column

I must have been imprecise, my problems are: I don’t know how to read the two different columns per row of a csv into two seperate lists I want to have one vstack containing a scrollable list of all the company names in the corresponding color. E.g. with the csv file: Apple,#FFFFFF Adobe,#FF0000 I want a white text element reading “Apple” and a red text with “Adobe underneath

How do I now separate the two columns from each other You could use a HStack . how do I implement this in a ForEach struct If I understand correctly, I would create 2 computed var to hold each of the columns content. And use these var in 2 ForEach in the HStack

NavigationView was deprecated but was replaced by two new views: NavigationStack (single column) and NavigationSplitView (multiple columns). In your case, you should just use a NavigationStack where you would have otherwise used a NavigationView.

Does your app use column-style layouts(for iOS 14 and later) of UISplitViewController or a classic interface style? I guess the classic interface style might be the problem.

There seems no way to work with NavigationSplitView other than List at first column for now, but I think adding a empty List with selection parameter can solve this problem almostly. Here's my solution: var categories : [Category] // can be replaced to NavigationPath @State var path : Category? = nil @State var subpath : Item? = nil var row = [ GridItem(), GridItem(), GridItem() ] var body: some View { NavigationSplitView { LazyVGrid(columns: row) { ForEach(categories) { category in Button(category.title) { path = category } // can use NavigationLink with value parameter, .onTapGesture, etc. } } // coordinates with the NavigationSplitView via selection parameter. List(selection: $path) {} } content: { // MiddleSidebarView(category: path, selection: $subpath) } detail: { // ... } } You can resize or hide List, but always have to be active while navigation feature is needed.

@OOPer, thx for sharing your code. @JL, in a one-to-one port of Apple‘s ray tracer sample (Accelerating ray tracing using Metal) one would use the transpose of the matrix because the sample uses row-first order and MTLAccelerationStructureInstanceDescriptor.transformationMatrix expects column-first. anInstanceDescriptorPointer.pointee.transformationMatrix = MTLPackedFloat4x3(aNodeInstance.transform.transpose) Without transpose the render result seems to be a single Cornell Box but in fact are nine instances stacked at the same position. A bit late, but in case anyone else will come across…

This is the default behaviour for NavigationView – single column in a compact horizontal size class and a two/three column layout in a regular size class. Either apply this modifier to the NavigationView: navigationViewStyle(.stack) or use a NavigationStack instead.

I figure out the issue but still unable to fix it. Firstly, I made it stop working with me by replicating all the steps the user do. Once the data is read from the SQLite table from a field type string (text typed in SQLite) using sql_column_text() function the result itself contains literal text of Optionaland will break everything. real code when I am attempting to fix, reading user department: let stringValue = String(cString: sqlite3_column_text(Statement, index)) // attempt This will show in the debugger as Optional(Dev team) and the UI where the user changes the information, also shows exactly that way! All of this trouble after updating to XCode 5 (original was done with version 4). I opened the database using a 3rd party software and these characters are there! Here how I read the data: struct ColumnValue { var Column: String var Value: Any? // Need to be any because will support int, float, string at least.. using Any or Any makes no difference } var ResultSet: [ColumnValue] var columnValue:

Hi, yes you can access this data through the Instruments trace that Xcode records when it creates a Core ML Performance Report. Steps: Click on Open in Instruments in the top right corner Click on the Core ML track on the left side In the Model Activity Aggregation view below, expand * All * You should see a column that gives you the average for stats like Load/Compile/Prediction etc Hope that helps, please let us know if you encounter any issues with this. Thanks.
