I'm trying to create a List that allows multiple selection. Each row can be edited but the issue is that since there's a tap gesture on the Text element, the list is unable to select the item. Here's some code: import SwiftUI struct Person: Identifiable { let id: UUID let name: String init(_ name: String) { self.id = UUID() self.name = name } } struct ContentView: View { @State private var persons = [Person("Peter"), Person("Jack"), Person("Sophia"), Person("Helen")] @State private var selectedPersons = Set<Person.ID>() var body: some View { VStack { List(selection: $selectedPersons) { ForEach(persons) { person in PersonView(person: person, selection: $selectedPersons) { newValue in // ... } } } } .padding() } } struct PersonView: View { var person: Person @Binding var selection: Set<Person.ID> var onCommit: (String) -> Void = { newValue in } @State private var isEditing = false @State private var newValue = "" @FocusState private var isInputActive: Bool var body: some View { if isEditing { TextField("", text: $newValue, onCommit: { onCommit(newValue) isEditing = false }) .focused($isInputActive) .labelsHidden() } else { Text(person.name) .onTapGesture { if selection.contains(person.id), selection.count == 1 { newValue = person.name isEditing = true isInputActive = true } } } } } Right now, you need to tap on the row anywhere but on the text to select it. Then, if you tap on the text it'll go in edit mode. Is there a way to let the list do its selection? I tried wrapping the tap gesture in simultaneousGesture but that didn't work. Thanks!

I tried to create a Text View using attributedString. I want to set the line height using paragraphStyle and return the Text, but paragraphStyle is not being applied. Why is that? extension Text { init?(_ content: String, font: StyleType, color: Color = .ppBlack) { var attributedString = AttributedString(content) attributedString.font = Font.custom(font.fontWeight, fixedSize: font.fontSize) attributedString.foregroundColor = color let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.minimumLineHeight = 16 paragraphStyle.maximumLineHeight = 16 paragraphStyle.lineSpacing = 0 attributedString.mergeAttributes(.init([.paragraphStyle: paragraphStyle])) self = Text(attributedString) } }

I have a use case in which there is a zoomable and pannable parent view, and a child view that needs to display a custom context menu on long press. (The reason why I need to implement a custom context menu is this: https://developer.apple.com/forums/thread/773810) It seems, however, that this setup produces a bug in SwiftUI. The problem is that the onChanged of the drag gesture is only invoked right before its onEnded, hence you cannot smoothly animate the drag: struct ContentView: View { var body: some View { ZStack { Rectangle() .foregroundStyle(.green) .frame(width: 200, height: 200) .onLongPressGesture { print("long press") } } .gesture(MagnifyGesture().onEnded { value in print("magnify end") }) .gesture(DragGesture() .onChanged { value in print("drag change") } .onEnded { value in print("drag end") }) } } Changing the DragGesture to a .highPriorityGesture() makes the drag's onChange execute at the correct time but results in the LongPressGesture only triggering when the user lifts up his/her finger (which was originally not the case). So it seems that the two gestures are in a sort of conflict with each other. Is there a workaround?

In UIKit, it's quite common for table views to have one (or sometimes more) rows whose editing style is "insert", which show up a button with a plus symbol on a green background to the left of the cell content, and tapping this button adds whatever is in the cell content (usually a text field) to the list. What's the procedure for creating a list row like this in Swift UI when in edit mode?

When I created a search box on the homepage, I was able to enter text in the input field while previewing in Xcode. However, after clicking "Build" and running the app, I couldn't type anything into the input field in the demo interface. Additionally, I received the following error message: If you want to see the backtrace, please set CG_NUMERICS_SHOW_BACKTRACE environmental variable. Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem. How can I fix this issue? Here is my ContentView.swift code: import SwiftUI struct ContentView: View { @State private var searchText: String = "" @State private var isSearching: Bool = false var body: some View { NavigationStack { GeometryReader { geometry in VStack { Spacer() .frame(height: geometry.size.height.isNaN ? 0 : geometry.size.height * 0.3) VStack(spacing: 20) { Text("NMFC CODES LOOKUP") .font(.title2) .bold() TextField("Search...", text: $searchText) .textFieldStyle(PlainTextFieldStyle()) .padding(10) .frame(height: 40) .frame(width: geometry.size.width.isNaN ? 0 : geometry.size.width * 0.9) .background(Color.white) .cornerRadius(8) .overlay( HStack { Spacer() if !searchText.isEmpty { Button(action: { searchText = "" }) { Image(systemName: "xmark.circle.fill") .foregroundColor(.gray) .padding(.trailing, 8) } } } ) .overlay( RoundedRectangle(cornerRadius: 8) .stroke(Color.gray.opacity(0.5), lineWidth: 1) ) Button(action: { isSearching = true }) { Text("Search") .foregroundColor(.white) .frame(width: geometry.size.width * 0.9, height: 40) .background(Color.blue) .cornerRadius(8) } .disabled(searchText.isEmpty) Text("Created & Designed & Developed By Matt") .font(.caption) .foregroundColor(.gray) .padding(.top, 10) } Spacer() .frame(height: geometry.size.height * 0.7) } .frame(width: geometry.size.width) } .background(Color(red: 250/255, green: 245/255, blue: 240/255)) .navigationDestination(isPresented: $isSearching) { SearchResultsView(searchQuery: searchText) } } .background(Color(red: 250/255, green: 245/255, blue: 240/255)) .ignoresSafeArea() } } #Preview { ContentView() }

Hi I am developing an app for counting money. One view is for entering the intended destinations specified by a donor. Each destination has a row with a TextField that has an OnChange to keep it all numeric. The model that holds the data is a class called AllocationItems, which I recently changed from having the protocol ObservableObject to having the macro @Observable. It mostly works the same, except that before with each key stroke the total would be updated, but now with the macro it only gets updated when I exit the current TextField by clicking on another TextField How do I get it to update the total with each keystroke? The code that shows the total is this: Text(allocations.totalAllocated.fmtCurrency) where allocations is an instance of AllocationItems with this definition: var totalAllocated: NSDecimalNumber { items.reduce(.zero) { $0 + $1.amountValue } } I hope someone knows why this has changed and can suggest a simple fix.

When picking a photo in the gallery, whatever the orientation of the original image, size is always as landscape if let image = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.editedImage)] as? UIImage { print("picked original", image.size) For a portrait photo: picked original (1122.0, 932.0) For a landscape: picked original (1124.0, 844.0) What am I missing ?

Currently I came across an issue in mac catalyst project. All the buttons in my project are not visible, they are in their actual positions and also clickable and performing their tasks as assigned but they are not visible. When Iam doing: crossButton.setImage(UIImage(named: "CrossComMac"), for: .normal) Button does not contain image While in the below code, image is visible but Iam not able to resize it. crossButton.imageView?.image = UIImage(named: "CrossComMac") Also title of the button is not visible too. Anything related to button in my mac catalyst project is not visible. Main issue: Button's image is visible in Xcode running project Button's image is not visible in build project...(funny thing right)

When pushing a page in the navigation， changing the state of interactivePopGestureRecognizer causes the page to freeze. Just like this: #import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. CGFloat red = (arc4random_uniform(256) / 255.0); CGFloat green = (arc4random_uniform(256) / 255.0); CGFloat blue = (arc4random_uniform(256) / 255.0); CGFloat alpha = 1.0; // self.view.backgroundColor = [UIColor colorWithRed:red green:green blue:blue alpha:alpha]; UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; btn.frame = CGRectMake(0, 0, 100, 44); btn.backgroundColor = [UIColor redColor]; btn.center = self.view.center; [btn setTitle:@"push click" forState:UIControlStateNormal]; [btn addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:btn]; } - (void)click:(id)sender { [self.navigationController pushViewController:[ViewController new] animated:YES]; } - (void)viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; self.navigationController.interactivePopGestureRecognizer.enabled = NO; } - (void)viewDidAppear:(BOOL)animated{ [super viewDidAppear:animated]; self.navigationController.interactivePopGestureRecognizer.enabled = YES; } @end

I must admit my knowledge of swift is limited, and I cannot wrap my head around this problem. I've defined this protocol, so I can use different auth providers in my app. protocol AuthRepository { associatedtype AuthData associatedtype AuthResponseData associatedtype RegistrationData associatedtype RegistrationResponseData func login(with data: AuthData) async throws -&gt; AuthResponseData? func register(with data: RegistrationData) async throws -&gt; RegistrationResponseData? } and an implementation for my server struct MyServerAuthData { let email: String let password: String } struct MyServerAuthResponseData { let token: String } struct MyServerRegistrationData { let email: String let password: String let name: String } actor AuthRepositoryImpl: AuthRepository { func login(with data: MyServerAuthData) async throws -&gt; MyServerAuthResponseData? { ... } func register(with data: MyServerRegistrationData) async throws -&gt; Void? { ... } } To use across the app, I've created this ViewModel @MainActor final class AuthViewModel&lt;T: AuthRepository&gt;: ObservableObject { private let repository: T init(repository: T) { self.repository = repository } func login(data: T.AuthData) async throws -&gt; T.AuthResponseData? { try await repository.login(with: data) } func register(with data: T.RegistrationData) async throws { try await repository.register(with: data) } } defined in the app as @main struct MyApp: App { @StateObject var authViewModel = AuthViewModel(repository: AuthRepositoryImpl()) var body: some Scene { WindowGroup { ContentView() .environmentObject(self.authViewModel) } } } and consumed as @EnvironmentObject private var authViewModel: AuthViewModel&lt;AuthRepositoryImpl&gt; But with this code, the whole concept of having a generic implementation for the auth repository is useless, because changing the AuthRepostory will need to search and replace AuthViewModel&lt;AuthRepositoryImpl&gt; across all the app. I've experienced this directly creating a MockAuthImpl to use with #Preview, and the preview crashed because it defines AuthViewModel(repository: MockAuthImpl()) but the view expects AuthViewModel. There is a better way to do that?

Given a sheet with [.medium] detents, that contains a native ColorPicker in SwiftUI: struct SheetView: View { @State var color: Color = .white var body: some View { ColorPicker( "Color", selection: $color, supportsOpacity: false ) .padding() } } struct ContentView: View { @State var isSheetOpen = false var body: some View { Button("Open Sheet") { isSheetOpen = true } .sheet(isPresented: $isSheetOpen) { SheetView() .presentationDetents([.medium]) } } } When I tap the ColorPicker's color indicator button, it presents the color picker sheet with a layout glitch. During the color picker presentation animation, the original sheet (SheetView) is rapidly pushed up and back down. It is a wild guess but I think it has to do something with keyboard avoidance. Unfortunately, this makes it impossible to use the picker in my app....

As you can see in the screenshot, the verification popups that appear when making a StoreKit purchase cut off the buttons. When typing the code into the input field, the window will also flicker and stutter with random view refreshes. Is this something I can configure/change? It's not a very pleasant experience for making an in app purchase.

The SwiftUI Playground code below demonstrates that a .jpeg image can be read and written to the iOS file system. While, a.png image can only be read; the writing request appears to be ignored. Can anyone please tell me how to code to save a .png image using SwiftUI to the iOS file system. Code: import SwiftUI import UniformTypeIdentifiers /* (Copied from Playground 'Help' menu popup.) UIImage Summary An object that manages image data in your app. You use image objects to represent image data of all kinds, and the UIImage class is capable of managing data for all image formats supported by the underlying platform. Image objects are immutable, so you always create them from existing image data, such as an image file on disk or programmatically created image data. An image object may contain a single image or a sequence of images for use in an animation. You can use image objects in several different ways: Assign an image to a UIImageView object to display the image in your interface. Use an image to customize system controls such as buttons, sliders, and segmented controls. Draw an image directly into a view or other graphics context. Pass an image to other APIs that might require image data. Although image objects support all platform-native image formats, it’s recommended that you use PNG or JPEG files for most images in your app. Image objects are optimized for reading and displaying both formats, and those formats offer better performance than most other image formats. Because the PNG format is lossless, it’s especially recommended for the images you use in your app’s interface.

Is there any way to change the height of the "day" cells in the UICalendarView? The view is very tall on the screen and I'd like to shorten it so I can put more content below it without using a scroll view. I'm using SwiftUI with a UICalendarView with UIViewRepresentable. The calendar will have default decorations to indicate a date with events.

macOS: 15.0 macFUSE: 4.8.3 I am using rclone + macFUSE and mount my netdisk where it has created three subdirectories in its root directory: /user, /share, and /group. When I save a file to /[root]/user using NSSavePanel and name it test.txt, I expect the file to be saved as: /[root]/user/test.txt However, occasionally, the delegate method: - (BOOL)panel:(id)sender validateURL:(NSURL *)url error:(NSError **)outError { } returns an incorrect path: /[root]/test.txt This issue only occurs when selecting /user. The same operation works correctly for /share and /group. Is there any logs I could provide to help solving this issue? Many thanks!

I'm getting the following error in my SwiftUI code: "Main actor-isolated property 'avatarImage' can not be referenced from a Sendable closure" I don't understand how to fix it.

My app uses the SwiftUI Map control to display annotations. When annotations contain buttons AND the map has an .onTapGesture modifier, annotation button taps aren’t always recognized. Given the following ContentView, run it on an iOS device or simulator. Tap the buttons. Since iOS 18.0, some of the buttons won't respond to tap. I've also tried using the onTapGesture instead of a button, and that shows the same issue. This was not a problem under iOS 17.x: it has only shown up for my users since updating to iOS 18. Additionally, this issue does not occur when running on either macOS 15.0 or visionOS 2.0 when running in "designed for iPad" mode. Note that there was previously a tap issue on VisionOS 1.x (designed for iPad), where no tap gestures were received by annotations. I'm curious if this issue could be related. I have filed a report in Feedback Assistant (FB15273909). struct ContentView: View { private let center = CLLocationCoordinate2D(latitude: 37.77925, longitude: -122.41924) @State private var label: String = "tap a button" @State private var locations: [Location] = [] var body: some View { Map { ForEach(locations) { location in Annotation(location.name, coordinate: location.coordinate) { Button(location.name) { print("\(location.name) tapped") label = "\(location.name) tapped" } .buttonStyle(.borderedProminent) } .annotationTitles(.hidden) } } .onTapGesture { point in print("Map tapped") label = "map tapped" } .safeAreaInset(edge: .top) { Text(label) .padding() .background(.thinMaterial) .clipShape(.rect(cornerRadius: 10)) } .navigationTitle("Test Page") .navigationBarTitleDisplayMode(.inline) .task { for index in 1...16 { locations.append(Location(name: "location \(index)", coordinate: CLLocationCoordinate2D(latitude: center.latitude + Double.random(in: -0.02...0.02), longitude: center.longitude + Double.random(in: -0.02...0.02)))) } } } private struct Location: Identifiable { let id: UUID = UUID() let name: String let coordinate: CLLocationCoordinate2D } } #Preview { ContentView() }

I'm creating an app which gamifies Screen Time reduction. I'm running into an issue with apples Screen Time setting where the user can disable my apps "Screen Time access" and get around losing the game. Is there a way to detect when this setting is disabled for my app? I've tried using AuthorizationCenter.shared.authorizationStatus but this didn't do the trick. Does anyone have an ideas?

I have a UITextField with UITextContentType equal to oneTimeCode. It works as expected if the message is in English and the keyword "OTP" exists. It doesn't work if the message is in Greek and the keyword "OTP" is translated also in greek. Is the OTP keyword really needed? Is there any alternative? Which are the keywords for any case? Are these keywords only in English? Thanks in advance!
