Animation using array of images in sequence in swift

iOS에서 간단히 애니메이션을 구현하는 방법

// swift
        let animationImages:[AnyObject] = [UIImage(named: "loading_outlink_01")!, UIImage(named: "loading_outlink_02")!, UIImage(named: "loading_outlink_03")!, UIImage(named: "loading_outlink_04")!]
        loadingImageView.animationImages = animationImages
        loadingImageView.animationDuration = 1.5
        loadingImageView.animationRepeatCount = 0
        loadingImageView.startAnimating()
        self.addSubview(loadingImageView)
