My solution in Swift 3 cell line spacing like in Instagram:

lazy var collectionView: UICollectionView = {
    let layout = UICollectionViewFlowLayout()
    let cv = UICollectionView(frame: .zero, collectionViewLayout: layout)
    cv.backgroundColor = UIColor.rgb(red: 227, green: 227, blue: 227)
    cv.showsVerticalScrollIndicator = false
    layout.scrollDirection = .vertical
    layout.minimumLineSpacing = 1
    layout.minimumInteritemSpacing = 1
    return cv
}()

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

    switch UIDevice.current.modelName {
    case "iPhone 4":
        return CGSize(width: 106, height: 106)
    case "iPhone 5":
        return CGSize(width: 106, height: 106)
    case "iPhone 6,7":
        return CGSize(width: 124, height: 124)
    case "iPhone Plus":
        return CGSize(width: 137, height: 137)
    default:
        return CGSize(width: frame.width / 3, height: frame.width / 3)
    }
}
