how to pass parameter in init method of UIView?

Let me know if i have made any mistake don't downcast the question.

here is the problem i am trying to play a video and following is code

import UIKit
import AVFoundation

// custom UIView to display frame for avplayer

class VideoPlayerView: UIView {

    let urlString String?

    override init(frame: CGRect) {
        super.init(frame: frame)

        backgroundColor = .blackColor()

        //static url for video

        urlString = "https://firebasestorage.googleapis.com/v0/b/gameofchats-762ca.appspot.com/o/message_movies%2F12323439-9729-4941-BA07-2BAE970967C7.mov?alt=media&token=3e37a093-3bc8-410f-84d3-38332af9c726"
        if let url = NSURL(string: urlString) {
            let player = AVPlayer(URL: url)

            let playerLayer = AVPlayerLayer(player: player)
            self.layer.addSublayer(playerLayer)
            playerLayer.frame = self.frame

            player.play()
        }

    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

// view controller to launch video player

class VideoPlayerController: UIViewController {

    var message: Messages?{
        didSet{

        }
    }


    let overlayView: UIView = {
        let view = UIView()
        view.isUserInteractionEnabled = true
        view.backgroundColor = UIColor(white: 0, alpha: 0.5)
        return view
    }()


    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .black

                let height = view.frame.width * 9 / 16
        let videoPlayerFrame = CGRect(x: 0, y: 0, width: view.frame.width, height: height)

        let videoPlayerView = VideoContainerView(frame: videoPlayerFrame)
        view.addSubview(videoPlayerView)

        videoPlayerView.center = view.center

    }

in the init method of VideoPlayerView i have used static url of video for urlString property which is playing fine. i want to set urlString property from my videoPlayerController class how i can do that ? because when i initialize 

let view = VideoPlayerView(frame:frame) // this code will call init method before i can set the urlString property.

anyone have idea how to do that. please help. thank you in advance for any suggestions.

Just make other initializer with needed parameters and call it.

convenience init(frame: CGRect, urlString: String) {
    self.init(frame: frame)
    //make here what you want
}
