//Objective c - (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {         return CGSizeMake((collectionView.frame.size.width/3)-20, 100);     }  // Swift 2.0  func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {     return CGSizeMake((collectionView.frame.size.width / 3) - 20, 100) }  // Swift 3.0 override func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {     return CGSize(width: CGFloat((collectionView.frame.size.width / 3) - 20), height: CGFloat(100)) }
