import SwiftUI struct ProviderCalendarView: View { @StateObject var viewModel = YearViewModel() @State private var selectedYear = 3 var body: some View { VStack { HStack { Picker(selection: $selectedYear) { ForEach(viewModel.years, id: \.self) { year in Text("\(year)") } } label: { } } } } } class YearViewModel: ObservableObject { @Published var years: [Int] = [] init() { createYears() } func createYears() { let now = Date() for i in 0..<4 { years.append(2023 + i) } } } I don't use Range to create an array in this case. Yet, I still get the same compiler guy.

Silly me... func fileWrapper(configuration: WriteConfiguration) throws -> FileWrapper { let fileContent = try JSONEncoder().encode(self.document) return FileWrapper(regularFileWithContents: fileContent) }

Hmm... Maybe let fileWrapper = FileWrapper(directoryWithFileWrappers: [filename: jsonFileWrapper]) is wrong?

I think I've fixed it. import SwiftUI struct ContentView: View { @State var selectedTab = 0 @State var addTapped = false @State var refresh = false @State var people = [ Person(name: "Alice", systemImage: "person.circle.fill"), Person(name: "Jane", systemImage: "person.circle.fill"), Person(name: "Dave", systemImage: "person.circle.fill"), Person(name: "Susan", systemImage: "person.circle.fill"), Person(name: "Robert", systemImage: "person.circle.fill"), Person(name: "Daniel", systemImage: "person.circle.fill") ] var body: some View { VStack(alignment: .leading, spacing: 0) { ScrollView(.horizontal) { HStack(spacing: 20) { ForEach(0..<people.count, id: \.self) { num in VStack { ... } .foregroundColor(selectedTab == num ? Color.blue : Color.gray) .onTapGesture { self.selectedTab = num } } } }.padding(.horizontal, 10) Spacer() .frame(height: 2) Rectangle().fill(.gray) .frame(height: 1) TabView(selection: $selectedTab) { ForEach(0..<people.count, id: \.self) { num in let person = people[num] Text(person.name) .tag(person.id) } } } .tabViewStyle(.page(indexDisplayMode: .never)) // <<<<<<<<<<<<<<<<<<<<< .onAppear { UITabBar.appearance().isHidden = true } } }

I think my topic is related to https://developer.apple.com/forums/thread/697197 .

Thank you for your reply. Yes and no. I've figured out that I can do it by having an additional Date attribute. So I've started with a new Xcode project by having a new Date attribute named createdAt. And code goes as follows. import SwiftUI struct ContentView: View { @Environment(\.managedObjectContext) var managedObject @FetchRequest(sortDescriptors: [NSSortDescriptor(keyPath: \Student.createdAt, ascending: true)]) var students: FetchedResults<Student> var body: some View { VStack { List(students) { student in Text(student.name ?? "") } Button { let firstNames = ... let lastNames = ... if let selectedFirstName = firstNames.randomElement(), let selectedLastName = lastNames.randomElement() { let newStudent = Student(context: managedObject) newStudent.id = UUID() newStudent.name = "\(selectedFirstName) \(selectedLastName)" newStudent.createdAt = Date() // <<<<<<<<<<<<<<<<<<<<<< try? managedObject.save() } } label: { Text("Add") } } } } , which takes care of the sort issue. As for the older project shown above, I wonder if Core Data has a simple mechanism in reordering the records when the entity does not include an additional Date attribute? That was my initial question.

No, I haven't. I don't even remember having posted this question although I know what this case is about.

Thanks. I'm not sure how that helps, though. In the meantime, Paul from Hacking with Swift shows how the List guy works. I've tested the exact lines of code he has, and the selection symbol doesn't appear, either. That's odd. The article is not even one year old. By the way, I'm using Xcode 14.3. https://www.hackingwithswift.com/quick-start/swiftui/how-to-allow-row-selection-in-a-list

Hmm... I'm sorry. I realize that I should have done that. I cannot edit the topic any more.

It's cheesy, but I guess one way of doing it is to use Circle().stroke.

I got it.

I guess it's the matter of setting a preset to AVCaptureSession.

If I set the preset to captureSession.sessionPreset = .hd1280x720 , I get a different image.

I've ended up with the following lines of code. func prepareCamera(cameraCase: CameraCase) { /* removing existing layers */ if let sublayers = self.view.layer.sublayers { for sublayer in sublayers { if sublayer.isKind(of: AVCaptureVideoPreviewLayer.self) { sublayer.removeFromSuperlayer() } } } /* creating a capture session */ captureSession = AVCaptureSession() guard let device = AVCaptureDevice.DiscoverySession(deviceTypes: [.builtInWideAngleCamera], mediaType: AVMediaType.video, position: cameraCase == .front ? .front : .back).devices.first else { return } let videoInput = try? AVCaptureDeviceInput(device: device) if captureSession.canAddInput(videoInput!) { captureSession.addInput(videoInput!) imagePhotoOutput = AVCapturePhotoOutput() // setting output destination captureSession.addOutput(imagePhotoOutput) // adding photo output to session } /* creating a capture layer */ let previewLayer: AVCaptureVideoPreviewLayer = AVCaptureVideoPreviewLayer.init(session: captureSession) previewLayer.videoGravity = AVLayerVideoGravity.resizeAspect /* adding video capture layer to the view layer */ self.view.layer.addSublayer(previewLayer) /* starting capture session */ DispatchQueue.global(qos: .background).async { self.captureSession.startRunning() } }

Oops... The position argument is the other way around.
