Peter Witham:

Is this new in Xcode 27? Pretty sure it as and I approve whole heartedly! I really hate setting up Xcode settings more than once.

Christian Beer:

Building with Xcode 27 doesn’t work because of some intransparent XCStrings error… and I even can’t check with Xcode 26 anymore because Apple decided to not let me run it on macOS 27…

Steven Woolgar:

After all these years Apple has finally broken cmd-e in Xcode 27.
