Hello! I have an iOS app where I am looking into support for visionOS. I have a whole bunch of gestures set up using UIGestureRecognizer and so far most of them work great in visionOS! But I do see something odd that I am not sure can be fixed on my end. I have a UITapGestureRecognizer which is set up with numberOfTouchesRequired = 2 which I am assuming translates in visionOS to when you tap your thumb and index finger on both hands. When I tap with both hands sometimes this tap gesture gets kicked off and other times it doesn't and it says it only received one touch when it should be two. Interestingly, I see this behavior in Apple Maps where tapping once with both hands should zoom out the map, which only works sometimes. Can anyone explain this or am I missing something?

On TikTok on Vision Pro, the home page has different minimum and maximum window heights and widths compared to the search page. Now I am able to set minimum window size for different tab views but maximum size doesn't seem to work Code: // WindowSizeModel.swift import Foundation import SwiftUI enum TabType { case home case search case profile } @Observable class WindowSizeModel { var minWidth: CGFloat = 400 var maxWidth: CGFloat = 500 var minHeight: CGFloat = 400 var maxHeight: CGFloat = 500 func setWindowSize(for tab: TabType) { switch tab { case .home: configureWindowSize(minWidth: 400, maxWidth: 500, minHeight: 400, maxHeight: 500) case .search: configureWindowSize(minWidth: 300, maxWidth: 800, minHeight: 300, maxHeight: 800) case .profile: configureWindowSize(minWidth: 800, maxWidth: 1000, minHeight: 800, maxHeight: 1000) } } private func configureWindowSize(minWidth: CGFloat, maxWidth: CGFloat, minHeight: CGFloat, maxHeight: CGFloat) { self.minWidth = minWidth self.maxWidth = maxWidth self.minHeight = minHeight self.maxHeight = maxHeight } } // tiktokForSpacialModelingApp.swift import SwiftUI @main struct tiktokForSpacialModelingApp: App { @State private var windowSizeModel: WindowSizeModel = WindowSizeModel() var body: some Scene { WindowGroup { MainView() .frame( minWidth: windowSizeModel.minWidth, maxWidth: windowSizeModel.maxWidth, minHeight: windowSizeModel.minHeight, maxHeight: windowSizeModel.maxHeight) .environment(windowSizeModel) } .windowResizability(.contentSize) } } // MainView.swift import SwiftUI import RealityKit struct MainView: View { @State private var selectedTab: TabType = TabType.home @Environment(WindowSizeModel.self) var windowSizeModel; var body: some View { @Bindable var windowSizeModel = windowSizeModel TabView(selection: $selectedTab) { Tab("Home", systemImage: "play.house", value: TabType.home) { HomeView() } Tab("Search", systemImage: "magnifyingglass", value: TabType.search) { SearchView() } Tab("Profile", systemImage: "person.crop.circle", value: TabType.profile) { ProfileView() } } .onAppear { windowSizeModel.setWindowSize(for: TabType.home) } .onChange(of: selectedTab) { oldTab, newTab in if oldTab == newTab { return } else if newTab == TabType.home { windowSizeModel.setWindowSize(for: TabType.home) } else if newTab == TabType.search { windowSizeModel.setWindowSize(for: TabType.search) } else if newTab == TabType.profile { windowSizeModel.setWindowSize(for: TabType.profile) } } } }

Is it possible to access the main camera feed in full frame using the Enterprise API? Image tracking in Vision OS only updates once per second, so I am considering using the Enterprise API to access the camera feed and implement it using our custom learning model. Please provide a response.

Just like this pic shows, how to add secondary panel out side of the main panel by using SwiftUI?

I have looked here: Reality View Documentation Found this thread: RealityView Update Closure Thread I am not able to find documentation on how the update closure works. I am loading attachments using reality view's attachment feature (really helpful). I want to remove them programmatically from another file. I found that @State variables can be used. But I am not able to modify them from out side of the ImmersiveView swift file. The second problem I faced was even if I update them inside the file. My debugging statements don't execute. So exactly when does update function run. I know it get's executed at the start (twice for some reason). It also get's executed when I add a window using: openWindow?(id: "ButtonView") I need to use the update closure because I am also not able to get the reference to RealityViewAttachment outside the RealityView struct. My Code(only shown the code necessary. there is other code): @State private var pleaseRefresh = "" @StateObject var model = HandTrackingViewModel() var body: some View { RealityView { content, attachments in if let immersiveContentEntity = try? await Entity(named: "Immersive", in: realityKitContentBundle) { content.add(immersiveContentEntity) } content.add(model.setupContentEntity()) content.add(entityDummy) print("View Loaded") } update: { content, attachments in print("Update Closure Executed") if (model.editWindowAdded) { print("WINDOW ADDED") let theattachment = attachments.entity(for: "sample")! entityDummy.addChild(theattachment) // more code here } } attachments: { Attachment(id: "sample") { Button(action: { model.canEditPos = true model.canRotate = false pleaseRefresh = "changed" }) { HStack { Image(systemName: "pencil.and.outline") .resizable() .scaledToFit() .frame(width: 32, height: 32) Text("Edit Placement") .font(.caption) } .padding(4) } .frame(width: 160, height: 60) } } How can the update method (or the code inside it) run when I want it to? I am new to swift. I apologize if my question seems naive.
