“Could not find any information for class named ViewController”

Question

This bug has been driving me nuts since I started using Xcode (4.6.3). Whenever I try to link a Storyboard item to my code, I get the error:

Could not

Answer 1

I tried everything and it didn't work, so for me what worked is:

• Clean Build folder and project.
• Open Projects (Window -> Projects)
• Find your project on the list and delete the Derived Data
• Close Xcode
• Restart computer (without choosing to reopen windows that are open)
• run Xcode
• Work!

All my view controllers were not being recognized, so deleting all files and re-adding was not an option as this is a big project.
