Hi! So im coding and I’m about to lauch the app via the simulator but I’t crashes and I get this error message.

Thread 1: “-[UIViewController collectionView:numberOfItemsInSection:]: unrecognized selector sent to instance 0x130f0a530”

And I've located the bug but I don’t understand it. The bug happens when I connect the collection view from the mainstory.board to the view controller. Specifically when I add the dataSource from the collection view to the view controller, how can I fix this, cause without this I just get a blanc screen on the sim?

I'd happily share the project if that helps solving the issue!
