I have an app that has been using the following code to down load audio files: if let url = URL(string: episode.fetchPath()) { var request = URLRequest(url: url) request.httpMethod = "get" let task = session.downloadTask(with: request) And then the following completionHandler code: func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL) { try FileManager.default.moveItem(at: location, to: localUrl) In the spirit of modernization, I'm trying to update this code to use async await: var request = URLRequest(url: url) request.httpMethod = "get" let (data, response) = try await URLSession.shared.data(for: request) try data.write(to: localUrl, options: [.atomicWrite, .completeFileProtection]) Both these code paths use the same url value. Both return the same Data blobs (they return the same hash value) Unfortunately the second code path (using await) introduces a problem. When the audio is playing and the iPhone goes to sleep, after 15 seconds, the audio stops. This problem does not occur when running the first code (using the didFinish completion handler) Same data, stored in the same URL, but using different URLSession calls. I would like to use async/await and not have to experience the audio ending after just 15 seconds of the device screen being asleep. any guidance greatly appreciated.

I've implemented func urlSession(_ session: URLSession, task: URLSessionTask, willPerformHTTPRedirection response: HTTPURLResponse, newRequest request: URLRequest, completionHandler: @escaping (URLRequest?) -> Void) and func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didWriteData bytesWritten: Int64, totalBytesWritten: Int64, totalBytesExpectedToWrite: Int64) I've put a breakpoint in each but the BP in willPerformHTTPRedirection never fires. When the didWriteData fires and I inspect downloadTask.originalRequest I see my original request URL When I inspect downloadTask.currentRequest the returned request contains a different URL. I'm the farthest thing from an HTTP wizard, but I had thought when originalRequest differs from currentRequest there had been some sort of server-side 'redirection'. Is there a way for my code to receive a callback when something like this happens? NOTE: my download code works fine, I'm just hoping to detect the case when currentRequest changes. any/all guidance greatly appreciated on the off chance it helps, are are my original and current request values: (lldb) po downloadTask.originalRequest ▿ Optional<URLRequest> ▿ some : https://audio.listennotes.com/e/p/c524803c1a90412f922948274ecc3625/ (lldb) po downloadTask.currentRequest ▿ Optional<URLRequest> ▿ some : https://26973.mc.tritondigital.com:443/OMNY_HAPPIERWITHGRETCHENRUBIN_PODCAST_P/media-session/76cfceb2-1801-4570-b830-ded57611a9cf/d/clips/796469f9-ea34-46a2-8776-ad0f015d6beb/e1b22d0b-6974-4bb8-81ba-b2480119983c/2f35a8ca-b982-44e9-8122-b3dc000ae0e1/audio/direct/t1769587393/Ep_571_Want_to_Join_Us_for_a_No-Spend_February_Plus_a_Better_Word_for_Squats.mp3?t=1769587393&in_playlist=751ada7f-ded3-44b9-bfb8-b2480119985b&utm_source=Podcast

As the title suggests, I have a class marked with @Observable. Within the class I have multiple var's. When one of my var's changes (formation), I want to run an updateOrCreateContent(). I had thought I could just do this with a bit of combine, but I'm struggling to get it working... The code below has a compile error at $formation When I mark formation @Published, it generates a different compile error: "Invalid redeclaration of synthesized property '_formation'" any help appreciated thanks class LayoutModel { var players: [Player] = [] var formation: Formation = .f433 var cancellables = Set<AnyCancellable>() init(players: [Player], formation: Formation) { self.players = players self.formation = formation updateOrCreateContent() $formation.sink(receiveValue: { _ in self.updateOrCreateContent() }) .store(in: &cancellables) }

My app has a collection of Cell Views. some of the views' model objects include a Player, and others do not. I want to use drag and drop to move a player from one cell to another. I only want cells that contain a player to be valid drag sources. All cells will be valid drop destinations. When I uncomment the .disabled line both drag and drop become disabled. Is it possible to keep a view enabled as a dropDestination but disabled as a draggable source? VStack { Image("playerJersey_red") if let player = content.player { Text(player.name) } } .draggable(content) // .disabled(content.player == nil) .dropDestination(for: CellContent.self) { items, location in One thing I tried was to wrap everything in a ZStack and put a rectangle with .opacity(0.02) above the Image/Text VStack. I then left draggable modifying my VStack and moved dropDestination to the clear rectangle. This didn't work as I wasn't able to initiate a drag when tapping on the rectangle. Any other ideas or suggestions? thanks

I want to use AppStorage for a custom struct I am using struct Activities { var name: String var age: Int } struct ContentView: View { @AppStorage("key") private var activities: Activities = .init(name: "Albert", age: 42) var body: some View { VStack { TextField("Activity Name", text: $activities.name) } } } The above code generates a compiler warning, recommending I add RawRepresentable conformance. So I've added it like this: extension Activities: RawRepresentable { public init?(rawValue: String) { guard let data = rawValue.data(using: .utf8) else { return nil } do { let result = try JSONDecoder().decode(Activities.self, from: data) self = result } catch { print(error) return nil } } var rawValue: String { guard let data = try? JSONEncoder().encode(self), let result = String(data: data, encoding: .utf8) else { return "{}" } return result } } This leads to a stack overflow because calling encode from rawValue calls rawValue. :-( I overcame this by declaring Codable conformance and overriding the default Encodable implementation: extension Activities: Codable { enum CodingKeys: String, CodingKey { case name case age } func encode(to encoder: any Encoder) throws { var container = encoder.container(keyedBy: CodingKeys.self) try container.encode(name, forKey: .name) try container.encode(age, forKey: .age) } } This solves the stack overflow, but now init?(rawValue: String) is failing and I'm not sure why. When I set a breakpoint in my catch block I see the following: (lldb) po error ▿ DecodingError ▿ typeMismatch : 2 elements - .0 : Swift.String ▿ .1 : Context - codingPath : 0 elements - debugDescription : "Expected to decode String but found a dictionary instead." - underlyingError : nil (lldb) po rawValue {"name":"Albert2","age":42} (lldb) po data ▿ 27 bytes - count : 27 ▿ bytes : 27 elements - 0 : 123 - 1 : 34 - 2 : 110 - 3 : 97 - 4 : 109 - 5 : 101 - 6 : 34 - 7 : 58 - 8 : 34 (truncated to save space for posting :-)
