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.

Hi! When using the Sample NavigationCookbook in the two column layout, the selection in the first column is not remembered, when navigating to the Home Screen and back. This behaviour can be reproduced by starting the app on the iPad or simulator, selecting for example Pancake and then navigating to the home screen and back into the navigation. Sometimes this (the navigation to/back from the home screen) has to be done twice, to lose the selection. In the console log you can see the message Update NavigationAuthority bound path tried to update multiple times per frame. appearing. Not sure if this has something todo with the selection being lost. This is on iOS 16.4.1 not sure if the behaviour before was different. Anybody experiences the same behaviour? Bug in SwiftUI or in the sample app? Cheers, Michael

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 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 change my /private/etc permissions to eveybody can read and write, and applied this permission to all sub-folders and files. (something ****** to do)After that, when I use sudo command something went wrong:sudo: unable to stat /etc/sudoers: Permission deniedsudo: no valid sudoers sources found, quittingsudo: unable to initialize policy pluginAlso, I make a change to my sudoer file when trying to solve the problem.Here is its content:----------------------------------------------------------------------------------------------------------------------------------------# # Sample /etc/sudoers file. # # This file MUST be edited with the 'visudo' command as root. # # See the sudoers man page for the details on how to write a sudoers file. ## # Override built-in defaults ## Defaults env_reset Defaults env_keep += BLOCKSIZE Defaults env_keep += COLORFGBG COLORTERM Defaults env_keep += __CF_USER_TEXT_ENCODING Defaults env_keep += CHARSET LANG LANGUAGE LC_ALL LC_COLLATE LC_CTYPE Defaults env_keep += LC_MESSAGES LC_M

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

Hello! I've noticed that when I am using NavigationSplitView and I minimize the app on iPadOS and then resume, if I am using a 2 column setup it loses state upon resume. This does not appear to happen on with a 3 column setup though. I'm wondering if others have run into this and if anyone has figured out a way around it. It seems like it's a bug and I should file a bug for it, but wanted to check with more people first. Here's some example code, run it, select your number of columns, then minimize the app, count to 3 (because why not!) and open the app and you'll notice that $selection is now nil. import SwiftUI struct Item: Identifiable, Hashable { var id: Int var name: String var description: String } struct ContentView: View { @State var selection: Item? var items: [Item] = [ .init(id: 1, name: One, description: Is the loneliest number), .init(id: 2, name: Two, description: Two can be as bad as one), .init(id: 3, name: Three, description: Three Dog Night) ] var body: some View {

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.
