Incomplete implementation warning

Question

Is there a way of having Xcode tell me what function is not implemented correctly that is triggering its "incomplete implementation" warning?

Answer 1

Sometimes method names are not shown in the in-code warnings. In that case:

Go to the Issue navigator (the warning sign in the left pane), expand the warning, click on "Method declared here".

First, click the little arrow (1), then click one of the method names (2).

Answer 2

If you click on the warning sign that Xcode displays at the very end of the file which is missing a method definition, you will see an additional message telling you which method it is.
