Cell?.backgroundColor = UIColor .orangeColor()

Answer 1

Convert this code to swift you will get result:

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{

UICollectionViewCell *cell = [collectionView cellForItemAtIndexPath:indexPath];
    cell.backgroundColor = [UIColor magentaColor];

}

-(void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath
{

UICollectionViewCell *cell = [collectionView cellForItemAtIndexPath:indexPath];
    cell.backgroundColor = [UIColor greenColor];

}

Answer 2

This is exactly what you need. Setting it inside cellForItemAtIndexPath, you don't need to care when is deselected for doing it manually.

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    //...
        var bgColorView = UIView()
        bgColorView.backgroundColor = UIColor.whiteColor()
        cell.selectedBackgroundView = bgColorView

        return cell
    }
