xcode 12.2 losing syntax color

When i change some folder/file hierarchy in navigator xcode loses color theme
or
when i open a storyboard and work on it after i switch to swift source code file again xcode loses color highlighting.

most of the text colors turns white where they should be other than white color.

some doesn't change like "func" or "import" they don't lose their purple color but most of the green-blue colored texts are turning to white.

im using macos 11.0.1 (20B29) dark theme and xcode Version 12.2 (12B45b) theme default (dark)

I have already send feedback to apple but i want to ask if anyone knows a quick fix other than "quit xcode and restart" which im doing since xcode 7...


Getting the same problem and have to keep restarting Xcode, which seems to "wake up" the syntax color. Hope they fix this soon.
