Xcode 4 Inspector Panel tells me “No Choice” no matter what

Question

I have a window, label, button and NSObject.

The first thing I want to do is change the NSObject class to my user controller.

The fact is that I can’t choose it. Regardless of the object that I select, the inspector panel says "No choice." What for? I am puzzled.

Answer 3

I just had to close the editor’s assistant and the debug area, and then it magically appeared. If you do not have an open assistant editor, all you have to do is open it and then close it again. That should fix too.

If you don’t know what the editor’s assistant is, I highlighted it in red:

Answer 4

For me, I had a bottom, the debugger stretched to the top. It said "no choice." By double-clicking the hide / open bottom debugger, you can return the main component again.
