I just upgraded Xcode to 5.0. I'm still fairly new to cocoa so I hope I'm overlooking something basic. Basically I can't get Xcode to see the custom classes that I want to use as parent classes for view controllers. Originally I wanted to create a custom class for a tableview controller but to simplify the problem I tried it with regular viewcontrollers, but that doesnt work either.
What I do:
The class simply does not appear in the drop down, and I cant type it myself either. Many other threats reporting the same problem suggest closing/reopening the project and Xcode but that doesnt work either for me.
When you are in the storyboard, Interface Builder of Xcode, make sure you click on black colored bar under the view:
This will select the view controller (not the view) in the storyboard. Notice how the whole scene has a blue border around it. Once this is selected, you can set the class of the view controller in the Identity Inspector.
