SnapKit is a DSL to make Auto Layout easy on both iOS and OS X.
import SnapKit class MyViewController: UIViewController { lazy var box = UIView() override func viewDidLoad() { super.viewDidLoad() self.view.addSubview(box) box.snp_makeConstraints { (make) -> Void in make.width.height.equalTo(50) make.center.equalTo(self.view) } } }
