So I have this child class with a function that creates a perdetermined array of other classes. class DirectGame : GameParent { static func GetAllChallenges() -> Array<ChallengeParent>{ return [LockdownChallenge(game: self)] } } These other classes take in a GameParent class in the initalizer like so: class LockdownChallenge { var game : GameParent init(game: GameParent) { self.game = game } } However this line return [LockdownChallenge(game: self)] is throwing the error "Cannot convert value of type 'DirectGame.Type' to expected argument type 'GameParent'" How do I pass in a reference to DirectGame into the initalizer of ChallengeParent?

I am using withUnsafeMutablePointer to get raw pointer from Data. Once I get a Pointer I follow these steps: I create a Wrapper using that Pointer. After that I increase it ARC and pass it as a opaque to C++ When I was on First Step if my thread get suspended and after some time if it resumes then is there a possibility that the Memory will get freed due to ARC. Adding basic Code Flow depicting what i am doing. public class DataHolder { public init () {} public var data_wrapper : Data? } func InternalReceiveHandler (_ pContent : Data?) -> Void { var holder : DataHolder = DataHolder.init () withUnsafeMutablePointer (to : &pContent) { data_pointer in holder.data_wrapper = Data.init (noBytesCopy : data_pointer, count : no_of_bytes, deallocator : .none) return Unmanaged.passRetained (holder).toOpaque () } } Is there a possibility that when I am creating the wrapper my thread get suspended and when it get resumed the Memory the pointer was pointing can be freed by ARC.

I'm working on a Payment SDK integrating Storekit2 for Unity games. The workflow is as follows: build the swift project that exposes objective c interface to static libraries, then archive them into xcframework embed the xcframework into native unity plugin where we call objective-c functions from C# export the unity project to Xcode project build the game Xcode project When deployment target of swift project is set to iOS15 No matter what iOS version target is set in the game Xcode project, I got build error: Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibility56 When deployment target of swift project is set to iOS16 And set the deployment target of game project to iOS15 (I need to let the payment sdk to work on iOS15 as Storekit2 and swift concurrency shipped with iOS15). I can build the game Xcode project, and it works on iOS16+ device. But when I run on iOS15 device, I got runtime error: 2024-08-26 18:17:29.289078+0900 ***[1404:95780] Error loading /var/containers/Bundle/Application/123/***/Frameworks/UnityFramework.framework/UnityFramework: dlopen(/var/containers/Bundle/Application/123/***/Frameworks/UnityFramework.framework/UnityFramework, 0x0109): Symbol not found: (_objc_claimAutoreleasedReturnValue) Referenced from: '/private/var/containers/Bundle/Application/123/***/Frameworks/UnityFramework.framework/UnityFramework' Expected in: '/usr/lib/libobjc.A.dylib' 2024-08-26 18:17:29.418604+0900 ***[1404:95780] Error loading /var/containers/Bundle/Application/123/***/Frameworks/UnityFramework.framework/UnityFramework: dlopen(/var/containers/Bundle/Application/123/***/Frameworks/UnityFramework.framework/UnityFramework, 0x0109): Symbol not found: (_objc_claimAutoreleasedReturnValue) Referenced from: '/private/var/containers/Bundle/Application/123/***/Frameworks/UnityFramework.framework/UnityFramework' Expected in: '/usr/lib/libobjc.A.dylib' If I chose not to build framework into static libraries but dynamic ones, I can avoid this problem but Unity cannot handle dynamic libraries well when exporting to Xcode project so I have no choice here but to stick to static ones. minimum reproduction I made a minimum reproduction project to exclude the process of unity. a fresh new empty objective-c app project embed the xcframework built with target iOS15 call a function in the framework in applicationDidFinishLaunch set the deployment target of main target of the app project to iOS15. build the project I still get Undefined symbol: __swift_FORCE_LOAD_$_swiftCompatibility56 versions Xcode version 15.4 Test iOS device version 15.8

Do you have to compile your apps with Swift6 enabled to ship a production app when iOS18 is released?

Hi, How can I improve the CPU usage of my auto scrolling text (horizontal)? Currently I use very short timer Thank you Code: https://codeshare.io/Q8A1JJ

My app creates dynamic copies of UI controls that are based on a custom UIButton subclass using this legacy approach: let archivedButton = try NSKeyedArchiver.archivedData(withRootObject: self, requiringSecureCoding: false) guard let buttonDuplicate = try NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(archivedButton) as? UIWagerButton else {return nil } I am currently trying to work passed the deprecation of NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(data: Data) Per the guidance, I should be replacing that line with the following and ensuring that the custom class implements NSSecureCoding guard let buttonDuplicate = try NSKeyedUnarchiver.unarchivedObject(ofClass: UIWagerButton.self, from: archivedButton) else {return nil} However, while the code does compile and run, decoding the data reference throws the following error: value for key 'UIButtonStatefulContent' was of unexpected class 'NSMutableDictionary' I can only assume that if I get passed this specific property, there will be other properties that are also problematic. Question: Is this a bug? Or, am I now responsible for navigating the underlying property matrix of this UIControl to specifically, manually, handle the encoding and decoding of each of it's properties?

I am developing an iPhone app related to finance and currently I am using isCaptured value to prevent screen recording by checking the isCaptured value and if it is true then I blur the video recording. It was working fine while using UIScreen.main.isCaptured till iOS 17 . But for iOS 18 it became deprecated and it is not working any more. Below is the obj-c code block. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions { if (@available(iOS 11.0, *)) { BOOL isCaptured = [[UIScreen mainScreen] isCaptured]; if(isCaptured){ // Do the action for hiding the screen recording } } else{ // Fallback on earlier versions } return YES; } The replacement sceneCaptureState is working only for a scene-based app which uses UISceneDelegate lifecycle but it's not working for the old structure so now i have that problem, my iPhone app is very big and does not support scenes at all since we are following UIAppDelegate life cycle for years, what shall I do to prevent screen recording from iOS 18 onwards ? Note: My iPhone app does not support any scene configuration Please help me in this. Regards, Carol

We are using a 3rd party SDK which crashes on iOS 18 in certain scenarios. They say they need Apple to fix this bug ahead of release https://github.com/swiftlang/swift/issues/75952 but I'm skeptical since it is only a few weeks away most likely. The bug seems pretty bad so is there any chance it will be fixed before iOS 18? We aim for a same-day release so would be great to know if we need to remove the 3rd party SDK or not.

I’m trying to use BGProcessingTaskRequest to fetch step data in the background and send it. However, when I combine BGProcessingTaskRequest, HKObserverQuery, and healthStore.enableBackgroundDelivery, the results sometimes return zero. When I don’t schedule the BGProcessingTaskRequest, the data retrieved using HKObserverQuery and HKSampleQueryDescriptor is correct. // Register Smart Walking Sync Task func registerSmartWalkingSync() { #if !targetEnvironment(simulator) BGTaskScheduler.shared.register(forTaskWithIdentifier: BGTaskIdentifier.smartwalking.rawValue, using: nil) { task in guard let task = task as?

We have been successfully using the PTT (Push-to-Talk) framework in our application since the release of iOS 17. Audio is recorded by pressing a PTT button and speaking after the PTT framework initiates an AVAudioSession. While the PTT framework has generally worked well since the iOS 17 release, we have received reports that, on occasion, after the app has been idle for a while ( when I have seen it my phone has been in flightmode over night), it suddenly records only silent audio. This issue does not occur every time but sporadically. For users experiencing this problem, pressing the PTT button results in no “PTT framework start sound,” and only “empty sound” is recorded. The only solution to restore audio is restarting the device. Restarting the app alone is insufficient, though leaving the PTT channel and rejoining it also resolves the issue. I have reproduced the problem several times and observed that everything appears normal within the app. We receive an active AVAudioSession from the PTT framework, and it seems like the app is recording, but all recorded sound packets are silent. Upon reviewing logs from the phone (via the Console app), I noticed that the app is muted when starting the recording and unmuted after stopping the recording. For example: • Start recording ≈ 15:01:30 • Stop recording ≈ 15:01:44 • 15:01:30.124144+0100 audiomxd -CMSessionMgr- MXCoreSessionSetProperty: Session ‘sid:0xa80037, AppName(2717), ‘prim’’ isRecordingMuted updated to ‘1’ • 15:01:44.384208+0100 audiomxd -CMSessionMgr- MXCoreSessionSetProperty: Session ‘sid:0xa80037, AppName(2717), ‘prim’’ isRecordingMuted updated to ‘0’ When the system functions normally, the isRecordingMuted flag toggles between 0 and 1, but remains at 0 (non-muted) during recording. After stopping the recording, this state does not change anymore, unlike in the error state. There is no difference in behavior whether the app is in the foreground or background when starting the transmission, or whether the PTT framework’s “Talk” button is used once the device enters the “error state.” I have filed a bug report with logs provided on 28 November 2023 that is still open but no feedback. We now have customers that are reporting this issue again on 17.5.1 and its starting to be a big issue. Anyone else that have similar problems ?

I have a model "Objetive" with recursive iteration. In the user interface I can see all the Items, as expected, and I can expands all those that have children. However, I encounter an error when attempting to compact anyone with children that I have previously expanded, But only when I'm using Mac OS 15.1 On iOS 18.1 Works perfectly.

OK, so I'm trying to share some utils classes for logging. The problem is a use-case where I want to create a debug notification. However, inside the app, I want to show a popup instead if the app is showing, but I can't share that code because it uses UIApplication.shared.ApplicationState. I've tried gating it off with all sorts of methods, @available etc. but I get compilation error "unavailable for application extensions" Example of me trying: static func doNotification(_ header: String, message: String) { //so I'm trying to gate off the code that only can be called in an extension , and in addition I have @available below if(isAppExtension()){ doNotificationFromExtension(header, message: message) }else{ doNotificationFromApp(header, message: message) } } @available(iOSApplicationExtension, unavailable) static func doNotificationFromApp(_ header: String, message: String) { let state = UIApplication.shared.applicationState if state != .active { //my dialog handler in-app popup }else{ NotifUtils.createLocalNotification(message, header: header, category: NOTIFICATION_CATEGORY_DEBUG, playSound: false) } } //here I know that I'm in an extension, so app isn't showing - always local notification static func doNotificationFromExtension(_ header: String, message: String) { NotifUtils.createLocalNotification(message, header: header, category: NOTIFICATION_CATEGORY_DEBUG, playSound: false) } static func isAppExtension() -> Bool { return Bundle.main.executablePath?.contains(".appex/") ?? false } Is there any way to share the code like this? The reason I want to do this is because I have various live activity code that I'd want to re-use, but this is a show.-stopper.

Hello, I've been working on my macos app for months, today I opened XCode, and it's full of the same errors "Value of type 'URL' has no member 'url''" and "Cannot convert value of type 'Binding' to expected argument type 'CGFloat'". I didn't change ANYTHING, I didn't update nor remove anything, the 3rd party module I'm using didn't get updated, this is all out of the blue! I tried to clean the build folder, erase the derivated data, rebuild a new project, these errors won't go away...worst part is that another of my app use the same codes and there I see the errors but the app still compiles and build!!

Hello, I have a problem with the .onMove function. I believe I have set everything up properly. However, the moving does not seem to be working correctly. When I try to move the item, it is highlighted first, as it is supposed to be. Then, while I am moving it through the list, it disappears for some reason, and at the end of the move, it comes back to its initial place. (I use iOS 16.0 minimum, so I don't have to include the EditButton(). It works the same in the edit mode tho) import SwiftUI struct Animal: Identifiable { var id = UUID() var name: String } struct ListMove: View { @State var animals = [Animal(name: "Dog"), Animal(name: "Cat"), Animal(name: "Cow"), Animal(name: "Goat"), Animal(name: "Chicken")] var body: some View { List { ForEach(animals) { animal in Text(animal.name) } .onMove(perform: move) } } func move(from source: IndexSet, to destination: Int) { animals.move(fromOffsets: source, toOffset: destination) } } #Preview { ListMove() }

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?

I'm used to wait for expectations when using XCTest, but I'm completely stumped by the seemingly-absent option for expecting some parts of my code to be called in Swift Testing 🤔 Consider the following: protocol MyAPI { func getData() async throws -> String } class MockAPI: MyAPI { let stub: () async throws -> String init(stub: @escaping () async throws -> String = { "hello" }) { self.stub = stub } func getData() async throws -> String { try await stub() } } Which is being used in my view model: class MyViewModel: ObservableObject { private let api: MyAPI @Published var data: String init(api: MyAPI) { self.api = api } func refresh() async throws { self.data = try await api.getData() } } When I wrote tests in the past, I would simply override the stub of the MockAPI implementation and fulfill an expectation in there: class MyViewModelTests: XCTestCase { func testModelCallsAPIOnRefresh() async throws { let expectCallsAPI = expectation("Model should call API") let api = MockAPI { expectCallsAPI.fulfill() return "hello" } let model = MyViewModel(api: api) try await model.refresh() await fulfillment(of: [expectCallsAPI], timeout: 1) } } How would I go about checking that my model does indeed call the API when using Swift Testing?

Hey everyone, I'm working on implementing an AppLimit, where after accumulating x minutes of Screen Time for an app, it should be blocked. It works fine on the first day, but stops functioning correctly on subsequent days. What I'm Doing I start a 24/7 schedule with a DeviceActivityEvent that has a specified Screen Time threshold. In my DeviceActivityMonitor, I'm reacting to the eventDidReachThreshold. Once the accumulated time is reached, the app is blocked. This works as expected on the first day. Issues I'm Experiencing / Questions Second Day Issue: On the second day, the app is no longer blocked after the Screen Time threshold is reached, even though it worked on the first day. This leads me to suspect that a DeviceActivityEvent is "consumable". Is this correct? Pre-existing Screen Time Issue: If a user has already surpassed the Screen Time threshold before monitoring starts, the app isn't blocked once the schedule is set up. This leads to 2 issues: I would expect that the accumulated amount of time after starting the schedule would result in the call of eventDidReachThreshold. But it is never called It could also be the case that the previously accumulated time is being kept in mind, but that would mean the apps should be blocked, which isn't the case. Does the threshold account for accumulated Screen Time before the schedule begins? I haven't tested setting a limit of 10 minutes, accumulating 3 minutes of Screen Time, then starting the schedule and accumulating the remaining time, but I'm curious if anyone has encountered this behavior. Does anyone have an explanation for this behavior? Any help would be greatly appreciated!

Hi, As AppStorage does not support arrays, I found an extension online that allows for handling arrays of strings with AppStorage. However, in my use case, I need to handle arrays of boolean values. Below is the code. Any help would be greatly appreciated. extension Array: RawRepresentable where Element: Codable { public init?(rawValue: String) { guard let data = rawValue.data(using: .utf8), let result = try? JSONDecoder().decode([Element].self, from: data) else { return nil } self = result } public var rawValue: String { guard let data = try? JSONEncoder().encode(self), let result = String(data: data, encoding: .utf8) else { return "[]" } return result } }
