AutoLayoutをSwiftで簡潔に記述できるSnappyを試してみた ref: http://qiita.com/morizotter/items/0856e5614486df65eee6

import UIKit
import Snappy

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // FULL SCREEN VIEW [BLUE]

        let blueView = UIView()
        blueView.backgroundColor = UIColor.blueColor()
        self.view.addSubview(blueView)

        blueView.snp_makeConstraints { make in
            make.edges.equalTo(self.view)
            return
        }

        // PADDING ALL EDGES [ORANGE]

        let orangeView = UIView()
        orangeView.backgroundColor = UIColor.orangeColor()
        self.view.addSubview(orangeView)

        let orangeViewPadding = UIEdgeInsetsMake(10, 10, 10, 10)
        orangeView.snp_makeConstraints { make in
            make.edges.equalTo(self.view).with.insets(orangeViewPadding)
            return
        }

        // VIEW ON PADDING VIEW [GREEN]

        let greenView = UIView()
        greenView.backgroundColor = UIColor.greenColor()
        orangeView.addSubview(greenView)

        let greenViewPadding = UIEdgeInsetsMake(0.0, 0.0, 150.0, 10.0)
        greenView.snp_makeConstraints { make in
            make.top.equalTo(orangeView.snp_top).with.offset(greenViewPadding.top)
            make.left.equalTo(orangeView.snp_left).with.offset(greenViewPadding.left)
            make.bottom.equalTo(orangeView.snp_bottom).with.offset(-greenViewPadding.bottom)
            make.right.equalTo(orangeView.snp_right).with.offset(-greenViewPadding.right)
            return
        }
    }
}
