Initially I read you couldn't experiment with touches or gestures in a playground. Then I found that touchesMoved or a tap gesture would react. However, I now am testing a UIPinchGestureRecognizer. There isn't the feature that lets you simulate two fingers with the alt key in the playground. Are you telling me I have to create an Xcode project and compile and run for each iteration simply because its a pinch and not a tap?
