The Menu command to create a new project based on a Package.swift file is gone. How am I supposed to do this now?

It seems that the behavior of the .copy rule in SPM packages has changed in Xcode 27. This change now results in raw files being copied into the bundle without compilation, resulting in crashes and missing resources since uncompiled resources cannot be used by the OS. More specifically, in Xcode 26, when .copy was applied to resources such as storyboards, asset catalogs, etc. it would cause Xcode to compile those resources into the respective storyboardc or Assets.car before copying. Xcode 27 does not do this and instead copies the raw files. I do understand that there is a difference between .process and .copy, and the documentation does state that the process rule needs to be used for those files. Is this a regression in Xcode 27 or is copy not compiling anything expected behavior? Submitted FB23115950

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?

Hello, I’m trying to use a third-party MCP server (ICM) in Xcode 27’s new Coding Assistant. The server appears to start correctly and shows up when I run /mcp, but as soon as an agent tries to use it, Xcode appears to rewrite my config and changes "enabled = true" to "enabled = false". My configuration looks like this: [mcp_servers.icm] command = "/opt/homebrew/bin/icm" args = [ "serve", "--no-embeddings", "--db", "/Users/Sam/emdash/worktrees/Castle/emdash/custom-widget-system-5dubi/.icm-xcode/memories.db" ] enabled = true I’ve spent quite a while debugging this and found some interesting behaviour: The MCP server appears when I type /mcp. SQLite databases can be created and written inside the current workspace. SQLite databases can also be created and written in /tmp. SQLite databases outside the workspace (for example in ~/Library/Application Support) fail with readonly/open errors. Ordinary file operations outside the workspace still work fine. What I’m trying to understand is: Why is Xcode disabling the MCP server? What filesystem access should MCP servers have? Are they intentionally restricted to the workspace and /tmp? Is there a supported way to allow an MCP server to access data stored elsewhere on disk? Has anyone else run into this? Thanks!

The process of copying shared cache symbols from my Apple Watch has been horrendous. I cannot even get past 2% complete before this process fails. Every device is on the same network. I have trusted my machine. Developer mode is enabled on the watch. I have successfully paired the phone and watch. I managed to install an Watch app onto the watch. But the shared cache symbols were never copied from the watch. I gathered several commands at the terminal to help me. rm -rf ~/Library/Developer/Xcode/DerivedData rm -rf ~/Library/Developer/CoreDevice sudo killall -9 remoted CoreDeviceService 2>/dev/null || true xcrun devicectl manage ddis update xcrun devicectl list devices Clear CoreDevice state.

I have a workspace containing a DriverKit USB driver and the containing application that utilizes the driver. These are in separate projects. How do I configure the application project or the workspace so that, when I build the app, the driver is automatically built and copied into the application package as required for delivery? Currently I have to manually select the driver target, build, and then select the app target and build. In order to get the driver into the app, I have included it as a build-phase dependency but I had to hardcode the driver project output path and it doesn't build it automatically. Additionally, because I hard-coded the debug path, when I try and create an Archive to deliver the app, the app includes the debug version of the driver instead of the release version. I'm obviously doing this wrong because it is as clunky as can be.

I wasn't sure if I should post this to the gaming subsection or here, but since this is an Xcode crash, I thought I'd try here first. I originally made this Spritekit game a few years ago on an old 2012 intel mac stuck on Catalina. When bringing the project over to Xcode 26, I first had to download Xcode 10 on the old mac, upgrade the project to swift 4, then bring it over to my newer machine to even be able to open it in Xcode 26. All that being said, I'm sure this process had some unintended consequences. I wasn't getting this crash before converting the project to swift 4 and bringing it over to Xcode 26. As you imagine, the entire Xcode crash report was massive. Near the top of the report there is I believe some crash relevant crash information, but google wasn't much help with the error codes and I don't know what to make of it: Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: Namespace SIGNAL, Code 6, Abort trap: 6 Terminating Process: Xcode [55897] I have no idea how to tackle this problem since I can't even get in to the scene to look around, nor does Xcode have time to throw any specific scene errors. The game runs just fine, including that level. I can play through the entire thing on device or simulator with no issues, but if I click on the .sks of level 3 in Xcode, Xcode immediately crashes. Closing Xcode and trying to open the .sks in question by itself via finder also immediately causes an Xcode crash. I can open up the other levels in the finder just fine.

Hi everyone, quick question, as the title suggests: is there a mode that bypasses permission requests for actions that aren't already in "Always Allowed" mode? Something like Claude Code's "dangerously skip permissions" setting. It's quite annoying to see his conversation ask for permission dozens of times; Thanks!

Do you need to be on macOS 27 beta for the agents to work well in Xcode 27 beta? I tried using the agent yesterday in Xcode 27 beta on my Mac that isn't on macOS 27 beta yet (it's on 26.5.1) and it was very slow and just kept stopping without actually performing the steps. I did send a feedback. I was using a chat provider that is made available within our enterprise which provides access to many LLMs.

How to download iOS 27.0 Universal simulator in Xcode 27.0 Beta 1 ? xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -architectureVariant universal -buildVersion 27.0 Finding content... iOS 27.0 (universal) is not available for download.

I'm trying to build a Mac Catalyst version of our iOS (iPad) app but the build always fails with 'Internal error, please file a bug at ...' when compiling MainWindow.xib file. (I have already filed a bug.) The error in the log.txt file is: "Failed to compile nib consisting of IBProxyObject (x2), IBUICustomObject (x1), IBUINavigationBar (x1), IBUINavigationController (x1), IBUINavigationItem (x1), IBUIToolbar (x1), IBUIViewController (x1), and IBUIWindow (x1). Exception name: IBPlatformToolFailureException Exception reason: The tool closed the connection (IBAgent-macOS-UIKit)" The same .xib file works fine when building an iOS version of the app and it worked for MAC catalyst until Xcode v26.x. I've already tried cleaning the build folder, deleted project DerivedData folder, replaced all custom classes with base classes and tried other suggestions found in the internet but nothing seems to help.

Hi everyone, Since today, all my Codex requests have been failing in both Xcode 26.5 and Xcode 27 beta. The Codex integration appears to be connected and authenticated correctly, but every request fails immediately with the error shown in the attached screenshot. Error message: The data couldn’t be read because it isn’t in the correct format.

How do you prevent Xcode global resource conflicts when utilizing git worktree? I am adopting git worktree to manage multiple concurrent branches of our iOS project simultaneously. While Git handles the isolated source files perfectly, Xcode struggles because it relies heavily on global, centralized states behind the scenes. When opening multiple worktrees concurrently in Xcode, I run into several breaking issues with globally shared resources: DerivedData Collision: By default, Xcode hashes the project path/name to generate a folder in ~/Library/Developer/Xcode/DerivedData. Because the project files have identical names (just different root directory paths), Xcode occasionally maps them to overlapping cache locations, causing incremental build corruption. Swift Package Manager (SPM) Fetching: The global SPM cache (~/Library/Developer/Xcode/DerivedData/../SourcePackages) seems to choke or trigger duplicate index/fetch cycles when two worktrees try to resolve dependencies at the same time. Simulator/Previews Overwriting: Running an app from Worktree_A installs it on the simulator. Running it from Worktree_B overwrites the exact same App Sandbox container, destroying test data. My Question: What are the best practices, custom build configurations, or tooling scripts to safely isolate Xcode instances when working across multiple active Git worktrees? How can we force Xcode to treat each worktree as a completely independent environment?

What are the best practices for a painless physical watchOS debugging loop in Xcode? Debugging a standalone or companion watchOS app on a physical Apple Watch is arguably the slowest feedback loop in Apple development. Every minor code change often results in Xcode getting stuck on "Installing to Apple Watch" for minutes, or throwing a "Failed to attach" LLDB error after a long timeout. The biggest bottlenecks seem to be: The initial Symbol Copying / dyld shared cache sync: This takes forever whenever watchOS gets updated. Can these symbols be pre-cached or manually downloaded on the Mac via an internet connection rather than pulling them byte-by-byte from the watch? Slow Installation over Bluetooth: The watch often defaults to a sluggish Bluetooth link with the iPhone instead of leveraging local Wi-Fi or the direct Mac-to-Watch network tunnel. Debugger Connection Timeouts: Xcode routinely loses track of the target process before the app finishes launching on the watch. My Question: What are your recommended workflows, hidden Xcode flags, build settings, or networking setups to make physical watchOS debugging as close to the simulator experience as possible? Specifically, how do we handle symbol caching and force faster deployment pipelines?

How to trace/find all usages of a variable or constant in Xcode? I know that I can use Find > Show Callers (Ctrl + Cmd + Shift + H) in Xcode to instantly find every place a function or method is executed. However, this feature frequently returns "No Callers" or fails completely when I try to use it on a global or instance variable (var or let). Using a standard global text search (Cmd + Shift + F) works, but it returns a lot of noise, including comments, unrelated strings, and matching text in completely different scopes. My Question: What is the best, most reliable way in Xcode to find only the actual structural references (reads and writes) of a specific Swift variable across a project? Is there a built-in static analysis tool or shortcut designed specifically for data tracking rather than function execution?

from: WWDC26 - Xcode Tips and Tricks Group Lab user:bondad? asked Why does selecting "Show Callers..." on a symbol sometimes show a ? icon when the symbol definitely has callers? great question - I've often wondered this, too!

Could you please add support for https://agents.md in Xcode coding intelligence? By default or at least optionally add the AGENTS.md file to coding agent sessions.

Is there a way to configure Coding Intelligence to use Codex as an automatic code reviewer for Claude (or vice versa)? https://community.openai.com/t/introducing-codex-plugin-for-claude-code/1378186
