column

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.

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

Hey guys, I'm having a huge problem and can't understand how to fix it. I was trying to recreate an Xcode app project with a Xcode Playground, now the point is that in Xcode Project on the side of the screen there are the options to add files. Like this: And in the Playground it is like this: But here, when I add the Swift Files under Shared Sources, and create the ContentView() in Main - Xcode Playground, it says me that it can't find the Helicopter, Pixel, Obstacle, so it can't find the Shared Recourses' files. Here's all the code. ContentView(Main): import SwiftUI import PlaygroundSupport struct ContentView: View { @State private var heliPosition = CGPoint(x:100, y: 100) @State private var obstPosition = CGPoint(x:1000, y: 300) @State private var isPaused = false @State private var score = 0 @State var timer = Timer.publish(every: 0.1, on: .main, in: .common).autoconnect() var body: some View { GeometryReader { geo in ZStack{ Helicopter() .position(self.heliPosition) .onReceive(self.timer) {_ in self.gravi

Hi ! I am having a very strange problem. I display a list of elements, and I created a view that takes this element as a parameter in order to allow the user to modify it in another view. my var with a forEach : @Binding var liste : Liste my code : ScrollView { LazyVGrid(columns: [GridItem(.adaptive(minimum: 100))], spacing: 5) { ForEach(liste.cartes) { c in NavigationLink(destination: ModifierUneCarte(carte: c)) { VStack { Text(c.devant) .font(.system(size: 14)) Divider() Text(c.derriere) .font(.system(size: 14)) } } } } } and my ModifierUneCarte : struct ModifierUneCarte: View { [...] @Binding var carte: Carte [...] And I have this error on a lot of lines : Conflicting arguments to generic parameter 'Content' ('<>' vs. '<>' vs. '<>' vs. '<>') but it's because of : NavigationLink(destination: EditMap(map: c)) { because when I remove it everything works...
