column

Hi there, I'm working on an app that provides the user a prompt. They have to select the matching button. These butttons are created in three separate rows using three forEach loops acting on a customised button made from a Struct. ForEach(0..<10) { column in AlphabetButton( gameViewModel: gameViewModel, letter: String(alphabetTop[column]), borderColor: $borderColor.wrappedValue, onTap: buttonTapped) }} alphabetTop is an array storing letters used as the buttons label and value, and there are two other arrays with the other letters. What I'm wondering, is if the user presses a button that doesn't match the prompt. How can I make reference to the button that does match the prompt. For example, I want to make the border of that correct button flash Orange if the wrong button is pressed. I am making a keyboard app as a bit of practise in learning SwiftUI, so any assistance you can provide would be most helpful. One potential solution I've thought of, do I make the buttonTapped function, chec

Hi guys, please help me with sqlite database. When I save the data in the table, it always saves the wrong data in the columns. They don't match the submitted data at all. I don't know where I am making a mistake. Thank you! DatabaseManager ViewController

I am currently trying to build a NavigationManager with programmatic navigation. For that I'm using the NavigationPath combined with NavigationDestination. Sadly facing the following issue: navigationDestionation is not being recognised when located in sheet. Im receiving the following message when trying to update the path of the NavigationStack within the sheet. A NavigationLink is presenting a value of type “PathType” 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. Here is some simplified code snipped of the implementation. struct RootView: View { @State private var isPresented: Bool = true var body: some View { Button(Open Modal, action: { self.isPresented.toggle() }) .sheet(isPresented: self.$isPresented, content: { ModalContent() }) } } private struct ModalContent: View { @State private var p

When I used Context Menu for each photo in three columns. So, the code is like below: List { LazyVGrid(columns: columns) { View() .contextMenu { Button() } } } This just pop up whole list not individual element when I long press the element to see context menu. The whole list is highlighted when context menu appears. How can I make this to highlight individual element not the whole list? If I remove any of List or LazyVGrid the problem fix. But the columns are not in the way I want. Also, I don't want to change List to VStack or ScrollView which don't have refreshControl. Thanks in advance.

I did a very simple test using Metal PerformanceShaders. It is basically a MPSMatrixMultiplication.I compiled it in Terminal with 'swiftc matrixMul.swift'Then you get the executable called matrixMul.Now, execute 'time matrixMul' and after approximately 10 seconds you will get the first then elements of the result matrix prows i/nted on screen.This all works as intended, however I realized in Activity Monitor (and also because of high GPU fan speed), that somehow the GPU isn't fully released. The Activity Monitor through the GPU monitor shows 100% activity for several minutes anfter program exit. Somehow the matrixMul process keeps the GPU busy after program exit. Do I miss some statement in my code which tells the system to free resources?Below is the simple test-code------------------------------------- import Metal import Accelerateimport MetalPerformanceShaderslet n = 8192let rowsA = nlet columnsA = nlet rowsB = nlet columnsB = nlet rowsC = nlet columnsC = nvar arrayA = [Float](repeating: 1, count: rowsA *

Hi, colleagues: I've spent days trying to understand this little SwiftUI layout problem, and I've made a minimal test app to explain it. It's based on a Content View of a fixed size. import SwiftUI @main struct TestApp: App { var body: some Scene { WindowGroup { ContentView() } .windowResizability(.contentSize) .windowToolbarStyle(.unified(showsTitle: false)) } } struct ContentView: View { let complaint = What's with the vertical space around me when I'm in a detail column? var body: some View { Text(complaint) .font(.title) .frame(width: 300, height: 300) .background(.blue) } } And here's the result. As expected, the Content View is hugged nicely by the window: My goal is to place a fixed-size view like this in the detail column of a Navigation Split View. So I update the scene's root view: import SwiftUI @main struct TestApp: App { var body: some Scene { WindowGroup { NavigationSplitView( sidebar: { }, detail: { ContentView() } ) } .windowResizability(.contentSize) .windowToolbarStyle(

I was following the tutorial video to implement arrow key navigation on a LazyVGrid. (starting at 18:50: https://developer.apple.com/videos/play/wwdc2023/10162/?time=1130) In the code tab there is a full code sample but it omits the part where the MoveCommandDirection actually determines what the next grid items to select is. private func selectRecipe( _ direction: MoveCommandDirection, layoutDirection: LayoutDirection ) { // ... } Considering that the LazyVGrid actually uses an adaptive layout, what is the correct way to determine the GridItem above or below the current selected GridItem? this is the full example the tutorial provides: struct ContentView: View { @State private var recipes = Recipe.examples @State private var selection: Recipe.ID = Recipe.examples.first!.id @Environment(.layoutDirection) private var layoutDirection var body: some View { LazyVGrid(columns: columns) { ForEach(recipes) { recipe in RecipeTile(recipe: recipe, isSelected: recipe.id == selection) .id(recipe.id) #if

I have an image. The table has many columns and associated rows with it. Is it possible to recognize a particular column's key and values from the table?
