I've been trying to disable the "Smart Selection" feature introduced in https://developer.apple.com/wwdc20/10107 from a PKCanvasView. This feature could be very useful for some apps but if you want to start from a clean state canvas it might get in your way as you add gestures and interactions. Is there any way to opt out from it? The #WWDC20-10107 video demonstrates the "Smart Selection" feature at around 1:27.

I'm reworking my app and update code and design. Because my app is one both iPhone and iPad, i'm using Splitview to handle the configurations. But my app has 4 section that I manage using a Tab bar and each tab has a SplitView. As you can see in images, the problem is that if I attach directly the UISplitViewController to UITabBarController you don't see two columns but only one (the primary or secondary view) both iPhone landscape orientation and iPad. A solution that I found is to attach the splitviewcontroller to a view that contains a ContainerViewController e connect the split view to this container. If you do this, you see the split view work correctly ma the problem is the customization of appearance (look at image 3) So may questions are: why I have to embed a split view in a container view controller and i can't connect it directly to tabbar as we done until now? Is there an other better solution then put a split view in a containerView? Thank you )

Hi All, I'm very new to iOS development and Swift UI is my first coding language. I'm trying to link the users search results in Spotlight with the detail view that is stored in Core Data. I can search for users data in spotlight but when I tap on it, it's only appearing in the main view of the app. Is there anyways that I can use .onContinueUserActivity at the launch of the app or is there any different code that I have to use? I've searched for many articles but I couldn't get a solution. It would be good if anyone can share some links or guide here. Thank you. .onContinueUserActivity(DetailView.productUserActivityType) { userActivity in             if let product = try? userActivity.typedPayload(Product.self) {                 selectedProduct = product.id.uuidString             }         } I get this code from Apple's State restoration app but I can't use this with Core Data.

In a SwiftUI lab, I was asking about setting the focus state down a view hierarchy. The answer I got was to pass the focus state down the views as a binding. Conceptually, that made sense, so I moved on to other questions. But now that I am trying to implement it, I am having problems. In the parent view, I have something like this: @FocusState private var focusElement: UUID? Then I am setting a property like this in the child view: @Binding var focusedId: UUID? When I try to create the detail view, I'm trying this: DetailView(focusedId: $focusElement) But this doesn't work. The error I get is: Cannot convert value of type 'FocusState<UUID?>.Binding' to expected argument type 'Binding<UUID?>' What is the right way to pass down the focus state to a child view so that it can update back up to the parent view? I am trying to update from one child view, and have a TextField in a sibling view get focus.

I have an iOS 13 app that I’m hoping to release soon that is written entirely in SwiftUI. If I was starting from scratch today, I’d obviously use the new multi platform template which looks awesome.... But since I’m not starting from scratch, what are the recommendations/best practices for existing apps? Is there a path for migrating existing apps to take advantage of the new app structure (below) when moving to iOS 14? @main struct HelloWorld: App { var body: some Scene { WindowGroup { Text(“Hello, world!”).padding() } } }
