“column”

Hi all, I've been struggling a bit with SwiftData, I have a really simple data model but I need to do a fairly complex query over a one-to-many relationship that results in aggregate values. And I want to be able to sort and filter those aggregates. The model looks like this: @Model class Category { var name: String var items = [Item]() } @Model class Item { var added: Date var checked: Date? } In a typical use case I'd expect their to be at most around 50 categories and perhaps 20 items per category. In my UI I would like to be able to sort categories in a couple of ways: by name, by date added and by date checked with a fallback on date added. Also, in my list view I want to be able to list categories and show the checked date of the most recently checked item. I can think of a couple of solutions here, to start of with I can do all the sorting and filtering client-side. In the list view I could retrieve all the categories and then find the most recently checked item per category and go from there. Another

My MacOS app only cares about days, not time-of-days, so I made a simple Date Extension: extension Date { static func ==(lhs: Date, rhs: Date) -> Bool { let order = Calendar.current.compare(lhs, to: rhs, toGranularity: .day) return (order == .orderedSame) } } My app compiles fine and works as intended. However, #Preview is failing to build the preview, erroring with: CompileDylibError: Failed to build DayRow.swift Compiling failed: ambiguous use of operator '==' @__swiftmacro_45test_calendarview_PreviewReplacement_DayRow_133_EA4566EE578D744A3A6BCC599B1B43AALl0C0fMf_.swift ------------------------------ @available(iOS 17.0, macOS 14.0, tvOS 17.0, watchOS 10.0, xrOS 1.0, *) struct $s45test_calendarview_PreviewReplacement_DayRow_133_EA4566EE578D744A3A6BCC599B1B43AALl0C0fMf_15PreviewRegistryfMu_: DeveloperToolsSupport.PreviewRegistry { static let fileID: String = test_calendarview_PreviewReplacement_DayRow_1/DayRow.1.preview-thunk.swift static let line: Int = 160 static let column: Int = 1 static func

Hello, I'm developing an app for Mac, Xcode 15.1, with Swift 5. I need to create a visual matrix, whose elements will be filled randomly, according to the choices the user makes. The matrix must have 10 columns and 40 rows. Does anyone know a component, or how to fill it dynamically and randomly? Thanks.

I have a table view where each row has two labels, one left-aligned and one right-aligned. I would like to reload a single row, but doing so causes the right-aligned label to hug the left-aligned label. Before the reload: After the reload: Reloading the whole table view instead, or disabling automatic row height, solves the issue. Can a single row be reloaded without resorting to these two workaround? class ViewController: NSViewController, NSTableViewDataSource, NSTableViewDelegate { override func loadView() { let tableView = NSTableView() tableView.translatesAutoresizingMaskIntoConstraints = false tableView.dataSource = self tableView.delegate = self tableView.usesAutomaticRowHeights = true let column = NSTableColumn() column.width = 400 tableView.addTableColumn(column) let scrollView = NSScrollView(frame: CGRect(x: 0, y: 0, width: 500, height: 500)) scrollView.translatesAutoresizingMaskIntoConstraints = false scrollView.documentView = tableView view = scrollView Timer.scheduledTimer(withT

like Table(viewModel.rows, selection: $selection) { ForEach(viewModel.columns, id: .self) { column in TableColumn(column, value: { row in Text(row[column] as? String ?? ) }) } }

I have an iPhone 11 (MWJE2LL/A) for personal and development use. When I upgraded it to iOS 17.2.1 it stopped sync'ing to my computers. I can't sync or restore the iPhone. Both Finder and Music show the iPhone in the left column, but time out after 60 secs of Loading..., finally stating: The selected device could not be found. Xcode also does not see the connected iPhone, and does not list it in the available iOS build destinations. I have tried sync'ing using numerous Apple USB cables and computers (Mac Pro, 16 MacBook Pro, Mac Studio) all running macOS Sonoma 14.1. Is this a known bug in iOS 17.2? Is there a workaround so I can restore the iPhone and continue development work?

It looks like there's a new tab bar / column style design for tvOS that was introduced with the current TV app. Is there any word on this being a developer available component?

Hi all, I am new to Swift and I have found an issue which I can't fix. I use a TabView and if I change the views a few times, and go back to this view I get this error and I can't tab on any of the views any longer in the Navigation Stack. The way to fix it, is to force close the app and reopen it. Error message: A NavigationLink is presenting a value of type “NavigationItem” but there is no matching navigationDestination declaration visible from the location of the link. The link cannot be activated. Note: Links search for destinations in any surrounding NavigationStack, then within the same column of a NavigationSplitView. Code: struct ToolsMainView: View { @State private var navigationPath = NavigationPath() var body: some View { NavigationStack(path: $navigationPath) { VStack { ScrollView(showsIndicators: false) { VStack { ForEach(navigationItems) { item in NavigationLink(value: item) { HStack(alignment: .center, spacing: 12) { Image(systemName: item.icon) Text(item.title) Spacer() Image(systemNa

HStack { ForEach(days, id:.self) { day in Text(day) .font(.system(size: 12, weight: .medium)) .frame(maxWidth: .infinity) } } LazyVGrid(columns: Array(repeating: GridItem(.flexible()), count: 7), spacing: 20) { ForEach(fetchDates()) { value in ZStack { if value.day != -1 { let hasAppts = manager.days.contains(value.date.monthDayYearFormat()) NavigationLink(value: AppRouter.day(date: value.date)) { Text((value.day)) .foregroundColor(hasAppts ? .blue : .black) .fontWeight(hasAppts ? .bold : .none) .background { ZStack(alignment: .bottom) { Circle() .frame(width: 48, height: 48) .foregroundColor(hasAppts ? .blue.opacity(0.1) : .clear) if value.date.monthDayYearFormat() == Date().monthDayYearFormat() { Circle() .frame(width: 8, height: 8) .foregroundColor(hasAppts ? .blue : .gray) } } } } .disabled(!hasAppts) } else { Text() } } .frame(width: 32, height: 32) } } } .padding() }

I embedded a vertical scrollview to a calendar that was originally horizontally navigation with buttons. But its isn't scrolling changing months. What am I missing? let days = [SUN, MON, TUE, WED, THU, FRI, SAT] @State private var selectedMonth = 0 @State private var selectedDate = Date() @State private var path = NavigationPath() var body: some View { NavigationStack(path: $path) { ScrollView { VStack { Rectangle() .frame(height: 1) .foregroundColor(.gray) VStack(spacing: 20) { // Month Selection HStack { Spacer() Button { withAnimation { selectedMonth -= 1 } } label: { Image(systemName: lessthan.circle.fill) .resizable() .scaledToFit() .frame(width: 32, height: 32) .foregroundColor(.gray) } Spacer() Text(selectedDate.monthYearFormat()) .font(.title2) Spacer() Button { withAnimation { selectedMonth += 1 } } label: { Image(systemName: greaterthan.circle.fill) .resizable() .scaledToFit() .frame(width: 32, height: 32) .foregroundColor(.gray) } Spacer() } HStack { ForEach(days, id:.self) { day in Text(day) .font

Hi, I've tried to find a solution for this problem for weeks now but it seems no one knows how to solve it and Apple doesn't seem to care. I have a NavigationSplitView with two columns. In the detail column I have a button - or any other clickable control - which is placed in the very top where usually the safe area resides. The button is NOT clickable when he is in the safe area and I have NO idea why. I know I can place buttons in safe areas of other views and they are clickable. Please have a look at the code: `struct NavTestView: View { var body: some View { GeometryReader { p in VStack(spacing: 0) { NavigationSplitView { List(names) { Text($0.name).frame(width: p.size.width) .background(Color.green) }.listRowSpacing(p.size.height * 0.15 / 100 ) .toolbar(.hidden, for: .navigationBar) } detail: { TestView().ignoresSafeArea() }.frame(width: p.size.width, height: p.size.height, alignment: .topLeading) .background(Color.yellow) } } } } struct TestView: View { var body: some View { GeometryRe
