Hi, I was trying to understand how swift manages it memory just wanted to verify my understanding on it. For Value Types i.e. Struct ARC (Automatic Reference Counting) is not there, Memory is Managed/Confined on the basis of scope of that Variable. And For Struct whenver we do assignment a Copy is been created. For Classes, Swift Manages Memroy with the help of ARC i.e. whenever I create a instance of class its reference count get increased and when we assign same instance to new variable then it also result in increment of Reference Count. The Memory will get deallocated when all the variables pointing to that object are no longer in use.

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.

Following the latest Command Line Tools update, the swift-nio library (https://github.com/apple/swift-nio) causes my program to segfault. The function where the error occurs is runIfActive, which is executed with the following error: Thread 12: EXC_BAD_ACCESS (code=1, address=0x4) swift version: swiftlang-6.0.0.7.6 clang-1600.0.24.1 NIO version: 2.70.0

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?

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

I have an 8th generation iPad, now updated with iPadOS 16.2 (20C65) and I have an issue that I also saw on earlier 16.* betas. Task is not executing at all. This is so frustrating because I have adopted async/await in my app, I support iOS 15+, everything was working fine but now that stuff inside Task { } is not executed my app seems to be broken. (Note: my main device is an iPhone 11, still on iOS 16.0, and it works fine there.) It is also frustrating to see no other developers are complaining about this, like it happens only with my app. I have debugged with print statements and breakpoints and I can say for sure that stuff is not executing. Does anybody have any ideas? Anything else I can try? FB11866066

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

Hi everyone, I'm encountering an issue while testing a subscription purchase with a promotional offer using StoreKit in the Xcode debug environment. I’ve created a subscription in the StoreKit configuration file and added a promotional offer. However, when I attempt to make a purchase with the promotional offer, the process fails, and I receive an alert with the message: "Unable to purchase" "Contact the developer for more information." Here’s the error that is printed in the Xcode logs: Purchase did not return a transaction: Error Domain=ASDErrorDomain Code=3903 "Received failure in response from Xcode" UserInfo={NSDebugDescription=Received failure in response from Xcode, NSUnderlyingError=0x303346b50 {Error Domain=AMSErrorDomain Code=305 "Server Error" UserInfo={NSLocalizedDescription=Server Error, AMSServerErrorCode=3903, AMSServerPayload={ "cancel-purchase-batch" = 1; dialog = { defaultButton = ok; explanation = "Contact the developer for more information.\n\n[Environment: Xcode]"; initialCheckboxValue = 1; "m-allowed" = 0; message = "Unable to Purchase"; okButtonString = OK; }; dsid = 17322632127; failureType = 3903; jingleAction = inAppBuy; jingleDocType = inAppSuccess; pings = ( ); }, AMSURL=http://localhost:49300/WebObjects/MZBuy.woa/wa/inAppBuy, AMSStatusCode=200, NSLocalizedFailureReason=The server encountered an error}}} Has anyone encountered a similar issue, or does anyone have insights into what might be causing this? I’m using StoreKit 2 methods for handling subscriptions, and this error only occurs when attempting to apply the promotional offer. Any help or suggestions would be greatly appreciated! Thanks in advance!

Hi all, I'm trying to implement starting Live Activities with push notifications according to this article: https://developer.apple.com/documentation/activitykit/starting-and-updating-live-activities-with-activitykit-push-notifications I'm using Xcode 15.1 beta 3, I have run my tests on a physical device with iOS 17.2 as well as the simulator with iOS 17.2 My problem is I can't seem to be able to get the pushToStartToken needed to start the live activities. I have subscribed to the pushToStartTokenUpdates but I never get any updates. Here is the code I used: Task { do { for try await data in Activity<DailyGoalActivityAttributes>.pushToStartTokenUpdates { let token = data.map {String(format: "%02x", $0)}.joined() print("Activity token: \(token)") } } catch { print(error) } } Any help would be greatly appreciated. Thanks, HS

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?

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.

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.

I noticed a change from previous betas when I attempted to compile my code with Xcode 16 beta 5. If I have a class that is MainActor isolated, and it overrides init(), it looks like this init is always considered nonisolated now, even for a MainActor isolated class. This was not the case before. For example, I have a class that inherits from NSScroller. It defines a default initializer init() which calls the designated initializer - super.init(frame:CGRect()). This is apparently not allowed right now. If that's the case, how can one even default-initialize a class??? It also doesn't let me initialize other properties, since everything is MainActor isolated. Here's an abbreviated example. class MyCustomScroller : NSScroller { init () { super.init(frame: CGRect()) scrollerStyle = .overlay alphaValue = 0 } } This was allowed in prior betas. However, in beta 5, all 3 lines of my init generates an error such as: Call to main actor-isolated initializer 'init(frame:)' in a synchronous nonisolated context or Main actor-isolated property 'scrollerStyle' can not be mutated from a nonisolated context Is it just no longer possible to default-initialize MainActor classes, such as NSViews, now? The first line is particularly problematic because if I change it to just call super.init() then I get this error instead: Must call a designated initializer of the superclass 'NSScroller' You must call the designated initializer ... oh wait, we won't let you. Too bad.

I am generating an SKTexture with a GKNoiseMap. When I look at the texture in a swift playground, it has the expected colours. But when I apply the texture to a material and render it in a SCNView, the colours are different (colours appear too bright). What am I doing wrong? Swift playground to reproduce the issue (look at the texture variable in the playground and compare to rendered image). - https://developer.apple.com/forums/content/attachment/68210adc-98e9-4984-bca7-01f6e658d555
