Funny demo's gif(s)

Chainable

1. Common
   

for (index,line) in leftLines.enumerate() {
    let delay = Double(index) * 0.2
    
    line.moveX(200).duration(2).easing(.SwiftOut).delay(delay)
        .then().moveX(-200).rotateY(1.43).easing(.SwiftOut)
        .makeColor(UIColor.greenColor()).repeatCount(100)
        .autoreverses().duration(2).animate()
 }
        
 for (index,line) in rightLines.enumerate() {
    let delay = Double(index) * 0.2
    
    line.moveX(-200).duration(2).easing(.SwiftOut).delay(delay)
        .then().moveX(200).rotateY(1.43).easing(.SwiftOut)
        .makeColor(UIColor.purpleColor()).repeatCount(100)
        .autoreverses().duration(2).animate()
 }

2. every step completion observable
   

animateView.makeSize(CGSizeMake(50, 150)).snap(0.3).completion({
                print("First step")
            })
            .then().moveX(-100).moveY(-50).anchorPoint(CGPointMake(1, 1)).duration(1).completion({
                print("Second step!")
            })
            .then().rotate(CGFloat(M_PI)).attachment(0.3, frequency: 0.8).completion({
                print("Third step!")
            })
            .then().moveY(500).completion({
                print("last step, all completion")
            })
            .animate()
