Is it just me or does running SwiftUI apps using Xcode 16 give so many warnings and errors in the console that it's impossible to debug everything? Even the simplest gestures such as a long press generate a warning. I'm starting to ignore them, which feels negligent. Any insights/tips?

Following up on my previous question here: https://developer.apple.com/forums/thread/774262
Having solved the clipping problem, I am now trying to overlay some content in front of the RealityView. However, it looks like any content with transparency does not render in front of the RealityView, while opaque views seem to work; placing content with transparency like glassBackgroundEffect() behind the RealityView in a ZStack causes the entire window to flicker.
Additionally, my SwiftUI attachment placed in front of the stereoscopic image plane are invisible if the user look at it straight at 90 degrees. However, if the user look at it from increasing angles from the sides, the attachment gradually turns visible again.
Are these behaviors expected? What is a recommended approach to overlay content in front of a RealityView? Thanks!
I've been running into an issue using .fileImporter in SwiftUI already for a year. On iPhone simulator, Mac Catalyst and real iPad it works as expected, but when it comes to the test on a real iPhone, the picker just won't let you select files. It's not the permission issue, the sheet won't close at all and the callback isn't called. At the same time, if you use UIKits DocumentPickerViewController, everything starts working as expected, on Mac Catalyst/Simulator/iPad as well as on a real iPhone.
Steps to reproduce:
Create a new Xcode project using SwiftUI.
Paste following code:
import SwiftUI
struct ContentView: View {
@State var sShowing = false
@State var uShowing = false
@State var showAlert = false
@State var alertText = ""
var body: some View {
VStack {
VStack {
Button("Test SWIFTUI") {
sShowing = true
}
}
.fileImporter(isPresented: $sShowing, allowedContentTypes: [.item]) {result in
alertText = String(describing: result)
showAlert = true
}
VStack {
Button("Test UIKIT") {
uShowing = true
}
}
.sheet(isPresented: $uShowing) {
DocumentPicker(contentTypes: [.item]) {url in
alertText = String(describing: url)
showAlert = true
}
}
.padding(.top, 50)
}
.padding()
.alert(isPresented: $showAlert) {
Alert(title: Text("Result"), message: Text(alertText))
}
}
}
DocumentPicker.swift:
import SwiftUI
import UniformTypeIdentifiers
struct DocumentPicker: UIViewControllerRepresentable {
let contentTypes: [UTType]
let onPicked: (URL) -> Void
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
func makeUIViewController(context: Context) -> UIDocumentPickerViewController {
let documentPicker = UIDocumentPickerViewController(forOpeningContentTypes: contentTypes, asCopy: true)
documentPicker.delegate = context.coordinator
documentPicker.modalPresentationStyle = .formSheet
return documentPicker
}
func updateUIViewController(_ uiViewController: UIDocumentPickerViewController, context: Context) {}
class Coordinator: NSObject, UIDocumentPickerDelegate {
var parent: DocumentPicker
init(_ parent: DocumentPicker) {
self.parent = parent
}
func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
print("Success!", urls)
guard let url = urls.first else { return }
parent.onPicked(url)
}
func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {
print("Picker was cancelled")
}
}
}
Run the project on Mac Catalyst to confirm it working.
Try it out on a real iPhone.

We use @Query macro in our App. After we got macOS 15.3 update, our App crashes at @Query line.
SwiftData/Schema.swift:305: Fatal error: KeyPath \Item.<computed 0x0000000100599e54 (Vec3D)>.x points to a field (<computed 0x0000000100599e54 (Vec3D)>) that is unknown to Item and cannot be used.
This problem occurs only when the build configuration is "Release", and only when I use @Query macro with sort: parameter. The App still works fine on macOS 14.7.3.
This issue seems similar to what has already been reported in the forum. It looks like a regression on iOS 18.3.

Hi folks,
Unsure if I've implemented some sort of anti-pattern here, but any help or feedback would be great.
I've created a minimal reproducible sample below that lets you filter a list of people and mark individuals as a favourite.
When invoking the search function on a physical device running iOS 18.3.1, it crashes with Swift/ContiguousArrayBuffer.swift:675: Fatal error: Index out of range.
It runs fine on iOS 17 (physical device) and also on the various simulators I've tried (iOS 18.0, iOS 18.2, iOS 18.3.1).
If I remove the toggle binding, the crash doesn't occur (but I also can't update the toggles in the view model).
I'm expecting to be able to filter the list without a crash occurring and retain the ability to have the toggle switches update the view model.
Sample code is below. Thanks for your time 🙏!
import SwiftUI
struct Person {
let name: String
var isFavorite = false
}
@MainActor
class ViewModel: ObservableObject {
private let originalPeople: [Person] = [
.init(name: "Holly"),
.init(name: "Josh"),
.init(name: "Rhonda"),
.init(name: "Ted")
]
@Published var filteredPeople: [Person] = []
@Published var searchText: String = "" {
didSet {
if searchText.isEmpty {
filteredPeople = originalPeople
} else {
filteredPeople = originalPeople.filter { $0.name.lowercased().contains(searchText.lowercased()) }
}
}
}
init() {
self.filteredPeople = originalPeople
}
}
struct ContentView: View {
@ObservedObject var viewModel = ViewModel()
var body: some View {
NavigationStack {
List {
ForEach($viewModel.filteredPeople, id: \.name) { person in
VStack(alignment: .leading) {
Text(person.wrappedValue.name)

I have a SwiftuI App which includes an App Clip. There is one target for the iOS app and one for the App Clip. All good.
But I want to create a new target for the test flight app so that test users can distinguish it from the App Store app. E.g. Test Flight app has a different icon asset file in the target but is identical in all other aspects.
However, when I try to build the test flight target I see the message:
The com.apple.developer.parent-application-identifiers entitlement (...]') of an App Clip must match the application-identifier entitlement ('...') of its containing parent app.
This implies that I’d have to change the entitlement of the app clip, which would mess up the production version so I clearly don’t want to go that route.
Any ideas how to overcome this conflict?
I've got a problem with compatibility with Swift6 in iOS app that I have no idea how to sort it out.
That is an extract from my main app file
@MainActor
@main struct LangpadApp: App {
...
@State private var notificationDataProvider = NotificationDataProvider()
@UIApplicationDelegateAdaptor(NotificationServiceDelegate.self) var notificationServiceDelegate
var body: some Scene {
WindowGroup {
TabView(selection: $tabSelection) {
...
}
.onChange(of: notificationDataProvider.dateId) { oldValue, newValue in
if !notificationDataProvider.dateId.isEmpty {
tabSelection = 4
}
}
}
}
init() {
notificationServiceDelegate.notificationDataProvider = notificationDataProvider
}
}
and the following code shows other classes
@MainActor
final class NotificationServiceDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate
{
var notificationDataProvider: NotificationDataProvider?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -&gt; Bool {
UNUserNotificationCenter.current().delegate = self
return true
}
func setDateId(dateId: String) {
if let notificationDataProvider = notificationDataProvider {
notificationDataProvider.dateId = dateId
}
}
nonisolated func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse) async {
// After user pressed notification
let content = response.notification.request.content
if let dateId = content.userInfo["dateId"] as? String {
await MainActor.run {
setDateId(dateId: dateId)
}
}
}
nonisolated func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification) async -&gt; UNNotificationPresentationOptions {
// Before notification is to be shown
return [.sound, .badge, .banner, .list]
}
}
@Observable
final public class NotificationDataProvider : Sendable {
public var dateId = ""
}
I have set Strict Concurrency Checking to 'Complete.' The issue I'm facing is related to the delegate class method, which is invoked after the user presses the notification.
Current state causes crash after pressing notification. If I remove "nonisolated" keyword it works fine but I get the following warning
Non-sendable type 'UNNotificationResponse' in parameter of the protocol requirement satisfied by main actor-isolated instance method 'userNotificationCenter(_:didReceive:)' cannot cross actor boundary; this is an error in the Swift 6 language mode
I have no idea how to make it Swift6 compatible. Does anyone have any clues?
Recently I've made 1 character mistake in my code and have hard time during searching what was the problem.
Basically I forgot to set dot near one of the frame modifiers and compiler did not warn me, but during app running I got 100% CPU and rocket increase of RAM (on real app). Feels like recursion, but no any hint in call stack inside Xcode on crash stop.
struct BadView: View {
var body: some View {
Color.red
frame(height: 36)
}
}
I would like to see at least warning for such cases. Problem may look simple on this small example, but if you added 1k+ lines after last compilation - searching this type of errors could be problematic when you have no idea what to search.

I am using the simulator to launch my app and can see AppDelegate related logs but I am not seeing any SceneDelegate logs (I suppose because it is not being initialized nor called).
I have tried restarting the computer/Xcode, clean and rebuild the application but none of the things I tested work.
Is there any part of my code wrong? Any other idea here?
I've encountered an issue where storing a throws(PermissionError) closure as a property inside a SwiftUI View causes a runtime crash on iOS 17, while it works correctly on iOS 18.
Here’s an example of the affected code:
enum PermissionError: Error {
case denied
}
struct PermissionCheckedView<AllowedContent: View, DeniedContent: View>: View {
var protectedView: () throws(PermissionError) -> AllowedContent
var deniedView: (PermissionError) -> DeniedContent
init(
@ViewBuilder protectedView: @escaping () throws(PermissionError) -> AllowedContent,
@ViewBuilder deniedView: @escaping (PermissionError) -> DeniedContent
) {
self.protectedView = protectedView
self.deniedView = deniedView
}
public var body: some View {
switch Result(catching: protectedView) {
case .success(let content): content
case .failure(let error): deniedView(error)
}
}
}
@main
struct TestApp: App {
var body: some Scene {
WindowGroup {
PermissionCheckedView {
} deniedView: { _ in
}
}
}
}
Specifically this is the stack trace (sorry for the picture I didn't know how to get the txt):
If I use var protectedView: () throws -> AllowedContent without typed throws it works.
Hi! While working on my Swift Student Challenge submission it seems that I found a race condition (TOCTOU) bug in SwiftUI when using sheets, and I'm not sure if this is expected behaviour or not.
Here's an example code:
import SwiftUI
struct ContentView: View {
@State var myVar: Int?
@State private var presentSheet: Bool = false
var body: some View {
VStack {
// Uncommenting the following Text() view will "fix" the bug (kind of, see a better workaround below).
// Text("The value is \(myVar == nil ? "nil" : "not nil")")
Button {
myVar = nil
} label: {
Text("Set value to nil.")
}
Button {
myVar = 1
presentSheet.toggle()
} label: {
Text("Set value to 1 and open sheet.")
}
}
.sheet(isPresented: $presentSheet, content: {
if myVar == nil {
Text("The value is nil")
.onAppear {
print(myVar) // prints Optional(1)
}
} else {
Text("The value is not nil")
}
})
}
}
When opening the app and pressing the open sheet button, the sheet shows "The value is nil", even though the button sets myVar to 1 before the presentSheet Bool is toggled.
Thankfully, as a workaround to this bug, I found out you can change the sheet's view to this:
.sheet(isPresented: $presentSheet, content: {
if myVar == nil {
Text("The value is nil")
.onAppear {
if myVar != nil {
print("Resetting View (TOCTOU found)")
let mySwap = myVar
myVar = nil
myVar = mySwap
}
}
} else {
Text("The value is not nil")
}
})
This triggers a view refresh by setting the variable to nil and then to its non-nil value again if the TOCTOU is found.
Do you think this is expected behaivor? Should I report a bug for this? This bug also affects .fullScreenCover() and .popover().

Hi! I'm experimenting with the Entry macro in a SwiftUI app. I'm a little confused about how to stored a defaultValue to prevent extra work from creating this more than once.
A "legacy" approach to defining an Environment variable looks something like this:
struct StoredValue {
var value: String {
"Hello, world!"
}
init() {
print("StoredValue.init()")
}
}
extension EnvironmentValues {
var storedValue: StoredValue {
get {
self[StoredValueKey.self]
}
set {
self[StoredValueKey.self] = newValue
}
}
struct StoredValueKey: EnvironmentKey {
static let defaultValue = StoredValue()
}
}
The defaultValue is a static stored property.
Here is a "modern" approach using the Entry macro:
struct ComputedValue {
var value: String {
"Hello, world!"
}
init() {
print("ComputedValue.init()")
}
}
extension EnvironmentValues {
@Entry var computedValue: ComputedValue = ComputedValue()
}
From the perspective of the product engineer, it looks like I am defining another stored defaultValue property… but this actually expands to a computed property:
extension EnvironmentValues {
var computedValue: ComputedValue {
get {
self[__Key_computedValue.self]
}
set {
self[__Key_computedValue.self] = newValue
}
}
private struct __Key_computedValue: SwiftUICore.EnvironmentKey {
static var defaultValue: ComputedValue {
get {
ComputedValue()
}
}
}
}
If I tried to use both of these Environment properties in a SwiftUI component, it looks like I can confirm the computedValue is computing its defaultValue several times:
@main
struct EnvironmentDemoApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
struct ContentView: View {
@Environment(\.computedValue) var computedValue
@Environment(\.storedValue) var storedValue
var body: some View {
VStack {
Image(systemName: "globe")
.imageScale(.large)
.foregroundStyle(.tint)
Text("Hello, world!")
}
.padding()
}
}
And then when I run the app:
ComputedValue.init()
StoredValue.init()
ComputedValue.init()
ComputedValue.init()
ComputedValue.init()
ComputedValue.init()
ComputedValue.init()
ComputedValue.init()
ComputedValue.init()
Is there any way to use the Entry macro in a way that we store the defaultValue instead of computing it on-demand every time?
Hi,
Does the iPad Playgrounds app act completely the same way as a MacBook Playground?
I am developing my app on a 2020 MacBook Air M1 using Swift Playgrounds. However, since the testing is going to be done on an iPad Swift Playgrounds, I was worried if my playground would work, since it relies heavily on the screen size etc.
My app runs completely perfect on MacBook Playrgounds, but doesn't work on the iPad simulator on Xcode.
Hello!
How can I set appAccountToken when I'm using the new SwiftUI view SubscriptionStoreView for subscription?
Previously I was able to set it as a purchase option here https://developer.apple.com/documentation/storekit/product/purchase(options:) but I don't see purchase options with SubscriptionStoreView.
Thank you,

The easiest way to explain this is to show it. On any device, open Maps, set it to Driving (which will show traffic). Go to Baltimore Maryland. In the water just south east of the city there is a bridge (Francis Scott Key Bridge). . On Apple Maps the road is colored dark red.
At certain zoom levels, there is a "button" (red circle with a white - in it). When you click on that "button", it says 1 Advisory (Road Closed).
How do I show this "button" on my map. My map shows the dark red color, but no "button" appears.
The only "advisory" that I've been able to find is when you create a route. Of course you can't create a route over a road that fell into the water.
struct ContentView: View {
@State private var position = MapCameraPosition.region(
MKCoordinateRegion(
center: CLLocationCoordinate2D(latitude: 39.22742855118304, longitude: -76.52228412310761),
span: MKCoordinateSpan(latitudeDelta: 0.05407607689684113, longitudeDelta: 0.04606660133347873)
)
)
var body: some View {
Map(position: $position)
.mapStyle(.standard(pointsOfInterest: .all, showsTraffic: true))
.cornerRadius(25)
}
}
Is this a WCDWAD, or is there a way to show the "button"

I have a SwiftUI View I've introduced to a UIKit app, using UIHostingController. The UIView instance that contains the SwiftUI view is animated using auto layout constraints. In this code block, when a view controller's viewDidAppear method I'm creating the hosting controller and adding its view as a subview of this view controller's view, in addition to doing the Container View Controller dance.
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let hostingViewController = UIHostingController(rootView: TestView())
hostingViewController.view.translatesAutoresizingMaskIntoConstraints = false
addChild(hostingViewController)
view.addSubview(hostingViewController.view)
let centerXConstraint = hostingViewController.view.centerXAnchor.constraint(equalTo: view.centerXAnchor)
let topConstraint = hostingViewController.view.topAnchor.constraint(equalTo: view.topAnchor)
widthConstraint = hostingViewController.view.widthAnchor.constraint(equalToConstant: 361)
heightConstraint = hostingViewController.view.heightAnchor.constraint(equalToConstant: 342)
NSLayoutConstraint.activate([centerXConstraint, topConstraint, widthConstraint, heightConstraint])
hostingViewController.didMove(toParent: self)
self.hostingViewController = hostingViewController
}
I add a button to the UI which will scale the UIHostingViewController by adjusting its height and width constraints. When it's tapped, this action method runs.
@IBAction func animate(_ sender: Any) {
widthConstraint.constant = 120.3
heightConstraint.constant = 114.0
UIView.animate(withDuration: 0.5) {
self.view.layoutIfNeeded()
}
}
The problem is, the SwiftUI view's contents "jump" at the start of the animation to the final height, then animate into place. I see this both using UIView.animate the UIKit way, or creating a SwiftUI animation and calling `UIView.
What else do I need to add to make this animate smoothly?
We are trying to write an iOS app that supports regular and constrained widths using a TabView with .tabViewStyle(.sidebarAdaptable). On the surface this seems like a great way to write an app that supports all the different widths that your app may run in. Especially since Stage Manager and Apple Vision have made it easy for users to resize your apps window while it is running.
We are facing many challenges though. I will give a brief one liner of each below, but to truly experience them you need to run the sample app, or watch the sample videos included.
Issues
Basic TabView Issues
Double Navigation Bar: When tabs are collapsed into a "More" tab, there's an unwanted double navigation bar
Selection Sync: Tab selection gets out of sync when switching between narrow/wide layouts through the "More" tab
TabView Crash
Fatal crash occurs when resizing window to narrow width while Tab 5 is selected
Error: SwiftUI/SidebarAdaptableTabViewStyle_iOS.swift:482: Fatal error: Tried to update with invalid selection value
Section Handling Issues
Section Display Bug: Bottom tabs incorrectly show section names instead of tab names in narrow width
Tab Selection Mismatch: Tab identifiers don't match selected tabs in narrow width mode
Customization Issues
Inconsistent "Edit" button behavior in More tab
Unable to properly disable tab customization

Hello togehter,
i do have the following question.
If I have my App run in landscape mode and a sheet view get's called, will it be possible to switch automatically from landscape mode in portrait mode and fix this device orientation?
Once the sheet view get's dismissed or closed, the original view will come back and the device orientation shall switch back to landscape mode.
Thanks you so much for your help!
I want to add a tool bar (setting search )to my app just like the apple file app using pure swiftUI, is it possible, if not, can i using a UIKit to implement it.
struct MainView: View {
var body: some View {
TabView {
Tab("View 1", systemImage: "square.grid.3x2") {
View1()
}
Tab("View 2", systemImage: "square.grid.2x2") {
View2()
}
}
.tabViewStyle(.sidebarAdaptable)
}
I found an issue when implementing an alert with a TextField to input a name. I want the action button to be disabled until a name has been entered, but the action block is never executed when the button has become enabled and pressed. The problem seems to appear only when name is initially an empty string. Tested with iOS 17.0.
struct MyView: View {
@State private var name = ""
var body: some View {
SomeView()
.alert(...) {
TextField("Name", text: $name)
Button("Action") {
// Action
}.disabled(name.isEmpty)
Button("Cancel", role: .cancel) {}
}
}
}
