Lesson 5 of the MatchGame

App Development

Hello, I have just finished Lesson 5 of the MatchGame series. Build succeeds and the card numbers are generated but the cards do not show in the simulator and I get a long list of errors starting with the following

2019-11-13 21:11:23.097564+0900 MatchGame[6628:545629] [Storyboard] Unknown class CardCollectionViewCell in Interface Builder file.

2019-11-13 21:11:23.110432+0900 MatchGame[6628:545629] *** Terminating app due to uncaught exception ‘NSUnknownKeyException’, reason: '[<UICollectionViewCell 0x7f9f4e7023b0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key backImageView.'

Ok I figured it out I didn’t have ‘inherit module from target’ ticked Whatever that means

I am having the same issue, it will be great if you could elaborate what exactly you did.

when creating your .swift file it should be a subclass of UICollectionViewCell, you should also set this as the custom class of the cell in your storyboard
