Implementing UIView in SwiftUI

I am trying to implement a video player in SwiftUI via a UIView following this tutorial: https://medium.com/flawless-app-stories/avplayer-swiftui-b87af6d0553

Unfortunately the video is not displaying, I have AVFoundation imported so I am not sure of the issue. Has anyone found a solution to this?

Here are the classes I created:

class PlayerUIView: UIView {
    private let playerLayer = AVPlayerLayer()
    
    init(frame: CGRect, urlString: String) {
        super.init(frame: frame)
        guard let url = URL(string: urlString) else {
            return
        }
        let player = AVPlayer(url: url)
        player.play()
    
        playerLayer.player = player
        layer.addSublayer(playerLayer)
     }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
    }
    
     override func layoutSubviews() {
        super.layoutSubviews()
        playerLayer.frame = bounds
     }
}

struct VideoPlayerUIView: UIViewRepresentable {
    
    var frame: CGRect
    var urlString: String
    
    func makeUIView(context: Context) -> some UIView {
        return PlayerUIView(frame: self.frame, urlString: self.urlString)
    }
    
    func updateUIView(_ uiView: UIViewType, context: Context) {
        
    }
}

Here I how I am using the implementation in SwiftUI:

var body: some View {
      Text("Videos")
      VideoPlayerUIView(frame: CGRect(x: 0, y: 0, width: 400, height: 300), urlString: urlString)
}

This was the output (no video) enter image description here

You did everything right here.

The only thing that is causing error is how you are process the URL.

Try initialising the player like this instead

     let player = AVPlayer(url: Bundle.main.url(forResource: urlString, withExtension: "mp4")!)

Change the extension according to the format you are using. Remember, here I am force wrapping the optional. So, if you give a wrong urlString or have a video extension other than mp4, the app will crash
