Answer 1

This is the simplest solution.

Your UIViewController should implement UICollectionViewDelegateFlowLayout. Then the function below needs to be implemented on your UIviewController.

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

    let width = self.collectionView.frame.size.width / 2;


    return CGSize(width: width, height: 230)

}

Furthermore, you can adjust each cell's spacing value on your storyboard. Click collectionView then see the size inspector.
