Is anyone else seeing issues with ARkit Body Tracking and SwiftUI?I am finding the the face tracking works fine if you have a view that appears with ARKit, does the tracking then goes away. This can consistently be done over and over by switching to the view and using it.But I can't do the same with BodyTracking. If I have a view that is making use of BodyTracking then it only works if I show ONLY the view with the body tracking as the very first thing to appear when running the app. If I show any other views before switching to the one with the BodyTracking then it does not work. Also if I display that first view (which works fine) the switch to another view and back to the BodyTracking view then it no longer works.This feels like a bug in ARKit, SwiftUI or iPadOS (don't have a phone to try it out).Anyone else running into problems with SwiftUI and BodyTracking?I get the following output when running my App (both when it works and when it doesn't). Feels to me like SwiftUI

Hi,create macOS project and I try to make UIViewRepresentable but get this error.import SwiftUI struct WebView: UIViewRepresentable { //Error: Use of undeclared type 'UIViewRepresentable' }What can I do with it or how can I make my own UIViewRepresentable for macOS to use WKWebView in my project?struct WebView: UIViewRepresentable { func makeUIView(context: Context) -> WKWebView { WKWebView() } func updateUIView(_ uiView: WKWebView, context: Context) { } }My question on stackoverflow

I am attempting to go through the SwiftUI tutorials on the Apple developer website - building the Landmarks app. With each starting point they provide a project file. When I open the project in XCode, everything works fine. However, when I add a new SwiftUI View to the project the preview (canvas) fails to load the default Hello World view. It states Failed to build Test.swift. Restarting XCode and/or rebooting the machine does not resolve the issue.When I add a SwiftUI View to a project that I originally created on my Mac, the preview works fine. Is there an issue with the starting point project files provided in the tutorials?This issue is preventing me from being able to do the tutorials, so any advice would be greatly appreciated!

I can't seem to figure out how to get a one-to-many relationship working with a NSPersistentCloudKitContainer. Has anyone been able to do this successfully? I see the relationship that is one-to-one on the other end, but not the relationship which is supposed to be many to many.I've been trying to use the information here https://developer.apple.com/documentation/coredata/mirroring_a_core_data_store_with_cloudkit/creating_a_core_data_model_for_cloudkit#3191035and am unsure if this is a limitation of CloudKit and CoreData, if the data is there and just not showing in the dashboard or any other option.I've put my code here on Github https://github.com/jknlsn/testcloudkit and would love any help or thoughts. I would also be very keen to hear of any better ways to be debugging and visualising this data I am trying to write apart from the CloudKit dashboard, I don't know yet how to retrieve and display the data with SwiftUI.

Hello!I'm having a hard time finding a workaround for this SwiftUI bug. At least I think it is a bug as I cannot find anything related to it anywhere.So I have the following code in a View:ForEach((1...5), id: .self) { index in HStack(spacing: 24) { Image(tallImage1200x1800) .resizable() .aspectRatio(contentMode: .fill) .frame(width: 150, height: 120) .clipped() Text(Random text) } .frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .leading) .background(Color.white) .clipShape(RoundedRectangle(cornerRadius: 15)) .shadow(color: Color.black.opacity(Double(0.3)), radius: 1, x: 1, y: 1) .padding(.vertical, 6) .padding(.horizontal, 16) .frame(height: 120) .onTapGesture { print((index)) } }The problem is that if you now tap on the lower part of any of the HStacks you will actually get the index of the next card printed out. This clearly happens because the tappable area is expanded to the new top and bottom bounds of the resized image.As a workaround I tried:- adding an

How do I create a Apple Sign In login button in watchOS 6 using SwiftUI. The documentation is not that clear about that, and I didn't understand how to extend WKInterfaceObjectRepresentable in order to do it.

Hi, I'm trying to build an app with a card-based interface, where each step down the navigation hierarchy presents a new card on top of the old one. I've built something manually that works *OK*, but the way that calling a sheet works is so much smoother and feels much more native.The problem is that my app uses a Tab View, which should still be usable when these cards start tsacking up. Does anyone know a way to bring up a sheet, without obscurring the tabs, or know another technique that might work?Thanks,T.

I created an app with a TabBar and utilized AppDelegate to control it's background color using the code below. I have a custom ColorSet in Assets (headerFooter) that sets the Light and Dark mode colors for my TabBar. The app will not change the TabBar back to the correct Light Mode color when I change from Dark to Light in the simulator or on my iPhone X.I am using Catalina v10.15 beta (19A578c) and Xcode 11.2 beta. My iPhone is running iOS 13.1.2.With the phone in Dark Mode, I open the app and it opens with the correct colors. Conversely, when I start the app with the phone in Light Mode, the app opens with the correct colors. When I change from Light Mode to Dark Mode, the colors change accordingly. However whenever I change from Dark Mode to Light Mode, the TabBar remains showing the Dark Mode color.UITabBar.appearance().barTintColor = UIColor(name: headerFooter)Any ideas?Thanks,Doug

I have a SwiftUI view that is pushed on the navigation stack (using a NavigationLink).This view is a UIViewRepresentable-wrapped UIKit-based view.To receive delegate events from my UIKit-based view, there is a Coordinater class (which is instantiated in makeCoordinator()).I now want to dismiss my SwiftUI view when one of the delegate method calls indicates a certain condition.The only way I know to dismiss a NavigationLink-pushed-view is via: @Environment(.presentationMode) var presentationMode: Binding<PresentationMode>But when I invoke in the my implementation of a delegate method (i.e., inside my Coordinator): self.mySwiftUI.presentationMode.wrappedValue.dismiss()this result in a crash: Thread 1: Fatal error: Reading Environment<Binding<PresentationMode>> outside View.body.Knowing that SwiftUI is a declarative way of creating UIs, how do I ever get this dismiss() function called? Is there a way to call a function when a @State variable changes for example?

Hello,I'm using swiftUI to render my interface, the goal is to made a simple tableView. I'm using List, passing a param that is an array from an observableObject. The array isn't empty and each element is one identifiable that has an UUID. But, my application crashes when I try to show the list on the screen. The error:[TableView] Warning once only: UITableView was told to layout its visible cells and other contents without being in the view hierarchy (the table view or one of its superviews has not been added to a window). This may cause bugs by forcing views inside the table view to load and perform layout without accurate information (e.g. table view bounds, trait collection, layout margins, safe area insets, etc), and will also cause unnecessary performance overhead due to extra layout passes. Make a symbolic breakpoint at UITableViewAlertForLayoutOutsideViewHierarchy to catch this in the debugger and see what caused this to occur, so you can avoid this action altogether if possible, or defer it
