Xcode 26 & macOS Tahoe breakages

If you try Xcode 26 and notice new capabilities in Xcode 26 projects please share them here. You don’t need to touch on how Tuist generated projects should reconcile them, but if you have ideas, don’t hesitate to share them.

Xcode 26 has symbol generation for strings which is enabled by default for new projects: Code-along: Explore localization with Xcode - WWDC25 - Videos - Apple Developer

I’d:

  • update our tuist init template to align with that
  • Consider deprecating resource synthesizing for strings. I don’t really see a need for that anymore.

I ran into an issue on Tahoe when running tuist install. It was unable to find git (even installed through homebrew) and kept attempting to install the command line tools package. Xcode 26 did not set my DEVELOPER_DIR correctly and I had to manually configure it in Xcode → Settings → Locations to fix.

Errors looked like this:

 git: error: sh -c '/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.2.sdk -find git 2> /dev/null' failed with exit code 17664: (null) (errno=No such file or directory)
    xcode-select: Failed to locate 'git', requesting installation of command line developer tools.
