Any idea how I can solve it? My goal is to add a snapshot l

I'm working on a calculator app but I'm having trouble displaying the results of a function. When I press a button in ButtonView, a function runs to calculate the result but that result does not display in CalculationCircleView. Main View: struct ScoreCalculatorView: View { @StateObject private var viewModel = ViewModel() var body: some View { VStack { Spacer() HStack { CalculationCircleView(calculation: viewModel.grossScore, label: Score) Spacer() CalculationCircleView(calculation: viewModel.plusMinus, label: +/-) } .padding(.horizontal, 30) Spacer() LazyVGrid(columns: viewModel.columns, spacing: 20) { ForEach(0..<4, id: .self) { index in ZStack { DataCellsView(labels: viewModel.scoreLabels[index]) TextField((viewModel.scoreLabels[index]), text: $viewModel.scoreData[index]) .font(.largeTitle) .fontWeight(.light) .frame(maxWidth: 80) .multilineTextAlignment(.center) .keyboardType(.numberPad) } } } .frame(width: 250) Spacer() ButtonView(data: viewModel.scoreData) .padding(.bottom, 20) } } } Calcula

since 14.3 update I'm missing the type and value column in the Project->Target->%target%->Info view. I only can see the key column. I've already reinstalled Xcode multiple times and restarted my MacBook Pro. Here the screenshot from the new created project: I can add new properties, but I can't change the value. Has anyone some idea, what I can do to fix this problem? Btw: my workmate with similar MacBook Pro setup can change all the values.

I have a csv file with values ranges between 0-1. When converted this csv values to MLMultiArray and then to UIImage it shows grey image. But the image is actually coloured. So is there any step missing or do I have to perform any more action to get this image to be coloured. Sample csv values - [0.556862745 0.62745098 0.811764706] Code func parseCSV(data: String) -> [Float] { var finalArray = [Float]() var rows = data.components(separatedBy: n) for row in rows { let columns = row.components(separatedBy: ,) if columns.count == 3 { let r = columns[0] let g = columns[1] var b = columns[2] if b.contains(r){ b = b.replacingOccurrences(of: r, with: ) } finalArray.append(Float(r)!) finalArray.append(Float(g)!) finalArray.append(Float(b)!) } } return finalArray } let m = try MLMultiArray(shape: [1, 768, 512, 3], dataType: .double) for (index, element) in data.enumerated() { m[index] = NSNumber(value: element) } let model: ModelInput = { do { let config = MLModelConfiguration()

Hi everyone, I'm having a hard time figuring out why the code below results in weird behaviour with the ScrollView. Code : struct MainView: View { @State var strings: [String] = [A, B, C, D, E] @State var ints: [Int] = Array(1...300) @State var selectedInt: Int? var body: some View { ZStack { ScrollView { VStack { ForEach(strings, id: .self) { string in VStack { HStack { Text(string) Spacer() } LazyVGrid(columns: [GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible())]) { ForEach(ints, id: .self) { int in VStack { Text(String(int)) Spacer() } .frame(minWidth: 0, maxWidth: .infinity) .frame(height: 200) .background( RoundedRectangle(cornerRadius: 5) .fill(int % 2 == 0 ? .orange : .green) ) .onTapGesture { self.selectedInt = int } } } } } } .padding() } if let selectedInt { VStack { Spacer() Text(String(selectedInt)) Spacer() Button { self.selectedInt = nil } label: { Image(systemName: x.circle) .resizable() .scaledToFit() .frame(width: 30) } } .frame(minWidth: 0, maxWidth: .infinity, minH

I'm using a two column NavigationSplitView, where the view passed for the detail column is the root of a NavigationStack. The navigation works as expected, but the navigationTitle and toolbar elements of the detail view are very slightly delayed when the view appears on iOS, such that they 'pop' in rather than smoothly animating like normal. Returning to the root of the view from views higher in this stack animates as expected. Has anyone seen anything like this before? Thanks!

Hi :-) I´m looking for some help and advice for my little project. Basically I have a Tabview with 3 Tabs. One of them is a View for Favorites. I managed the selection and the saving of the favorites. However, the View for the Favorites is not updating while the app is running. Just when the app is closed and restarted the View of Favorites gets updated. The Array of Favorites is marked with @Published, the variable in the Favorites-View is marked as @ObservedObject. I searched a lot and can't find my mistake. „Expression“ is a Struct with about 10 properties. Class for the Favorites: class Favorites: ObservableObject { @Published var favoriteExpressions: [Expression] = [] { didSet { print(Favorites changed) } } private let saveKey = FavoriteExpressions let defaults = UserDefaults.standard init() { if let data = defaults.data(forKey: saveKey) { let decoder = JSONDecoder() if let decoderSet = try? decoder.decode([Expression].self, from: data) { favoriteExpressions = decoderSet } } } func contains() -> Bool

Hi, the problem is not dangerous to life, I don't want see the yellow button on top of the editor. 'Autoresizing Mask' is set to about 50 items, that works, except tableView, 10 warnings. The tableView has 10 columns of 20 pixels width, min 10 and max 100000. The ' Add new constraints' options are all grayed, so what ? In an other project a warning was set for arrayController, I don't like Auto Layout, the blue help lines are enough. My question is : How do i can suppress this warnings ? Kindly, Uwe

The below code works. I pass in an array of core data entities and display attributes in a table. In the second table column I use a switch case statement to handle the 3 possible attributes I want to display. I could eliminate the switch case if I could figure out how to access a given core data attribute via a variable that contains the specific attribute name but have been unable to determine how to do so. Two attempts are commented out in the code. struct DataTable: View { private var closingValues: Array var heading: String var attribute: String init(closingValues: [TradingDayPrices], heading: String, attribute: String) { self.closingValues = closingValues self.heading = heading self.attribute = attribute } var body: some View { Text(heading) .foregroundColor(.black) .font(Font.custom(Arial, size: 18)) .bold() .padding(.top, 10) Table(self.closingValues) { TableColumn(Date) { value in HStack { Spacer() Text(dateToStringFormatter.string(from: value.timeStamp!)) Spacer() } } .width(100) TableColum

I'm trying to find the reason for multiple app crashes. App Store Connect shows multiple crashes but the Organizer in Xcode lists a lot of crashes but very few entries have any data. Image is only one of many cases in the organizer. 2nd column from left shows 3 devices but right column shows 0 devices.
