You must have to implement Size for item method and need to confirm to UICollectionViewDelegateFlowLayout .

As every iPhone has different width you can not set to static width.

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        return CGSize(width: collectionView.frame.width, height: 150)
    }
