd expect the Processor Trace instrument to just work with an adhoc-signed binary, as lldb and friends largely do—I'm not sure that such a high barrier for CPU perf counters is warranted, especially on an adhoc-signed binary.

Hello! When launching/debugging on my iPad and iPhone I keep getting the following error: “Previous preparation error: Failed to find a DDI … Run ‘devicectl list preferredDDI’ …” I believe this was caused by a previously interrupted Xcode update around June due to low disk space, which may have left DeviceSupport/DDI/CoreDevice files incomplete. Even after finishing the update later, the error persists. I now use a new Mac with 4 TB of storage, but the issue still occurs. Since then I have unfortunately been blocked from testing or presenting my app on devices. It seems that only a new, fully completed Xcode update might resolve the problem. Tried so far: – Cleared caches (CoreDevice/Devices) – Reset trust on device and re-paired – Checked devicectl list preferredDDI I would really appreciate guidance, as at the moment I cannot present my app due to this blocking issue. Thank you very much for your support!

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

I have an AppleTV app which I released in 2016. I've updated it and released a new version every year without much hassle. This year, with tvOS 17.2, the layered app icon isn't working right. This is a two-layer image made with PNGs. When it's selected, it looks right and the layers move correctly: But when it's not selected, the background layer disappears: Screenshots are from the simulator but it also happens on the device. It's inconsistent; sometimes it's the front layer that disappears. Occasionally both layers work, but I can't tell why. I've spent a day trying everything. Very frustrated. The icon previews correctly in Xcode and in Parallax Viewer. The image sizes are correct: 400 x 240 for Small, 800 x 480 for Small@2x, 1280 x 768 for Large. The back layer is a non-transparent PNG. I tried adding a Large@2x set. Didn't help. Originally I had a three-layer image with no middle layer PNG. I deleted the empty middle layer, but that didn't help. All the PNG files are from GnuIMP. Same color space, even. I was using the filenames tvicon-back-s.png and tvicon-back-s@2x.png. I tried taking out the @ sign in case that was confusing Xcode. (It never has before, but I am flailing here.) Anybody have any clues? If it's an Apple bug and there's nothing I can do, I'm going to just push the release button and hope it fixes itself someday.

Hello, my Apple Developer Program had expired 20 days ago, but i cant renew in any way (auto-renew dont work, i dont have "renew button" on web, dont have it in iOS and macOS developer apps, so i cant renew it. Has anyone encountered this problem? How can i solve it and renew my membership?

why xcode has no option to fold all

I keep getting a fails to open page message when I try to sign in using my Claude ai Pro account. The request was for an http url instead of an https url.

Hi everyone. I have the following code that I am trying to execute in Xcode. I then install it on my iPhone. It doesn't run at all and I don't know why. Any thoughts? Thank you. import CoreMotion class MyViewController: UIViewController { let motionManager = CMMotionManager() func startAccelerometer() { if motionManager.isAccelerometerAvailable { motionManager.accelerometerUpdateInterval = 0.1 // 10 updates per second motionManager.startAccelerometerUpdates(to: .main) { (data, error) in guard let accelerometerData = data else { return } let x = accelerometerData.acceleration.x let y = accelerometerData.acceleration.y let z = accelerometerData.acceleration.z // Process the x, y, and z acceleration values here print("X: \(x), Y: \(y), Z: \(z)") } } } }

For me it looks like Xcode 26 has problems reading SPM packages from a locally hosted BitBucket git solution. While Xcode 16 work perfectly fine, Xcode 26 fails to load and gives "Server SSH Fingerprint Failed to Verify" as error description. Cleaning build data and DerivedData sometimes makes loading work. Any change in Package dependencies will break it again. Anyone having same problems? How do you handle it?

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.
