“column”

I've been trying to build an app using NavigationSplitView and SwiftUI on iOS 16. I noticed that as soon almost as the app enters the background (sometimes I have to wait a few seconds before immediately reopening the app) the contents of the NavigationSplitView are reset. This behavior differs from a NavigationStack using essentially the same path and app structure. I'm wondering if anyone has any idea why this happens? I did a little investigation and can say I've noticed a few things If using a List with a selection item specified, the selection item is set to nil when the app enters the background. For NavigationSplitView this typically will reset the downstream Detail or Content view since the value is lost If using a List without the selection parameter specified this effect is mitigated but the view still is reset and things like scroll position are wiped despite no content changing. Self._printChanges() indicates the view is unchanged despite being reset to its initial state. Using Apple's own WWDC sa

Hello, I migrated a project to use String Catalogs (Localizable.xcstrings) instead of Localized.strings and Localized.stringsdict files. So far so good, but since I use a lot localized strings in my project, there are quite some localizations used more than once in different contexts and thus with different comments. For example: Source file 1: String(localized: Something, comment: Button title for context1) Source file 2: String(localized: Something, comment: Column title for context2) This results to a Localized.xcstrings file with this content: { sourceLanguage : en, strings : { Something : { comment : Column title for context2nButton title for context1 } }, version : 1.0 } The main problem with this is, that the order of the concatenated comment changes randomly during each build. After the next Xcode build (without any code changes), the same Localized.xcstrings file might look like this: { sourceLanguage : en, strings : { Something : { comment : Button title for context1nColumn title f

I'm creating a view by reading several json files at once. I'm reading 6 files from indexes 0 to 5 and displaying each view. Until the day before yesterday, only the view of index 0 was executed and the rest of the errors appeared, but I didn't correct anything, but the file in index 1 starts to read, and from 2 the same error appears. In my json file, there is no '/' in row 1 of column 1, but there is a '/' in row 1 of column 1, so I think they say that they can't read it as a json file [ { name: recipe1, id: 1001, description: 1, imageName: Recipe01 }, { name: recipe2, id: 1002, description: 2, imageName: Recipe01 }, { name: recipe3, id: 1003, description: 3, imageName: Recipe01 }, { name: recipe4, id: 1004, description: 4, imageName: Recipe01 }, { name: recipe5, id: 1005, description: 5, imageName: Recipe01 }, { name: recipe6, id: 1006, description: 6, imageName: Recip01 }, { name: recipe7, id: 1007, description: 7, imageName: Recip01 } ]

Hi, When creating a 3 columns Split View in SwiftUI the second view that resemble the mails list in Apple Mails App have a blue icon at top left corner where when tapped shows the column of Mail boxes such as Inbox, Sent etc. This icon by default when creating the Split View disappears after tapping, it shows the third column and disappear , I would like it to stay so I can show and collapse the first column sam as Apple Mail App. how to do that ? its called back also how to rename it and add icon to it ?

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?

I have created a simple calendar framework of my own. The screenshot below shows what it looks like. The following lines show a concise version of my calendar framework. The deal is such that the app will return a date when I tap a date button with the callBack closure. import SwiftUI struct ContentView: View { @State private var navigateToAddDate = false @State private var days: [Day] = [] @State var callBack: ((Date) -> Void) private let cols = [ GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible()) ] var body: some View { NavigationStack { VStack { LazyVGrid(columns: cols) { ForEach(days, id: .self) { day in Button(action: { selectedDay = day navigateToAddDate.toggle() }, label: { Image(systemName: (day.num).circle.fill) .resizable() .aspectRatio(contentMode: .fit) .foregroundColor(day.show ? dateTextForecolor(day: day) : .clear) }) .disabled(day.isInvalid) } } } } } } struct ContentView_Pr

I'm using a two column NavigationSplitView, where the view passed for the detail column is the root of a NavigationStack. The navigation works as expected, but the navigationTitle and toolbar elements of the detail view are very slightly delayed when the view appears on iOS, such that they 'pop' in rather than smoothly animating like normal. Returning to the root of the view from views higher in this stack animates as expected. Has anyone seen anything like this before? Thanks!

How does one declare a TableColumn with a nullable field? I have a Book model with several nullable fields: struct Book: Codable, Equatable, Identifiable { // ... let productURL: String? // ... } This is how I'm trying define the corresponding TableColumn: TableColumn(Product URL, value: .productURL) { book in Text(String(book.productURL ?? )) } Though this results in several errors: Referencing initializer 'init(_:value:comparator:content:)' on 'TableColumn' requires that 'Book' inherit from 'NSObject' Referencing initializer 'init(_:value:comparator:content:)' on 'TableColumn' requires that 'Book' inherit from 'NSObject' Referencing initializer 'init(_:value:comparator:content:)' on 'TableColumn' requires the types 'KeyPathComparator' and 'SortDescriptor' be equivalent Referencing initializer 'init(_:value:comparator:content:)' on 'TableColumn' requires the types 'KeyPathComparator' and 'SortDescriptor' be equivalent Other, non-nullable columns work just fine. For example: TableColumn(ID, value: .i
