I'm getting this error when attempting to upload an iOS app to iTunes Connect. I've tried using Transporter, and get the same result.I've also tried uploading a new version of an app that uploaded correctly in November and got the same result.Does anyone have any suggestions for possible causes for this error?thanks,

When I: open a simulator (eg iPhone 15, iOS 17.0) open the Photos app tap on an image (either one that comes included, or something I've saved to PhotoRoll) tap Edit I see the typical Photos Edit view with two key differences. the image is not visible, the middle of the view is all black there are now Cancel/Done/Dismiss buttons. I need to force quit to get back to the Springboard (Is that still the correct term?) Am I doing something wrong, or should the simulator's Photo's app be providing a better edit experience?

Pretty sure this is a no-no, but asking just in case there's an easy way to make this work struct DocumentContentView: View { private static let logger = Logger( subsystem: "mySubsystem", category: String(describing: Self.self) ) var body: some View { VStack { Text("Hello") logger.trace("hello") } } } This code generates the following compile error at the logger.trace line buildExpression is unavailable: this expression does not conform to View I suspect every line of the body var (or any @ViewBuilder - designated code?) needs to 'return' a View. Is this correct? or more importantly any work arounds other than putting some/all of the view contents in a. func()?

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.

See sample code below... Basically it's a galleryView with a dataSource that can add/remove items dynamically. It works as expected when GalleryView's dataSource variable has a type (that conforms to ObservableObject) However when I change dataSource's type to be a protocol, I can't seem to get my code to compile. Any guidance on how to use a protocol in GalleryView, and continue to keep the UI updating when the model object's item list changes? thanks! Mike protocol GalleryDataSource: ObservableObject {     var itemCount: Int { get }     func item(for index: Int) - String } class GalleryModel: ObservableObject {     static let test1: GalleryModel = GalleryModel(items: ["A","B","C"])     @Published var items: [String]     init(items: [String]) {         self.items = items     } } extension GalleryModel: GalleryDataSource {     var itemCount: Int {         return items.count     }     func item(for index: Int) - String {         return items[index]     } } struct ContentView: View {     var model: GalleryModel = GalleryModel.test1     var body: some View {         VStack {             GalleryView(dataSource: model)             Button("Add Item") {                 model.items.append("\(model.items.count)")             }         }     } } struct GalleryView: View {     @ObservedObject var dataSource: GalleryModel //GalleryDataSource     var body: some View {         ScrollView(.horizontal, content: {             HStack {                 ForEach(0..self.dataSource.itemCount, id:\.self) { index in                     Text(dataSource.item(for: index))                         .padding()                 }             }         })     } }

I'm trying to find a syntactically correct way to put the contents of a Container in a separate variable (or function). Can anyone steer me in the right direction? thanks, in advance, mike struct ContentView: View { var body: some View { VStack(content: containerContent) .padding() } var containerContent: () -> Content { return { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") } } }

I have a SwiftUI view that works as expected in a full SwiftUI context. But I now need to use it in a UIViewController. It mostly works, but I'm trying to expose an @State var out to the viewController, and it only ever returns the initial value. Any guidance for how best to pass out this @State var? I could make it be a binding, but in my pure SwiftUI code, it works fine as @State (ie EditorView's container view does not need to know about sliderVal) thanks, in advance, for any suggestions import SwiftUI import UIKit class ViewController: UIViewController { var host: UIHostingController<EditorView>? override func viewDidLoad() { super.viewDidLoad() host = .init(rootView: EditorView()) guard let host = host else { return } addChild(host) host.view.translatesAutoresizingMaskIntoConstraints = false view.addSubview(host.view) host.didMove(toParent: self) } @IBAction func helloTapped(sender: UIButton) { guard let sliderValue = host?.rootView.sliderVal else { return } print("UIKit sliderValue: \(sliderValue)") } } struct EditorView: View { @State var sliderVal: Double init(sliderVal: Double? = nil) { _sliderVal = State(initialValue: sliderVal ?? 7) } var body: some View { VStack { Slider(value: $sliderVal, in: 1...10) Text("sliderVal: \(sliderVal)") } } } (NOTE: in order to see this code snippet in action you will need to create a button in the storyboard and link it to helloTapped)

This first code works fine decoding json. static let localizationsDictText = """ { "en" : { "string" : "Cat" }, "fr" : { "string" : "Chat"} } """ struct Localization: Codable, Equatable { let string: String } typealias LocalizationsDict = [String: Localization] func testExample() throws { let text = Self.localizationsDictText let data = text.data(using: .utf8, allowLossyConversion: false) let localizationsDict = try JSONDecoder().decode(LocalizationsDict.self, from: data!) XCTAssertEqual(localizationsDict.keys.count, 2) } But then I try to create a modified version of the above, only changing the type of the LocalizationsDict key from String to an enum: enum Language: String, CaseIterable, Codable { case en = "en" case fr = "fr" } typealias LocalizationsDict2 = [Language: Localization] func testExample2() throws { let text = Self.localizationsDictText let data = text.data(using: .utf8, allowLossyConversion: false) let localizationsDict = try JSONDecoder().decode(LocalizationsDict2.self, from: data!) XCTAssertEqual(localizationsDict.keys.count, 2) } and the JSONDecoder line throws an exception: testExample2(): failed: caught error: "typeMismatch(Swift.Array<Any>, Swift.DecodingError.Context(codingPath: [], debugDescription: "Expected to decode Array<Any> but found a dictionary instead.", underlyingError: nil))" Any suggestions as to why switching from [String: Localization] to [Language: Localization] might cause JSONDecode() to treat it like an array? Thanks in advance for any guidance.

I am using @AppStorage in a model object (see code below that works as expected). class ModelObject { static let shared = ModelObject() @AppStorage("enhanced") var scriptPickers: Bool = true var defaultDependentValue: String { scriptPickers ? "Enhanced" : "NOT enhanced" } } struct ContentView: View { @AppStorage("enhanced") var scriptPickers: Bool = true var body: some View { VStack { Toggle(isOn: $scriptPickers, label: { Text("userDefault val") }) Text("value: \(ModelObject.shared.defaultDependentValue)") } } } Now I want to test my model object in a way that will allow me to use a mock instance of UserDefaults, but am having trouble with the syntax. I tried adding a userDefaults var, and referring to the var in the @AppStorage class ModelObject { static let shared = ModelObject() let userDefaults: UserDefaults init(userDefaults: UserDefaults = .standard) { self.userDefaults = userDefaults } @AppStorage("enhanced", store: userDefaults) var scriptPickers: Bool = true var defaultDependentValue: String { scriptPickers ? "Enhanced" : "NOT enhanced" } } However I can't find a way to avoid the syntax error this generates: Cannot use instance member 'userDefaults' within property initializer; property initializers run before 'self' is available Any guidance on how I might be able to: continue using @AppStorage be able to test my class in a way that doesn't force me to use UserDefaults.standard thanks, in advance, Mike

In V 0.1 of my app, I went with a simple option for a piece of business logic in my app. I then changed something else that caused my simplified business logic to now crash the app at startup. Excellent, a chance to use Test. Driven Design to replace my flawed business logic. So I wrote my first test TDD test, but when I tried to run the test... It doesn't run because running the test target seems to start by actually running my full app (which as I described in chapter 1 is currently crashing) Have I configured something incorrectly? or is it normal that when I attempt to run a single test, step 1 is running the full app? (note: it is very easy for me to disable/avoid the business logic causing my crash. This question is more about my lack of understanding of what it means to run a test target.) thanks in advance for any and all responses. Mike

I've defined a value stored in UserDefaults. In a view struct I have code that can successfully update the stored value. I've also added an @AppStorage var in an instance of a class, that can read this value and run business logic that depends on the current stored value. But what I really want to do, is have code in my class that gets automatically called when the value stored in UserDefaults gets updated. Basically I want to do this: @AppStorage("languageChoice") var languageChoice: LanguageChoice = .all { didSet { print("hello") } } Unfortunately didSet closures in @AppStorage vars do not appear to get called :-( My clumsy attempts to use combine have all ended in tears from the compiler. Any/all suggestions are greatly appreciated. thanks, Mike

From what I've read, @AppStorage vars should be @Published, however the following code generates a syntax error at extended's .sink modifier: Cannot call value of non-function type 'Binding<Subject>' class LanguageManager: ObservableObject { @Published var fred = "Fred" @AppStorage("extended") var extended: Bool = true private var subscriptions = Set<AnyCancellable>() init() { $fred .sink(receiveValue: {value in print("value: \(value)") }) .store(in: &subscriptions) $extended .sink(receiveValue: {value in print("value: \(value)") }) .store(in: &subscriptions) } Does anyone know of a way to listen for (subscribe to) changes in @AppStorage values? didSet works in for a specific subset of value changes, but this is not sufficient for my intended use.

I thought the following code would allow me to have focus in the TextField when the app loads. Is there something else/different that I need to do? struct ContentView: View { enum FocusField { case password } @State var fieldContent: String = "" @FocusState var focus: FocusField? var body: some View { VStack { TextField("Enter text here", text: $fieldContent) .focused($focus, equals: .password) Text("Hello, world!") } .padding() .defaultFocus($focus, .password) } }

I have a CoreImage pipeline and one of my steps is to rotate my image about the origin (bottom left corner) and then translate it. I'm not seeing the behaviour I'm expecting, and I think my problem is in how I'm combining these two steps. As an example, I start with an identity transform (lldb) po transform333 ▿ CGAffineTransform - a : 1.0 - b : 0.0 - c : 0.0 - d : 1.0 - tx : 0.0 - ty : 0.0 I then rotate 1.57 radians (approx. 90 degrees, CCW) transform333 = transform333.rotated(by: 1.57) - a : 0.0007963267107332633 - b : 0.9999996829318346 - c : -0.9999996829318346 - d : 0.0007963267107332633 - tx : 0.0 - ty : 0.0 I understand the current contents of the transform. But then I translate by 10, 10: (lldb) po transform333.translatedBy(x: 10, y: 10) - a : 0.0007963267107332633 - b : 0.9999996829318346 - c : -0.9999996829318346 - d : 0.0007963267107332633 - tx : -9.992033562211013 - ty : 10.007960096425679 I was expecting tx and ty to be 10 and 10. I have noticed that when I reverse the order of these operations, the transform contents look correct. So I'll most likely just perform the steps in what feels to me like the incorrect order. Is anyone willing/able to point me to an explanation of why the steps I'm performing are giving me these results? thanks, mike

For my app I've created a Dictionary that I want to persist using AppStorage In order to be able to do this, I added RawRepresentable conformance for my specific type of Dictionary. (see code below) typealias ScriptPickers = [Language: Bool] extension ScriptPickers: @retroactive RawRepresentable where Key == Language, Value == Bool { public init?(rawValue: String) { guard let data = rawValue.data(using: .utf8), let result = try? JSONDecoder().decode(ScriptPickers.self, from: data) else { return nil } self = result } public var rawValue: String { guard let data = try? JSONEncoder().encode(self), // data is Data type let result = String(data: data, encoding: .utf8) // coerce NSData to String else { return "{}" // empty Dictionary represented as String } return result } } public enum Language: String, Codable, { case en = "en" case fr = "fr" case ja = "ja" case ko = "ko" case hr = "hr" case de = "de" } This all works fine in my app, however trying to run any tests, the build fails with the following: Conflicting conformance of 'Dictionary<Key, Value>' to protocol 'RawRepresentable'; there cannot be more than one conformance, even with different conditional bounds But then when I comment out my RawRepresentable implementation, I get the following error when attempting to run tests: Value of type 'ScriptPickers' (aka 'Dictionary<Language, Bool>') has no member 'rawValue' I hope Joseph Heller is out there somewhere chuckling at my predicament any/all ideas greatly appreciated
