SequenceAnimator

A wrapper for UIView animation which makes it easy to write sequences of animations

So instead of writing:

    UIView.animate(withDuration: 0.5, animations: {
        //Some animation
    }) { done in
        UIView.animate(withDuration: 0.5, animations: {
            //Do another animation after the first...
        }, completion: ...)
    }

You write:

    SequenceAnimator.animate(0.5) {
        //Some animation
    }.animate(0.5) {
        //Another animation after the first
    }.done {
        //We're done
    }

You can intersperse done blocks throughout the chained animations and also use delays

Take a look the included demo app

Which includes a comparison of implicit UIView animation syntax with SequenceAnimator
