Considering below dummy codes:
@MainActor var globalNumber = 0
@MainActor
func increase(_ number: inout Int) async {
// some async code excluded
number += 1
}
class Dummy: @unchecked Sendable {
@MainActor var number: Int {
get { globalNumber }
set { globalNumber = newValue }
}
@MainActor
func change() async {
await increase(&number) //Actor-isolated property 'number' cannot be passed 'inout' to 'async' function call
}
}
I'm not really trying to make an increasing function like that, this is just an example to make everything happen. As for why number is a computed property, this is to trigger the actor-isolated condition (otherwise, if the property is stored and is a value type, this condition will not be triggered).
Under these conditions, in function change(), I got the error: Actor-isolated property 'number' cannot be passed 'inout' to 'async' function call.
My question is: Why Actor-isolated property cannot be passed 'inout' to 'async' function call? What is the purpose of this design? If this were allowed, what problems might it cause?

Are there any plans to add RBI support (the sending keyword) to the OSAllocatedLock interface? So it could be used with non-sendable objects without surrendering to the unchecked API
I have added 2 command line tools in my swiftUI app for macOS, it was working fine locally, but it gives error when i try to make archive of it. I am not sure about the reason, but it was related to sandboxing the command line tools, after this i have tried multiple solutions but i am unable to resolve this issue, how should i handle the helper command line tools

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.
For some reason, I can't attach a video, so I can only show a screenshot
Hi, is there any way to use front camera to do the motion capture?
I want recognize if the user raised there hands up with the front camera on iPhone.
I was able to do it with the back camera, not the front.
Also, if there is any sample code, or document, I would be super happy.
Waiting for your reply!!

Build the archive, validating and uploading it to App Store Connect - TestFlight is successful from Xcode (16.0, macOS 15.1.1). Although after that the build is rejected stating :
ITMS-90429: Invalid Swift Support - The files libswiftCoreFoundation.dylib, libswiftCoreData.dylib, libswiftCore.dylib, libswiftFoundation.dylib, libswift_Concurrency.dylib, libswiftObjectiveC.dylib aren’t at the expected location /Payload/Runner.app/Frameworks. Move the file to the expected location, rebuild your app using the current public (GM) version of Xcode, and resubmit it.
Cross checked the Archive and .ipa file, where we found that the mentioned .dylib files are actually present inside the "/Payload/Runner.app/Frameworks" folder, and all the ".dylib" files are also present in the "SwiftSupport/iphoneos" folder.
Scenario : using tdLib compilation "libtdjson.xcframework" (embedded & signed) for ios arm64 placed under "Framworks", in my Flutter application, calling methods via "Method Channels", interacting with AppDelegate.swift file where the tdLib methods are being called from the compiled library.
All "swift support settings" are enabled in Xcode while archiving and building the application.
Just learning Swift and SwiftUI, having fun in Xcode. I have the following custom view defined, but when I try to test it, the information doesn't get updated as I expect. When I use the button defined INSIDE the custom view, the update works as expected. When I use the button defined in the Preview body, it doesn't. The "lines" variable of the custom view appears not to be updated in that case.
I know I'm missing something fundamental here about either view state binding or the preview environment, but I'm stumped. Any ideas?
import SwiftUI
struct ConsoleView: View {
var maxLines : Int = 26
private enum someIDs { case textID}
@State private var numLines : Int = 0
@State var lines = "a\nb\nc\n"
var body: some View {
VStack(alignment: .leading, spacing:0 ) {
ScrollViewReader { proxy in
ScrollView {
Button("Scroll to Bottom") {
withAnimation {
proxy.scrollTo(someIDs.textID, anchor: .bottom)
}
}
Text(lines)
.id(someIDs.textID)
.multilineTextAlignment(.leading)
.frame(maxWidth: .infinity, alignment: .bottomLeading)
.padding()
.onChange ( of: lines) {
withAnimation {
proxy.scrollTo( someIDs.textID, anchor: .bottom)
}
}
}
Button("Add more") {
writeln("More")
//writeln(response)
}
}
}
}
private func clipIfNeeded () {
if (numLines>=maxLines) {
if let i = lines.firstIndex(of: "\n") {
lines = String(lines.suffix( from: lines.index(after:i)))
}
}
}
func writeln ( _ newText : String) {
print("adding '\(newText)' to lines")
//clipIfNeeded()
write( newText )
write("\n")
numLines += 1
print(lines)
}
func write ( _ newText : String) {
lines += newText
}
}
#Preview {
VStack() {
var myConsole = ConsoleView(lines: "x\ny\nz\n")
myConsole
Button("Add stuff") {
myConsole.writeln("Stuff")
}
}
}
I'm getting a fatal error in a preview:
fatalError in Environment+Objects.swift at line 34.
Anyone any idea how to find this file
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)
Toggle("Favorite", isOn: person.isFavorite)
}
}
}
.navigationTitle("Contacts")
}
.searchable(text: $viewModel.searchText)
}
}
#Preview {
ContentView()
}```
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) -> 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 -> 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?

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?
Hey there,
i implemented live activity in my app and iam trying to start the live activity from push notification, updates works fine even when the app is in background but starting the activity creating issue mostly on background and kill mode when i check the delivery of live activity on cloudkit console it says stored for device power considerations.

Hey,
I would love to access the users Contact (ie. the Me Card)
Apple recently released the Invites app and within this app you can find the users Contacts Photo. I tried to replicate this behaviour but I currently need to match based on a name or email or something else. I have no idea how to receive this data because when using the Invites app I only remember the app asking for Contacts permission and nothing else so far.
let store = CNContactStore()
let keysToFetch = [CNContactImageDataAvailableKey, CNContactImageDataKey, CNContactThumbnailImageDataKey] as [CNKeyDescriptor]
let email = "test@test.de"
let predicate = CNContact.predicateForContacts(matchingEmailAddress: email)
do {
let contacts = try store.unifiedContacts(matching: predicate, keysToFetch: keysToFetch)
let imageDatas: [Data] = contacts.compactMap { $0.imageData }
self.images = imageDatas.map { UIImage(data: $0) ?? UIImage() }
} catch {
print("Error fetching contacts: \(error)")
}
This is how I am retrieving the Image. MAYBE someone can help me out.
Thank you so far

I’m working on a macOS app, written in Swift. My goal is to record audio from an external microphone, e.g., one connected via USB.
For this, I’m using an AVCaptureSession and recording its output with an AVAssetWriter. This works perfectly in principle (and reliably with internal microphones, for example).
The problem occurs after my app has successfully completed the first recording and I then want to make additional recordings (which makes me think it might be process-dependent, because it works again after restarting the app).
The problem: Noisy or distorted-sounding audio files. In addition, the following error message appears in the Console from CoreAudio / its AudioConverter:
Input data proc returned inconsistent 512 packets for 2048 bytes; at 3 bytes per packet, that is actually 682 packets
It is easy to reproduce. This problem is reproducible even if I don’t configure the AVAssetWriter manually and instead let it receive its audioSettings using a preset from an AVOutputSettingsAssistant. I’m running on macOS 15.0 (24A335).
I’ve filed a feedback including a demo project → FB15333298 🎟️
I would greatly appreciate any help!
Have a great day,
Martin
Swift assist has been announced by apple this year.
I have waited Xcode 16.2 release before posting this because I was still hopping for swift assist this year but apple DIDN'T release swift assist and they haven't post anything about swift assist reported or something...
What's going to happen with swift assist? Coming next year?
In the header for UIViewController, the method dismissViewControllerAnimated is declared like this:
- (void)dismissViewControllerAnimated: (BOOL)flag completion: (void (^ __nullable)(void))completion NS_SWIFT_DISABLE_ASYNC API_AVAILABLE(ios(5.0));
NS_SWIFT_DISABLE_ASYNC means that there's no async version exposed like there would normally be of a method that exposes a completion handler. Why is this? And is it unwise / unsafe for me to make my own async version of it using a continuation?
My use case is that I want a method that will sequentially dismiss all view controllers presented by a root view controller. So I could have this extension on UIViewController:
extension UIViewController {
func dismissAsync(animated: Bool) async {
await withCheckedContinuation { continuation in
self.dismiss(animated: animated) {
continuation.resume()
}
}
}
func dismissPresentedViewControllers() async {
while self.topPresentedViewController != self {
await self.topPresentedViewController.dismissAsync(animated: true)
}
}
var topPresentedViewController: UIViewController {
var result = self
while result.presentedViewController != nil {
result = result.presentedViewController!
}
return result
}
I have a SwiftUI project which has the following hierarchy:
IOSSceneDelegate (App target) - depends on EntryPoint and Presentation static libs.
Presentation (Static library) - Depends on EntryPoint static lib. Contains UI related logic and updates the UI after querying the data layer.
EntryPoint (Static library) - Contains the entry point, AppDelegate (for its lifecycle aspects) etc.
I've only listed the relevant targets here.
SceneDelegate was initially present in EntryPoint library, because the AppDelegate references it when a scene is created.
public func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Set the SceneDelegate dynamically
let sceneConfig: UISceneConfiguration = UISceneConfiguration(name: "mainWindow", sessionRole: connectingSceneSession.role)
sceneConfig.delegateClass = SceneDelegate.self
return sceneConfig
}
The intent is to move the SceneDelegate to the Presentation library.
When moved, the EntryPoint library fails to compile because it's referencing the SceneDelegate (as shown above).
To remove this reference, I tried to set up the SceneDelegate in the old way - In the info.plist file, mention a SceneConfiguration and set the SceneDelegate in Presentation.
// In the Info.plist file
<key>UIApplicationSceneManifest</key>
<dict>
<key>UIApplicationSupportsMultipleScenes</key>
<true/>
<key>UISceneConfigurations</key>
<dict>
<key>UIWindowSceneSessionRoleApplication</key>
<array>
<dict>
<key>UISceneConfigurationName</key>
<string>Default Configuration</string>
<key>UISceneDelegateClassName</key>
<string>Presentation.SceneDelegate</string>
</dict>
</array>
</dict>
</dict>
// In the AppDelegate
public func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Refer to a static UISceneconfiguration listed in the info.plist file
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
As shown above, the Presentation.SceneDelegate is referred in the Info.plist file and the reference is removed from the AppDelegate (in EntryPoint library).
The app target compiles, but when I run it, the SceneDelegate is not invoked. None of the methods from the SceneDelegate (scene(_:willConnectTo:options:), sceneDidDisconnect(_:), sceneDidEnterBackground(_:) etc.) are invoked. I only get the AppDelegate logs.
It seems like the Configuration is ignored because it was incorrect. Any thoughts? Is it possible to move the SceneDelegate in this situation?
For my app I've created a Dictionary that I want to persist using AppStorage
In order to be able to do this, I added RawRepresentable conformance for my specific type of Dictionary. (see code below)
typealias ScriptPickers = [Language: Bool]
extension ScriptPickers: @retroactive RawRepresentable where Key == Language, Value == Bool {
public init?(rawValue: String) {
guard let data = rawValue.data(using: .utf8),
let result = try? JSONDecoder().decode(ScriptPickers.self, from: data)
else {
return nil
}
self = result
}
public var rawValue: String {
guard let data = try? JSONEncoder().encode(self), // data is Data type
let result = String(data: data, encoding: .utf8) // coerce NSData to String
else {
return "{}" // empty Dictionary represented as String
}
return result
}
}
public enum Language: String, Codable, {
case en = "en"
case fr = "fr"
case ja = "ja"
case ko = "ko"
case hr = "hr"
case de = "de"
}
This all works fine in my app, however trying to run any tests, the build fails with the following:
Conflicting conformance of 'Dictionary<Key, Value>' to protocol 'RawRepresentable'; there cannot be more than one conformance, even with different conditional bounds
But then when I comment out my RawRepresentable implementation, I get the following error when attempting to run tests:
Value of type 'ScriptPickers' (aka 'Dictionary<Language, Bool>') has no member 'rawValue'
I hope Joseph Heller is out there somewhere chuckling at my predicament
any/all ideas greatly appreciated
Hey, I am building some widgets and I'm quite surprised that Swipe gestures for widgets is not supported. It means the user must sacrifice home screen real estate to view multiple widgets to receive the same information. Ideally, swiping left / right inside of the widget should give a developer access to present different views.
I realize that it means that a user would need to swipe outside of the widget, (or swipe to the beginning/end of the series of views inside of the widget) for the page to swipe, but I'd argue that this is the intuitive behavior of what widget scrollview would or should look like anyway.
