Here is my code: ` // A 3rd-party class I must use. class MySession{ init() async throws { // .. } } actor SessionManager{ private var mySession: MySession? // The MySession is not Sendable func createSession() async { do { mySession = try await MySession() log("getOrCreateSession() End, success.") } catch { log("getOrCreateSession() End, failure.") } } }` I get this warning: "Non-sendable type 'MySession' returned by implicitly asynchronous call to a nonisolated function cannot cross the actor boundary." How can this be fixed?

When swizzling NSURLRequest initialiser and returning a mutable copy, the original instance does not get deallocated and eventually gets leaked and a crash follows after that. Here's the swizzling setup: static func swizzleInit() { let initSel = NSSelectorFromString("initWithURL:cachePolicy:timeoutInterval:") guard let initMethod = class_getInstanceMethod(NSClassFromString("NSURLRequest"), initSel) else { return } let origInitImp = method_getImplementation(initMethod) let block: @convention(block) (AnyObject, Any, NSURLRequest.CachePolicy, TimeInterval) -> NSURLRequest = { _self, url, policy, interval in typealias OrigInit = @convention(c) (AnyObject, Selector, Any, NSURLRequest.CachePolicy, TimeInterval) -> NSURLRequest let origFunc = unsafeBitCast(origInitImp, to: OrigInit.self) let request = origFunc(_self, initSel, url, policy, interval) return request.tagged() } let newImplementation = imp_implementationWithBlock(block as Any) method_setImplementation(initMethod, newImplementation) } // create a mutable copy if needed and add a header private func tagged() -> NSURLRequest { guard let mutableRequest = self as? NSMutableURLRequest ?? self.mutableCopy() as? NSMutableURLRequest else { return self } mutableRequest.setValue("test", forHTTPHeaderField: "test") return mutableRequest } Then, we have a few test cases: // memory leak and crash func testSwizzleNSURLRequestInit() { let request = NSURLRequest(url: URL(string: "https://example.com")!) XCTAssertEqual(request.value(forHTTPHeaderField: "test"), "test") } // no crash, as the request is mutable, so no copy is created func testSwizzleNSURLRequestInit2() { let request = URLRequest(url: URL(string: "https://example.com")!) XCTAssertEqual(request.value(forHTTPHeaderField: "test"), "test") } // no crash, as the request is mutable, so no copy is created func testSwizzleNSURLRequestInit3() { let request = NSMutableURLRequest(url: URL(string: "https://example.com")!) XCTAssertEqual(request.value(forHTTPHeaderField: "test"), "test") } // no crash, as the new instance does not get deallocated // when the test method completes (?) var request: NSURLRequest? func testSwizzleNSURLRequestInit4() { request = NSURLRequest(url: URL(string: "https://example.com")!) XCTAssertEqual(request?.value(forHTTPHeaderField: "test"), "test") } It appears a memory leak occurs only when any other instance except for the original one is being returned from the initialiser. Is there a workaround to prevent the leak, while allowing for modifications of all requests?

Hi there, this is my first time posting here. I've heard that some of the apple developers are usually active on these forums, so I've decided to shoot my shot, because this question was driving me crazy for a few days now and nobody could yet give me a clear view on what's actually happening. Here is the first snippet of the code class Animal { var name = "Fischer" var command: () -> Void = { } deinit { print(#function, #line) } } do { var pet: Animal? = Animal() pet?.command = { print(pet?.name ?? "Bobby") } } This code causes a memory leak, because Reference 'pet' is created. Independent copy of the reference 'pet' is created inside the closure. now there are two references to the same object, which are 'pet' outside the closure and 'pet' inside the closure. As we exit the 'do' scope, the 'pet' reference is deleted, but ARC does not deallocate the object due to the strong reference 'pet', that is still referencing to the same object. And all of that causes a memory leak. Now here is the code, that is pretty similar, except for the fact, that we assign a nil to the 'pet' reference class Animal { var name = "Fischer" var command: () -> Void = { } deinit { print(#function, #line) } } do { var pet: Animal? = Animal() pet?.command = { print(pet?.name ?? "Bobby") } pet = nil } And boom! deinit is called, meaning that the object was deallocated, but how? Why was the object deallocated? If we are deleting the exact same reference, that was deleted by the end of the 'do' scope in the first snippet? Am I misunderstanding something? I really hope this post will find the right people, since I could not even find appropriate tags for that.

I generate images with command line apps in Swift on MacOS. Under the prior Xcode/MacOS my code had been running at the same performance for years. Converting to Swift 6 (no code changes) and running on Sequoia, I noticed a massive slowdown. Running Profile, I tracked it down to allow single line: var values = ContiguousArray<Double>(repeating: 0.0, count: localData.options.count) count for my current test case is 4, so its allocating 4 doubles at a time, around 40,000 times in this test. This one line takes 42 seconds out of a run time of 52 seconds. With the profile shown as: 26 41.62 s  4.8% 26.00 ms specialized ContiguousArray.init(_uninitializedCount:) 42 41.57 s  4.8% 42.00 ms _ContiguousArrayBuffer.init(_uninitializedCount:minimumCapacity:) 40730 40.93 s  4.7% 40.73 s _swift_allocObject_ 68 68.00 ms  0.0% 68.00 ms std::__1::pair<MallocTypeCacheEntry*, unsigned int> swift::ConcurrentReadableHashMap<MallocTypeCacheEntry, swift::LazyMutex>::find<unsigned int>(unsigned int const&, swift::ConcurrentReadableHashMap<MallocTypeCacheEntry, swift::LazyMutex>::IndexStorage, unsigned long, MallocTypeCacheEntry*) 7 130.00 ms  0.0% 7.00 ms swift::swift_slowAllocTyped(unsigned long, unsigned long, unsigned long long) which is clearly inside the OS allocator somewhere. What happened? Previously this would have taken closer to 8 seconds or so for the entire run.

Can i use c++ library with c library in swift app project Hello. I want to use a C++ library in my Swift app project. First, our company has an internal solution library. When built, it generates a Static Library in '.a' format, and we use it by connecting the library's Header to the App_Bridging_Header. There's no problem with this part. However, the new feature now includes C++. It also generates a Static Library in '.a' format. So, I tried to use the same method and created an App_Bridging_Header. But an error occurs, and I can't proceed. The first error occurs in the library file: 'iostream' file not found The second error occurs in the App_Bridging_Header: failed to emit precompiled header '/Users/kimjitae/Library/Developer/Xcode/DerivedData/ddddd-glmnoqrwdrgarrhjulxjmalpyikr/Build/Intermediates.noindex/PrecompiledHeaders/ddddd-Bridging-Header-swift_3O89L0OXZ0CPD-clang_188AW1HK8F0Q3.pch' for bridging header '/Users/kimjitae/Desktop/enf4/ddddd/ddddd/ddddd-Bridging-Header.h' Our library is developed in C++ using Xcode, and there's no problem when we run and build just the library project. The build succeeds, and the '.a' file is generated correctly. However, when we try to connect it with the app, the above problems occur. Could there be a problem because we also need to use the existing C library alongside this? The build is successful in an app project created with Objective-C.

We are getting a crash _dispatch_assert_queue_fail when the cancellationHandler on NSProgress is called. We do not see this with iOS 17.x, only on iOS 18. We are building in Swift 6 language mode and do not have any compiler warnings. We have a type whose init looks something like this: init( request: URLRequest, destinationURL: URL, session: URLSession ) { progress = Progress() progress.kind = .file progress.fileOperationKind = .downloading progress.fileURL = destinationURL progress.pausingHandler = { [weak self] in self?.setIsPaused(true) } progress.resumingHandler = { [weak self] in self?.setIsPaused(false) } progress.cancellationHandler = { [weak self] in self?.cancel() } When the progress is cancelled, and the cancellation handler is invoked. We get the crash. The crash is not reproducible 100% of the time, but it happens significantly often. Especially after cleaning and rebuilding and running our tests. * thread #4, queue = 'com.apple.root.default-qos', stop reason = EXC_BREAKPOINT (code=1, subcode=0x18017b0e8) * frame #0: 0x000000018017b0e8 libdispatch.dylib`_dispatch_assert_queue_fail + 116 frame #1: 0x000000018017b074 libdispatch.dylib`dispatch_assert_queue + 188 frame #2: 0x00000002444c63e0 libswift_Concurrency.dylib`swift_task_isCurrentExecutorImpl(swift::SerialExecutorRef) + 284 frame #3: 0x000000010b80bd84 MyTests`closure #3 in MyController.init() at MyController.swift:0 frame #4: 0x000000010b80bb04 MyTests`thunk for @escaping @callee_guaranteed @Sendable () -&gt; () at &lt;compiler-generated&gt;:0 frame #5: 0x00000001810276b0 Foundation`__20-[NSProgress cancel]_block_invoke_3 + 28 frame #6: 0x00000001801774ec libdispatch.dylib`_dispatch_call_block_and_release + 24 frame #7: 0x0000000180178de0 libdispatch.dylib`_dispatch_client_callout + 16 frame #8: 0x000000018018b7dc libdispatch.dylib`_dispatch_root_queue_drain + 1072 frame #9: 0x000000018018bf60 libdispatch.dylib`_dispatch_worker_thread2 + 232 frame #10: 0x00000001012a77d8 libsystem_pthread.dylib`_pthread_wqthread + 224 Any thoughts on why this is crashing and what we can do to work-around it?

I have a simple wrapper class around WCSession to allow for easier unit testing. I'm trying to update it to Swift 6 concurrency standards, but running into some issues. One of them is in the sendMessage function (docs here It takes [String: Any] as a param, and returns them as the reply. Here's my code that calls this: @discardableResult public func sendMessage(_ message: [String: Any]) async throws -&gt; [String: Any] { return try await withCheckedThrowingContinuation { (continuation: CheckedContinuation&lt;[String: Any], Error&gt;) in wcSession.sendMessage(message) { response in continuation.resume(returning: response) // ERROR HERE } errorHandler: { error in continuation.resume(throwing: error) } } } However, I get this error: Sending 'response' risks causing data races; this is an error in the Swift 6 language mode Which I think is because Any is not Sendable. I tried casting [String: Any] to [String: any Sendable] but then it says: Conditional cast from '[String : Any]' to '[String : any Sendable]' always succeeds Any ideas on how to get this to work?

I'm seeing a crash compiling with Swift 6 that I can reproduce with the following code. It crashes with "Incorrect actor executor assumption". Is there something that the compiler should be warning about so that this isn't a runtime crash? Note - if I use a for in loop instead of the .forEach closure, the crash does not happen. Is the compiler somehow inferring the wrong isolation domain for the closure? import SwiftUI struct ContentView: View { var body: some View { Text("Hello, world!") .task { _ = try? await MyActor(store: MyStore()) } } } actor MyActor { var credentials = [String]() init(store: MyStore) async throws { try await store.persisted.forEach { credentials.append($0) } } } final class MyStore: Sendable { var persisted: [String] { get async throws { return ["abc"] } } } The stack trace is: * thread #6, queue = 'com.apple.root.user-initiated-qos.cooperative', stop reason = signal SIGABRT frame #0: 0x0000000101988f30 libsystem_kernel.dylib`__pthread_kill + 8 frame #1: 0x0000000100e2f124 libsystem_pthread.dylib`pthread_kill + 256 frame #2: 0x000000018016c4ec libsystem_c.dylib`abort + 104 frame #3: 0x00000002444c944c libswift_Concurrency.dylib`swift::swift_Concurrency_fatalErrorv(unsigned int, char const*, char*) + 28 frame #4: 0x00000002444c9468 libswift_Concurrency.dylib`swift::swift_Concurrency_fatalError(unsigned int, char const*, ...) + 28 frame #5: 0x00000002444c90e0 libswift_Concurrency.dylib`swift_task_checkIsolated + 152 frame #6: 0x00000002444c63e0 libswift_Concurrency.dylib`swift_task_isCurrentExecutorImpl(swift::SerialExecutorRef) + 284 frame #7: 0x0000000100d58944 IncorrectActorExecutorAssumption.debug.dylib`closure #1 in MyActor.init($0="abc") at <stdin>:0 frame #8: 0x0000000100d58b94 IncorrectActorExecutorAssumption.debug.dylib`partial apply for closure #1 in MyActor.init(store:) at <compiler-generated>:0 frame #9: 0x00000001947f8c80 libswiftCore.dylib`Swift.Sequence.forEach((τ_0_0.Element) throws -> ()) throws -> () + 428 * frame #10: 0x0000000100d58748 IncorrectActorExecutorAssumption.debug.dylib`MyActor.init(store=0x0000600000010ba0) at ContentView.swift:27:35 frame #11: 0x0000000100d57734 IncorrectActorExecutorAssumption.debug.dylib`closure #1 in ContentView.body.getter at ContentView.swift:14:32 frame #12: 0x0000000100d57734 IncorrectActorExecutorAssumption.debug.dylib`closure #1 in ContentView.body.getter at ContentView.swift:14:32 frame #13: 0x00000001d1817138 SwiftUI`(1) await resume partial function for partial apply forwarder for closure #1 () async -> () in closure #1 (inout Swift.TaskGroup<()>) async -> () in closure #1 () async -> () in SwiftUI.AppDelegate.application(_: __C.UIApplication, handleEventsForBackgroundURLSession: Swift.String, completionHandler: () -> ()) -> () frame #14: 0x00000001d17b1e48 SwiftUI`(1) await resume partial function for dispatch thunk of static SwiftUI.PreviewModifier.makeSharedContext() async throws -> τ_0_0.Context frame #15: 0x00000001d19c10c0 SwiftUI`(1) await resume partial function for generic specialization <()> of reabstraction thunk helper <τ_0_0 where τ_0_0: Swift.Sendable> from @escaping @isolated(any) @callee_guaranteed @async () -> (@out τ_0_0) to @escaping @callee_guaranteed @async () -> (@out τ_0_0, @error @owned Swift.Error) frame #16: 0x00000001d17b1e48 SwiftUI`(1) await resume partial function for dispatch thunk of static SwiftUI.PreviewModifier.makeSharedContext() async throws -> τ_0_0.Context

Hi all, I am trying to use this guide to link directly to symbols in my documentation. But I am unable to get it to link to an Objective-C enum case. For example ``EnumNameType/EnumNameMyCase`` does not create a link. It works fine for method names, etc. I have tried all of the combinations I can think of, but I can't get it to work. Any help is much appreciated!

Hello Everyone, I have a use case where I wanted to interpret the "Data" object received as a part of my NWConnection's recv call. I have my interpretation logic in cpp so in swift I extract the pointer to the raw bytes from Data and pass it to cpp as a UnsafeMutableRawPointer. In cpp it is received as a void * where I typecast it to char * to read data byte by byte before framing a response. I am able to get the pointer of the bytes by using // Swift Code // pContent is the received Data if let content = pContent, !content.isEmpty { bytes = content.withUnsafeBytes { rawBufferPointer in guard let buffer = rawBufferPointer.baseAddress else { // return with null data. } // invoke cpp method to interpret data and trigger response. } // Cpp Code void InterpretResponse (void * pDataPointer, int pDataLength) { char * data = (char *) pDataPointer; for (int iterator = 0; iterator < pDataLength; ++iterator ) { std::cout << data<< std::endl; data++; } } When I pass this buffer to cpp, I am unable to interpret it properly. Can someone help me out here? Thanks :) Harshal

For my app I was trying to write some tests to ensure the functionality of all features. As I am using Xcode 16.0 I thought I might use Swift testing which was newly introduced and replaces XCTest. I created a new test target with Swift Testing and tried to run the first test, which was created automatically by the system. struct FinancialTests { @Test func testExample() async throws { #expect(true) } } Xcode is also showing the test diamond next to the function so I clicked on it to execute it. The app started to build and the build ended successfully. The the next step was testing. And after waiting for 10 minutes or so, no test was executed. First I thought maybe the test was not found, but in the test case overview all tests were shown: The run only shows this: Can someone help me to get this running. Many thanks!

As I migrate my apps to Swift 6 one by one, I am gaining a deeper understanding of concurrency. In the process, I am quite satisfied to see the performance benefits of parallel programming being integrated into my apps. At the same time, I have come to think that actor is a great type for addressing the 'data race' issues that can arise when using the 'singleton' pattern with class. Specifically, by using actor, you no longer need to write code like private let lock = DispatchQueue(label: "com.singleton.lock") to prevent data races that you would normally have to deal with when creating a singleton with a class. It reduces the risk of developer mistakes. import EventKit actor EKDataStore: Sendable { static let shared = EKDataStore() let eventStore: EKEventStore private init() { self.eventStore = EKEventStore() } } Of course, since a singleton is an object used globally, it can become harder to manage dependencies over time. There's also the downside of not being able to inject dependencies, which makes testing more difficult. I still think the singleton pattern is ideal for objects that need to be maintained throughout the entire lifecycle of the app with only one instance. The EKDataStore example I gave is such an object. I’d love to hear other iOS developers' opinions, and I would appreciate any advice on whether I might be missing something 🙏

Hey all! in my personal quest to make future proof apps moving to Swift 6, one of my app has a problem when setting an artwork image in MPNowPlayingInfoCenter Here's what I'm using to set the metadata func setMetadata(title: String? = nil, artist: String? = nil, artwork: String? = nil) async throws { let defaultArtwork = UIImage(named: "logo")! var nowPlayingInfo = [ MPMediaItemPropertyTitle: title ?? "***", MPMediaItemPropertyArtist: artist ?? "***", MPMediaItemPropertyArtwork: MPMediaItemArtwork(boundsSize: defaultArtwork.size) { _ in defaultArtwork } ] as [String: Any] if let artwork = artwork { guard let url = URL(string: artwork) else { return } let (data, response) = try await URLSession.shared.data(from: url) guard (response as? HTTPURLResponse)?.statusCode == 200 else { return } guard let image = UIImage(data: data) else { return } nowPlayingInfo[MPMediaItemPropertyArtwork] = MPMediaItemArtwork(boundsSize: image.size) { _ in image } } MPNowPlayingInfoCenter.default().nowPlayingInfo = nowPlayingInfo } the app crashes when hitting MPMediaItemPropertyArtwork: MPMediaItemArtwork(boundsSize: defaultArtwork.size) { _ in defaultArtwork } or nowPlayingInfo[MPMediaItemPropertyArtwork] = MPMediaItemArtwork(boundsSize: image.size) { _ in image } commenting out these two make the app work again. Again, no clue on why. Thanks in advance

Hi, After update to Xcode 16 a lot of errors happen, for example: import Foundation extension Collection {     func get(at i: Index) -&gt; Element? {         return indices.contains(i) ? self[i] : nil     } } Errors: Cannot find type 'Index' in scope Cannot find 'indices' in scope What is wrong? Thanks.

Issues Integrating FaceTec SDK into a Custom iOS Framework Hi Community, I am working on a custom iOS framework that integrates FaceTec SDK for biometric authentication, but I am facing issues with properly running the SDK within my framework. Below is the context and specific issues I need help with: Context: I have created a framework that includes a UIViewController called FinishViewController. This controller is responsible for managing the FaceTec SDK session. Below is a simplified snippet of the code used to initialize and handle FaceTec SDK: import UIKit import FaceTecSDK import LocalAuthentication class FinishViewController: UIViewController, URLSessionDelegate{ var utils: SampleAppUtilities! var latestProcessor: Processor! var latestExternalDatabaseRefID: String = "" var latestSessionResult: FaceTecSessionResult! var latestIDScanResult: FaceTecIDScanResult! @IBOutlet weak var elTelon: UIView! var isRealPerson = false var isNotSuccessful = false var isCancelled = false override func viewDidLoad() { super.viewDidLoad() utils = SampleAppUtilities(vc: self) // Initialize FaceTec SDK Config.initializeFaceTecSDKFromAutogeneratedConfig(completion: { initializationSuccessful in if(initializationSuccessful) { self.onFaceTecSDKInitializationSuccess() } else { self.onFaceTecSDKInitializationFailure() } }) DispatchQueue.main.asyncAfter(deadline: .now() + 2) { [self] in getSessionToken() { sessionToken in _ = LivenessCheckProcessor(sessionToken: sessionToken, fromViewController: self) .lvResponseDelegate = self //self.latestProcessor = AuthenticateProcessor(sessionToken: sessionToken, fromViewController: self) } } // Do any additional setup after loading the view. } func onFaceTecSDKInitializationFailure() { // Displays the FaceTec SDK Status to text field if init failed self.utils.displayStatus(statusString: "\(FaceTec.sdk.description(for: FaceTec.sdk.getStatus()))") } func onFaceTecSDKInitializationSuccess() { // self.utils.enableButtons(shouldEnable: true) // Set your FaceTec Device SDK Customizations. ThemeHelpers.setAppTheme(theme: utils.currentTheme) // Set the sound files that are to be used for Vocal Guidance. // Set the strings to be used for group names, field names, and placeholder texts for the FaceTec ID Scan User OCR Confirmation Screen. SampleAppUtilities.setOCRLocalization() let currentTheme = Config.wasSDKConfiguredWithConfigWizard ? "Config Wizard Theme" : "FaceTec Theme" utils.handleThemeSelection(theme: currentTheme) self.utils.displayStatus(statusString: "Initialized Successfully.") } func onComplete() { if !self.latestProcessor.isSuccess() { // Reset the enrollment identifier. self.latestExternalDatabaseRefID = ""; } } func getSessionToken(sessionTokenCallback: @escaping (String) -> ()) { let endpoint = Config.BaseURL + "/session-token" let request = NSMutableURLRequest(url: NSURL(string: endpoint)! as URL) request.httpMethod = "GET" // Required parameters to interact with the FaceTec Managed Testing API. request.addValue(Config.DeviceKeyIdentifier, forHTTPHeaderField: "X-Device-Key") request.addValue(FaceTec.sdk.createFaceTecAPIUserAgentString(""), forHTTPHeaderField: "User-Agent") request.addValue(FaceTec.sdk.createFaceTecAPIUserAgentString(""), forHTTPHeaderField: "X-User-Agent") let session = URLSession(configuration: URLSessionConfiguration.default, delegate: self, delegateQueue: OperationQueue.main) let task = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in // Ensure the data object is not nil otherwise callback with empty dictionary. guard let data = data else { print("Exception raised while attempting HTTPS call.") return } if let responseJSONObj = try? JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.allowFragments) as! [String: AnyObject] { if((responseJSONObj["sessionToken"] as? String) != nil) { sessionTokenCallback(responseJSONObj["sessionToken"] as! String) return } else { print("Exception raised while attempting HTTPS call.") } } }) task.resume() } func getLatestExternalDatabaseRefID() -> String { return latestExternalDatabaseRefID; } func setLatestSessionResult(sessionResult: FaceTecSessionResult) { latestSessionResult = sessionResult print("The latestSessionResult is: ", latestSessionResult!) } @IBAction func finish(_ sender: Any) { AppConfig.shared.intentosCaptura = 1 self.performSegue(withIdentifier: "unwindToRoot", sender: self) } } When I try to run the SDK, no initial compilation or runtime errors occur, but the SDK does not start as expected and there are no clear indications or errors in the console to help me diagnose the problem. I have checked the wiring of all the IBOutlet and IBAction, and everything seems to be in order. Are there any special considerations I should be aware of when integrating FaceTec SDK into a framework rather than an application directly? Are there any best practices for managing SDK initialization or view lifecycles within an iOS framework? Has anyone faced similar issues when integrating third-party SDKs into custom frameworks and how did they resolve them?

Hey all! During the migration of a production app to swift 6, I've encountered a problem: when hitting the UNUserNotificationCenter.current().requestAuthorization the app crashes. If I switch back to Language Version 5 the app works as expected. The offending code is defined here class AppDelegate: NSObject, UIApplicationDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -&gt; Bool { FirebaseApp.configure() FirebaseConfiguration.shared.setLoggerLevel(.min) UNUserNotificationCenter.current().delegate = self let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound] UNUserNotificationCenter.current().requestAuthorization(options: authOptions) { _, _ in } application.registerForRemoteNotifications() Messaging.messaging().delegate = self return true } } The error is depicted here: I have no idea how to fix this. Any help will be really appreciated thanks in advance

Since I updated my project I'm getting this error Stored property 'base' of 'Sendable'-conforming struct 'AnyShape' has non-sendable type '(CGRect) -> Path'; this is an error in the Swift 6 language mode I get this error at that struct, more specifically on the base variable public struct AnyShape: Shape { private var base: (CGRect) -> Path public init<S: Shape>(shape: S) { base = shape.path(in:) } public func path(in rect: CGRect) -> Path { base(rect) } } I have no idea how to solve this issue, I've been looking on the internet for same issues and get nothing yet

My project’s source code was building, running, and archiving successfully in Xcode 14.3. However, after upgrading to Xcode 15, I began encountering the error: “Command SwiftCompile failed with a nonzero exit code.” I couldn't resolve the issue, so I decided to continue using Xcode 14.3. Recently, I upgraded to macOS Sequoia and also updated to Xcode 16. Unfortunately, the same error persists in the latest Xcode: “Command SwiftCompile failed with a nonzero exit code.” The unfortunate part is that Xcode 14.3 no longer works after the macOS upgrade. Whenever I try to run the code, I get the following popup.
