Hey everyone, I have a problem with an app im creating. The code doesn't have any errors but the console has this that pops up: Snapshot request 0x1054191d0 complete with error: <NSError: 0x10541a970; domain: FBSSceneSnapshotErrorDomain; code: 4; "an unrelated condition or state was not satisfied"> { NSLocalizedDescription = an error occurred during a scene snapshotting operation; }

decidePolicyFor delegate method: import WebKit @objc extension DocumentationVC { func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) Being called just alright in swift 5 minimal concurrency. Raising concurrency to complete with swift 5 or swift 6. Changing the code to avoid warnings: @preconcurrency import WebKit @objc extension DocumentationVC { func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) { The delegate method is not being called. Changing back to swift 5 concurrency minimal - it is called. Looking at WKNavigationDelegate: WK_SWIFT_UI_ACTOR @protocol WKNavigationDelegate <NSObject> - (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(WK_SWIFT_UI_ACTOR void (^)(WKNavigationActionPolicy))decisionHandler WK_SWIFT_ASYNC(3); Changing the delegate method to: func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping @MainActor (WKNavigationActionPolicy) -> Void) { And it is called across swift 5 concurrency minimal to complete to swift 6. I thought, the meaning of @preconcurrency import WebKit was to keep the delegate without @MainActor before the (WKNavigationActionPolicy) still matching regardless the swift concurrency mode? My point is - this can introduce hidden breaking changes? I didn't see this documented anyhow at: https://www.swift.org/migration/documentation/migrationguide/. decidePolicyFor is an optional method - so if signature 'mismatches' - there will be no warning on not-implementing the delegate method. How do we catch or diagnose irregularities like this? Is it something @preconcurrency import WebKit should be ensuring and it is not? Is this delegate mismatch a bug on swift side or something we should be taking care of while migrating? If it is on us, how do we diagnose these potential mismatches?

我的应用是在mac intel时发生这个问题，从dump看程序一直卡在mmap_locked，不知要怎么修改 程序dump如下 amaran.txt

I have implemented the Game Center for authentication and saving player's game data. Both authentication and saving player's data works correctly all the time, but there is a problem with fetching and loading the data. The game works like this: At the startup, I start the authentication After the player successfully logs in, I start loading the player's data by calling fetchSavedGames method If a game data exists for the player, I receive a list of SavedGame object containing the player's data The problem is that after I uninstall the game and install it again, sometimes the SavedGame list is empty(step 3). But if I don't uninstall the game and reopen the game, this process works fine. Here's the complete code of Game Center implementation: class GameCenterHandler { public func signIn() { GKLocalPlayer.local.authenticateHandler = { viewController, error in if let viewController = viewController { viewController.present(viewController, animated: false) return } if error != nil { // Player could not be authenticated. // Disable Game Center in the game. return } // Auth successfull self.load(filename: "TestFileName") } } public func save(filename: String, data: String) { if GKLocalPlayer.local.isAuthenticated { GKLocalPlayer.local.saveGameData(Data(data.utf8), withName: filename) { savedGame, error in if savedGame != nil { // Data saved successfully } if error != nil { // Error in saving game data! } } } else { // Error in saving game data! User is not authenticated" } } public func load(filename: String) { if GKLocalPlayer.local.isAuthenticated { GKLocalPlayer.local.fetchSavedGames { games, error in if let game = games?.first(where: {$0.name == filename}){ game.loadData { data, error in if data != nil { // Data loaded successfully } if error != nil { // Error in loading game data! } } } else { // Error in loading game data! Filename not found } } } else { // Error in loading game data! User is not authenticated } } } I have also added Game Center and iCloud capabilities in xcode. Also in the iCloud section, I selected the iCloud Documents and added a container. I found a simillar question here but it doesn't make things clearer.

I have an xcode project which has both cpp and swift code. In one of my usecase I am passing primitive type variables from swift to cpp by reference( primitives types list here as per the new cpp-swift interop documentation) swift code: // primitive check code:Bool var x : Bool = true // When we are passing a variable as a Reference, we need to use explicitly use'&' student.PassBoolAsReferenceType (&x) // interop call to cpp code print (x) Cpp code: void Student::PassBoolAsReferenceType(bool &pValue) noexcept { std::cout << pValue << std::endl; pValue = false; } The above code fails during compilation with no clear error message "Command SwiftCompile failed with a nonzero exit code" However, all the other primitive types that I tested worked for the above code like Int, Float, Double etc. Only the Bool interop fails. Can someone explain why is it not possible for bool? I m using the new interop introduced in swift 5.9.

Is anyone have this problem on xcode 26 ?

Hi, I am exploring Closures and trying to understand how they works. Closure have a special key feature that they can capture the context of the variables/constants from surroundings, once captured we can still use them inside the closure even if the scope in which they are defined does not exist. I want to understand the lifecycle of captured variable/constant i.e., where are these captured variables stored and when these get created and destroyed. How is memory managed for captured variables or constants in a closure, depending on whether they are value types or reference types?

I can't find the arm_neon.h header file in macOS 15.6.1 This header file defines NEON intrinsics.

In scope of one of our project we've faced an issue with constant crashes when integrating C++ library in Swift code using Swift/C++ interoperability. Investigating the root causes of the issue we've discovered that with new version of Swift bug was introduced. Long story short: for strings bigger than 27 symbols memory is feed incorrectly that causes the crashes. By creating this post I wanted to draw community's attention to the problem and promote it to be solved quicker as for now it is not addressed.

Hello I want to implement customisation to swift argumentparser, Here are following changes want to do it in my cli changing default footer present in help command output currently help command output coming like this OVERVIEW: clisample USAGE: clisample <subcommand> OPTIONS: --version show the version. -h, --help show the help. SUBCOMMANDS: logs (default) Export logs for clisample processes. See 'clisample --help' for more information.' so instead of See 'clisample --help' for more information.' I want my own string For more details, run 'clisample help <subcommand>' customise error string getting from validation error Error: Missing value for '-t <time>' Help: -t <time> Time window (e.g. 10h, 30m, 2d). Usage: clisample logs --time <time> See 'clisample logs --help' for more information. so I want error output with example and customised footer, like this Error: Missing value for '-t <time>' Help: -t <time> Time window (e.g. 10h, 30m, 2d). Usage: clisample logs --time <time> Example: clisample logs -t 5m For more details, run 'clisample help <subcommand>' Is this changes possible from anyway?

I noticed that when I enter the fully immersive view and then click the X button below the window, the immersive space remains active, and the only way to dismiss it is to click the digital crown. On other apps (Disney+ for example), closing out of the main window while in immersive mode also closes out the immersive space. I tried applying an onDisappear modifier to the the Modules view with a dismissImmersiveSpace, but that doesn't appear to do anything. Any help would be appreciated.

I'm dealing with a strange bug where I am requesting read access for 'appleExerciseTime' and 'activitySummaryType', and despite enabling both in the permission sheet, they are being set to 'sharingDenied'. I'm writing a Swift Test for making sure permissions are being granted. @Test func PermissionsGranted() { try await self.manager.getPermissions() for type in await manager.allHealthTypes { let status = await manager.healthStore.authorizationStatus(for: type) #expect(status == .sharingAuthorized, "\(type) authorization status is \(status)") } } let healthTypesToShare: Set<HKSampleType> = [ HKQuantityType(.bodyMass), HKQuantityType(.bodyFatPercentage), HKQuantityType(.leanBodyMass), HKQuantityType(.activeEnergyBurned), HKQuantityType(.basalEnergyBurned), HKObjectType.workoutType() ] let allHealthTypes: Set<HKObjectType> = [ HKQuantityType(.bodyMass), HKQuantityType(.bodyFatPercentage), HKQuantityType(.leanBodyMass), HKQuantityType(.activeEnergyBurned), HKQuantityType(.basalEnergyBurned), HKQuantityType(.appleExerciseTime), HKObjectType.activitySummaryType() ] let healthStore = HKHealthStore() func getPermissions() async throws { try await healthStore.requestAuthorization(toShare: self.healthTypesToShare, read: self.allHealthTypes) } After 'getPermissions' runs, the permission sheet shows up on the Simulator, and I accept all. I've double checked that the failing permissions show up on the sheet and are enabled. Then the test fails with: Expectation failed: (status → HKAuthorizationStatus(rawValue: 1)) == (.sharingAuthorized → HKAuthorizationStatus(rawValue: 2)) HKActivitySummaryTypeIdentifier authorization status is HKAuthorizationStatus(rawValue: 1) Expectation failed: (status → HKAuthorizationStatus(rawValue: 1)) == (.sharingAuthorized → HKAuthorizationStatus(rawValue: 2)) HKActivitySummaryTypeIdentifier authorization status is HKAuthorizationStatus(rawValue: 1) With the rawValue of '1' being 'sharingDenied'. All other permissions are granted. Is there a workaround here, or something I'm potentially doing wrong?

No real intruduction for this, so I'll get to the point: All this code is on GitHub: https://github.com/the-trumpeter/Timetaber-for-iWatch But first, sorry; /* I got roasted, last time I posted; for not defining my stuff. This'll be different, but's gonna be rough; 'cuz there's lots and lots to get through: */ //this is 'Timetaber Watch App/Define (No expressions)/Courses_vDef.swift' on the GitHub: struct Course { let name: String let icon: String let room: String let colour: String let listName: String let listIcon: String let joke: String init(name: String, icon: String, room: String? = nil, colour: String, listName: String? = nil, listIcon: String? = nil, joke: String? = nil) { self.name = name self.icon = icon self.room = room ?? "None" self.colour = colour self.listName = listName ?? name self.listIcon = listIcon ?? (icon+".circle.fill") self.joke = joke ??

Hello, I am a software engineer student and I have recently been getting problems on my Mac regarding the C/C++ libraries. I have used my macbook for uni work for months, but around 3 or 4 months ago my macbook could not compile my work since it couldnt find the basic libraries I was using. For example, iostream. I have been using VSCode, and what it exactly says is "cannot open source file "iostream". Please run the 'Select IntelliSense Configuration...' command to locate your system headers." I have tried researching, changing the include path, even using chatgpt, and nothing. Is anyone having this same problem, or is able to help me? If any other information is needed, please let me know!

How can I calculate polynomial coefficients for Tone Curve points: // • Red channel: (0, 0), (60, 39), (128, 128), (255, 255) // • Green channel: (0, 0), (63, 50), (128, 128), (255, 255) // • Blue channel: (0, 0), (60, 47), (119, 119), (255, 255) CIFilter: func colorCrossPolynomial(inputImage: CIImage) -> CIImage? { let colorCrossPolynomial = CIFilter.colorCrossPolynomial() let redfloatArr: [CGFloat] = [1, 1, 1, 1, 0, 0, 0, 0, 0, 0] let greenfloatArr: [CGFloat] = [0, 1, 1, 0, 0, 0, 0, 0, 0, 1] let bluefloatArr: [CGFloat] = [0, 0, 1, 0, 0, 0, 0, 1, 1, 0] colorCrossPolynomial.inputImage = inputImage colorCrossPolynomial.blueCoefficients = CIVector(values: bluefloatArr, count: bluefloatArr.count) colorCrossPolynomial.redCoefficients = CIVector(values: redfloatArr, count: redfloatArr.count) colorCrossPolynomial.greenCoefficients = CIVector(values: greenfloatArr, count: greenfloatArr.count) return colorCrossPolynomial.outputImage }

With Swift being brought to new places, is anyone working on interoperability with PHP? I'd love to replace much of my PHP and Javascript web code with Swift (and ideally SwiftUI for UI design). Are there any projects/people working in this space?

Hello everyone. macOS, IOBluetooth framework. My goal is to create a temporary SDP service. According to the documentation, by default a temporary service is created (aka Persistent = NO), which is deleted after the application is closed. The documentation also mentions the IOBluetoothRemoveServiceWithRecordHandle function for forced removal of the service. This function is deprecated and is currently unavailable. I guesse that it has been replaced by the IOBluetoothSDPServiceRecord.removeServiceRecord method. The essence of the problem is that the server is not deleted either using removeServiceRecord or even after app closing. That is, if you create several services and try to delete them, they will remain alive. Only turning Bluetooth off and on in the OS helps. I tested all versions of macOS starting with Monteray. The same behavior. for (int i = 0; i < 10; i++) { service = [IOBluetoothSDPServiceRecord publishedServiceRecordWithDictionary:dictionary]; if (!service) { NSLog(@"Failed to create service"); } else { [service getRFCOMMChannelID:&channelID]; [service getServiceRecordHandle:&serverHandle]; NSLog(@"A new service has been created handle=%u, channelID=%hhu", serverHandle, channelID); if (service.removeServiceRecord != kIOReturnSuccess) { NSLog(@"Failed to delete service"); } //service.release; service = nil; } } Can someone confirm this behavior? And is there a solution? A minimal test example is available at the link
