All my colorLiterals have been replaced with : (Color(#colorLiteral(red: 1, green: 1, blue: 1, alpha: 0.7)))
The visual queue of having the actual colored icon was pretty great. also the ease of double clicking to change on the fly.
What gives?
Xcode 13 not allowing the use of colorLiteral
Seems to be the known issue (at least, known by us developers):
Color literal not displaying as Color Swatch?
You should better send a bug report to Apple.
