How can I get started building a simple app that loops video?

To get started building a simple app that loops video, you can leverage the AVFoundation framework, which is designed to handle video playback and recording. Here are some steps and resources to help you:

1. Set Up Your Project:

   • Create a new SwiftUI project in Xcode.
   • Import the necessary frameworks, such as AVFoundation.

2. Create a Video Player:

   • Use AVPlayer and AVPlayerViewController to handle video playback.
   • Set up the player to loop the video by observing the end of the playback and restarting it.

3. Sample Code:

   import SwiftUI
   import AVKit
   
   struct VideoPlayerView: View {
       private let player: AVPlayer
   
       init(videoURL: URL) {
           self.player = AVPlayer(url: videoURL)
           NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: player.currentItem, queue: .main) { _ in
               self.player.seek(to: .zero)
               self.player.play()
           }
       }
   
       var body: some View {
           VideoPlayer(player: player)
               .onAppear {
                   player.play()
               }
               .onDisappear {
                   player.pause()
               }
       }
   }
   
   struct ContentView: View {
       var body: some View {
           VideoPlayerView(videoURL: URL(string: "https://example.com/video.mp4")!)
       }
   }
