Some Macs recently received a macOS system update which disabled the simulator runtimes used by Xcode 15, including the simulators for iOS, tvOS, watchOS, and visionOS. If your Mac received this update, you will receive the following error message and will be unable to use the simulator: The com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime is not available. Domain: com.apple.CoreSimulator.SimError Code: 401 Failure Reason: runtime profile not found using "System" match policy Recovery Suggestion: Download the com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime from the Xcode To resume using the simulator, please reboot your Mac. After rebooting, check Xcode Preferences → Platforms to ensure that the simulator runtime you would like to use is still installed. If it is missing, use the Get button to download it again. The Xcode 15.3 Release Notes are also updated with this information.

Hello, all, I'm new to iOS development and working on a project with the following setup: Architecture: Windows PC running Ubuntu (WSL) hosting a WebSocket Server with self-signed SSL Python GUI application as a client to control iOS app iOS app as another client on physical iPhone Server running on wss://***.***.***.1:8001 (this is the mobile hotspot IP from Windows PC which the iPhone is needed to connect to as well) Current Status: ✓ Server successfully created and running ✓ Python GUI connects and functions properly ✓ iOS app initially connects and communicates for 30 seconds ✗ iOS connection times out after 30 seconds ✗ Map updates from GUI don't sync to iOS app Error Message in Xcode terminal: WebSocket: Received text message 2024-11-25 15:49:03.678384-0800 iVEERS[1465:454666] Task <CD21B8AD-86D9-4984-8C48-8665CD069CC6>.<1> finished with error [-1001] Error Domain=NSURLErrorDomain Code=-1001 "The request timed out."

Please let me know if additional code snippets would help on what I currently have.

If I define some values in an .xcconfig then I can use those to supply a value to an element within Info.plist, but if I try to do the same for a .plist with any other name then it doesn't work. Is this some sort of hard-coded constraint? (I can't move the elements out of the custom .plist into Info.plist as its being read by a 3rd party framework)

Hello everyone, We have an iOS XCFramework that we distribute to our clients, and we're exploring ways to enhance its security. Specifically, we’d like to isolate the most sensitive code by running it in a separate process, making it harder to tamper with. During our research, we considered using XPC for iOS but found its functionality to be quite limited. We also explored App Extensions, but unfortunately, they cannot be integrated into an XCFramework. This leads us to the question: Is it possible to spawn a new process to run in parallel with the main one in iOS? If so, could you provide guidance or suggest alternative approaches to achieve this within the constraints of iOS development? Thank you in advance for your insights and advice! Best regards, Stoyan

Title: Unable to Access Microphone in Control Center Widget – Is It Possible? Hello everyone, I'm attempting to create a widget in the Control Center that accesses the microphone, similar to how Shazam does it. However, I'm running into an issue where the widget always prints "Microphone permission denied." It's worth mentioning that microphone access works fine when I'm using the app itself. Here's the code I'm using in the widget: swift Copy code func startRecording() async { logger.info("Starting recording...") print("Starting recording...") recognizedText = "" isFinishingRecognition = false // First, check speech recognition authorization let speechAuthStatus = await withCheckedContinuation { continuation in SFSpeechRecognizer.requestAuthorization { status in continuation.resume(returning: status) } } guard speechAuthStatus == .authorized else { logger.error("Speech recognition not authorized") return } // Then, request microphone permission using our manager let micPermission = await AudioSessionManager.shared.requestMicrophonePermission() guard micPermission else { logger.error("Microphone permission denied") print("Microphone permission denied") return } // Continue with recording... } Issues: The code consistently prints "Microphone permission denied" when run from the widget. Microphone access works without issues when the same code is executed from within the app. Questions: Is it possible for a Control Center widget to access the microphone? If yes, what might be causing the "Microphone permission denied" error in the widget? Are there additional permissions or configurations required to enable microphone access in a widget? Any insights or suggestions would be greatly appreciated! Thank you.

I filled in some information when publishing the application and felt that the icon was not good enough. I made another one and used this new icon in XCode. After running it on iPhone, the icon changed, but there was no change in the submission section. Now the application is in the "ready to submit" stage and I don't know how to change it to the new icon. Can anyone give me some guidance? Thank you!

Dear Support Team, I constantly get a 401 unauthorised error, when I try to add my Developer account in Xcode while running a virutalised macOS using https://developer.apple.com/documentation/virtualization. So I can't use signing, entitlements, etc when building within a virutalised macOS. The error shown is below: There was a failure decoding response: (HTTP 401, 60 bytes) The data couldn’t be read because it isn’t in the correct format. I've found probably the same issue here https://developer.apple.com/forums/thread/759877 Unfortunately, I can't find any updates. Are you aware of this problem? Are there any planned fixes in upcoming macOS updates? 15.0 (24A335) Version 16.1 (16B40) Apple M1 Pro, 16 GB Ram Best regards, Evgenii

In Xcode's (version 16.1) "Devices and Simulators" window pressing the device's context menu item "Show Provisioning Profiles..." does nothing: no new window, no message, nothing. How can I fix this?

Hi! I'm trying to create a target application that depends on multiple targets that all use the same Swift package that has xcframework binaryTarget. Each component can be successfully assembled individually, but when I try to create a core application that depends on these components, I get an error message on Prepare build stage: Multiple commands produce '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/Build/Products/Debug/Frameworks/<FW_NAME>.framework/Versions/A' Target '<COMPONENT1>' has copy command from '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/SourcePackages/artifacts/.../<FW_NAME>/<FW_NAME>.xcframework/macos-arm64_x86_64/<FW_NAME>.framework' to '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/Build/Products/Debug/Frameworks/<FW_NAME>.framework' Target '<COMPONENT2>' has copy command from '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/SourcePackages/artifacts/.../<FW_NAME>/<FW_NAME>.xcframework/macos-arm64_x86_64/<FW_NAME>.framework' to '/Users/<USER>/Library/Developer/Xcode/DerivedData/<PROJECT_ID>/Build/Products/Debug/Frameworks/<FW_NAME>.framework' – where <FW_NAME> is a name of the xcframework which is the binaryTarget in the Swift package. Could someone please explain to me if it is even possible to use xcframeworks packaged in Swift packages in such cases, and if so, how to do it correctly?

I'm on an Intel-based Mac running macOS Sonoma 14.7.1 (23H222) and Xcode Version 16.1 (16B40). I've created a local StoreKit Configuration File that does not synchronise with App Store Connect and selected it in the Scheme. I have some products that are consumable in-app purchase and it loads fine as expected when I run the app and I am able to make transactions. It also show up in the Transaction Manager. After a little while, working on the app, re-running it several times, it stops working. The products do not load the metadata from the StoreKit configuration file. I also get this error in the console: Error enumerating unfinished transactions for first transaction listener: Error Domain=NSURLErrorDomain Code=-1003 "A server with the specified hostname could not be found."

Relaunching Xcode doesn't help and neither does deleting Project Build Data and Indexes.

I am using Xcode16, old React Native. I don't know why CLANG_CXX_LANGUAGE_STANDARD in Pods is gnu++14 when I pod install locally, but gnu++20 when I pod install with CircleCI

Why is gnu++14 specified locally and gnu++20 specified in CI?

Hi, Our team uses Xcode Cloud to run unit tests, and since around November, we’ve been frequently experiencing timeouts with the following type of process: @Test func hogeTest() async { // do something hoge.do() // wait until done await wait(condition: { hoge.isDone }) // test result #expect(hoge.isSucceeded) } private func wait(condition: () async -> Bool, timeout: TimeInterval = 0.5, pollingInterval: TimeInterval = 0.01) async throws { let deadline = Date().addingTimeInterval(timeout) while Date() < deadline { if await condition() { return } try await Task.sleep(nanoseconds: UInt64(round(pollingInterval * TimeInterval(NSEC_PER_SEC)))) } Issue.record("timeout") } Although sleep is supposed to wait for only a few milliseconds, there are cases where it takes more than 10 seconds, leading to a timeout. What could be causing this instability in the sleep duration? Additionally, if there are other recommended ways to implement polling and waiting in Swift Testing, I would appreciate it if you could share them. A feedback report (FB15899163) has already been submitted. Best regards,

Our use case is that we need to run a CLI script (on Mac) to set up backend configuration before each test case (UI test on real iOS device). The setup logic is test specific, so using pre-build scripts is not an option. Is this support in any way or what are best practices around such a setup? Ideally, we would still be able to execute the tests from within Xcode.

We've encountered a critical issue with the new linker of CLT16 (version 16.1.0.0.1.1729049160) that prevents proper initialization of BLOCK DATA. BLOCK DATA are used to initialize global variables in our Fortran code, and its failure to initialize those variables leads to a program crash. This affects our community of more that thousand scientists worldwide. The current workaround is using the -ld_classic linker option. However, this option is deprecated and will be removed in a future release, as described in the Xcode release note. I've attached a minimal example that reproduces the problem using GNU gfortran with the following instructions (the attached main.f.txt and bd.f.txt need to be rename to main.f and bd.f, respectively): gfortran -c bd.f gfortran -c main.f ar rv libtest.a bd.o main.o gfortran -ld_classic -o good.x -L. libtest.a gfortran -o bad.x -L. libtest.a Running the two programs, one can see that the BLOCK DATA are not initialised without the option ld_classic, $ > ./good.x 3.7273802569289098 2.8083922366048202 $ > ./bad.x 0.0000000000000000 0.0000000000000000 We kindly request your attention to this matter and a prompt solution or alternative workaround. Best regards main.f.txt bd.f.txt part.txt

Hi, so i'm trying to use Activity.update but XCode throws an error if I don't use the ios 16 syntax, only to throw a warning that it's deprecated if I do. Screenshots below. Should I bug report or is there a known workaround?

Hi everyone, I'm working on a macOS authorization plugin (NameAndPassword) to enable users to log into their system using only MFA, effectively making it passwordless. To achieve this, I'm attempting to store the user's password securely in the Keychain so it can be used when necessary without user input. However, when I attempt to store the password, I encounter error code -25308. Below is the code I'm using to save the password to the Keychain: objc code (void)storePasswordInKeychain:(NSString *)password forAccount:(NSString *)accountName { NSData *passwordData = [password dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary *query = @{ (__bridge id)kSecClass: (__bridge id)kSecClassGenericPassword, (__bridge id)kSecAttrService: @"com.miniOrange.nameandpassword", (__bridge id)kSecAttrAccount: accountName, (__bridge id)kSecValueData: passwordData, (__bridge id)kSecAttrAccessible: (__bridge id)kSecAttrAccessibleAfterFirstUnlock }; // Delete any existing password for the account OSStatus deleteStatus = SecItemDelete((__bridge CFDictionaryRef)query); if (deleteStatus == errSecSuccess || deleteStatus == errSecItemNotFound) { [Logger debug:@"Old password entry deleted or not found."]; } else { [Logger error:@"Failed to delete existing password: %d", (int)deleteStatus]; } // Add the new password OSStatus addStatus = SecItemAdd((__bridge CFDictionaryRef)query, NULL); if (addStatus == errSecSuccess) { [Logger debug:@"Password successfully saved to the Keychain."]; } else { [Logger error:@"Failed to save password: %d", (int)addStatus]; } } Any insights or suggestions would be greatly appreciated!

Hi team, We're using CocoaPods in our project and we noticed the compiler fails to build certain targets saying it's "Missing required module 'x'" when trying to build them in Swift 6: We realized the modules the compiler is complaining about are pod dependencies required by the other target dependencies, and that this error will only appear when building with Swift 6 unless such dependencies are described on the Podfile as direct dependencies of the target, or we include them in the framework search paths. For example, the error in the image above will show if module 'X' import 'Y' and 'Y' imports 'CocoaLumberJack' and we don't specify a direct dependency between 'X' and 'CocoaLumberJack'. Regardless of the fact that we can manually add the missing module location to the target search paths, we'd like to understand why we're facing this issue in the first place, what changed between Swift 5 and Swift 6 that's requiring us now to explicitly describe these dependencies. I'd appreciate if someone could tell us more about this. We're particularly interested on knowing if this is an intentional change and how to handle it properly. Thanks

Hi the app crashes with message: **thunk for @escaping @callee_guaranteed (@guaranteed NSURLSessionTask) -> () + 48 (:0) ** and I am unable to understand what it means or why is it happening. Want to understand the reason for the message. Thank you.

The app gets stuck after login on an iOS 18 device. It works in Xcode, but the simulator shows the following console error: IntegrationApp(769,0x1f0094c00) malloc: xzm: failed to initialize deferred reclamation buffer (46).

Hi, I tried to make a new branch of my project and upon doing so, all of my old files disappeared. They are no longer in my folder directory or available in Xcode. Please let me know if there is any way to recover these files. I don't see the files in my trash either.
