ios - "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 find any information for class named ViewController.

This happens with custom classes as well. I've tried methods such as:

• Deleting the delegate data.
• Removing and re-adding the classes.
• Restarting Xcode.
• Reinstalling Xcode.

I can't ctrl-drag to create connections in any of my projects no matter what the class is. The same problem happens with a brand-new template application. If I type in the code manually and then ctrl-drag, I can make a working connection, but I can't add it automatically. Nothing I've been able to find so far on the Internet has helped. Any pointers?

Answer 1

What solved this issue for me was actually deleting the class from the project.

Steps:

1. In the project file explorer (left panel) find the class and right click -> Delete
2. Remove reference (do not move to trash as you will lose the class for good)
3. Right click on the folder that contained the class -> Add files to ...
4. Find the class you just deleted in the file system

This seems to force Xcode to link the class back into the storyboard.

Note: for me the following did not work:

• Closing Xcode
• Cleaning the project
• Deleting the class name from the storyboard and re-entering it

I think this is a bug on Apple's part
