“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

This worked for me:

1. Perform 'Clean build folder'
   (press and hold the 'option' key and go to the "Product" menu to access it.
2. Perform a simple "Clean" (CMD-SHIFT-K) from the "Product" menu.
3. Build the project to let Xcode compile the files. Also, let it index files if necessary.

On a side note, I am not sure if this helped but I also deleted the Derived data before performing the above steps (Xcode preferences > Locations)
