Xcode, can't find my class which I had created

I've had the same problem. Quitting and opening Xcode will make the Class show up in the list.

edit: I've also recently found pasting the Class name will work in 5.02 Xcode.

I had the same problem. But I discovered that I was clicking inside the "window of storyboard" and was selecting a view, so with no viewController related to. My solution was: to click inside the owner, or the viewController from the left list, and then change the custom class.

There Are multiple ways....
