I use Xcode every day. Today, a message suddenly appeared - "Developer Tools Access needs to take control of another process for debugging to continue"   This has not happened before.

When I use Xcode it regular shows me a message "Xcode requires additional components..."   It was earlier, when I used Hi Sierra and Xcode 10, and today, when I installed Catalina and Xcode 11.   What is it? Is it normally or it is a problem? Can anybody help me to make clear this question?
