Xcode 11 jumps to every desktop in Mac Os Catalina I recently updated my macOS Catalina (10.15) and also updated my Xcode to version 11.1 and I'm having issue with the window. Suppose I switch from Desktop-1 to Desktop-2, the Xcode also automatically moves to the current(focused) desktop. 
P.S Only Xcode is showing such kind of behaviour.
If you right click on the application icon on the dock, you can select Options > and change the "Assign To" from All Desktops to None.
