I am fairly new to coding in general and really new to Xcode (Swift). I understand that I need to register a nib or a class but I don\'t understand \'where or how?\'.
If you defined your cell through the Interface Builder, by placing a cell inside your UICollectionView, or UITableView :
UICollectionView
UITableView
Make sure you binded the cell with an actual class you created, and very important, that you checked "Inherit module from target"
