Hey! I am writing type formatting scripts in Python for lldb, as described in https://lldb.llvm.org/use/variable.html#python-scripting. I'm trying to pass an environment variable to lldb from Xcode to determine the path to the scripts in the project root, so the project is not bound to some predetermined path. I am having trouble doing this in Xcode. What I have tried: lldbinit file Create a .lldbinit file in $(SRCROOT) with the following content: platform shell echo $SRCROOT. Set the path to the .lldbinit file in Edit Scheme... > Info > LLDB Init File ($(SRCROOT)/.lldbinit). Set the SRCROOT environment variable to $(SRCROOT) in Edit Scheme... > Arguments > Environment Variables. entry-point breakpoint Add a breakpoint to the entry-point of the application. Set the Automatically continue after evaluating actions option. Add the action platform shell $(SRCROOT) or platform shell $SRCROOT. Set the SRCROOT environment variable to $(SRCROOT) in Edit Scheme... > Arguments > Environment Variables. What I expect to happen: The first line of the debug console is a path pointing to $(SRCROOT) What actually happens: No path is output Is this functionality available in Xcode Version 26.0.1 (17A400)? Thanks in advance, Barnabas

Hi, I'm working on an app that integrates third-party UWB accessories using the Nearby Interaction framework. I want to display real-time data via Live Activities, and ideally, I hope the app can continue ranging/interacting with the accessory even when it's in the background—triggering updates in the Live Activity. Specifically: Can I use Live Activity to keep Nearby Interaction sessions running in the background, as long as the accessory is still nearby and connected? Or do I always need to initiate sessions in the foreground? Are there ways to maintain or trigger new Nearby Interaction sessions entirely in the background, when using third-party UWB accessories? Is there any official guidance regarding permissions, user authorization requirements, or restrictions for background ranging with third-party hardware? Are there recommended strategies or patterns for updating Live Activity widgets with data from Nearby Interaction or UWB accessories while backgrounded? (e.g. Bluetooth triggers, push notifications, background tasks) Any advice, experiences, or official recommendations would be greatly appreciated! I want to ensure my implementation is compliant and offers the best possible user experience. Thanks!

my Objective-C/Swift mixed project using cocoapods started experiencing persistent Swift code highlighting issues. Partial highlighting loss but when i use "compare code" function of the editor, It shows that everything works well on the compared code. rename also can not be used any more. does anyone know ho to fix this?

What possessed Apple developers to redesign the Behaviors UX? It is not as flexible, and at least Custom Behaviors do not work all the way through 26.2beta. You cannot name or rename behaviors. It just keeps "New Behavior." You cannot delete behaviors. Running shell scripts does not work. I gave up after that. Why was the Xcode 16 model changed and NOT TESTED!

Hey there! I recently noticed that when using Xcode Code Intelligence, it repeats itself within the response. Is this a normal occurrence, or is there an issue with the LLM itself? I’m using MistralAI Codestral as my LLM.

Where are the instructions for this process

Hey everyone, after signing in to my Apple Account in Xcode and I click on it, I keep getting the "Failed to retrieve development teams for xyz". I have a developer account (Individuals), however not paid one yet as I'm not that close to finish my app. I'm using the latest version of everything, signed out and back in multiple times from my accounts. Any idea why this is happening and how to fix it?

Hello, When trying to login into my ChatGPT Enterprise account within Xcode 26 to setup Coding Intelligence, after credentials and OTP have been accepted, I'm getting the following error message from ChatGPT/OpenAI: Route Error (400 ): { "error": { "message": "No eligible ChatGPT workspaces found.", "type": "invalid_request_error", "param": null, "code": "chatgpt_account_missing" } } What am I missing here? Any help is highly appreciated. Thank you!

Hello On Nov 11, 2025 I upgraded Xcode to 17B100 I found instructions to install it on an external drive because the old way of doing it (install to /Applications and move it to the desired location) didn't work. I downloaded the dmg, moved it to the external drive and the install worked I now have a usable Xcode sitting on my external drive The problem is, there are no simulators and the normal method of downloading them does not work. How do I install simulators (preferably on my external drive) for use by my externally installed Xcode (same drive)?

90714: Invalid binary. The app contains one or more corrupted binaries. Please rebuild the app and resubmit. 我开发的OC项目，三个月前打包分发还没有问题，半个月前开始就一直报这个错。查了很多资料都无法解决，所有的SDK也都升级了，还是报这个错，麻烦Apple的工程师帮忙指正一下问题，如何解决这个问题。

Hello, Is there any plan to integrate realtime sanitier (RTSan) in Apple Clang? This tool has been introduced in Clang 20.1.0 back in March 2025. This tool is incredibly useful, and having it in AppleClang (and ideally integrated in Xcode and xcodebuild) would be great. Thank you, Best, Thomas

I cannot install ios device support using Xcode-Settings-> Components. I lost my support for my ios devices. My system ran low on disk space. All of a sudden my Schemes only show Get IOS support for my iPad and iPhone. Both devices run older ios versions : 18, 16. Any ways the Xcode-Settings-> Components just tries to force me to update ios. I don't want ios 26 yet as my app I developing does not play well with it. I may try the remove XCode, restart Mac and fresh install xcode 26 to see if this fixes it. Unpairing/Repairing devices to mac does not start the autodownload of the support files.

Hello, I’ve looked at a video and have tons of research and I’m trying to see if there is a way core audio can be created in Xcode as an audio device? “keep in mind” I am totally new to apple’s developer forums and I do not know anything about Xcode nor on how to create an audio device of coreaudio on a Mac since there’s a lot stuff that has do with coding. Nor am I good with that type of technology.

Out of nowhere I got some red banner on top of my iPhone 13 mini / iOS 17.5. I cannot pin point the root cause of this. What I can say is that it only happens to Simulators of a certain type, e.g. iPhone 12 and 13 mini, but not iPhone 14 for example. I have installed Xcode 26.1.0 and 26.1.1, out of which 26.1.0 is selected: $ xcode-select -p /Applications/Xcode-26.1.0.app/Contents/Developer And following runtimes: $ xcrun simctl runtime list == Disk Images == -- iOS -- iOS 17.5 (21F79) - CF933623-A258-44F8-B248-C0F25C0C343B (Ready) iOS 26.1 (23B80) - D11C3CDC-EE3D-44CC-8B92-9B7D00B54B0B (Ready) Total Disk Images: 2 (14.6G) Installing the newer 26.1 23B86 runtime doesn't help either.

Release notes of Xcode 26.2 https://developer.apple.com/documentation/xcode-release-notes/xcode-26_2-release-notes state that Swift 6.2.3 is shipped with it. But when trying to check the Swift version with #if swift(>= 6.2.3) it returns false. Running swiftc -version returns swift-driver version: 1.127.14.1 Apple Swift version 6.2 (swiftlang-6.2.3.3.2 clang-1700.6.3.2) As you can see, there is a mismatch between the marketing version "6.2" and the build version "6.2.3.3.2". Being able to check for the 6.2.3 version is important for my team, because we are impatiently awaiting the change to the tabviewbottomaccessory modifier https://developer.apple.com/documentation/swiftui/view/tabviewbottomaccessory%28isenabled:content:%29 so that it can be hidden when not needed. Without this fix we have the issue that the accessory shows even without content in iOS 26.1.

I have download the 26.1 simulator after updating app this morning then out of the blue Xcode prevents me from running app and forces me to download sim again.

Hi everyone, In the previous Xcode version, I was using Intelligence with ChatGPT to refactor and fix code. It worked great: it applied changes across files in a few seconds and the code preview updated quickly. In the new Xcode version, something strange is happening: • With Claude, responses are almost instant. • With ChatGPT, it starts fine but then it shows the entire file instead of just the relevant section and, after a few lines, it starts streaming character by character, becoming extremely slow. This only started after updating Xcode. Is there any setting (streaming, token limits, formatting, etc.) that I can tweak to get ChatGPT back to the previous performance? Is anyone else seeing this issue with ChatGPT in Intelligence, or is it just my setup? Thanks in advance for any help!
