SwiftUI in visionOS has a modifier called preferredSurroundingsEffect that takes a SurroundingsEffect.
From what I can tell, there is only a single effect available: .systemDark.
ImmersiveSpace(id: "MyView") {
MyView()
.preferredSurroundingsEffect(.systemDark)
}
I'd like to create another effect to tint the color of passthrough video if possible.
Does anyone know how to create custom SurroundingsEffects?

So I have a simple view for my SwiftUI application below:
import SwiftUI
struct ContentView: View {
var body: some View {
List {
ForEach(0..<4) { index in
RowView(index: index)
.accessibilityIdentifier("row")
}
}
}
}
struct RowView: View {
let index: Int
var body: some View {
HStack {
Image(systemName: "globe")
.imageScale(.large)
.foregroundStyle(.tint)
Text("Hello, world!")
Spacer()
ButtonView(index: index)
}
.padding()
}
}
struct ButtonView: View {
let index: Int
var body: some View {
VStack {
if index != 3 {
Button(action: {}, label: {
Text("Cancel")
})
.accessibilityIdentifier("cancel_button")
}
Button(action: {}, label: {
Text("Submit")
})
.accessibilityIdentifier("submit_button")
}
}
}
My goal is to reference each cancel and submit button per row for a UI Test, which I have tried doing so here:
let rowElements = app.tables.cells.matching(identifier: "row")
for i in 0..<rowElements.count {
let cancelButton = rowElements.element(boundBy: i).buttons["cancel_button"]
let submitButton = rowElements.element(boundBy: i).buttons["submit_button"]
XCTAssertTrue(cancelButton.exists, "Cancel button does not exist in row \(i)")
XCTAssertTrue(submitButton.exists, "Submit button does not exist in row \(i)")
}
Even with the identifiers set like this my tests fail and say it cannot find the buttons labeled as they are with their specific identifiers or the rows. What is the correct way to reference elements if they are in a list or table for UI Testing? I'm specifically trying to use accessibility Identifiers to make my life easy.

Hi
I reviewed this post:
How to change navigation title color in swiftUI
This seems to work fine if the intention is to apply the title color across an application. I would like to apply a different text title color selectively depending on the View being shown. And in some instances revert back to the color depending on the light and dark themes.
Same result occurs using a viewmodifier or simply using onAppear and onDisappear with the title color is applied to all views. And if you do modify it in onDisappear, when you navigate back to another view which changes the color onAppear it has the same color as the previous view.
The only way I've found this to work is using UIViewControllerRepresentable and handling the viewWillAppear and viewWillDisappear something like this:
NavigationBarView(
viewWillAppear: { nav in
nav.navigationBar.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
},
viewWillDisappear: { nav in
nav.navigationBar.largeTitleTextAttributes = nil
}
)
Has anyone been successful in getting a different title text color to apply to different views using a modifier or onAppear and onDisappear?
Appreciate any guidance.

I'm trying to figure out how to debug this issue. I have a fairly simple program that I built using the Hello World sample code as reference. Here is my code:
import SwiftUI
@main
struct Core_USDZ_ViewerApp: App {
var body: some Scene {
// Main Menu scene
//
WindowGroup (id: "main-menu"){
CoreUsdzMenu()
}
// Scene that takes data as an input
// for volumetric viewing
//
WindowGroup (for: URL.self) { $content in
CoreUsdzVolume(url: content)
} defaultValue: {
URL(string: "https://developer.apple.com/augmented-reality/quick-look/models/pancakes/pancakes.usdz")!
}
.windowStyle(.volumetric)
.defaultSize(width: 0.2, height: 0.3, depth: 0.3, in: .meters)
// Full surround scene
/*
ImmersiveSpace {
// put our immersive view here
} */
}
}
In the simulator, this launches the main menu scene, but when installed on the Vision Pro using TestFlight it skips the main menu and goes straight to the second WindowGroup. Since the data isn't populated, it uses the defaultValue and just shows pancakes.
I'm having trouble logging and debugging this issue, as I don't have access to the hardware myself. I have to push the code to TestFlight and wait for a coworker to test it.
Does anyone have ideas of why this could be happening? Any help is appreciated. Logging and debugging tips especially. I'm used to just putting log messages in my code to debug, but maybe there are some breakpoint techniques I should be using here or something.
Oh, also, here is my CoreUsdzMenu script:
import SwiftUI
import RealityKit
import UniformTypeIdentifiers
struct CoreUsdzMenu: View {
@Environment(\.openWindow) private var openWindow
@Environment(\.dismissWindow) private var dismissWindow
@State var entity: Entity? = nil
@State var showFilePicker: Bool = false
init() {

//
if let loadedEntity = self.entity {
placeholderEntity.children.removeAll()
placeholderEntity.addChild(loadedEntity)
}
}
)*/
// A button that displays a file picker for loading a USDZ.
//
Button(
action: {
showFilePicker = true
},
label: {
Text("Load USDZ")
}
)
.padding()
}
// can import usdz and realityFile UTT types
.fileImporter(isPresented: $showFilePicker, allowedContentTypes: [.usdz, .realityFile]) { result in
// Get the URL of the USDZ picked by the user.
// Guarded for errors.
//
guard let url = try? result.get() else {
print("Unable to get URL")
return
}
NSLog("In CoreUsdzMenu")
// add new .usdz to our data list
// for later!~
// use Observables n stuff
//usdzData.addUsdz(url)

//
//self.entity = try await Entity(contentsOf: url)

I know the short answer is, no, you cannot update an older version of your app… but it got me thinking….
could you make a new version of an app that supports older iOS versions and then quickly release another version of the app that supports iOS 16+ only?
Wouldn‘t this effectively allow you to make a new version for for iOS 12 devices and still allow you to have iOS 16+ features that are needed for the current version?
one of my apps needs features found in swiftUI (iOS 16+) but I’d like to update an old version that was not on swiftUI.
I'm on my final steps 'polishing' my app before submitting to AppStore however there is something that bothers me. My Feedback section is somehow asking for the User's data in order to submit a Feedback. Do i need to include some sort of Privacy Policy for this? The app is working offline and is for educational purposes teaching users
the basics of Swift in an interactive way. ... it doesn't require any sensitive information from the user apart from this form...Feedback is critical, any suggestion?

I have a SwiftUI menu
Menu{
....
}, label : {
Image(...).accessibility(identifier: "cardMenu")
}
I used to be able to bring up the menu (before upgrading to xcode 13 (ios15)) like this
let app = XCUIApplication()
app.launch()
app.buttons["cardMenu"].tap()
But now i am unable to see the identifier in app.buttons. Can't seem to find the identifier anymore. I've tried looking for the identifier in the other app fields and changing to use text instead of identifer. No luck. These tests used to work prior to the upgrade.
Any help would be appreciated

I need to create a carousel component with the following requirements (sorted by relevance):
Objectives
Every image is 16:9 aspect ratio and resizes to fit the screen.
Needs a zoom and pan functionality, possibly the same way as iOS Photos app.
Needs to work both in landscape and portrait mode, with a smooth transition between orientations.
When orientation changes, the image needs to be rotated to preserve the center of the image (like Photos app and hyperoslo/Lightbox)
The component should only take the minimum necessary space. In most use cases, such component should have other subviews both above and below.
Circularity. I would like the carousel to wrap around.
What I tried:
Using a TabView with .tabViewStyle(PageTabViewStyle()).indexViewStyle(PageIndexViewStyle(backgroundDisplayMode: .always)) modifiers.
This didn't work: rotating the interface caused the view to get stuck between pages (it looks like it's a well known [bug]).(https://stackoverflow.com/questions/72435939/swiftui-tabview-is-not-working-properly-on-orientation-change).
Implementing a single page (that is, an image view) using an UIScrollView and an UIViewRepresentable, then collecting them into an HStack.
Unfortunately I need to use zoomScale and contentOffset properties of the UIScrollView outside of the UIViewRepresentable itself. The net result was that .init() was invoked for every image in the carousel at every rotation, causing severe stutters and an horrible rotation animation.
Implementing the whole carousel using UIKit, and an UICollectionView, whose cells were an instance of UIScrollView.
The problem is, the UIScrollView needs to recompute its constraints upon rotation but a cell is an instance of UIView, so it can't respond to rotations via viewWillTransition(to:CGSize, with: any UIViewControllerTransitionCoordinator).
In the UICollectionView itself, you can only access the visible cells (one at a time is visible), and cells are cached, so even after rotating, some occasionally are presented on screen with the same appearance as before the rotation (some do, some don't, in the same UICollectionView). Also when rotating, it looks like the UIScrollView of the visible cell is being recreated, making it impossible to preserve the image center (I use this subclass of UIScrollView for this purpose). And the UICollectionView is taking the full window size, not just the bare minimum necessary space.
Help:
With all of this in mind, what options do I realistically have? If necessary I can raise the minimum iOS version to 16.0, even though I guess it doesn't make any significative difference since SwiftUI introduced MagnifyGesture only from iOS 17.0.

I was coding a sidebar on macOS and folded it with my mouse, but every time I run the app, I can't see the sidebar, so I can't use the sidebar.
If you add a new image once, you can't see the same, but the third window also shows the sidebar well. I don't know why
It's similar when you run it on another computer at all.
Current code
import CoreData
struct ContentView: View {
@Environment(\.managedObjectContext) private var viewContext
@State private var isSidebarVisible: Bool = true
var body: some View {
NavigationView {
if isSidebarVisible {
Sidebar()
}
MemoListView().environment(\.managedObjectContext, viewContext)
}
.frame(minWidth: 700, minHeight: 400)
.toolbar {
ToolbarItem(placement: .navigation) {
Button(action: toggleSidebar) {
Image(systemName: "sidebar.leading")
}
}
}
}
private func toggleSidebar() {
withAnimation {
isSidebarVisible.toggle()
}
}
struct Sidebar: View {
@Environment(\.managedObjectContext) private var viewContext
var body: some View {
List {
NavigationLink(destination: EasyWebListView().environment(\.managedObjectContext, viewContext)) {
Label("Web Links", systemImage: "link")
}
NavigationLink(destination: MemoListView().environment(\.managedObjectContext, viewContext)) {
Label("Memos", systemImage: "note.text")
}
NavigationLink(destination: ThemeListView().environment(\.managedObjectContext, viewContext)) {
Label("Themes", systemImage: "photo.on.rectangle.angled")
}
NavigationLink(destination: AccessView().environment(\.managedObjectContext, viewContext)) {
Label("Access Records", systemImage: "clock.fill")
}
}
.navigationTitle("My App")
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView().environment(\.managedObjectContext, PersistenceController.preview.container.viewContext)
}
}
And the code used when there was a problem before.

Hi Folks,
I would like it so that when I press the button on the HomeScreen, the TabView hides and the toolbar item appears in its place.
Currently, the toolbar item stacks on top of the TabView. However, when I try to hide the TabView, with an if condition for example, the screens turn black. I think it's because of the screen calls in the TabView. Is there an option to achieve what I want?
I'm new to SwiftUI, so I'm very glad for any Solutions or advices.
struct NavBar: View {
var body: some View {
TabView {
HomeScreen()
.tabItem {
Label(
"Home",
systemImage: "house"
)
}
...
}
}
}
struct HomeScreen: View {
@State private var showDeleteButton = false
var body: some View {
Button("Show/Dissmiss Delete Button", action: {
showDeleteButton.toggle()
}).toolbar {
if showDeleteButton {
ToolbarItem(placement: .bottomBar) {
Button("Delete", action: {})
}
}

I have a simple main app architecture:
struct ContentView: View {
@State private var isSignedIn = false
@AppStorage("onboardingCompleted") var onboardingCompleted: Bool = false
var body: some View {
Group {
if onboardingCompleted && isSignedIn {
MainView()
} else {
OnboardingView()
}
}
.onAppear() {
signIn()
}
}
OnboardingView is a NavigationView. MainView is a TabView. I switch between these when the user finishes onboarding. However, as the user taps on the finish button in the last onboarding step, this gets written to the console:
Trying to pop to a missing destination - SwiftUI/NavigationBridge_PhoneTV.swift:213 - please file a bug report.
In production, this causes a crash. I looked around and it seems it is an issue when you embed TabView inside NavigationView or vice versa? But here it's not the case, they are standalone and I switch between them.
Any thoughts?

I want to have a list of tasks and each task have a list of navigationLinks each NavigationLink has subtaskName as a label and subtaskDetails as destination and every List (tasks list and subtasks list) has .onDelete and .onMove behaviors
But when I implement the code below the navigationLink act weird. navigationLink inside List inside List is not navigating when clicked and it is only triggered and navigates to SubtaskDetailView when clicking the outer List row. How can I fix this problem?
import SwiftUI
struct ContentView: View {

}
.onDelete(perform: deleteTask)
.onMove(perform: moveTask)
}

.toolbar {
EditButton()
}
}
}
private func deleteTask(at offsets: IndexSet) {
tasks.remove(atOffsets: offsets)
}
private func moveTask(from source: IndexSet, to destination: Int) {
tasks.move(fromOffsets: source, toOffset: destination)
}
}
struct TaskView: View {
@Binding var task: Task
var body: some View {
List {
Text(task.name)
.font(.headline)
.padding(.bottom, 4)
ForEach(task.subtasks.indices, id: \.self) { index in
NavigationLink(destination: SubtaskDetailView(details: task.subtasks[index].details)) {

}
}
.onDelete(perform: { indexSet in
task.subtasks.remove(atOffsets: indexSet)
})
.onMove(perform: { indices, newOffset in
task.subtasks.move(fromOffsets: indices, toOffset: newOffset)
})
}
.frame(minHeight: CGFloat(task.subtasks.count) * 80)

Hello! I've been trying to create a custom USDZ viewer using the Vision Pro. Basically, I want to be able to load in a file and have a custom control system I can use to transform, playback animations, etc.
I'm getting stuck right at the starting line however. As far as I can tell, the only way to access the file system through SwiftUI is to use the DocumentGroup struct to bring up the view. This requires implementing a file type through the FileDocument protocol.
All of the resources I'm finding use text files as their example, so I'm unsure of how to implement USDZ files. Here is the FileDocument I've built so far:
import SwiftUI
import UniformTypeIdentifiers
import RealityKit
struct CoreUsdzFile: FileDocument {
// we only support .usdz files
static var readableContentTypes = [UTType.usdz]
// make empty by default
var content: ModelEntity = .init()
// initializer to create new, empty usdz files
init(initialContent: ModelEntity = .init()){
content = initialContent
}
// import or read file
init(configuration: ReadConfiguration) throws {
if let data = configuration.file.regularFileContents {
// convert file content to ModelEntity?
content = ModelEntity.init(mesh: data)
} else {
throw CocoaError(.fileReadCorruptFile)
}
}
// save file wrapper
func fileWrapper(configuration: WriteConfiguration) throws -> FileWrapper {
let data = Data(content)
return FileWrapper(regularFileWithContents: data)
}
}
My errors are on conversion of the file data into a ModelEntity and the reverse. I'm not sure if ModelEntity is the correct typing here, but as far as I can tell .usdz files are imported as ModelEntities.
Any help is much appreciated!

My app is iOS 17 targeted and uses a card-based list view with Delete and Duplicate trailing and leading swipe actions. The Delete and Duplicate buttons display appropriately on iPad with rounded corners, height equal to card height and width expanding to fill the leading or trailing space created by the swipe action (with padding between the edge of the button and the edge of the card). See screenshot:
However, on iPhone (a) the button heights extend from the top of the first card to the bottom of the last card in the scrolled list, (b) the width expands to completely fill the space without padding between the button and the cards, and (c) only the leading (or trailing) top and bottom corners are rounded (respectively). See screenshots:
The swipe action modifiers are standard and applied on a CardView in the following view chain (NavigationSplitView -> ZStack -> Group -> ZStack -> List -> ForEach -> ZStack -> CardView | NavigationLink with empty view as workaround for a toolbar bug.
Here are the swipe actions :
.swipeActions(edge: .trailing, allowsFullSwipe: false) {
Button(role: .destructive, action: {
// Perform "Delete" action
}) {
Label("Delete", systemImage: "trash")
}
}
.swipeActions(edge: .leading, allowsFullSwipe: false) {
Button(action: {
// Perform "Duplicate" action
}) {
Label("Duplicate", systemImage: "doc.on.doc")
}
}
I’ve tried embedding the buttons within a Geometry reader to explicitly contain the height and width but this results in a compiler error and I suspect that the solution might be a lot simpler. Any thoughts on a fix or an explanation of why the buttons display properly on iPad device and simulator but not on iPhone device or simulator is appreciated. Thanks in advance!

Some users report random crashing when just navigating the app. The app is really simple, here is the structure (it's MVP so most of the screens are not done yet):
@State private var isChatModalPresented = false
@State private var selectedTab = 0
@State private var previousTab = 0
var body: some View {
TabView(selection: $selectedTab) {
Text("Dashboard")
.tabItem {
Label("Dashboard", systemImage: "house")
}
.tag(0)
Text("Training")
.tabItem {
Label("Training", systemImage: "flame")
}
.tag(1)
Text("")
.tabItem {
Label("Chat", systemImage: "bubble.left")
}
.tag(2)
Text("Recovery")
.tabItem {
Label("Recovery", systemImage: "heart")
}
.tag(3)
Text("Community")
.tabItem {
Label("Community", systemImage: "person.3")
}
.tag(4)
}
.onChange(of: selectedTab) { neco in
if selectedTab == 2 {
self.isChatModalPresented = true
selectedTab = previousTab
} else {
previousTab = selectedTab
}
}
.fullScreenCover(isPresented: $isChatModalPresented) {
ChatView(isPresented: $isChatModalPresented)
}
}
}
It's supposed to be a standard tabview, except that when you tap on the middle item, it's supposed to present a view from the bottom using fullScreenCover. Is this code correct?

After updating our build server to Xcode 15.3, the frameworks (e.g. CCIeNewsNetworking) we build and release seems to reference SwiftUI.
Our deployment target is iOS11.
Customers have complained when running on iOS12:
dyld: Library not loaded: /System/Library/Frameworks/SwiftUI.framework/SwiftUI
Referenced from: /private/var/containers/Bundle/Application/81538A25-464A-46E0-BC4D-6E1C002C82F0/Test.app/Frameworks/CCIeNewsNetworking.framework/CCIeNewsNetworking
Reason: image not found
and I can see that "import SwiftUI" now appears in arm64-apple-ios.private.swiftinterface:

I don't recall having changed anything in the project settings, so where does "import SwiftUI" come from, and how can I avoid it ?
Post not yet marked as solved
as the title said, I want to sample the current pixel in the layer and if the color is the same as one in the parameter, I need to find a way to return that position back to SwiftUI.
Do you think that's possible?
in Shader.Argument I didn't find a way to directly convert to a pointer.
I have encountered an issue with nested view updates that I don't understand. Maybe someone can explain what is happening.
In the code below the ContentView loads 2 views in succession. MyView1 followed by MyView2. MyView displays a button while MyView2 displays the value of its first argument. When the button is pressed MyView1 changes the value of its bound first argument. The ContentView is reloaded because of the change to its first argument. This results in MyView1 and MyView2 both being loaded again. Looked at from a procedural point of view this isn't what I was expecting.
import SwiftUI
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
struct ContentView: View {
@State var mydata1:Int = 0
@State var mydata2:Int = 1
var body: some View {
VStack {
Text("Hello world \(mydata1)")
MyView1(v1:$mydata1, v2:$mydata2)
Text(" myData1 = \(mydata1) myData2 = \(mydata2) ")
MyView2(v1:$mydata1, v2:$mydata2)
Text("Bye bye \(mydata1)")
}
}
}
struct MyView1:View {
@Binding var v1:Int
@Binding var v2:Int
var body: some View {
Text("MyView1")
if $v1.wrappedValue == 0 {
Button(action: {
$v1.wrappedValue = 10
}, label: {
Text("OK")
})
}
}
}
struct MyView2:View {
@Binding var v1:Int
@Binding var v2:Int
var body: some View {
Text("MyView2")
if $v1.wrappedValue == 0 {
Text("v1 = \(v1) v2 = \(v2) ")
}
else {
Text("???")
}
}
}
