This is not about running under the Xcode debugger, but about the appearance of the debug menu while running an application (even without debugger at all).

Using Radare2 rax2 command:

rax2 -S 'DEBUG'

Output:

4445425547

Adding per app setting in preferences (stored in ~/Library/Containers/)

Sample app is TextEdit (CFBundleIdentifier is com.apple.TextEdit):

defaults write com.apple.TextEdit _NS_4445425547 -bool true

Run app:

open -a TextEdit

You'll see bug icon in menu (before Help menu).


Adding global system setting in preferences

defaults write -g _NS_4445425547 -bool true

Reading global value:

defaults read -g _NS_4445425547

Sample output:

The domain/default pair of (kCFPreferencesAnyApplication, _NS_4445425547) does not exist
