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() } } }

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.

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

I am currently working on a MacOS project (Swift 4, Xcode 9) to shows different sets of data in one NSTableView, users can add, delete, and move around their created data sets, and everything is bound to core data through two array controllers via the NSTableView's bindings inspector sections (one to many between the column data entity and title/presets entity)Unfortunately, the Header Title binding seems to be in the Column -> Binding inspector -> Parameter section, and is read only (based on Apple documentation).https://developer.apple.com/library/content/documentation/Cocoa/Reference/CocoaBindingsRef/BindingsText/NSTableColumn.html#//apple_ref/doc/uid/NSTableColumn-SW48As I've also implemented a custom TableHeaderCell class that allows the editing of the column's Header titles (field editor call in the NSTableView double click method), even if the cell is updated via the custom class, the header title binding will not update the array controller or core data.Custom NSTableH

https://developer.apple.com/documentation/apple_news/collection_display#see-alsoHi, I have a container using the following with a nested image and text component that both take 50% of the width of the container which is great for mobile, but for tablet, I'd like to be able to specify the maxwidth of only the image so that it takes 30% or a column span of 3 for larger displays. Does anyone know how to achieve that type of layout?contentDisplay: { type: collection, gutter: 15, rowSpacing: 30, distribution: wide, variableSizing: true }thanks!

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
