Answer 1

Swift 3

If you are using swift 3, use this method:

    func collectionView(_ collectionView: UICollectionView,
                        layout collectionViewLayout: UICollectionViewLayout,
                        sizeForItemAt indexPath: IndexPath) -> CGSize {

    }

Notice the changes:

1. add _ before collectionView in the method name
2. NSIndexPath changes to IndexPath
