Answer 1

add this code to viewDidLoad. change height according to you.

try this!

if let layout = collectionView?.collectionViewLayout as? UICollectionViewFlowLayout{
        layout.minimumLineSpacing = 10
        layout.minimumInteritemSpacing = 10
        layout.sectionInset = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 10)
        let size = CGSize(width:(collectionView!.bounds.width-30)/2, height: 250)
        layout.itemSize = size
}
