import UIKit
import Lottie

// Note: All graphics are included in json animation file
//       Also the file name matters. You must use the same json file name when loading.

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let animationView = AnimationView(name: "39784-check-mark")

        animationView.frame = CGRect(x: 0, y: 0, width: 400, height: 400)
        animationView.center = self.view.center
        animationView.contentMode = .scaleAspectFill
        animationView.loopMode = .loop
        animationView.animationSpeed = 0.5

        view.addSubview(animationView)

        animationView.play()
