How to fix Unknown Class in Interface Builder when using SPM packages

I had a problem few days ago trying to use storyboards from a SPM package. I was unable to instantiate controllers from storyboard, even had the right class name and the right target module.

So… I googled it and I found a lot of posts about this problem.

Unknown class _TtC10MySPModule24ViewController in Interface Builder file.

I tried all methods found on web but nothing worked… Until I found this thread:

Thanks to Karim I fixed my code

• Adding @objc(OBJCViewController) before my actual ViewController definition and…
• Replacing ViewController with OBJCViewController in storyboard.
