We are currently developing an enterprise iOS application and are in the process of implementing Data Leakage Protection (DLP) features. As part of this effort, we need to control the available actions and target applications presented within the UIActivityViewController. Specifically, we would like to programmatically filter or restrict certain activities and destination apps shown in the share sheet based on user-specific permissions. These permissions will be dynamically evaluated and updated at runtime. This type of functionality is supported by the Microsoft Intune SDK. However, our objective is to implement this behavior natively within our application without relying on any third-party libraries. Could you please advise on the recommended approach or available APIs to achieve this level of control over the UIActivityViewController?

I want to understand what the recommended way is for string interoperability between swift and c++. Below are the 3 ways to achieve it. Approach 2 is not allowed at work due to restrictions with using std libraries. Approach 1: In C++: char arr[] = "C++ String"; void * cppstring = arr; std::cout<<"before:"<<(char*)cppstring<<std::endl;           // C++ String // calling swift function and passing the void buffer to it, so that swift can update the buffer content Module1::SwiftClass:: ReceiveString (cppstring, length);   std::cout<<"after:"<<(char*)cppstring<<std::endl;             // SwiftStr      In Swift: func ReceiveString (pBuffer : UnsafeMutableRawPointer , pSize : UInt ) -> Void { // to convert cpp-str to swift-str: let swiftStr = String (cString: pBuffer.assumingMemoryBound(to: Int8.self)); print("pBuffer content: \(bufferAsString)"); // to modify cpp-str without converting: let swiftstr:String = "SwiftStr"      _ =  swiftstr.withCString { (cString: UnsafePointer<Int8>) in pBuffer.initializeMemory(as: Int8.self, from: cString, count: swiftstr.count+1) } }  Approach 2:  The ‘String’ type returned from a swift function is received as ‘swift::String’ type in cpp. This is implicitly casted to std::string type. The std::string has the method available to convert it to char *. void TWCppClass::StringConversion () {     // GetSwiftString() is a swift call that returns swift::String which can be received in std::string type     std::string stdstr = Module1::SwiftClass::GetSwiftString ();     char * cstr = stdstr.data ();     const char * conststr= stdstr.c_str (); }    Approach 3: The swift::String type that is obtained from a swift function can be received in char * by directly casting the address of the swift::String. We cannot directly receive a swift::String into a char *. void TWCppClass::StringConversion () {    // GetSwiftString() is a swift call that returns swift::String    swift::String swiftstr = Module1::SwiftClass::GetSwiftString ();    // obtaining the address of swift string and casting it into char *    char * cstr = (char*)&swiftstr; }

We are building a hybrid iOS app using Angular (web) rendered inside a WKWebView, hosted by a native Swift app. Communication between the Angular UI and native Swift code is done using WKScriptMessageHandler. The app mostly works without issues, but in rare edge cases, we’re seeing crashes on the main thread, and the crash is reported in Firebase Crashlytics. The root cause appears related to CFRelease and WKScriptMessageHandler. Here’s the relevant crash stack: Crashed: com.apple.main-thread 0 CoreFoundation 0xbfac CFRelease + 44 1 CoreFoundation 0xa734 __CFURLDeallocate + 128 2 CoreFoundation 0x730c _CFRelease + 292 3 libobjc.A.dylib 0x4e28 AutoreleasePoolPage::releaseUntil(objc_object**) + 204 4 libobjc.A.dylib 0x4cbc objc_autoreleasePoolPop + 260 5 WebKit 0x99f194 WebKit::WebUserContentControllerProxy::didPostMessage(WTF::ObjectIdentifierGeneric<WebKit::WebPageProxyIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, WebKit::FrameInfoData&&, WTF::ObjectIdentifierGeneric<WebKit::ScriptMessageHandlerIdentifierType, WTF::ObjectIdentifierMainThreadAccessTraits<unsigned long long>, unsigned long long>, std::__1::span<unsigned char const, 18446744073709551615ul>, WTF::CompletionHandler<void (std::__1::span<unsigned char const, 18446744073709551615ul>, WTF::String const&)>&&) + 680 6 WebKit 0x1b358 WebKit::WebUserContentControllerProxy::didReceiveMessage(IPC::Connection&, IPC::Decoder&) + 392 7 WebKit 0xe86b0 IPC::MessageReceiverMap::dispatchMessage(IPC::Connection&, IPC::Decoder&) + 272 8 WebKit 0x23c0c WebKit::WebProcessProxy::didReceiveMessage(IPC::Connection&, IPC::Decoder&) + 44 9 WebKit 0xe3f054 IPC::Connection::dispatchMessage(WTF::UniqueRef<IPC::Decoder>) + 252 10 WebKit 0x332d4 IPC::Connection::dispatchIncomingMessages() + 744 11 JavaScriptCore 0x58a7c WTF::RunLoop::performWork() + 204 12 JavaScriptCore 0x599a4 WTF::RunLoop::performWork(void*) + 36 13 CoreFoundation 0x56328 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 14 CoreFoundation 0x562bc __CFRunLoopDoSource0 + 176 15 CoreFoundation 0x53dc0 __CFRunLoopDoSources0 + 244 16 CoreFoundation 0x52fbc __CFRunLoopRun + 840 17 CoreFoundation 0x52830 CFRunLoopRunSpecific + 588 18 GraphicsServices 0x11c4 GSEventRunModal + 164 19 UIKitCore 0x3d2eb0 -[UIApplication _run] + 816 20 UIKitCore 0x4815b4 UIApplicationMain + 340 21 APP1 0xa2f80 main + 21 (AppDelegate.swift:21) 22 ??? 0x1c234eec8 (シンボルが不足しています) Steps: WebView: WKWebView Message passing: WKScriptMessageHandler → passing data from Angular → Swift WKWebView is long-lived and reused Native is using WKUserContentController.add(_:name:) to register handlers Crashes are intermittent (hard to reproduce), but often follow: Screen sleep/wake Push notification open Angular calling native immediately after resume Questions: Has anyone seen this specific crash pattern involving CFRelease and WKScriptMessageHandler?

I'm soliciting you because I'm having a problem using the 3D short cut for my ios application in uikit in the AppDelegate file but it's impossible to redirect the route when the user has completely killed the application.

In SwiftUI sliders now have tick marks by default on iOS26, how do you turn them off or hide them? This WWDC talk had some sample code on how to set the tick marks but it doesn't compile for me: https://developer.apple.com/videos/play/wwdc2025/323/ I don't see any available methods or initializers to turn them off.

This may seem really basic, but I'm not using the screen designer, I'm doing this old school (programmatically). I think I'm using Swift 5 (not actually sure). This image may help. So I created my own UIImageView class called GenericImage class GenericImage: UIImageView, @unchecked Sendable { ... } I create the GenericImage class and add it to the View Controller. Then I load the image and set some positioning within my GenericImage class let imageView = GenericImage(frame: CGRect.zero) self.view.addSubview(imageView) imageView.processResponse(componentDictionary ) In the GenericImage class I load the image and set some constraints. self.imageFromURL(urlString: imageUrl) self.translatesAutoresizingMaskIntoConstraints = false self.contentMode = .scaleAspectFit self.widthAnchor.constraint(equalToConstant: 100.0).isActive = true self.heightAnchor.constraint(equalToConstant: 100.0).isActive = true self.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true self.topAnchor.constraint(equalTo: self.centerYAnchor).isActive = true The image is displayed at the top left of the screen. I'm guessing that the code I have written should center the image on the screen. However, while I would like to know how to center the image, I also want to be able to position it at a specific place on the screen, using points (or pixels). Any suggestions?

Hello, I'm adding a CollisionComponent to an entity in RealityView. CollisionComponent requires that a Mesh must be provided as a reference for collision detection. However, in order to achieve more accurate detection, I hope that this Mesh resource is a geometric shape of a USDZ model. Is there any way to make it happen? Thank you!

I have attached two images of two screens below. In one screen, bar button are enclosed within separate, distinct, rounded-rectangle 'liquid glass' capsules. In other screen, bar buttons are enclosed within separate, distinct, rounded-rectangle "liquid glass" capsules. They are not visually merged into one larger capsule. Both are having same code. But why it is not same ?

Hello everyone. I'm getting an error in my code and I don't know why. Can someone explain it to me? import SwiftUI struct ContentView: View{ var body: some View{ VStack { Button {} label: { Text("Click Me") } .buttonStyle(.glass) .frame(width: 200, height: 200) } } } The error is as follows: Reference to member 'glass' cannot be resolved without a contextual type Thanks for your help

Hi team, while i am using below code, i am getting two searchBar at top & bottom. Kindly refer below code & attached image Code: override func viewDidLoad() { super.viewDidLoad() title = "Test Data" setupSearchData() DispatchQueue.main.asyncAfter(deadline: .now() + 2) { self.setupSearchData() } } func setupSearchData() { navigationController?.navigationBar.prefersLargeTitles = false let searchController = UISearchController(searchResultsController: nil) navigationItem.searchController = searchController } It is working fine for other iOS versions. In my real useCase, i will refresh screen after API completed, then this issue occurred in my app.

Hello everyone, 👋🏼🤠 I've been struggling with a persistent issue for several weeks and would greatly appreciate any insights or suggestions from the community. ❗️Problem Summary We are sending JSON requests (~100 KB in size) via URLSession from a Swift app running on Windows. These requests consistently time out after a while. Specifically, we receive the following error: Error Domain=NSURLErrorDomain Code=-1001 "(null)" This only occurs on Windows – under macOS and Linux, the same requests work perfectly. 🔍 Details The server responds in under 5 seconds, and we have verified that the backend (a Vapor app in Kubernetes) is definitely not the bottleneck. The request always hits the timeout interval, no matter how high we configure it: 60, 120, 300, 600 seconds – the error remains the same. (timeoutForRequest) The request flow: Swift App (Windows) ---> HTTPS ---> Load Balancer (NGINX) ---> HTTP ---> Ingress Controller ---> Vapor App (Kubernetes) On the load balancer we see this error: client prematurely closed connection, so upstream connection is closed too (104: Connection reset by peer) The Ingress Controller never receives the complete body in these error cases. The content length set by the Swift app exceeds the data actually received. We disabled request buffering in the Ingress Controller, but the issue persists. We even tested a setup where we inserted a Caddy server in between to strip away TLS. The Swift app sent unencrypted HTTP requests to Caddy, which then forwarded them. This slightly improved stability but did not solve the issue. 🧪 Additional Notes The URLSession is configured in an actor, with a nonisolated URLSession instance: actor DataConnectActor { nonisolated let session : URLSession = URLSession(configuration: { let urlSessionConfiguration : URLSessionConfiguration = URLSessionConfiguration.default urlSessionConfiguration.httpMaximumConnectionsPerHost = ProcessInfo.processInfo.environment["DATACONNECT_MAX_CONNECTIONS"]?.asInt() ?? 16 urlSessionConfiguration.timeoutIntervalForRequest = TimeInterval(ProcessInfo.processInfo.environment["DATACONNECT_REQUEST_TIMEOUT"]?.asInt() ?? 120) urlSessionConfiguration.timeoutIntervalForResource = TimeInterval(ProcessInfo.processInfo.environment["DATACONNECT_RESSOURCE_TIMEOUT"]?.asInt() ?? 300) urlSessionConfiguration.httpAdditionalHeaders = ["User-Agent": "DataConnect Agent (\(Environment.version))"] return urlSessionConfiguration }()) public internal(set) var accessToken: UUID? = nil ... } Requests are sent via a TaskGroup, limited to 5 concurrent tasks. The more concurrent tasks we allow, the faster the timeout occurs. We already increased the number of ephemeral ports in Windows. This made things slightly better, but the problem remains. Using URLSessionDebugLibcurl=1 doesn't reveal any obvious issue related to libcurl. We have also implemented a retry mechanism, but all retries also time out. 🔧 Request Flow (Code Snippet Summary) let data = try JSONEncoder().encode(entries) var request = URLRequest(url: url) request.httpMethod = "POST" request.httpBody = data request.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization") request.setValue("application/json; charset=UTF-8", forHTTPHeaderField: "Content-Type") // additional headers... let (responseData, response) = try await urlSession.data(for: request) ✅ What We’ve Tried Tested with and without TLS Increased timeout and connection settings Disabled buffering on Ingress Increased ephemeral ports on Windows Limited concurrent requests Used URLSessionDebugLibcurl=1 We don't know how we can look any further here. Thank you in advance for any guidance!

I have a mac (M4, MacBook Pro) running Tahoe 26.0 beta. I am running Xcode beta. I can run code that uses the LLM in a #Preview { }. But when I try to run the same code in the simulator, I get the 'device not ready' error and I see the following in the Settings app. Is there anything I can do to get the simulator to past this point and allowing me to test on it with Apple's LLM?

Hello there! I've been struggline with this thing for a two days now, and seems like it's a bug in SwiftUI. Navigation title is jumping on top of the ScrollView's content when switching tabs in TabView. Steps to reproduce: Scroll one tab to the bottom so that the large title is hidden and the floating toolbar appears. Go to another tab in the tab bar. Go back to the initial tab (it is still scrolled), and press the current tab button again to scroll to the top. The navigation title will glitch and be on top of the content. The animation fixes if you scroll again manually. Video: https://share.cleanshot.com/PFCSKMlH Code (simplified): import SwiftData import SwiftUI @main struct MyApp: App { var body: some Scene { WindowGroup { TabsContentView() } } } // ... struct TabsContentView: View { enum Tab { case library, profile } @State private var selectedTab: Tab = .library var body: some View { TabView(selection: $selectedTab) { NavigationStack { YourLibraryList() .navigationTitle("Your Library") } .tabItem { Label("Library", systemImage: "tray.fill") } .tag(Tab.library) NavigationStack { VStack { Spacer() Text("Profile") .font(.largeTitle) .foregroundColor(Color.theme.text) Text("Manage your account and preferences here") .font(.body) .foregroundColor(Color.theme.mutedForeground) .multilineTextAlignment(.center) .padding(.horizontal) Spacer() } .navigationTitle("Explore") } .tabItem { Label("Profile", systemImage: "person.fill") } .tag(Tab.profile) } .toolbarBackground(.ultraThinMaterial, for: .tabBar) .toolbarBackground(.visible, for: .tabBar) } } // ... struct YourLibraryList: View { var body: some View { ScrollView { VStack(spacing: 12) { ForEach(1 ... 20, id: \.self) { number in RoundedRectangle(cornerRadius: 12) .fill(Color.blue.opacity(0.1)) .stroke(Color.blue, lineWidth: 1) .frame(height: 60) .overlay( Text("\(number)") .font(.title2) .fontWeight(.semibold) .foregroundColor(.blue) ) } } .padding(.horizontal) } } }

Currently, I’m working on developing a small macOS utility tool for my photography. In my camera, I have a digital zoom feature. I prefer using this feature when I shoot both JPEG and DNG files. While the JPEG is already cropped to the desired format, the DNG file contains metadata (DefaultUserCrop: 0.22, 0.22, 0.78, 0.78). For instance, when I open that DNG file in Lightroom, it pre-crops the image non-destructively. However, I prefer using Pixelmator Pro for editing. Unfortunately, Pixelmator Pro doesn’t have this feature. So, I thought I could create an app that allows me to pre-crop the image for editing in Pixelmator Pro afterward. Does someone have a better idea or some hints on how I could solve it?

I'm working with images selected from the iOS Photos app using PHPickerViewController. Some images appear as HEIF in the Photos info panel — which I understand are stored in the HEIC format, i.e., HEIF containers with HEVC-compressed images, commonly used on iOS when "High Efficiency" is enabled. To convert these images to JPEG, I'm using the standard UIKit approach: if let image = UIImage(data: heicData) { let jpegData = image.jpegData(compressionQuality: 1.0) } However, I’ve noticed that this conversion often increases the image size significantly: Original HEIC/HEIF: ~3 MB Converted JPEG (quality: 1.0): ~8–12 MB There’s no resolution change or image editing — it’s just a direct conversion. I understand that HEIC is more efficient than JPEG, but the increase in file size feels disproportionate. Is this kind of jump expected, or are there any recommended workarounds to avoid it?

I am in the process of writing a macOS app using NSFileProviderExtension so that I can map my customer's data in Finder. I am in the process of building it out, I had initially started in Obj-C and then after the advice of folks here (https://developer.apple.com/forums//thread/793272?answerId=849339022&amp;page=1#849752022) I have switched to Swift as the NSReplicatedFileProvider is not available in Obj-C. I have done the main app and also started plugging away with the FileProviderExtension. To verify that I have properly setup, I create a static list of files in the FileProviderExtension enumerate so I can see it work in Finder. I build the app and it works as expected and I see it mounted in Finder and I see the static list of files. But what I don't see is any debug statements in the app, none of those message show up in the logs. I am baffled by this. I check the log stream to see what the process prints out and I know it is logging everything else eg: 2025-07-18 11:32:05.772364-0700 0x19ea3f9 Activity 0x1172100 63622 0 DriveFileProviderExtension: (libsystem_secinit.dylib) AppSandbox 2025-07-18 11:32:05.794609-0700 0x19ea3f9 Activity 0x1172101 63622 0 DriveFileProviderExtension: (libsystem_info.dylib) Retrieve User by ID 2025-07-18 11:32:05.800179-0700 0x19ea3f9 Default 0x0 63622 0 DriveFileProviderExtension: (ExtensionFoundation) [com.apple.extensionkit:default] Extension `/Users/radwar/Library/Developer/Xcode/DerivedData/Drive-fxfhbjutfvumoabnnfmxxstpifha/Build/Products/Debug/Drive.app/Contents/PlugIns/DriveFileProviderExtension.appex/Contents/MacOS/DriveFileProviderExtension` of type: `1` launched. 2025-07-18 11:32:05.801453-0700 0x19ea3f9 Default 0x0 63622 0 DriveFileProviderExtension: (RunningBoardServices) [com.apple.runningboard:connection] Initializing connection 2025-07-18 11:32:05.803083-0700 0x19ea3f9 Default 0x0 63622 0 DriveFileProviderExtension: (RunningBoardServices) [com.apple.runningboard:process] Removing all cached process handles 2025-07-18 11:32:05.803231-0700 0x19ea613 Default 0x0 63622 0 DriveFileProviderExtension: (RunningBoardServices) [com.apple.runningboard:connection] Sending handshake request attempt #1 to server 2025-07-18 11:32:05.803414-0700 0x19ea613 Default 0x0 63622 0 DriveFileProviderExtension: (RunningBoardServices) [com.apple.runningboard:connection] Creating connection to com.apple.runningboard 2025-07-18 11:32:05.803459-0700 0x19ea613 Default 0x0 63622 0 DriveFileProviderExtension: (libxpc.dylib) [com.apple.xpc:connection] [0x12f106e10] activating connection: mach=true listener=false peer=false name=com.apple.runningboard 2025-07-18 11:32:05.805893-0700 0x19ea613 Default 0x0 63622 0 DriveFileProviderExtension: (RunningBoardServices) [com.apple.runningboard:connection] Handshake succeeded 2025-07-18 11:32:05.805955-0700 0x19ea613 Default 0x0 63622 0 DriveFileProviderExtension: (RunningBoardServices) [com.apple.runningboard:connection] Identity resolved as xpcservice&lt;clio.Drive.DriveFileProviderExtension([osservice&lt;com.apple.FileProvider(501)&gt;:990])(501)&gt;{vt hash: 247410607}[uuid:454E32DB-3FB4-4DC6-9C05-F4B2F97333E0]{persona:9EF54117-4998-4D72-83C4-F12587C95FBA} but none of my print lines are being printed.

A method in my app now requires the override keyword when compiling with Xcode 26 beta / iOS 26 SDK, but if I add it, the current official Xcode 16.4 (iOS 18 SDK) throws a compile error. It's about 'toggleSidebar(_:)' in UIViewController. The problem is: Apple expects our apps to be ready for iOS 26 launch this fall, so I need to be actively developing and testing in the Xcode 26 beta now. At the same time, I still need to submit updates to the App Store using the current official Xcode 16.4 until iOS 26 officially launches. I'm using a single .xcodeproj file and can't keep manually adding/removing -DIOS_SDK_26_OR_LATER in Build Settings multiple times a day. How to fix it and why isn't there a straightforward #if sdk(>=26.0) type of check for compile-time in Swift? It's really frustrating to manage this override conflict.

This happens when trying to connect to my development web server. The app works fine when connecting to my production server. The production server has a certificate purchased from a CA. My development web server has a locally generated certificate (from mkcert). I have dragged and dropped the rootCA.pem onto the Simulator, although it doesn't indicate it has been loaded the certificate does appear in the Settings app and is checked to be trusted. I have enabled "App Sandbox" and "Outgoing connections (Client)". I have tested the URL from my local browser which is working fine. What am I missing?
