Download Video using Alamofire and then Play on AV player

Question

I have Used Following Code to Download Video from the URL . It is working fine for Downloading it the Video.

func downloadVideo(){

    Alamofire.request("https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4").downloadProgress(closure:{ (progress) in
    print(progress.fractionCompleted)
    self.progressView.progress = Float(progress.fractionCompleted)

    }).responseData{ (response) in
       print(response.result)
       print(response.result.value!)
       print(response.result.description)

        if let data = response.result.value {
            let obj = String(data: data, encoding: .utf8)
            let player = AVPlayer(url: URL(string: obj!)!)
            self.playerController.player = player
            self.addChildViewController(self.playerController)
            self.view.addSubview(self.playerController.view)
            self.playerController.view.frame = self.view.frame
            player.play()

        }

    }

But I want to Play this Video in AVPlayer

It Would be good if anyone Can suggest some another Code For downloading video with Progress Bar and then Playing it in Swift 3.0.

Afters Hours of Searching for this stuff

I came up With an easy and reliable way of Converting the NSData in URL so that it can be played by AVPlayer

func downloadVideo(){

    Alamofire.request("https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4").downloadProgress(closure : { (progress) in
    print(progress.fractionCompleted)
    self.progressView.progress = Float(progress.fractionCompleted)
    }).responseData{ (response) in
       print(response)
       print(response.result.value!)
       print(response.result.description)
        if let data = response.result.value {

            let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
            let videoURL = documentsURL.appendingPathComponent("video.mp4")
            do {
                try data.write(to: videoURL)
                } catch {
                print("Something went wrong!")
            }
            print(videoURL)
            let player = AVPlayer(url: videoURL as URL)
            self.playerController.player = player
            self.addChildViewController(self.playerController)
            self.view.addSubview(self.playerController.view)
            self.playerController.view.frame = self.view.frame
            player.play()
        }
    }
}

You Can Use this Following Piece of Code to convert that

if let data = response.result.value {

            let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
            let videoURL = documentsURL.appendingPathComponent("video.mp4")
            do {
                try data.write(to: videoURL) // Pass this videoURL to AVPlayer after Downloading Video it will be played.
                } catch {
                print("Something went wrong!")
            }
            print(videoURL)
