I’ve been working on a plugin project and I usually work in the standalone app as I’m developing. Yesterday, everything was just fine. This morning, same project, nothing has changed, but it’s now failing code sign.
/Users/me/projects/MyThing/Builds/MacOSX/build/Debug/MyThing.app: code object is not signed at all
In subcomponent: /Users/me/projects/MyThing/Builds/MacOSX/build/Debug/MyThing.app/Contents/MacOS/MyThing.ld_mSGwzw
Command CodeSign failed with a nonzero exit code
I checked the Signing settings and everything looks good, Automatically manage signing is set, I see my Team and Development Certificate all there, not expired.
Xcode 13, Big Sur 11.6
