Manual

Add FlickToDismissViewController.swift to your project in Xcode.

Usage

Interface Builder

1. Drag a new UIViewController object onto your storyboard.
2. Set the class to FlickToDismissViewController.
3. Drag a UIView object onto the View Controller.
4. Add any necessary constraints.
5. Connect the flickableView outlet to the UIView in the Connections inspector.
6. Job done.

Programatically

let viewToFlick = UIView(frame: CGRect(x: 0, y: 0, width: 280, height: 300))
viewToFlick.backgroundColor = .whiteColor()
// Optional - See FlickToDismissOption for available options.
let options: [FlickToDismissOption] = [
.Animation(.Scale),
.BackgroundColor(UIColor(white: 0.0, alpha: 0.8))
]
let vc = FlickToDismissViewController(flickableView: viewToFlick, options: options)
vc.modalTransitionStyle = .CrossDissolve
vc.modalPresentationStyle = .OverFullScreen
presentViewController(vc, animated: true, completion: nil)

Hint - Subclassing UIView

Since Auto Layout sizes views according to their frames, it incorrectly assumes it has a larger space to lay things out when a view is rotated. To correct this we need to supply the method alignmentRectForFrame() in the view subclass:

override func alignmentRectForFrame(frame: CGRect) -> CGRect {
    return bounds
}
