A lot of apps use undocumented App-prefs URLs to help users get to the iOS Settings screen needed to set up the app. In iOS 18, it seems like these all stopped working. Here are the ones I currently use: App-prefs:MESSAGES - broken in iOS 18 Used for SMS Protection. App-prefs:Phone - broken in iOS 18 Used for Live Voicemail, Silence Unknown Callers, and SMS Reporting. Some but not most paths have specific documented replacements. E.g. for Call Blocking & Identification you can use CXCallDirectoryManager.sharedInstance.openSettings() and this still works in iOS 18. But I don't see any other direct replacements. Apple probably doesn't consider this a bug but I filed FB14378568 anyway. I consider this an accessibility issue because many older, inexperienced, or users with disabilities have trouble finding the right Settings screen based on a textual description alone.

I am creating an application that needs to connect to an Iot device, so i want to make a wifi hotspot with a custom SSID and password and WPA3. Could you please provide an example code in Objective-C to get started?

I've been teaching myself Objective-C and I wanted to start creating projects that don't use ARC to become better at memory management and learn how it all works. I've been attempting to build and run applications, but I'm not really sure where to start as modern iOS development is used with Swift and memory management is handled. Is there any way to create modern applications that use Objective-C, UIKit, and not use ARC?

I have a Safari extension that plays audio via the javascript AudioContext API. It was working fine under iOS 17 and is now broken under iOS 18. It does not play audio at all. I've tried in both the iOS 18 public beta and the iOS 18.1 developer beta. It is broken in both of them. I've also created Feedback item FB15170620 which has a url attached to a page I created which demonstrates the issue.

I'm building a SwiftUI app with a UITextView subclass, and it seems that the software keyboard doesn't trigger the pressesBegan or pressesEnded functions of UITextView. With a hardware keyboard, pressesBegan works as expected, allowing us to intercept key presses in our subclass. I can't find any documentation about this, or any other forum posts (here or on Stack Overflow) that talk about a discrepancy between software and hardware keyboard behaviors, and I can't believe this is an intended behavior. Our app is a SwiftUI app, in case that's relevant. Does anyone have any guidance? Is this a bug or am I not understanding this API? Any information or work arounds would be greatly appreciated. I've made a sample project that demonstrates this issue, which you can grab from GitHub at https://github.com/nyousefi/KeyPressSample. To see this in action, run the sample project and start pressing keys. The hardware keyboard will print the key press at the top of the screen (above the text view), while the software keyboard won't.

Hello. For the last few months I have been facing a situation for which I do not understand either the reason or the solution. Here is an example for the last few weeks: In App Store Connect it shows 214 crashes for the last week In Xcode it shows 56 crashes for the last 2 weeks without stack traces (NO_CRASH_STACK) In Firebase Crashlytics there is not a single crash. When I click "Show in Finder" it opens a folder with .xccrashpoint files. As far as I understood from the instructions on posting crash reports - this is not what is needed. Interesting point: it looks like the errors occur on iOS 15-16 devices. I have several questions: Why is the number of crashes in Xcode different from the number in App Store Connect? Where are the other crashes? How can I understand what the problem is if there are no stack traces in Xcode?

I am trying to add custom scheme (CFBundleURLSchemes) to my App Clip. I launch the app clip via TestFlight to cache it to the device then i try to access the custom scheme URL to launch App Clip but nothing happened. May I know if it is something I did wrongly or just App Clip does not support Custom Scheme?

アプリ内課金を実装しようとしていますが、サーバサイドのセキュリティに関してについて質問です。 StoreKit２を使えばアプリとApp Store Connect間のレシート検証は不要だが、 購入情報をサーバーで管理する場合は アプリからサーバーに購入情報を渡す際にレシート検証する必要があると考えるがその認識であっているか教えていただきたいです。

Hi there. How can I do for the title? URLRequest seems not to have property for protocols. NSURLSessionWebSocketTask seems to have either URLRequest or protocols, but have neither of them. What I want to do is setting both protocols and headers when using WebSocket. Should I use Network.framework instead?

Hello, I'm running into an issue while developing an iOS app that requires local network access. I’m using the latest MacBook Air M4 with macOS sequoia 15.5 and Xcode 16.1. In the iOS Simulator, my app fails to discover devices connected to the same local network. I’ve already added the necessary key to the Info.plist: NSLocalNetworkUsageDescription This app needs access to local network devices. When I run the app on a real device and M2 Chip Macbook's simulators, it works fine for local network permission as expected. However, in the M4 Chip Macbook's Simulator: The app can’t find any devices on the local network Bonjour/mDNS seems not to be working as well I’ve tried the following without success: Restarting Simulator and Mac Resetting network settings in Simulator Confirming app permissions under System Settings > Privacy & Security Has anyone else encountered this issue with the new Xcode/macOS combo? Is local network access just broken in the Simulator for now, or is there a workaround? Thanks in advance!

PDFKit PDFPage.characterBounds(at: Int) is returning incorrect coordinates with iOS 18 beta 4 and later / Xcode 16 beta 4. It worked fine in iOS 17 and earlier (after showing the same issue during the early iOS 17 beta cycle) It breaks critical functionality that my app relies on. I have filed feedback (FB14843671). So far no changes in the latest betas. iOS release date is approaching fast! Anybody having the same issue? Any workaround available?

I tested it on the app I work with and others I use and the notification message is not appearing when using sleep mode. Someone knows something about this, and if it is mapped for correction? Iphone: 13 mini IOS: 18.4.1

Hi, I'm adding tabs to the iOS version of my multiplatform app using TabView. I want the individual tabs to have names and icons. In iOS 17 and below, I have to do this using: tabContent().tabItem { Label(titleKey, systemImage: systemImage) } but this is deprecated, so in iOS 18 I would like to use the new version: Tab(titleKey, image: systemImage) { content() } It would be annoying to have to have the two cases for each individual tab, so I'm trying to abstract it into a custom SwiftUI view like this: var body: some View { if #available(iOS 18.0, *) { Tab(titleKey, image: systemImage) { content() } } else { content().tabItem { Label(titleKey, systemImage: systemImage) } } } There's a bit more to the custom view because I also have cases for iPad and macOS where I just have the views next to each other without tabs, but that's not really relevant to the question other than providing further motivation for abstracting this. However, with this code, I get the error: 'buildExpression' is unavailable: this expression does not conform to 'View' on the Tab line, because Tab isn't a view, and it can only be used directly inside a TabView. For now at least, I can just use tabItem on all iOS versions and it works, but I'd prefer not to in case it is removed some time soon. I do want to support iOS 17 because that's what my iPad runs. Is there any clean way to do this?

Hi, can someone explain me why there is so huge difference between download and install size? I get it that download is compressed but there difference is really huge.

Hi all, We're working on an iOS application and would like to improve our ability to diagnose failures - especially in scenarios where the app crashes before it can present any UI to the user. A few specific questions: In case of an exception or crash, is there a way to log the issue so the user (or our support team) can understand the cause of the failure? If the app crashes abruptly (e.g., due to a runtime exception or crash during launch), is there a recommended way to persist error information before the process terminates? Are there Apple-supported mechanisms (like crash reporting tools or APIs) we can integrate that would help us capture such issues? What’s the best practice for enabling support teams to assist users based on crash reports - especially for crashes that happen before any user interaction? Our goal is to make sure users aren't left in the dark if the app fails to start, and to allow us to deliver timely updates or support based on the cause of the crash. Thanks in advance for your guidance!

Hi all I'm reworking our app in SwiftUI. My ultimate goal is to access the NavigationPath from a child view which is used throughout different NavgationStacks. While searching for I came across different ways of achieving this. As I'm relatively new to SwiftUI it is hard to understand what the actual best practice seems to be. So for the use case. My app has a TabView and each Tab has its own NavigationStack which looks something like this struct TabNavigation: View { @State private var selectedProductType: StaticProductType = .all @StateObject private var appRouter = AppRouter() var body: some View { TabView(selection: $appRouter.selectedTab) { Overview(activeType: $selectedProductType) .tabItem { Label("Home", systemImage: "house") } .tag(Tab.home) AssortmentView(router: $appRouter.assortmentRouter, activeType: $selectedProductType) .tabItem { Label(String(localized: "assortment"), systemImage: "list.bullet") } .tag(Tab.assortment) } } The AssortmenView holds the NavigationStack and defines the routes. struct AssortmentView: View { @Binding var router: AssortmentRouter @Binding var activeType: StaticProductType var body: some View { NavigationStack(path: $router.navigationPath) { VStack { ProductTypeNavigation(activeType: $activeType) .padding(.top, 10) .padding(.horizontal, 10) Spacer() TabView(selection: $activeType) { ListNavigation(type: .all) .tag(StaticProductType.all) ListNavigation(type: .games) .tag(StaticProductType.games) ListNavigation(type: .digital) .tag(StaticProductType.digital) ListNavigation(type: .toys) .tag(StaticProductType.toys) ListNavigation(type: .movies) .tag(StaticProductType.movies) ListNavigation(type: .books) .tag(StaticProductType.books) } .tabViewStyle(PageTabViewStyle(indexDisplayMode: .never)) } .addToolbar() .navigationDestination(for: AssortmentRouter.Route.self) { route in switch route { case .overview(let type): OverviewTypeView(type: type) case .productDetail(let productId): ProductDetailView(productId: productId) .environmentObject(router) case .productList: ProductList() } } } } } Through my app I often use a view to displaying products. This view is reused over different NavigationStacks. struct ProductDetailView: View { var productId: Int @StateObject private var viewModel: ProductDetailViewModel = ProductDetailViewModel() @State private var showErrorAlert = false @EnvironmentObject var router: AssortmentRouter var body: some View { VStack { if !viewModel.isRefreshing { let product = viewModel.product VStack { Text("Product: \(product.title)") NavigationLink(destination: ProductDetailView(productId: Product.preview.productId)) { Text("Test") } } .navigationTitle(product.title) } else { ProgressView() } }.task { await loadProduct() } .alert("Error", isPresented: $showErrorAlert, presenting: viewModel.localizedError) { _ in Button("Try again") { Task { await loadProduct() } } Button("Go Back", role: .cancel) { // access navigationPath } } message: { errorMessage in Text(errorMessage) } } @MainActor private func loadProduct() async { await viewModel.loadProduct(productId: productId) showErrorAlert = viewModel.localizedError != nil } } In this example I created an AppRouter which holds all information for the routes and some functions to accessing the NavigationPath. class AppRouter: ObservableObject { var assortmentRouter = AssortmentRouter() var selectedTab: Tab = .home func navigateTo(tab: Tab) { selectedTab = tab } } class AssortmentRouter: ObservableObject { var navigationPath = NavigationPath() enum Route: Hashable { case overview(type: StaticProductType) case productList case productDetail(productId: Int) } func navigateTo(route: Route) { navigationPath.append(route) } } This works fine as it is. The pro of this solution is that I don't have to pass the NavigationPath down each subview to use it as I can define it as EnvrionmentObject. The problem with this though, I like to reuse ProductDetailView also in my other NavigationStack which won't have a router binding of type AssortmentRouter as you can imagine. To come back to my initial question, what would be the best way to design this? Passing down a NavigationPath Binding and using different typing for navigationDestinaion values Define a callback which is passed as function parameter to the detail view Using dismiss, but I read that this is can lead to weird behaviour and bugs Any other option? Maybe changing the app architecture to handle this a better way Apolgize the long post, but I would be really glad to get some feedback on this, so I can do it the right way. Thank you very much

What happens if Safari is uninstalled or disabled on iOS? Will SFafariviewcontroller still work? Kind regards

I am reaching out to seek clarification on the usage of exit(0) within an iOS application under specific circumstances, as I have not been able to find concrete guidance on this in the App Store Review Guidelines Context of Our Application: We are developing a mobile game using Cocos2d-JS (Cocos2d-x JavaScript bindings). The game is built in C++ with JavaScript used for game logic, and it runs on both Android and iOS. Occasionally, due to an unrecoverable fatal JavaScript error (e.g., corrupted state or unexpected runtime crash), the game’s screen goes completely black. When this occurs, the rendering engine halts, user interaction becomes impossible, and the app enters a non-functional state. From this point, the only way to return to a working state is to manually terminate and relaunch the app. We are exploring a user-friendly solution where, upon detecting such a critical failure, we present a native UIAlertController to the user explaining the issue and informing them that the app needs to restart. Upon confirmation (i.e., tapping “OK”), we call exit(0) to gracefully close the app, so the user can relaunch it in a working state. Our Question: Is it acceptable to use exit(0) in this very limited and clearly explained context? The intention is to improve the user experience during unrecoverable fatal states that cannot be handled through standard UI or engine resets. I understand that the use of exit(0) is generally discouraged, but in our case: The user explicitly initiates the exit via a native prompt. The app is not quitting on its own or in response to a policy violation. We are not using exit(0) to bypass App Review or circumvent system behavior. There is no mention in the App Review Guidelines explicitly stating whether or not exit(0) is disallowed in such edge cases. Please confirm whether this approach aligns with Apple's policies, or suggest an alternative method for cleanly handling such irrecoverable errors on iOS? Looking forward to your guidance.

When a new application runs on iOS 18.4 simulator and tries to access the Speech Framework, prompting a request for authorisation to use Speech Recognition, the application will crash if the user clicks allow.
