“column”

Having a traditional 'NavigationSplitView' setup, I am looking for a way to animate it the same as the sidebarView, where there is a button to toggle and it animates by sliding out from the right side of the view, however the closest I have gotten was manipulating the 'navigationSplitViewColumnWidth' but that always results in the view instantly appearing / disappearing. I am using SwiftUI for a MacOS specific app. Here is just a general idea of what I am currently doing, it is by no means a reflection of my real code but serves the purpose of this example. struct ContentView: View { @State private var columnWidth: CGFloat = 300 var body: some View { NavigationSplitView { List { NavigationLink(destination: DetailView(item: Item 1)) { Text(Item 1) } NavigationLink(destination: DetailView(item: Item 2)) { Text(Item 2) } NavigationLink(destination: DetailView(item: Item 3)) { Text(Item 3) } } .navigationTitle(Items) } detail: { VStack { DetailView(item: Select an item) Button(action: toggleColumnWidth) { Text(co

Helo all, Currently, I'm working on an iOS app that performs measurement and shows the results to the user in a graph. I use a Savitzky-Golay filter to filter out noise, so that the graph is nice and smooth. However, the code that calculates the Savitzky-Golay coefficients using sparse matrices crashes sometimes, throwing an EXC_BAD_ACCESS. I tried to find out what the problem is by turning on Address Sanitizer and Thread Sanitizer, but, for some reason, the bad access exception isn't thrown when either of these is on. What else could I try to trace back the problem? Thanks in advance, CaS To reproduce the error, run the following: import SwiftUI import Accelerate struct ContentView: View { var body: some View { VStack { Button(Try, action: test) } .padding() } func test() { for windowLength in 3...100 { let coeffs = SavitzkyGolay.coefficients(windowLength: windowLength, polynomialOrder: 2) print(coeffs) } } } class SavitzkyGolay { static func coefficients(windowLength: Int, polynomialOrder: Int, derivativeOr

I have a Matrix structure as defined below for working with 2D numerical data in Accelerate. The underlying numerical data in this Matrix struct is stored as an Array. struct Matrix { let rows: Int let columns: Int var data: [T] init(rows: Int, columns: Int, fill: T) { self.rows = rows self.columns = columns self.data = Array(repeating: fill, count: rows * columns) } init(rows: Int, columns: Int, source: (inout UnsafeMutableBufferPointer) -> Void) { self.rows = rows self.columns = columns self.data = Array(unsafeUninitializedCapacity: rows * columns) { buffer, initializedCount in source(&buffer) initializedCount = rows * columns } } subscript(row: Int, column: Int) -> T { get { return self.data[(row * self.columns) + column] } set { self.data[(row * self.columns) + column] = newValue } } } Multiplication is implemented by the functions shown below. import Accelerate infix operator .* func .* (lhs: Matr

We have a feature requirement where we need to use LazyVGrid and DropDelegate. Our view hierarchy is as follows: Color.white.ignoresSafeArea() VStack(spacing: 0) { customNavigationView ScrollView(showsIndicators: true) { LazyVGrid(columns: columns, alignment: .center, spacing: 16) { ForEach(viewModel.selectedReferences, id: .self) { item in ZStack { Rectangle() .fill(Color.yellow.opacity(0.5)) Text(item.title) } .frame (height: 120) .background(Color.white) .padding([.leading, .trailing], 4) .overlay((draggedItem?.uuid == item.uuid && changedView) ? Color.white.opacity(0.8) : Color.clear) .clipShape(RoundedRectangle(cornerRadius: 16, style: .continuous)) .onDrag { initialIndex = viewModel.selectedReferences.firstIndex { $0 == item } draggedItem = item changedView = false return NSItemProvider(object: String(item.uuid) as NSString) } .clipShape(RoundedRectangle(cornerRadius: 16, style: .continuous)) .onDrop(of: [UTType.text], delegate: DragRelocateDelegate(item: item, listData: $viewM

I am writing an Library app that shows a grid. Each grid location shows the book cover and some info about the book. If the user clicks on a cover, the detail view opens. One option that the user has is a delete the book button. This button deletes the book from SwiftData, but the detail page remains populated. The simple way I want to handle this is to have the delete button also return to the grid view (eg root). Here is the relative code from the CurrentView @State private var path = [Book]() var body: some View { NavigationStack(path: $path) { BookListView(sort: sortOrder, searchString: searchText) .navigationTitle(Library) .navigationDestination(for: Book.self, destination: EditBookView.init) .searchable(text: $searchText) Here is the code from the Grid View var body: some View { LazyVGrid (columns: gridLayout) { ForEach(books) { book in NavigationLink(value: book) { GridRow { VStack { Here is the code from the Detail View var body: some View { Form { VStack (spacing: 0){ BookImageView(book: boo

Hi, i have an old popover status bar mac app that i didn't check in the past few macOS releases, so don't know when the problem appeared. On Sonoma i have the following problem: All NSTableViews cells when they are reused the second time, they are blank. The cells are of type view and only one column. If i investigate in the Xcode's view hierarchy I indeed see no subviews in the cell, but if i print the subviews and their frames and their visibility, they are there alright, they exist. All the cells are instantiated from nib and I tried few strategies to use them: register the cell in the tableview and load it with tableView.makeView(withIdentifier: ) no registration, just load them from xib and keep a reference to their instance and feed that to the table when asked no registration, load them from xib when the table asks. This solution actually works but i really need a reference to them that doesn't change, it's a settings screen and someone else is feeding some info to this cells. I'm stuck, I hav

&TLDR; I see no documentation stating that during the life of UISplitViewController, that I cannot call setViewController(xxxxx, column) more than once on the same column. Yet in my experience calling it a second time does not work, unless I set the value to nil before calling it again to set it to the new value... I'm using a UISplitViewController in newer column-style layout and when bootstrapping the app, I create the UISplitViewController and use setViewController(primaryViewController, .primary) and setViewController(detailViewController, .secondary). In order to use the primaryViewController for the compact scenario, I return the .primary column in the UISplitViewControllerDelegate method: splitViewController(_ svc: UISplitViewController, topColumnForCollapsingToProposedTopColumn proposedTopColumn: UISplitViewController.Column) -> UISplitViewController.Column Tapping a cell in the primaryViewController, results in a call to splitViewController.show(.secondary)

I have a document app built using SwiftData because frankly I'm too lazy to learn how to use FileDocument. The app's title is Artsheets, and I'm using a document type that my app owns: com.wannafedor4.ArtsheetsDoc. The exported type identifier has these values: Description: Artsheets Document Identifier: com.wannafedor4.ArtsheetsDoc Conforms to: com.apple.package Reference URL: (none) Extensions: artsheets MIME Types: (none) And the code: ArtsheetsApp.swift import SwiftUI import SwiftData @main struct ArtsheetsApp: App { var body: some Scene { DocumentGroup(editing: Sheet.self, contentType: .package) { EditorView() } } } Document.swift import SwiftUI import SwiftData import UniformTypeIdentifiers @Model final class Sheet { var titleKey: String @Relationship(deleteRule: .cascade) var columns: [Column] init(titleKey: String, columns: [Column]) { self.titleKey = titleKey self.columns = columns } } @Model final class Column: Identifiable { var titlekey: String

Context menu on tvOS LazyVGrid selecting wrong item. It works fine if selecting items on last row. Testing on code from https://developer.apple.com/videos/play/wwdc2024/10207/ I just added contextMenu LazyVGrid(columns: columns, spacing: 40) { ForEach(sortedMatchingAssets) { asset in Button {} label: { asset.landscapeImage .resizable() .aspectRatio(16 / 9, contentMode: .fit) .contextMenu { Button(Test) {} } Text(asset.title) } .buttonStyle(.borderless) } } Attached video with the bug - https://www.icloud.com/iclouddrive/020zq2PxZ_E_1Pr0vE86-8aww#Screen_Recording_2024-06-13_at_9.26.15%E2%80%AFPM

When I trusted my certificate in 'Setting'->'VPN & Device Management', my device reboot automatically. After reboot, it showed that developer of My Team is not trusted in this iPhone, but the app is verified in the second column. The UI looks like: iOS18 beta: First Col: Trust My Team Second Col: MyApp Verified Other versions: First Col: Delete App Second Col: MyApp Verified What's more, my app has plugins(extensions), my app can run normally while the extension is not able to be pulled up on iOS18 beta.

In Xcode (Mac OS Catalina), when trying to create an application to access a database, I receive syntax errors, resulting from the installed version of SQlite (below 3.30) does not allowing generation of virtual columns. After updating to 3.46 the version installed on system, this does not occur if I execute such queries directly in SQlite, via Terminal. How do I get Xcode to access and use the system updated version ? Thanks in advance
