I can't find a way to make Xcode 11.3 show my Objective-C class methods in the Symbol Navigator. Everything else works find, but class methods simply won't show, so I'm wondering whether this is a bug. I tried deleting the contents of the DerivedData directory but it didn't solve the problem.
I observe the same with Swift.
To update the list, you have to do n option-clean build folder.
New Instance methods then appear ; but not class methods.
I tried to use Navigate menu command "Reveal in Symbol Navigator": does not find it for class methods.
What is surprising in objc is that instance methods do appear with - sign.
That would suggest class methods would appear with + sign.
Should file enhancement request.
