Thanks, that’s really useful. I’m surprised that UICollectionView has a lot of UITableView features and more.

Yes. The table view will load with the desired style when the view is presented but if the user rotates the device the style doesn't change.

If you mean having only one view showing at a time, like on iPhone (not master-detail), then you can use StackNavigationViewStyle(). A navigation view style represented by a view stack that only shows a single top view at a time. Use it like this as a modifier on the NavigationView: NavigationView { ... } .navigationViewStyle(StackNavigationViewStyle())

ProgressView() was introduced to iOS14 but I don’t think that calling you’re own view struct that name is the problem. Try unchecking the Enable Results settings next to the run button. I find that this causes the problem with slow rendering and the Abort called messages, as it does say that it May reduce performance.

I have found that on iPad turning off Enable Results will result in little to no aborts called and the code will run quicker. With the setting on, even if your code is correct (without mistakes or bugs), the complier throws errors and aborts are called.

I believe using this results in the correct alignment. extension HorizontalAlignment { private struct CenterLine: AlignmentID { static func defaultValue(in context: ViewDimensions) -> CGFloat { context[HorizontalAlignment.center] } } static let centerLine = Self(CenterLine.self) } Needing to add this to the container VStack(alignment: .centerLine) { ... } and this to the views in the HStacks .alignmentGuide(.centerLine) { $0[.trailing] } // for text label on left .alignmentGuide(.centerLine) { $0[.leading] } // for control on right
