I'm attempting to simply pass the video link inside the json to the navigation menu... my brain is fried as I'm lost in why I can't do this view the navigation link protocol. import SwiftUI import AVKit struct MainDetail: View {          var json: Main         private let player = AVPlayer(url: URL(string: item.interactive))        var body: some View {      VideoPlayer(player: player)             .onAppear() {                 // Start the player going, otherwise controls don't appear                 player.play()             }             .onDisappear() {                 // Stop the player when the view disappears                 player.pause()             }    } } this returns a "Cannot find 'item' in scope" despite being declared back on the main content view. the intended action is loading the "interactive" link (m3u8 file) in a player view when clicked on. I apologize for not understanding what's going on here.

I've been watching various tutorials and have managed to come up with the following code: import SwiftUI import AVKit struct ContentView: View {     @State private var wolData = [Main]()          var body: some View {                  NavigationView{List(wolData, id: \.id) { item in             NavigationLink(destination: MainDetail(json: item)) {                                  HStack() {                     Text(item.name)                         .font(.headline)                     Text(item.date)                         .font(.footnote)                     if #available(iOS 15.0, *) {                         AsyncImage(url: URL(string: item.thumbnail))                         { image in                             image                                 .resizable()                                 .scaledToFill()                         } placeholder: {                             Color.purple.opacity(0.1)                         }                         .frame(width: 20, height: 20)                     } else {                         // Fallback on earlier versions                     }                 }                              }                      }.onAppear(perform: loadData)}              }           } extension ContentView {     func loadData() {                  guard let url = URL(string: "https://wolvideos.firebaseapp.com/Simple.json") else {             return         }                  let request = URLRequest(url: url)         URLSession.shared.dataTask(with: request) { data, response, error in                          if let data = data {                 if let response_obj = try? JSONDecoder().decode([Main].self, from: data) {                                          DispatchQueue.main.async {                         self.wolData = response_obj                     }                 }             }                      }.resume()     } } struct ContentView_Previews: PreviewProvider {     static var previews: some View {         ContentView()     } } import Foundation struct Main: Decodable {     var id: Int     var name: String     var interactive: String     var thumbnail: String     var date: String     var videolink: String     var sharelink: String } import SwiftUI import AVKit struct MainDetail: View {     var json: Main    private let player = AVPlayer(url: URL(string: "https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8")!)        var body: some View {      VideoPlayer(player: player)             .onAppear() {                 // Start the player going, otherwise controls don't appear                 player.play()             }             .onDisappear() {                 // Stop the player when the view disappears                 player.pause()             }    } } Now that I've shared that, the intent is to when the user clicks an option load the corresponding video (from the json not the current test file) via HLS in a default player (like the one in safari)... should I be going about this in a different way? I'm starting to think committing to SwiftUI is a mistake.

This video session is essentially a consumer facing video, there isn't even a single line of code shown. VideoPlayer(player: player) doesn't give the shown "new features" by default, an example / implementation should be expected of a WWDC session.

I've followed several tutorials and nothing works or is remotely simple. can anyone perhaps link a json tutorial that can load the following in a "SWIFT UI" format? { "id": 182, "name": "message 2048", "interactive": "https://wolvideos.firebaseapp.com/Test1.mp4", "thumbnail": "https://wolvideos.firebaseapp.com/back.jpg", "date": "April 1", "videolink": "https://player.vimeo.com/external/656370948.m3u8?s=e50ca2b440798886646ba88a07e9c46a90c9df11", "sharelink": "https://youtu.be/n7YjxFCyDNQ" }, { "id": 180, "name": "Title 4", "interactive": "https://wolvideos.firebaseapp.com/Test2.mp4", "thumbnail": "https://wolvideos.firebaseapp.com/back.jpg", "date": "April 2", "videolink": "https://player.vimeo.com/external/653500077.m3u8?s=96c687bef62bfd01ea195e4113e197ebd8d09143", "sharelink": "https://youtu.be/n7YjxFCyDNQ" }, { "id": 172, "name": "Titil 20203", "interactive": "https://wolvideos.firebaseapp.com/Test1.mp4", "thumbnail": "https://wolvideos.firebaseapp.com/back.jpg", "date": "April 1", "videolink": "https://player.vimeo.com/external/656370948.m3u8?s=e50ca2b440798886646ba88a07e9c46a90c9df11", "sharelink": "https://youtu.be/n7YjxFCyDNQ" }, { "id": 171, "name": "Title 20part2", "interactive": "https://wolvideos.firebaseapp.com/Test2.mp4", "thumbnail": "https://wolvideos.firebaseapp.com/back.jpg", "date": "April 2", "videolink": "https://player.vimeo.com/external/653500077.m3u8?s=96c687bef62bfd01ea195e4113e197ebd8d09143", "sharelink": "https://youtu.be/n7YjxFCyDNQ" }, { "id": 170, "name": "Title 2021", "interactive": "https://wolvideos.firebaseapp.com/Test1.mp4", "thumbnail": "https://wolvideos.firebaseapp.com/back.jpg", "date": "April 1", "videolink": "https://player.vimeo.com/external/656370948.m3u8?s=e50ca2b440798886646ba88a07e9c46a90c9df11", "sharelink": "https://youtu.be/n7YjxFCyDNQ" }, { "id": 169, "name": "Title 2020", "interactive": "https://wolvideos.firebaseapp.com/Test2.mp4", "thumbnail": "https://wolvideos.firebaseapp.com/back.jpg", "date": "April 2", "videolink": "https://player.vimeo.com/external/653500077.m3u8?s=96c687bef62bfd01ea195e4113e197ebd8d09143", "sharelink": "https://youtu.be/n7YjxFCyDNQ" } ] https://wolvideos.firebaseapp.com/Simple.json

it's infuriating that it sometimes only takes 2 minuets and then takes hours on other devices. knowing how long it's going to take would actually give us information to make adjustments. I'm. asking this one to see how many other developers would also like this feature, and to see if anyone knows of an add-on or such.

I'm using this documentation as my base https://developer.apple.com/tutorials/swiftui/building-lists-and-navigation I'm failing to understand how I would simply adapt the app to load the json remotely import Foundation var landmarks: [Landmark] = load("landmarkData.json") func load<T: Decodable>(_ filename: String) -> T {     let data: Data     guard let file = Bundle.main.url(forResource: filename, withExtension: nil)         else {             fatalError("Couldn't find \(filename) in main bundle.")     }     do {         data = try Data(contentsOf: file)     } catch {         fatalError("Couldn't load \(filename) from main snippet from Model data.swift the only example I've found is included below, however it's using an entirely different setup and does not use a detail view. import SwiftUI import Combine struct ContentView: View { @ObservedObject var fetcher = MovieFetcher() var body: some View {     VStack {         List(fetcher.movies) { movie in             VStack (alignment: .leading) {                 Text(movie.name)                 Image(movie.thumbnail)                 Text(movie.released)                     .font(.system(size: 11))                     .foregroundColor(Color.gray)             }         }     } } } public class MovieFetcher: ObservableObject { @Published var movies = [Movie]() init(){     load() } func load() {     let url = URL(string: "https://wolvideos.web.app/videos.js")!     URLSession.shared.dataTask(with: url) {(data,response,error) in         do {             if let d = data {                 let decodedLists = try JSONDecoder().decode([Movie].self, from: d)                 DispatchQueue.main.async {                     self.movies = decodedLists                 }             }else {                 print("No Data")             }         } catch {             print ("Error")         }              }.resume()       } } struct Movie: Codable, Identifiable { public var id: Int public var name: String public var thumbnail: String public var released: String enum CodingKeys: String, CodingKey {        case id = "id"        case name = "name"        case thumbnail = "thumbnail"        case released = "description"     } } struct ContentView_Previews: PreviewProvider { static var previews: some View {     ContentView() } } If possible can someone explain how and the best way to load a json file and then let the app format it into detail views?

I'm using sidecar as a second display and have "displays as separate windows off" and restarted! Why does apple insist on clipping the windows too locations I did not specify even using Option key still clips the window to one window not spanning both windows! when using a PC this is very simple on MacOS it seems Apple has made it a pain to do something so simple!

im having so much trouble trying to figure pout how I can get a SwiftUI button to link to a different SwiftUI file / view that is giving me so much trouble. First View - https://developer.apple.com/forums/content/attachment/1edea652-6345-4032-8bf1-04b41825c4db Second View - https://developer.apple.com/forums/content/attachment/85511659-3631-4fdc-b30f-6f0e94e81a2e ' Attempted solution - https://developer.apple.com/forums/content/attachment/1d83eb4b-6fbe-481b-ad94-e36ad283760f This is the Code I was attempting to bridge them with but I keep ending up with many different errors. So what am I not getting... there has to be a way to do this if not then what's the point of using SwiftUI?

How can I get SwiftUI to load 8 images horizontally but if the third image happens to go off screen it puts it in a Vstack underneath the 1st image with the same padding... and if three can fit on the screen it does the same to the 6th. I can not find anyway to do this! This should be simple and is easy to achieve using UIkit.

I'm sick of this I can't figure out why Apple makes its so hard to get an app uploaded anymore... I have all the stupid icon files in the app and I'm still getting these errors.
