Hey all, the codex sign in isn't working for me in Agents. I am using the 26.5 release candidate version. It always says "Not Signed In". I have completed the Sign In process multiple times. Anyone else seeing this? I have filed Feedback FB22732574

When tapping on Info.plist the editor area stays completely empty and doesn´t show Info.plist

Tried to execute our XCUITest test suite with XCode 27b6. The test plan is set to run in parallel. When executing tests locally with XCode 26, I can see the clone simulators executing the test (which is useful for debugging the test). With XCode 27b6 and Device Hub, I do not see the clone simulators executing, nor do I see a setting or menu item in Device Hub to show those clone simulators. There is no equivalent to the "Show Parallel Testing Devices" menu item in the XCode 26 sim. Am I missing something or is this a regression in XCode 27?

After tapping topmost project name in navigator area xCode won´t show the editor area to update the Project / Target pages and General tab

I am unable to download and install the iOS Simulator runtime in Xcode 26.6. Environment: MacBook Air with Apple silicon macOS Tahoe 26.6 Xcode 26.6 Build version 17F113 xcode-select -p: /Applications/Xcode.app/Contents/Developer xcodebuild -showsdks correctly reports: Simulator - iOS 26.5 -sdk iphonesimulator26.5 However: xcrun simctl list runtimes returns: == Runtimes == No Simulator runtime is installed. In: Xcode > Settings > Components I attempted to install: iOS 26.5.1 + iOS 26.5 Simulator but it remains at: Preparing... for a very long time without actually downloading the runtime. I also tried: xcodebuild -downloadPlatform iOS This eventually failed with: Download was cancelled exit code 70 I also tried: xcodebuild -downloadPlatform iOS -exportPath ~/Downloads/XcodePlatforms The destination directory remains at 0 bytes. Checks already completed: More than 860 GiB free disk space Mac restarted Xcode quit and reopened xcode-select points to the correct Xcode installation /etc/hosts contains no Apple blocking entries gdmf.apple.com resolves correctly HTTPS connectivity to gdmf.apple.com works Apple MobileAsset / software update services are running iOS Simulator SDK itself is installed correctly The project can compile for iphonesimulator26.5, but Simulator execution and tests are blocked because no runtime can be installed. Questions: Is this a known issue with Xcode 26.6? Is there an official alternative way to download the iOS Simulator runtime? Can I install an earlier supported iOS Simulator runtime instead? Is there a MobileAsset or Xcode cache reset procedure recommended by Apple? Thank you.

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

For the life of me, I cannot find how to bring up the Siri Remote in the Apple TV Simulator in Xcode 27 Device Hub (Beta). Is it no longer available? I have always seem to have had issues using the computer's keyboard for navigating my tvOS apps. Maybe it's me, but the Siri Remote always worked perfectly fine. I hope the remote will make a reappearance in the next beta... ?

Xcode 27.0: Apple TV Simulators fail to navigate to some buttons in a UIViewController via keyboard arrows. Works fine with Xcode 26 (Siri Remote) simulator and also works as expected on an actual Siri Remote for Apple TV device running tvOS 27 Beta. Anyone else experience issues with navigating their app's UI using the Mac keyboard in Device Hub? Any tips for tracking this down?

When I try to download the metal toolchain 26.6 (17F109) in Xcode it just stays on preparing to download. Does anyone have an idea on how to fix this? I'm on macOS 26.6.1 (25G76)

Hi systems programming guys. I’m exploring the macOS as a low-level itself, so when I use the otool(1) utility to inspect a tiny objc helloworld program, it told me that there is a shared library like /usr/lib/libobjc.A.dylib (not identical) but I didn’t find that in path /usr/lib/. Also the docs sucked (see below). I want to know more details about the objc runtime on macOS (beta 27.6 +) and be seeking for help here because there are few materials online and not even to say the sucked AI. The prima motivation is the runtime itself and how it works. Of course I would love to read disassembled code and manpages or using utilities that Apple offered to understand those things . But I really don’t know where is the runtime if both docs and otool output lied. The latest documentation about Objective-C Runtime is outdate and it said “Objective-C runtime library support functions are implemented in the shared library found at /usr/lib/libobjc.A.dylib.”

Hello, I am very new to programming for iPhone, so please excuse me if this question is ignorant and I'm missing something silly. I am trying to build an app for my phone (iPhone SE 3rd gen) using my Macbook Air (same Apple Account). I downloaded XCode and started with the default "Hello World!" template. I created a personal team and figured out all the settings on my phone (trusted the computer, turned on developer mode, trusted the account). However, after uploading, I get the following error: The weird part is that I have a stable internet and cell connection. Following the instructions given to me in the similar error on my Mac, I head to General -> VPN and Devices -> my account and click "Verify App". This gives me a pop-up: Clicking Verify, it loads for a second and absolutely nothing happens. Not sure how to proceed or what's wrong.

In Xcode 27 Beta 4 (27A5228h), building a project that has a SwiftPM binary target (xcframework) linked directly from both an app target AND a framework target that is embedded in that app fails with "Multiple commands produce" errors. The same project and pbxproj builds successfully in Xcode 27 Beta 3 (27A5218g), so this is a regression introduced in Beta 4. Steps to Reproduce Create a new iOS App project. Add a Framework target (e.g. "SampleCommon") and embed it into the app. Add a SwiftPM dependency for a package that vends a binary xcframework product. Confirmed with airbnb/lottie-spm 4.6.1 (https://github.com/airbnb/lottie-spm). In "Frameworks, Libraries, and Embedded Content" of the app target, add the SwiftPM product (Lottie) with "Embed & Sign". In "Frameworks and Libraries" of the framework target, add the same SwiftPM product (Lottie). Build the app scheme for iOS Simulator. Expected result Build succeeds. The xcframework is embedded exactly once into the .app bundle. This is the behavior in Xcode 27 Beta 3 and Xcode 26. Actual result Build fails with: error: Unexpected duplicate tasks error: Multiple commands produce '.../<App>.app/Frameworks/Lottie.framework/Lottie' error: Multiple commands produce '.../<App>.app/Frameworks/Lottie.framework' Two Copy tasks are emitted for the same output path in the app target: Copy from Build/Products/Debug-iphonesimulator/PackageFrameworks/Lottie.framework Copy from SourcePackages/artifacts/lottie-spm/Lottie/Lottie.xcframework/ios-arm64_x86_64-simulator/Lottie.framework Additionally, an auto-generated target named "Lottiedynamic-product" emits duplicate MkDir / ProcessInfoPlistFile tasks for PackageFrameworks/Lottie.framework, which suggests the packaging path for binary xcframework products has been duplicated in Beta 4. Regression Xcode 27 Beta 3 (27A5218g): builds successfully Xcode 27 Beta 4 (27A5228h): fails with the above errors Xcode 26.x: builds successfully Minimal reproduction The issue reproduces on a 2-target Xcode project (app + framework) with airbnb/lottie-spm added and linked from both targetstory captures the smallest triggering diff: pattern1: app links Lottie only -> BUILD SUCCEEDED pattern2: framework links Lottie only -> BUILD SUCCEEDED pattern3: both app and framework link Lottie -> BUILD FAILED (only on Beta 4) Only the framework target's packageProductDependencies and Frameworks build phase entries differ between the succeeding and failing states. Workaround Link the SwiftPM binary product from only one target (either the app or the framework, not both). If only the framework tarl gets the framework transitively at runtime. Impact Any project that uses a SwiftPM binary xcframework and organizes code across multiple linked targets (a very common pattern for larger apps) is blocked from adopting Xcode 27 Beta 4. Environment Xcode 27.0 Beta 4 (27A5228h) macOS 26.5.2 Package: airbnb/lottie-spm 4.6.1 Destination: iOS Simulator (iPhone 17, latest)

First of all, let me just state that I'm trying to create an app with an AI, so if that's not allowed in this forum, let me know. I'm not an experienced app developer, far from it, so please excuse my ignorance. I have used PC/Windows machines for decades, so the Apple/Mac stuff is foreign to me. My app development but ran into a snag. We're trying to get the app in Xcode to test run on my iPhone 16 Pro. It works in the simulator but fails on the iPhone. It all boils down to the keychain password that keeps popping up. I have only created four different passwords for Apple/Mac and Keychain won't accept any of them. How do I change the keychain password? I have read articles on it but no luck. Appreciate any help. '24 Mac Mini, M4, Tahoe 26.6.2 Xcode 26.6

In the video "Xcode, Agents and You" (direct link), the presenter asks for a walkthrough of the open project and Xcode presents a rich-text overview of the app's architecture, with color-coded diagrams and clickable links to the files it discusses. I can't get that to work when I try it, though. Is this a preview of a feature that isn't yet available in the first beta of Xcode 27? Is this because I'm using a local model or because it only works with a specific kind of model?

I can't use cloud-based AI providers, so I'm very excited about the potential of local models with Xcode's Coding Assistant. I've been playing around with a local MLX model, and have been generally pretty satisfied with it. But I'm curious - what features am I missing out on by using a local model instead of a larger, cloud-based model? Is Xcode's ability to run tests, build the project, etc. limited by the use of a local model? Does it limit the ability to do more complex agentic workflows? If so, how? Basically, local models in Xcode seem to be working pretty well for me, and I'm curious to know what cloud-based models can offer that I don't already have.

In a Playground in Xcode 27 beta 6 I don't see a way to make a new page. It used to be File->New->Playground Page. That menu item is missing. The keyboard shortcut still exists, but it produces an error "No valid file actions for insertion." Am I missing an alternative? Or is this no longer possible?

Hello, I am trying to use XCode to generate a 'embedded.provisionprofile' file. My Xcode macos project keeps giving me an error saying: Provisioning profile "BRandNewMebedded" doesn't include signing certificate "Apple Distribution: Martin Barker (LV6WXG529F)". When I download the Provisioning Profile file "BRandNewMebedded" from online, I make sure it has "Mac App Distribution" checked, but even if i edit it to use the first option "Distribution" and re-download it, my XCode keeps saying the same error in red.

Hi, I am trying to make my app build on GitHub Action CI pipeline. App builds fine on xcode on my mac. For CI I am using command line xcode. I am getting following error: No profiles for 'com.snslocation.electricians-now' were found: Xcode couldn't find any iOS App Development provisioning profiles matching 'com.snslocation.electricians-now'. Automatic signing is disabled and unable to generate a profile. To enable automatic signing, pass -allowProvisioningUpdates to xcodebuild. (in target 'myapp' from project 'myapp') You can see full log of the build here: https://github.com/nbulatovi/ElectriciansNow/actions/runs/12603115423/job/35127512689 The provisioning profile is present, and verified in the previous steps in the pipeline, however xcode refuses to find it. If I add -allowProvisioningUpdates error stays. I tried manually mapping app id to profile name. Is there a way to get any debug log from xcode profile search, to see why is it not picking up the correct profile? Or can you maybe help in some other way? xcode version is 15.4, iOS SDK 17.5
