column

My project loads a CSV into a DataFrame and displays it in a Table (a MacOS app). So far so good ... but when trying to update a value in a column, I dont see anyway to update this value. The table gets the value for the column like this: func getColumnValue(row :DataFrame.Rows.Element, columnName :String) -> String { if row.base.containsColumn(columnName) { var value = if row[columnName] != nil { value = (row[columnName]!) } return value } ... But the documentation and googles dont show any way to update the same column. Any help is appreciated with cookies. Attempt to update: func setColumnValue(row :DataFrame.Rows.Element, columnName :String, value :String) { var column: [String?] = data[columnName] column[row.id] = value ... }

Hi I just released an app which is live. i have a strange issue: while the audio files in the app play fine on my device, but some users are unable to hear. One friend said it played yesterday but not today. Any idea why? The files are mp3, I see them in Build Phase, and in the project obviously. Here's the audio view code, thank you! import AVFoundation struct MeditationView: View { @State private var player: AVAudioPlayer? @State private var isPlaying = false @State private var selectedMeditation: String? var isiPad = UIDevice.current.userInterfaceIdiom == .pad let columns = [GridItem(.flexible()),GridItem(.flexible())] let tracks = [Intro:intro.mp3, Peace : mysoundbath1.mp3, Serenity : mysoundbath2.mp3, Relax : mysoundbath3.mp3] var body: some View { VStack{ VStack{ VStack{ Image(dhvani).resizable().aspectRatio(contentMode: .fit) .frame(width: 120) Text(Enter the world of Dhvani soundbath sessions, click lotus icon to play.) .font(.custom(Times New Roman, size: 20)) .lineLimit(nil) .multilineTextA

Hello reader, I am facing an issue that I am not able to resolve. I have been able to create a demo project that demonstrates the issue, which I hope enables you to have a look as well and hopefully find a way to resolve it. What is the issue: I am using SKTileMapNode in order to draw tile maps. Instead of using the tilesets as you can use from within the Xcode editor, I prefer to do it all programmatically using tilesheets (for a plethora of reasons that I will leave out of this equation). This is the code of the gameScene: import SpriteKit import GameplayKit class GameScene: SKScene { private let tileSize = CGSize(width: 32, height: 32) override func didMove(to view: SKView) { super.didMove(to: view) let tileSet = createTileSet() let tileMap = SKTileMapNode(tileSet: tileSet, columns: 100, rows: 100, tileSize: tileSize) for column in 0.. SKTileSet { let tileSheetTexture = SKTexture(imageNamed: terrain) var tileGroups = [SKTileGroup]() let relativeTileSize = CGSize(width: tileSize.width/tile

Hi everyone, I was exploring the Display Distinct Layouts Per Section section of the Apple documentation and noticed a potential issue in the example code provided. Specifically, in the createLayout method of the TwoColumnViewController in the sample project, the item size appears to be incorrectly described. The documentation states that the item size is ignored because the items are organized in columns, but in practice, the size is considered. When running the sample project without any modifications, the layout doesn't behave as described or expected. Here’s what I observed: The items are not displayed as intended in a two-column layout. Modifying the item size explicitly affects the layout, contrary to the documentation's claim that the size is ignored. This seems to be a mismatch between the documentation and the actual implementation. Could this be clarified or corrected? Has anyone else encountered this issue? If so, are there any recommended adjustments to the sample code to achieve

Hello. There seems to be a bug specifically in the iOS 18.2 (both Beta 1 and 2) and not seen in the previous versions. The bug is: when LazyVGrid is nested inside NavigationStack and some elements of the LazyVGrid have animations, navigating into any nested view and then going back to the initial view with the LazyVGrid causes all animations to stop working. Here is the example code inline: struct ContentView: View { @State private var count: Int = 0 var body: some View { NavigationStack { LazyVGrid( columns: Array( repeating: GridItem(spacing: 0), count: 1 ), alignment: .center, spacing: 0 ) { VStack { Text(String(count)) .font(.system(size: 100, weight: .black)) .contentTransition(.numericText()) .animation(.bouncy(duration: 1), value: count) Button(Increment) { count += 1 } NavigationLink(destination: { Text(Test) }, label: { Text(Navigate) }) } } } .padding() } } Once you run the application on iOS 18.2 Beta (I've tried on a real device only), the steps to reproduce are: Tap on the Increment butt

Anyone else notice that Finder no longer shows most photos exif data when in column mode - usually it appears below the photos image.

I've looked at lots of Grid examples. I've seen it documented that views within a GridRow are treated as if they were in an HStack. That's not happening for me. I have to explicitly put them into an HStack or they are treated as new rows. Here's my code: @State private var gridRows : Int = 4 @State private var gridCols : Int = 2 @State private var myItems : [Int] = Array(0...8) var body: some View { Group { if myItems.count > 0 { ScrollView([.vertical]) { Grid(alignment: .leading) { ForEach(0..<<--- { ForEach(0..

Script error. We've decided to implement certain highly-dynamic content in out iOS codebase using web technologies, here's what we're doing: We download a zip file containing html, javascript, and images. We unzip the archive, construct a WKWebView, and load the content using webView.loadFileURL(indexHtmlUrl, allowingReadAccessTo: parentDirectory) This works fine, but we'd also like to be notified on any rendering errors that might be raised, so we can fix them. let errorHandlerScriptString = (function() { var oldLog = console.log; console.log = function(message) { window.webkit.messageHandlers.consoleLog.postMessage(message); oldLog.apply(console, arguments); } })(); // don't even allow asking for location permissions navigator.geolocation.getCurrentPosition = function(success, error, options) { error({ PERMISSION_DENIED: 1, code: 1 }); }; window.onerror = (msg, url, line, column, error) => { const message = { message: msg, url: url, line: line, column: column, error: JSON.stri

I have an app for musicians that works with Songs and Setlists. The logical structure is as follows: A Setlist contains Songs. A Song has Sections, which include Lines (chords & lyrics). I want to view my Setlist in a Page View, similar to a book where I can swipe through pages. In this view, the Song Sections are wrapped into columns to save screen space. I use a ColumnsLayout to calculate and render the columns, and then a SplitToPages modifier to divide these columns into pages. Problem: The TabView sometimes behaves unexpectedly when a song spans multiple pages during rendering. This results in a transition that is either not smooth or stops between songs. Is there a better way to implement this behavior? Any advice would be greatly appreciated. struct TestPageView: View { struct SongWithSections: Identifiable { var id = UUID() var title: String var section: [String] } var songSetlistSample: [SongWithSections] { var songs: [SongWithSections] = [] //songs for i in 0...3 { var
