Scale images with Pinch Gesture in iOS with Swift

Swift Version: unspecified

The UIKit framework provides predefined gesture recognizers that detect common gestures. Gesture recognizers are objects that you attach to a view, which allows the view to respond to actions. In this tutorial we will display an image, which can be scaled up and down with the pinch gesture. This tutorial is written in Swift so you will need Xcode 6. It can be downloaded at Apple's developer portal.
