How to see the full name of the selected method when filling in Xcode

I am trying to implement a delegate method in Xcode and I see many methods that look very similar as their names / signatures are truncated:

For example, there is no way to distinguish which method is selected and which method is below the selected one, and this is just one example. I have the same problem where a delegate is associated with long method names and I am trying to implement one of its methods. The pop-up menu is meant to be used and is extremely controversial in such cases.

Is there a way to display / distinguish fully qualified method names?
