column

I'm building a Swift app, and can successfully populate the rows of an NSTableView using Cocoa bindings in a Storyboard. When I hook up a NSTableColumn's Sort Key & Selector, the click-on-column-heading becomes active (the sort-direction icons appear as expected), but the rows are not re-sorted. I've thrashed around a bit, replacing my Swift Array with an NSMutableArray, trying variations on Sort Key, but no joy... Anyone have any clues?

In iTunes the Songs view allows a Column Browser, which is essential to navigate large libraries.I hope its lack is just temporary. With thousands of albums scrolling through pretty pictures or an endless song list is not practical.

In documentation and online discussions, everyone refers to a Download Size column in the popup that appears when, in iTunes Connect, we click on Activity > [build number] > App Store File Sizes (under Compressed File Size). However, I only have the Installation Size column in my version.Has anyone else experienced this? Does anyone know why?Thanks.

How to use double/triple columns navigation style in SwiftUI document-based app? The problem is that the DocumentGroup() itself, seems already a NavigationView. In a non-document-based app, we can simply achieve this using three views within a navigation view. However, this is not the case for DocumentGroup. The views will be VStack-ed. I've also tried setting the navigation view style as double column, which also failed. Any workaround? @main struct SomeApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { var body: some View { NavigationView { LeftPanelView() MidPanelView() RightPanelView() } } }

I'm building up a data frame for the sole purpose of using that lovely textual grid output. I'm getting output without any issue, but I'm trying to sort out how I might apply a formatter to a specific column so that print(dataframeInstance) just works nicely. In my use case, I'm running a function, collecting its output - appending that into a frame, and then using TabularData to get a nice output in a unit test, so I can see the patterns within the output. I found https://developer.apple.com/documentation/tabulardata/column/description(options:), but wasn't able to find any way to pre-bind that to a dataframe Column when I was creating it. (I have some double values that get a bit excessive in length due to the joys of floating point rounding) Is there a way of setting a formatter on a column at creation time, or after (using a property) that could basically use the same pattern as that description method above?

Since macOS 10.13 we can use NSTableView with automatic row heights, thanks to the new property usesAutomaticRowHeights and of course auto layout. This works quite nicely.But when the user resizes a column, the calculated heights are no longer correct, and gaps appear in the tableview cells.Is there a proven way to update the row heights after column resize in this scenario?I already tried methods like updateConstraintsForSubtreeIfNeeded(), updateConstraints(), setNeedsDisplay(), reloadData() and so on, but nothing works.

I'm building a SwiftUI app for iPad using a NavigationSplitView as the navigation root. Below is a simplified version of the app's navigation. There are a Home Page and a Settings Page, each with its own NavigationStack. The page that appears in the detail column depends on the sidebar's selection value. The issue I'm facing is that when I navigate deeply into the Home Page's NavigationStack (e.g., to a Home Page Child view), switch to the Settings Page, and then switch back to the Home Page, the Home Page's navigation path has been reset to [] and the previous state is lost. The same issue occurs if I navigate deeply into the Settings Page (e.g., to a Settings Page Child view), switch to the Home Page, and then return to the Settings Page: the navigation state for the Settings Page is lost, and it reverts to the root of the NavigationStack. Why is this happening and how can I fix it so that switching pages in the sidebar doesn't reset the NavigationStack of each individual page in the detail column

Hi I am building a simple multi column CollectionView here and trying to add 3 cell in a row. Well, in short the column and rows looks all fine if I comment the below code. which is no image and text assigned to cells. let framework = list[indexPath.item] cell.configure(framework) However, once uncommented, only a single cell is displayed per row and the image doesn't seem to be resizing automatically. Can you please advise. Below is the ViewController. import UIKit class FrameworkListViewController: UIViewController { @IBOutlet weak var collectionView: UICollectionView! let list: [AppleFramework] = AppleFramework.list override func viewDidLoad() { super.viewDidLoad() collectionView.dataSource = self collectionView.delegate = self } } extension FrameworkListViewController: UICollectionViewDataSource { func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return list.count } func collectionView(_ collectionView: UICollectionView, cellForItemA

Is it possible to have conditional table columns for a swifui Table statement? Like for this code TableColumn(Image) { artPiece in if let imageData = artPiece.artImage.first, let image = UIImage(data: imageData!) { Image(uiImage: image) .resizable() .frame(width: 50, height: 50) } else { Image(systemName: photo) .resizable() .frame(width: 50, height: 50) } } .customizationID(Image) TableColumn(Name, value: .artName) .customizationID(Name) TableColumn (Art ID, value: .artPieceID) { artPiece in Text(String(artPiece.artPieceID)) } .customizationID(Art ID) have a conditional TableColumn for this part of my SWIFTDATA model var artDefinedFields: [ArtDefinedFields] = [] or if I change the variable string array to this var artDefinedFields: [ArtDefinedFields] = Array(repeating: ArtDefinedFields(), count: 10), initialize the array with None and only create a TableColumn when there is aArtDeginedFields value other than None

Hello, I configured a SplitViewController in Storyboard. Master and detail controller are each connected to a separate NavigationController that each has a separate TableViewController as root view controller. The master view controller is connected to the detail view controller to show detail in the segue. In code i set preferredDisplayMode = .allVisible to always show master and detail view controller side-by-side in regular size class. That worked well in iOS 13. Now, using latest iOS 14 beta the initial view shows the detail view controller instead of master even in regular size class only one view controller is shown at the same time. In Storyboard Two Columns is selected and i set One Column Beside as Display Mode and Tile as Behavior. Unfortunately that didn't help to restore the behavior as in iOS 13.
