I’m running a Xcode 12.0 beta (12A6159) on macOS 10.15.5, and this looks like a bug:
Could you please confirm that this is a known issue?
Thanks!
Open a project in Xcode
Click a source file in the Navigator
The source file is open in the Editor now
Hit Control-Command-W to close the Editor
🐞 The Editor stays open
Check the File menu, the Close Editor menu item is disabled
Could you please confirm that this is a known issue?
Thanks!
