Assuming you know the desired cell height, conform to UICollectionViewDelegateFlowLayout:

class Class_MyUIViewClass: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout {

and implement sizeForItemAtIndexPath:

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
    let desirednumberOfCollumns: CGFloat = 2
    let width = collectionView.frame.width / desirednumberOfCollumns
    return CGSize(width, yourHeight)
}

You can use sizeForItemAt method of UICollectionView to manage cell size of it

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    let screenWidth = UIScreen.main.fixedCoordinateSpace.bounds.width
    return CGSize(width: screenWidth/2, height: yourHeight)
}

Also confirms to UICollectionViewDelegateFlowLayout
