[xcodebuild]

works with The Unarchiver but not with default Archive Utility

It works fine with either the system Archive Utility and The Unarchiver when I try. 🤔

Moreover, when inspecting with BetterZip, the particular file rights seem to be okay for all the app bundle, folders and the actual executable:

all of them having the x right present. This ZIP is also used by Sparkle and Homebrew, both seem to unpack the app properly.

Any other idea how shall we debug this?

I download zip from release and unzip it again, it works fine this time...
