CompactAnimation

Compact syntax, making CoreAnimation more writable

You write

letfadeIn=B.fade(by:1).begin(0).duration(1)letscale=B.scale(from:0, to:1).duration(1)letappear=G.combine(fadeIn, scale)letmove=B.move(by:CGPointMake(screenSize.width +50,0)).duration(1).begin(1)letdisappear=S.scale(to:0).begin(5).duration(1)lettimeline=G.combine(appear,move,disappear).duration(6)
return timeline

Instead of

letfadeIn=CABasicAnimation(keyPath:"opacity")
fadeIn.fromValue =0
fadeIn.toValue =1
fadeIn.duration =1
fadeIn.fillMode = kCAFillModeForwards
fadeIn.removedOnCompletion =falseletscaleUp=CASpringAnimation(keyPath:"transform.scale")
scaleUp.fromValue =0
scaleUp.toValue =1
scaleUp.duration =1
scaleUp.fillMode = kCAFillModeForwards
scaleUp.removedOnCompletion =falseletappear=CAAnimationGroup()
appear.animations =[fadeIn, scaleUp]
appear.duration =1
appear.fillMode = kCAFillModeForwards
appear.removedOnCompletion =falseletmove=CABasicAnimation(keyPath:"position")
move.byValue =NSValue(CGPoint:CGPointMake(screenSize.width +50,0))
move.duration =1
move.beginTime =1
move.fillMode = kCAFillModeForwards
move.removedOnCompletion =falseletdisappear=CASpringAnimation(keyPath:"transform.scale")
disappear.toValue =NSValue(CGSize:CGSizeMake(0,0))
disappear.duration =1
disappear.beginTime =5
disappear.fillMode = kCAFillModeForwards
disappear.removedOnCompletion =falseletappIcon1Timeline=CAAnimationGroup()
appIcon1Timeline.animations =[appear, move, disappear]
appIcon1Timeline.duration =6
appIcon1Timeline.fillMode = kCAFillModeForwards
appIcon1Timeline.removedOnCompletion =false
return appIcon1Timeline

Keyframe examples:

letposition=K.move{(config)->()inconfig(keyTime:0.0/6.0).to(CGPointMake(screenSize.width +50,250))config(keyTime:1.5/6.0).to(CGPointMake(screenSize.width +50,250))config(keyTime:2.0/6.0).to(CGPointMake(125,250))config(keyTime:3.0/6.0).to(CGPointMake(125- screenSize.width,250))}.duration(6)

letposition=CAKeyframeAnimation(keyPath:"position")
position.values =[NSValue(CGPoint:CGPointMake(screenSize.width +50,250)),NSValue(CGPoint:CGPointMake(screenSize.width +50,250)),NSValue(CGPoint:CGPointMake(125,250)),NSValue(CGPoint:CGPointMake(125- screenSize.width,250)),]
position.keyTimes =[0,1.5/6.0,2.0/6.0,3.0/6.0,]
position.fillMode = kCAFillModeForwards
position.removedOnCompletion =false
position.duration =6
