// running a custom block. not perfect right now, but it works.
let custom = CFAAction.customActionWithDuration(0.1, actionBlock: { layer, elapsedTime in
    if(elapsedTime == 0.1) {
        print("Executing custom code in between steps!")

let color = CFAAction.colorize(fromValue: UIColor.blueColor(), toValue: UIColor.redColor(), time: 2.5, curveType: CurveType.CurveTypeLinear, easeType: EaseType.EaseTypeInOut)

let sequence = CFAAction.sequence([ fade, CFAAction.waitForDuration(1.0), custom, group, color ])

foo.layer.runAction(sequence) {
    print("Animation is complete!")
