I am having an issue when editing Storyboard views. When I click on a ViewController and attempt to assign it a custom class, nothing appears except UIViewController.
I have ensured the .m files appear in Compile Sources.
Here is the strange thing: If I store the project in my users /Documents/ directory, this issue happens randomly to all projects saved in there. If I copy the project folder to my Desktop and open it in XCode, my custom classes show up. I have the same issue on my Macbook as well.
