I'm reworking my app and update code and design. Because my app is one both iPhone and iPad, i'm using Splitview to handle the configurations. But my app has 4 section that I manage using a Tab bar and each tab has a SplitView. As you can see in images, the problem is that if I attach directly the UISplitViewController to UITabBarController you don't see two columns but only one (the primary or secondary view) both iPhone landscape orientation and iPad. A solution that I found is to attach the splitviewcontroller to a view that contains a ContainerViewController e connect the split view to this container. If you do this, you see the split view work correctly ma the problem is the customization of appearance (look at image 3) So may questions are: why I have to embed a split view in a container view controller and i can't connect it directly to tabbar as we done until now? Is there an other better solution then put a split view in a containerView? Thank you )

I am using the following code to create a texture atlas at runtime using a single .png image sprite sheet: func createSpriteTextureAtlas(atlasNumber atlas:Int, forWorld world:Int) { //load the png file let image = UIImage(named: world(world)_spritesheet(atlas)_2048x2048.png) //create the dictonary var imageDictionary = [String: UIImage]() //iterate through all rows and columns and get the subimage var imageIndex = 0 for row in 0...7 { for column in 0...7 { let sourceRect = CGRect(x:column * 256, y:row * 256, width:256, height:256) let sourceImage = image?.cgImage!.cropping(to: sourceRect) let subImage = UIImage(cgImage: sourceImage!) //add the sub image and name to the dictionary imageDictionary[(imageIndex)] = subImage imageIndex = imageIndex + 1 } } //create the texture atlas using the dictionary spriteTextureAtlas[atlas] = SKTextureAtlas(dictionary: imageDictionary) } I have a different sprite sheet for every world. I made all the sprite sheets myself using the same tool. This code works

When I view processes in Activity Monitor's All Processes, Hierarchical view, it shows which processes launched other processes. For instance, if I have Network open inside System Preferences, then when I expand System Preferences, I see (irrelevant columns omitted):Process NamePIDSystem Preferences22033 com.apple.preference.network.remoteservice22043I.e. Activity Monitor knows that remoteservice was created by System Preferences.However, when I use 'ps' from the command line, both processes' parent PID values are 1 (launchd):$ ps -ww -o 'pid,ppid,command' -p 22033,22043PIDPPIDCOMMAND220331/Applications/System Preferences.app/Contents/MacOS/System Preferences220431/System/Library/PreferencePanes/Network.prefPane/Contents/XPCServices/com.apple.preference.network.remoteservice.xpc/Contents/MacOS/com.apple.preference.network.remoteservicesysctl(kern.proc.pid) is the same.How can I learn that remoteservice (pid 22043) was created by System Preferences (pid 22033)?This is OS X Yosemite 10.10.5, but I beli

I'm trying to use the Xcode 15.0 beta on macOS 13.4 (22F66) on a MacBook Pro 16 (2019) but whenever I try to start a new project, Xcode becomes unresponsive – seemingly indefinitely. In Activity Monitor I see Open and Save Panel Service (Xcode) (Not Responding): Even if I try to use Xcode 14.3.1 now I get the same problem. I've tried to resolve this by removing all Xcode-related files as well as the Xcode command line tools and reinstalling them but to no avail. I'd appreciate any and all help in how to fix this. EDIT: I have since found out that if I force-quit the bird process, Xcode will react again. But the bird process will start up and shoot to the top of the % CPU l column in Activity Monitor again almost instantly. It appears to be iCloud-related but I don't know what's causing it to take up so much CPU resources and make Xcode unresponsive, and how I can fix this.

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

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)

I see in CKError.h there is an error: CKErrorConstraintViolation.Is there a way to specify a unique constraint for a column in a CloudKit record?The only part of a CloudKit record that enforces uniqueness as far as I can is recordName (which is specified via CKRecordID). This has limitations though. One being recordName must be 255 characters or less. For the most part, using user input on some field which must be unique in a user created record can be used as a record name to ensure uniqueness. In most cases, this will be under 255 characters but not always though.During testing, I'm just using a hash string for the record name, which will fit in 255 characters:NSString *someStringThatRepresentsUniqueValue = //... NSString *ckRecordName = [NSString stringWithFormat:@%lu,someStringThatRepresentsUniqueValue.hash];But my concern with this is if that the implementation of hash could change in an OS update. Yea, I could hash myself, but my question still stands: is there no way to just make a unique cons

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've put together a simplified code example to test how the location of dropDestination works within a Grid View. When I attach dropDestination to Grid, GridRow or the Text((row) , (column)) view, I get a CGPoint corresponding to the drop location within the views coordinate space. But the problem is how would I get the either the index of a grid cell eg. (1, 1) or the grid cell view itself? Apple's documentation regarding drag and drop in SwiftUI says to prefer using transferable items which I interpret as them recommending dropDestination over the older onDrop with an NSItemProvider. But unlike in a List view there doesn't seem to be away for location to return discrete values. If I instead attach dropDestination to a one of the nested ForEach loops within the Grid view, the drop gesture doesn't do anything? Also dropDestination exhibits some default behaviour that I don't want. When dragging a view a little plus symbol within a green circle appears Views can be dragged and dropped out of the apps

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
