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, 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?

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.

After installing iOS 18.1 and iPados 18.1 we get a consuste failure when trying to add to our one to many data model. This was working well until we installed 18.1 when trying to add a entry to the many relationship we get this error Illegal attempt to map a relationship containing temporary objects to its identifiers.

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.

Hi, is there an intrinsic instruction to shift a vector from another a shift vector? thank

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 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

I have enabled runtime concurrency warnings to check for future problems concerning concurrency: Build Setting / Other Swift Flags: -Xfrontend -warn-concurrency -Xfrontend -enable-actor-data-race-checks When trying to call the async form of PHPhotoLibrary.shared().performChanges{} I get the following runtime warning: warning: data race detected: @MainActor function at ... was not called on the main thread in the line containing performChanges. My sample code inside a default Xcode multi platform app template is as follows: import SwiftUI import Photos @MainActor class FotoChanger{     func addFotos() async throws{         await PHPhotoLibrary.requestAuthorization(for: .addOnly)         try! await PHPhotoLibrary.shared().performChanges{             let data = NSDataAsset(name: "Swift")!.data             let creationRequest = PHAssetCreationRequest.forAsset()             creationRequest.addResource(with: .photo, data: data, options: PHAssetResourceCreationOptions())         }     } } struct ContentView: View {     var body: some View {         ProgressView()             .task{                 try! await FotoChanger().addFotos()             }     } } You would have to have a Swift data asset inside the asset catalog to run the above code, but the error can even be recreated if the data is invalid. But what am I doing wrong? I have not found a way to run perform changes, the block or whatever causes the error on the main thread. PS: This is only test code to show the problem, don't mind the forced unwraps.

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!!
