I have an infinite week scroller implemented using a TabView's page styling. basically when you scroll to the next week, it pre-loads the week after so that you can scroll infinitely. Since iOS 17.4, it seems to partially scroll two pages ahead. Scrolling backwards works fine. I made a radar: FB13718482 Here is a simplified implementation that has the issue reproduced. It uses the swift ordered collections library. Video of the issue: https://youtu.be/JW8dHqawURA import Foundation import OrderedCollections import SwiftUI struct ContentView: View { private let calendar: Calendar private let dateFormatter: DateFormatter @State var weeks: OrderedDictionary @State var selectedWeek: WeekView.Week.ID init() { let calendar = Calendar.autoupdatingCurrent self.calendar = calendar let formatter = DateFormatter() formatter.calendar = calendar formatter.dateFormat = MMM d dateFormatter = formatter // Setup initial week let currentDate = Date() let weekIdentifier = Self.weekIdentifier(for: currentDate, calendar: calendar)

Hi, I wrote the code below to demonstrate an issue I cannot handle, since I am very new to swiftui struct Cell: Identifiable { var id: UUID = UUID() var i: Int = 0 init(i: Int) { self.i = i } } struct ContentView: View { var columns: [GridItem] = [GridItem](repeating: GridItem(.fixed(40), spacing: 5), count: 60) var cells: [Cell] = [] init() { cells.removeAll() for i in 0..<180 { cells.append(Cell(i:i)) } } var body: some View { ScrollView([.horizontal, .vertical]) { LazyVGrid(columns: columns, spacing: 5) { ForEach(cells) { cell in ButtonView(cell: cell) } } } } } struct ButtonView: View { var cell: Cell @State var popOver: Bool = false var body: some View { Button { popOver.toggle() } label: { Text((cell.i)) } .popover(isPresented: $popOver, content: { Text(Information line of button (cell.i)).padding() }) } } #Preview { ContentView() } Running the code above, button clicks are not always work

Hi, i want to place a object in 3d world space without the use of hittest or plane detection in ios swift code. Suggest the best method. Now, I take the camera center matrix and use simd_mul to place the object, it works but the object gets placed at the centre of the mobile screen. I want to select the x and y positino on the screen 2d coordinate and place the object. I tried using the unprojectpoint function, to get the AR scene world coordinate of the point i touch on the mobile screen. I get the x, y,z values, they are very close to the values from camera center matrix. When i try to replace the unprojectpoint values in the cameracenter matrix, i dont see a difference in the location of the placed object. The below code always place object from center screen with specified depth, But i need to place object in user specified position(x,y) of the screen with depth. 2D pixel coordinate system of the renderer to the 3D world coordinate system of the scene. /* Create a transform with a translation of 0.2 meter

Dear all, I'm quite new to SwiftUI and I'm trying to build my first app. I have a data model file like the one below (I'm just posting a portion of it): import Foundation struct CalendarioPartite: Identifiable, Hashable, Equatable { let id = UUID() let stagione: String let giornata: Int let datapartita: String let squadracasa: String let golsquadracasa: Int let squadratrasferta: String let golsquadratrasferta: Int init(stagione: String, giornata: Int, datapartita: String, squadracasa: String, golsquadracasa: Int, squadratrasferta: String, golsquadratrasferta: Int) { self.stagione = stagione self.giornata = giornata self.datapartita = datapartita self.squadracasa = squadracasa self.golsquadracasa = golsquadracasa self.squadratrasferta = squadratrasferta self.golsquadratrasferta = golsquadratrasferta } static func testCalendario() -> [CalendarioPartite] { [CalendarioPartite(stagione: 2023/2024, giornata: 1, datapartita: 04/09/2023, squadracasa: Castelnovese Castelnuovo, golsquadracasa: 1, squadratrasferta: J

All examples regarding SwiftUI Tables and sorting work fine, but they also have all the data available immediately. If I load the data in .task, sorting only works on the first column. Test data: struct Customer: Identifiable { let id = UUID() let name: String let email: String let creationDate: Date } func parseDate(from text: String) -> Date { let formatter = DateFormatter() formatter.dateFormat = dd/MM/yyyy return formatter.date(from: text) ?? Date() } func getTestData() -> [Customer] { return [ Customer(name: John Smith, email: john.smith@example.com, creationDate: parseDate(from: 04/11/2015)), Customer(name: Jane Doe, email: jane.doe@example.com, creationDate: parseDate(from: 29/04/2009)), Customer(name: Bob Johnson, email: bob.johnson@example.com, creationDate: parseDate(from: 01/08/2010))] } And here the view: table 1 populates the array in the initializer table 2 loads the content in .task, initially it is empty table 3 loads the content in .task, initially it contains one dummy object

I am trying to get SwiftUI views to move from one position to another using animation. I know that when the identity of the views change this often result in a fade instead of an animation but I do not believe this is happening in my case. Below is a simple example program with four views from a 2D array (the 2D array is important). There is a button to rotate the views clockwise. I tried using two ForEach blocks but I cannot use it on the outer one because the row arrays does not conform to Identifiable. I also changed my code to write out the views explicitly without the ForEach blocks but I get the same result: The column changes animate as movement but the row changes animate as fades. How do I get it to animate all four views moving clockwise? import SwiftUI struct Block: Identifiable { var id : Int = 0 } struct Board { let numRows = 2 let numCols = 2 var blocks: [[Block]] init() { blocks = Array(repeating: Array(repeating: Block(), count: numCols), count: numRows) for row in 0..

We're trying to implement a file locking mechanism to prevent multiple users from editing the same file at the same time causing conflicts. Our previous implementation worked well on Ventura, but on Sonoma, even when just previewing a file in Finder in Column View, as opposed to editing, it locks. This is the same behaviour we experienced with Apple's FruitBasket sample code. There is a isFileViewerRequest flag inside the NSFileProviderRequest object provided with the NSFileProviderReplicatedExtension enumerator function. We thought this would indicate a file being edited. After further investigation, we were told that the isFileViewerRequest flag just indicates if a file is being presented, not just edited. We find the intended behaviour a bit strange, why would anyone want an icon next to a file to indicate presented? Why is the behaviour working fine on Ventura as a locking mechanism but on Sonoma it can only be considered a presented mechanism? If the intended behaviour is to indicate a file bein

In WWDC2020, the video Synchronizing a local store to the cloud shows some data fields in the left column of the dashboard, such as CD_post, CD_Tag, where did these come from? need to create it manually on dababoard, or it synchronize from the demo app ? why do I run this corresponding demo, but there are no data fields in the dashboard of my account and my dashboard of my account is almost empty?

With the deprecation of the airport binary in macOS 14.4 I am re-writing my own network tool to directly use CoreWLAN. In doing this and testing and comparing to previous results from the Apple airport binary under various versions of macOS I believe CoreWLAN has a 'bug' which as a result was exhibited in the Apple airport binary and equally my own code. As detailed below. This applies to the release version of macOS 14.4 (23E214) macOS Sonoma 14.3.1 and previous versions of macOS going back many, many years have included an official Apple binary at the following location. /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport Whilst this is now officially deprecated in macOS 14.4 it is obvious that this tool will have itself been utilising the official Apple framework CoreWLAN. As part of the process of re-writing my own tool which formerly used the above Apple binary, I have re-written my tool to directly utilise CoreWLAN myself via the Objc interface. In doing this I have been
