Apple Watch Missing Developer Mode Option
I have an iPhone 14 running iOS 16.1 and my series 5 watch running watchOS 9.1. I was able to turn on Developer Mode on the phone by going to Settings--> Privacy & Security --> Developer Mode. On the watch however (I'm doing this directly on the watch and not on the watch app on the phone) once I'm in Privacy & Security, there is no option to select Developer Mode. How do I get my watch in Developer Mode in order to get a successful build in xCode?

Include the release date and sw_vers in macos release notes
This is not exactly a feedback about the forums but I couldn't find a better location to ask this question. The macos release notes are hosted at developer.apple.com. For example, the macos 26.4 release note is here https://developer.apple.com/documentation/macos-release-notes/macos-26_4-release-notes. Would it be possible to include the release date in those release notes? Right now, it's hard to locate that information. It would also be useful to even include the sw_vers of that particular release in those release notes. For example: ProductName: macOS ProductVersion: 26.4 BuildVersion: 25E246 Having the sw_vers and the release date in the first few lines of the release note would be handy. The reason I went looking for the release date was because the corresponding sources for macos 26.4 hasn't yet been listed at https://opensource.apple.com/releases/. It usually takes a few days for that to happen, so I wanted to see how long it has been since 26.4 was released.

Family Controls Entitlement NOT applied to App Extensions (and Support Form is broken)
Hello, I am facing a critical issue where the Family Controls (Distribution) entitlement is not being applied to my app extensions, despite the main app ID being approved. Main App ID: com.hayashikento.focuspact (Approved on March 13) Extension ID 1: com.hayashikento.focuspact.ShieldActionExtension (Pending/Not visible) Extension ID 2: com.hayashikento.focuspact.ShieldConfigurationExtension (Pending/Not visible) I have submitted requests multiple times, but the entitlement does not appear in the "Capability Requests" for these extensions in the Certificates, Identifiers & Profiles portal. Furthermore, I am unable to contact Developer Support because the "Contact Us" form on the developer website consistently shows a "Request error" or freezes on the submission page. Since I am completely blocked from TestFlight distribution, could someone from Apple please look into my account (Team ID: UHG4J7F7NH) and manually sync these entitlements? Thank you for your help.

Need MetricKit Implementation details for MacOS background Application, mainly for
Hi, We are trying to integrate Metric Kit into our MacOS Application. Our application is a background process. We are interested in getting CPU and Memory metrics for our process. MXMetricPayload is the one we are looking at. We tried to integrate metric Kit and left the background app for 24 hours, we did not get any callback. So, does metric kit work for background app in MacOS? Also does it for Network Extension?

LLMs/AGENTS for legacy codebases
Hello there everyone. I've got numerous support projects using old school development. Things from Objective-C to RxSwift and UIKit. I've tried the LLM/Agents and they just destroy the codebase over time, so I have given up. The final straw was trying to get it to fix a POSTCODE validation issue which was using some novel ways to provide validation in place using RxSwift. Has anyone had any luck with these LLMs on Legacy codebases? Would love to hear tips.

CarPlay Simulator (from Additional tools) stuck on "Connecting to phone" since March 4th
We're experiencing an issue where the CarPlay Simulator (from Apple Developer Additional Tools) stopped connecting to our iPhones as of March 4th, 2025. The simulator gets stuck indefinitely on "Connecting to phone" and never completes the pairing. Environment App: Oracle Field Service iOS app (with CarPlay support) Tool: CarPlay Simulator from Apple Developer Additional Tools (developer.apple.com/download/all/) Issue start date: Wednesday, March 4th, 2025 Tested on: Multiple Mac machines, multiple iPhones Multiple CarPlay Simulator versions tested What's happening The CarPlay Simulator launches but displays "Connecting to phone" indefinitely. It was working correctly prior to March 4th with no changes on our end. What still works CarPlay functions correctly when the same iPhone is connected to a real car, confirming the issue is specific to the simulator. Troubleshooting steps already attempted Reset permissions and re-added the simulator Forgot the simulator and re-paired it Changed the USB cable Tested on multiple Mac machines Tested on multiple iPhones Tried multiple versions of the CarPlay Simulator Confirmed no VPN is in use Confirmed with IT, no OS updates or enterprise restrictions were applied Questions Has anyone else experienced this since March 4th? Was there a change in CarPlay Simulator behavior or a requirement on the Apple side (certificate, entitlement, protocol) around that date? Is there a known workaround or fix?

The future of Rosetta
Hello, From what I have heard, macOS will soon phase out Rosetta. I was wondering if Rosetta will still be available to install separately (instead of being preinstalled). I don't use Rosetta to run applications, because all the applications I use are ARM. However, for my YouTube channel, I often use the -arch x86_64 flag with clang. I do this so I can show the result from objdump and teach x86_64 Assembly, while also running the program through Rosetta. This may be a very niche use case, however I was still curious. Thank you!

pkgbuild on Tahoe fails to build packages if any directory name contains non-ascii characters
pkgbuild on Tahoe (26.3.1) fails to build packages if any directory name contains non-ascii characters. pkgbuild is able to build successfully with the same source data on previous versions on macOS, so this is a regression and prevents us from build able to build our products on macOS 26. Example that demonstrates the issue: mkdir -p MyAppData/Taishōgoto echo "Testing" >> MyAppData/Taishōgoto/Content.txt pkgbuild --identifier com.example.MyAppData --install-location '/Library/Application Support/MyAppData' --root MyAppData myappdata.pkg Error messages: parent directory ./Taishōgoto does not exist pkgbuild: error: Cannot write package to "myappdata.pkg". (The file “package.bom” couldn’t be saved in the folder “NSIRD_pkgbuild_52fPuN”.) I have submitted this via Feedback Assistant (FB22312299). I have not found a workaround. Tried copying pkgbuild from Sequoia but the problem persisted, probably because the buggy code is in PackageKit rather than the tool itself.

symbolicate crashlog using .symbols files instead of dSYMs
Hi, Some crashes downloaded from TestFlight aren't symbolicated by Xcode and I don't know why, here's an example: Although all uploaded builds contain debug symbols (Symbols directory with .symbols files) and other crashlogs in the same version are symbolicated just fine (also visible on the above SS). I have access only to the .symbols files but not to the original dSYMs and I wonder how to perform symbolication manually. I tried pointing atos and symbolicatecrash utilities to respective .symbols file, but they are unable to work with it. I'm sure it's possible as TestFlight symbolicates crashlogs using only .symbols files somehow. Could you give a hint?

Developer app on the Mac doesn't play videos in full screen
Hi, Problem When playing videos on the Developer app on the Mac, there is no full screen button for the video. So it is not possible to play the video in full screen. Note I am not referring to the app going into full screen, the issue is with there is no option to play the video in full screen. Environment OS: macOS 26.2 (25C56) Developer app: Version 10.8.3 (1083.3.1) Feedback FB21343934 Recording Question Are others also facing this issue? Is there a workaround? Suggestion This seems to be recurring problem that seems get broken with app / OS releases. Please write some UI tests to ensure the full screen button is present. Would really appreciate if this gets fixed.

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
