Same issue here! Solid pink screen!!! Works on iOS 17 but not on iOS 18+ (tested also on the latest iOS 18.2.1) Trying to reproduce with this simple snippet: struct ContentView : View { private let player = AVPlayer() var body: some View { RealityView { content in let model = Entity() let mesh = MeshResource.generatePlane(width: 1, height: 1) let material = VideoMaterial(avPlayer: player) model.components.set(ModelComponent(mesh: mesh, materials: [material])) model.position = [0, 1, -2] content.add(model) content.camera = .spatialTracking } .edgesIgnoringSafeArea(.all) .onAppear() { Task { let videoURL = URL(string: "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4") let playerItem = AVPlayerItem(url: videoURL!) // let videoAssetTrack = try await playerItem.asset.loadTracks(withMediaType: .video) // try await videoAssetTrack.first!.load(.naturalSize) // Tell the player to load and play player.replaceCurrentItem(with: playerItem) player.play() } } } } If you argue that i'm using http instead of https, i tryed both (also with "App Transport Security Settings" -> "Allow Arbitrary Loads": yes into info.plist) Got a lot of warnings (i suppose that some shader or some material, as VideoMaterial, are missing): Error creating the CFMessagePort needed to communicate with PPT.
