AnimationSequencer

Very simple and scalable UIView animation extension without nested completion closures. It uses standard iOS api but wraps around a nicer look.

Usally we make animations using system animate() method and completion block, but in my experience it's not scalable, very hard to read and it's hard to remove or add a new animation according to design specifications.

Minimum Requirements

• iOS 8.0+
• Swift 5.1+

Usage

From this nested, ugly, nested completion.

UIView.animate(withDuration: 1.0, delay: 2.0, animations: {
    
    square.center.x += 100
    square.center.y += 100
    
}) { (finished) in
    UIView.animate(withDuration: 0.3, animations: {
        
        square.center.x = self.view.center.x
        square.center.y = self.view.center.y
        
    }) { (finished) in
        UIView.animate(withDuration: 0.3, animations: {
            
            square.alpha = 0
            
        }) { (finished) in

        }
    }
}

To pure clean, couple lines of code

square.animate([
    ASAction.move(byX: 100, y: 100, duration: 1.0).delayedFor(2.0),
    ASAction.move(centerToX: self.view.center.x, y: self.view.center.y),
    ASAction.fadeOut()
])

Installation

CocoaPods

$ [sudo] gem install cocoapods

Go to the directory of your Xcode project, and Create and Edit your Podfile and add the lib:

$ cd /path/to/MyProject
