If I have two iOS apps, with bundle ids com.mycompany.A and com.mycompany.B, and they both have the shared group id of group.com.mycompany.B, then they can read/write data to same file (in shared defaults or, for example, a Realm database saved to the same shared group location). What I have noticed is that if both apps get installed and some data X written to shared defaults (but data which isn't accessed by both apps i.e. if only app A uses this data), then if app A is deleted and reinstalled then X is not deleted in this situation (unless both apps A and B are deleted). I guess that is to be expected as they both use the same group id and the OS won't clear that area out unless both apps are deleted. However I think I am seeing a situation where if app A has group.com.mycompany.A as its group and app B has group.com.mycompany.B as its group, then this is still the same situation - data written by app B for doesn't get deleted if only app B is deleted/reinstalled on the phone. It won't get deleted unless both app B and A are deleted from the phone. This is not what I was expecting. I need to perform some more checks (its more complex to verify as app A is developed by one company and app B by another), but if this were to be the case would this be unexpected behavior by the OS? Presumably it would be unexpected as the container should be identified by the full group id and not a partial portion of the group id right?

Hi Team, How do I prevent screenshots using SwiftUI. I was using this solution on UIKit: extension UIView { func makeSecure() { DispatchQueue.main.async { let protectedView = UIView() self.superview?.addSubview(protectedView) // constraints... let secureView = SecureView() self.superview?.addSubview(secureView) // constraints... secureView.addSecureSubview(self) // constraints... } } } class SecureView: UIView { private lazy var secureField: UIView = { var secureField: UIView = UIView() // ... if let secureContainer = SecureField().secureContainer { secureField = secureContainer } ... return secureField }() required init() { ... } } Is it posible to do the same thing using SwiftUI. Do we have an example? What would you recommend when we work with confidencial information in SwiftUI like bank account information? Thanks in advance!

Hi all, It has been >30 days since my app was removed, and I was served with the pending account termination notice. Similar to others, I was flagged for section 3.2(f). Submitted an appeal, explicitly addressing every possible violation, offered to show source code with entire history, and also have all the email threads of me providing customer support to my users, and also multiple 5 star reviews. However, I was met with the rejection and the confirmation that the account would be terminated. Fast forward more than 30 days, my account is still here, but no closure or clarification at all regarding what I can do moving forward. Understandably, the team deals with millions of submissions and apps, but isn’t it reasonable (given that we pay $100/yr) to at least get some clarification on what went wrong? Currently, all I want to know is, Can I create a new account and develop other apps? Or will I risk getting banned again, hence wasting another $100? If I am able to proceed, what do I need to do to make sure my app doesn’t get randomly terminated again? Why aren’t there any signs or warnings? If anyone is able to assist me on this, I would greatly appreciate it. Thank you so much!

Is the Cancel button intentionally removed from UISearchBar (right side)? Even when using searchController with navigationItem also. showsCancelButton = true doesn’t display the cancel button. Also: When tapping the clear ("x") button inside the search field, the search is getting canceled, and searchBarCancelButtonClicked(_:) is triggered (Generally it should only clear text, not cancel search). If the search text is empty and I tap outside the search bar, the search is canceled. Also when I have tableview in my controller(like recent searches) below search bar and if I try to tap when editing started, action is not triggered(verified in sample too). Just cancellation is happening. In a split view controller, if the search is on the right side and I try to open the side panel, the search also gets canceled. Are these behaviors intentional changes, beta issues, or are we missing something in implementation?

In iOS AP-mode onboarding for IOT devices, why does the iPhone sometimes stay stuck on the device Wi-Fi (no internet) and fail to route packets to the device’s local IP, even though SSID is correct? Sub-questions to include: • Is this an iOS Wi-Fi auto-join priority issue? • Can AP networks become “sticky” after multiple joins? • How does iOS choose the active routing interface when Wi-Fi has no gateway? • Why does the packet never reach the device even though NWPath shows WiFi = satisfied?

We are facing a DNS resolution issue with a specific ISP, where our domain name does not resolve correctly using the system DNS. However, the same domain works as expected when a custom DNS resolver is used. On Android, this is straightforward to handle by configuring a custom DNS implementation using OkHttp / Retrofit. I am trying to implement a functionally equivalent solution in native iOS (Swift / SwiftUI). Android Reference (Working Behavior) : val dns = DnsOverHttps.Builder() .client(OkHttpClient()) .url("https://cloudflare-dns.com/dns-query".toHttpUrl()) .bootstrapDnsHosts(InetAddress.getByName("1.1.1.1")) .build() OkHttpClient.Builder() .dns(dns) .build() Attempted iOS Approach I attempted the following approach : Resolve the domain to an IP address programmatically (using DNS over HTTPS) Connect directly to the resolved IP address Set the original domain in the Host HTTP header DNS Resolution via DoH : func resolveDomain(domain: String) async throws -> String {     guard let url = URL(         string: "https://cloudflare-dns.com/dns-query?name=\(domain)&type=A"     ) else {         throw URLError(.badURL)     }     var request = URLRequest(url: url)     request.setValue("application/dns-json", forHTTPHeaderField: "accept")     let (data, _) = try await URLSession.shared.data(for: request)     let response = try JSONDecoder().decode(DNSResponse.self, from: data)     guard let ip = response.Answer?.first?.data else {         throw URLError(.cannotFindHost)     }     return ip } API Call Using Resolved IP :  func callAPIUsingCustomDNS() async throws {     let ip = try await resolveDomain(domain: "example.com")     guard let url = URL(string: "https://(ip)") else {         throw URLError(.badURL)     }     let configuration = URLSessionConfiguration.ephemeral     let session = URLSession(         configuration: configuration,         delegate: CustomURLSessionDelegate(originalHost: "example.com"),         delegateQueue: .main     )     var request = URLRequest(url: url)     request.setValue("example.com", forHTTPHeaderField: "Host")     let (_, response) = try await session.data(for: request)     print("Success: (response)") } Problem Encountered When connecting via the IP address, the TLS handshake fails with the following error: Error Domain=NSURLErrorDomain Code=-1200 "A TLS error caused the secure connection to fail." This appears to happen because iOS sends the IP address as the Server Name Indication (SNI) during the TLS handshake, while the server’s certificate is issued for the domain name. Custom URLSessionDelegate Attempt :  class CustomURLSessionDelegate: NSObject, URLSessionDelegate {     let originalHost: String     init(originalHost: String) {         self.originalHost = originalHost     }     func urlSession(         _ session: URLSession,         didReceive challenge: URLAuthenticationChallenge,         completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void     ) {         guard challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust,               let serverTrust = challenge.protectionSpace.serverTrust else {             completionHandler(.performDefaultHandling, nil)             return         }         let sslPolicy = SecPolicyCreateSSL(true, originalHost as CFString)         let basicPolicy = SecPolicyCreateBasicX509()         SecTrustSetPolicies(serverTrust, [sslPolicy, basicPolicy] as CFArray)         var error: CFError?         if SecTrustEvaluateWithError(serverTrust, &error) {             completionHandler(.useCredential, URLCredential(trust: serverTrust))         } else {             completionHandler(.cancelAuthenticationChallenge, nil)         }     } } However, TLS validation still fails because the SNI remains the IP address, not the domain. I would appreciate guidance on the supported and App Store–compliant way to handle ISP-specific DNS resolution issues on iOS. If custom DNS or SNI configuration is not supported, what alternative architectural approaches are recommended by Apple?

I would like to inquire about Apple's recommended best practices for iPhone thermal management. Specifically, what actions are developers expected to take to prevent the device from overheating? I am aware that we should subscribe to Thermal State Notifications and throttle performance accordingly—such as by reducing streaming quality or temporarily disabling active features. Beyond these measures, are there any other strategies you recommend to mitigate thermal issues and help the device cool down?

When you use .navigationTransition(.zoom(sourceID: "placeholder", in: placehoder)) for navigation animation, going back using the swipe gesture is still very buggy on IOS26. I know it has been mentioned in other places like here: https://developer.apple.com/forums/thread/796805?answerId=856846022#856846022 but nothing seems to have been done to fix this issue. Here is a video showing the bug comparing when the back button is used vs swipe to go back: https://imgur.com/a/JgEusRH I wish there was a way to at least disable the swipe back gesture until this bug is fixed.

From watching the video on App Attest the answer would appear to be no, but the video is a few years old so in hope, I thought I would post this question anyway. There's several scenarios where I would like a notification service extension to be able to use App Attest in communications with the back end(for example to send a receipt to the backend acknowledging receipt of the push, fetching an image from a url in the push payload, a few others). Any change App Attest can be used in by a notification service extension?

I'm using a custom modifier called AutoSheetDetentModifier to automatically size a sheet based on its content. On iOS 26, it works as expected: the content height is measured correctly and the sheet shrinks to match that height. However, on iOS 16, 17 and 18, the same code doesn’t work. The content height is still measured, but the sheet does not reduce its height. Instead, the sheet remains larger and the content appears vertically centered. (Note that content() includes ScrollView) public struct AutoSheetDetentModifier: ViewModifier { @State private var height: CGFloat = 380 // default value to avoid bouncing public func body(content: Content) -> some View { content .modifier(MeasureHeightViewModifier(height: $height)) .presentationDetents([.height(height)]) } } public struct MeasureHeightViewModifier: ViewModifier { @Binding var height: CGFloat public func body(content: Content) -> some View { content .fixedSize(horizontal: false, vertical: true) .background( GeometryReader { geo -> Color in DispatchQueue.main.async { height = geo.size.height } return Color.clear } ) } } extension View { public func applyAutoSheetDetent() -> some View { self .modifier(AutoSheetDetentModifier()) } } public var body: some View { VStack { header() content() // includes ScrollView footer() } .background(Color.customGray) .applyAutoSheetDetent() } func content() -> some View { ScrollView { VStack { ForEach(items) { item in itemRow(item) } } } .frame(maxHeight: UIScreen.main.bounds.height * 0.7) } Screenshot from iOS 26 (working as expected): Screenshot from iOS 18 (not working): How can I make .presentationDetents(.height) shrink the sheet correctly on iOS 16–18, the same way it does on iOS 26?

My app allows to save user-selected URLs in a list and browse them with a tap. A user reported that the app often shows that when browsing their saved entry for "On My iPad", it's apparently empty (it contains no files). I saved "On My iPad" in my own list some time ago and noticed that the same issue occurs. The URL seems to be correctly resolved from the saved bookmark data, but I noticed that url.startAccessingSecurityScopedResource() returns false. The other URL I saved some time ago is iCloud Drive, which I can access without issues. If I select "On My iPad" again in a file importer, create new bookmark data from it and resolve the URL from it, access works correctly. I create bookmark data like this: let data = try url.bookmarkData(includingResourceValuesForKeys: [.localizedNameKey, .pathKey, .volumeIsLocalKey]) and resolve URLs like this: let url = try URL(resolvingBookmarkData: data, bookmarkDataIsStale: &bookmarkDataIsStale) bookmarkDataIsStale is false for both the working and not working URLs for "On My iPad". The two bookmark data are different though, even if url.path is the same. What could be the issue?

Device: iPhone 17 Series System: iOS 26.0.0 Wi-Fi: TKIP encryption protocol Question: Unable to join the network We have several products that are used by connecting to iPhone via Wi-Fi. Recently, many customers who have purchased the iPhone 17 series have reported that they are unable to connect to Wi-Fi. For Wi-Fi with TKIP encryption, after entering the password correctly to connect to the Wi-Fi, a pop-up appears stating "Unable to join the network.". Only Wi-Fi with WPA2-AES can be used normally. Before that, during the iPhone 11 era or even earlier, the TKIP encryption method was in normal use. However, the new iPhone models were incompatible with it, which obviously caused great inconvenience. I hope the engineers can fix this issue to support Wi-Fi with older encryption protocols.

I'm trying to sync authentication data from my iOS app to a Safari Web Extension using App Groups, but the extension isn't consistently receiving the data. Setup: App Group: group.com.airaai.AiraApp (configured in both app and extension) iOS app writes auth data using UserDefaults(suiteName: "group.com.airaai.AiraApp") Extension's Swift SafariWebExtensionHandler reads from App Groups in beginRequest() Extension's JavaScript reads from browser.storage.local Problem: Extension popup always shows "logged out" even when: User is logged into main iOS app Auth data exists in App Groups (verified via native module logs) Handler successfully writes test values to extension storage Current Behavior: Handler CAN read from App Groups ✅ Handler CAN write test values to extension storage ✅ But auth data doesn't appear in browser.storage.local when popup checks ❌ Popup reads empty keys even though handler logged writing them Code: // Handler reads from App Groups guard let sharedDefaults = UserDefaults(suiteName: "groupName") else { return } let authData = sharedDefaults.string(forKey: "auth_data") // Handler writes to extension storage (tried multiple suite names) let extensionDefaults = UserDefaults(suiteName: Bundle.main.bundleIdentifier ?? "") extensionDefaults?.set(authData, forKey: "oauth_token") extensionDefaults?.synchronize() // Popup reads from storage browser.storage.local.get(['oauth_token']).then(data => { console.log(data); // Always empty {} }); What I've tried: ✅ App Groups properly configured in both targets ✅ Extension has App Groups capability enabled ✅ Multiple UserDefaults suite names (bundle ID, bundle ID + suffix) ✅ Delayed sync attempts in handler ✅ Comprehensive logging Questions: What is the correct UserDefaults suite name for Safari extension storage on iOS? When does beginRequest() get called? Can it be triggered manually? Is App Groups the right approach, or should I use a different pattern? Alternatives I've considered: Deep link/redirect method (app opens Safari with token in URL) Content script intercepts URL and sends to background script Is this a supported approach for iOS Safari extensions? Any guidance or examples would be greatly appreciated!

Hello everyone! I'm a newly graduated Computer Engineer living in Türkiye. I've been developing my skills in the iOS field for a while now. But sometimes I get lost and don't know what to do. I've just joined this community and have a request for you. I'd be very grateful if you could share your own advice, experiences you've had along the way, and how you successfully overcame them. I'm open to all kinds of positive or negative feedback. Self-improvement is paramount to me.

We're seeing sporadic crashes on devices running iOS 18.1 - both beta and release builds (22B83). The stack trace is always identical, a snippet of it below. As you can tell from the trace, it's happening in places we embed SwiftUI into UIKit via UIHostingController.

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?

From https://developer.apple.com/forums/thread/803945?answerId=862153022#862153022, the testing of Age Range API was not available through xcode simulator back in Oct 2025. Is this available now? In particular: Is requestAgeRange testing available through simulator? Is requestAgeRange testing with sandbox account available through simulator? Is isEligibleForAgeFeatures available through simulator? Is isEligibleForAgeFeatures testing with sandbox account available through simulator? If the answer is "yes" to any of the above, which version of the xcode and ios version should I use? So far I didn't get any of the above working on the simulator, and I can't find any documentation on the answers above. Thank you!
