“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

Product > Clean (Command - Shift - K) fixed it for me!

Answer 2

Just need to clean and re-build the project.

Answer 3

I tried EVERYTHING!

Make sure the class name of your UIViewController does not contain the word "Test"

Answer 4

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

Answer 5

In case anyone is still frustrated by this, there's a trick to get things working.

What I do is manually enter an outlet into my class, for example: @IBOutlet weak var someView: UIView!, and drag from the code to the view in IB or storyboard. After this, I am able to drag from IB / Storyboard to my class to make connections, assistant editors recognizes the class in "Automatic", etc...

Works every time.

Answer 6

If people try the above and things are still not working, the strange trick that worked for me was adding the outlet in a chunk of whitespace. It works if there are no other lines directly above or below the line you're adding. Strange, but it worked!
