Hi, I have a document-based SwiftUI multiplatform app, where the document is saved as JSON. Obviously I don't want Quick Look to show the JSON of my file, so I made a Quick Look Preview extension for each platform. The macOS one works… okay, sometimes it's tricky to test and I need to use qlmanage to empty the cache or to show the preview, but it does work. I can even debug it. But the iOS one just never seems to be run. If I show Quick Look in the Files app on iOS, or if I AirDrop a file from my app to my iPhone, it shows as JSON, with an option to open it in my app. If I run the iOS Preview Extension in the debugger and launch the Files app, and then try to use Quick Look in a file there, it shows the JSON and the debugger just stays in the state 'Waiting to Attach'. The preview extensions are not data based; in both of them I have implemented func preparePreviewOfFile(at url: URL) async throws in PreviewViewController.swift. Pretty much the same code except one is using a UIHostingController and the other is using an NSHostingController. The only difference in the Info.plists for the two extensions is that the iOS one uses NSExtensionMainStoryboard while the macOS one uses NSExtensionPrincipalClass. This is how they were set up when I created them from the relevant Quick Look Preview Extension templates. I made a sample project with a much simpler document, UI, etc. and I have the same issue there. The macOS preview works, the iOS one never runs. I have checked that the correct preview extension is embedded in the target for each OS (under Embed Foundation Extensions in the Build Phases) Is there anything I need to do differently in iOS, or anything I might have inadvertently got wrong? Is there a way to run something similar to qlmanage on iOS, since that sometimes seems to help on macOS? Incidentally, I have also added Quick Look Thumbnail extensions, and they work on both platforms.

as a beta tester I am trying to explore the OS on multiple platforms like iO, iPadOS, MacOS, WatchOS. While on trying to use beta 1 have few issues and reported to Apple with analytics as I do for better improvements. But, in beta 2 there is an issue of glitches on UI. This also tried to report. But, while am trying record screen I can not see in that video after the screen record. But, in reality I can see that glitch with eyes. as everyone know without evidence we can not report the same with tickets properly and they also can not resolve the issues. It’s affecting on all types of OS platforms of Apple buttons and search positions etc. one more thing I absorbed is while am trying use overlay player and browse the safari or any apple developer apps which are full screen the devices are freezing and not responding and after hard restart those are starting after 10mins. As per my knowledge. Those are going through the memory overflow issue.

I have a transformation function that takes in data, executes some instructions, and returns an output. This function is dynamic and not shipped with the binary. Currently, I’m executing it using JavaScriptCore.JSContext, which works well, but the function itself is written in JavaScript. Is there a way to achieve something similar using Swift – such as executing a dynamic Swift script, either directly or through other means? I know this is possible on macOS, but I’m not sure about iOS. I’ve also heard that extensions might open up some possibilities here. Any insights or alternative approaches would be appreciated.

I'm developing a calculator app and working to ensure a great experience for both VoiceOver and Braille display users. For expressions like (2+3)×5, I need two different accessibility outputs: VoiceOver (spoken): A descriptive string like “left paren two plus three right paren times five,” provided via .accessibilityValue. I'm using a custom spellOut function since VoiceOver doesn't announce parentheses—which are kind of important when doing math! Braille (symbolic): The literal math string (2+3)×5, provided using .accessibilityCustomContent("", ...), with an empty label so it’s not spoken aloud. The issue: I don’t have access to a Braille display device and Xcode’s Accessibility Inspector doesn’t seem to show the custom content. Is there any way to confirm that custom Braille content is being set correctly in Simulator or with other tools? Or…is there a "math mode" in VoiceOver that forces it to announce parentheses? Any advice or workarounds would be much appreciated! Thanks, Uhl

I am checking the response of DeviceInformation Command to collect network information from iPad. On iPad(iPad Pro 11, M4) devices that use WiFi without inserting Usim or Esim, network values ​​such as CurrentMCC and ICCID are received in response to the DeviceInformation command. cf.)Even though it may be garbage value, I blurred the unique information just in case. <key>ServiceSubscriptions</key> <array> <dict> <key>CarrierSettingsVersion</key> <string>61.0</string> <key>CurrentCarrierNetwork</key> <string></string> <key>CurrentMCC</key> <string>450</string> <key>CurrentMNC</key> <string>08</string> <key>EID</key> <string>blah blah</string> <key>ICCID</key> <string>blah balh</string> <key>IMEI</key> <string>blah blah</string> <key>IsDataPreferred</key> <true/> <key>IsRoaming</key> <true/> <key>IsVoicePreferred</key> <false/> <key>Label</key> <string>Provisioning</string> <key>LabelID</key> <string>00000000-0000-0000-0000-000000000000</string> <key>PhoneNumber</key> <string></string> <key>Slot</key> <string>CTSubscriptionSlotOne</string> <key>SubscriberCarrierNetwork</key> <string>iPad</string> </dict> </array> This is a bit weird. If I collect the same information from an iPhone(iPhone 15 Pro Max) that only uses wifi and does not use Usim or Esim, it does not respond with values ​​like ICCID, CurrentMCC, etc. <key>ServiceSubscriptions</key> <array> <dict> <key>IMEI</key> <string>blah blah</string> <key>Slot</key> <string>CTSubscriptionSlotOne</string> </dict> <dict> <key>EID</key> <string>blah blah</string> <key>IMEI</key> <string>blah blah</string> <key>Slot</key> <string>CTSubscriptionSlotTwo</string> </dict> </array> I'm confused by the network information collected. Is there a reason why the collected network information of iPad and iPhone are different?

Navigation Title no longer showing for first Tab in iOS/iPadOS 26 (Directives) in my app Starship SE Corps when running is Xcode 26 simulator and on iPad device itself running iPadOS 26 beta. Launch app Notice Navigation Title “Directives” is missing from top tab in Sidebar and Floating Tab View (iPad) and TabView (iOS). Navigate to other tabs and Navigation Titles appear as expected. Worked fine (as expected) in iOS/iPadOS 18.5, but broken in iOS/iPadOS 26. Reference Feedback: FB17987650

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if (application.applicationState == UIApplicationStateBackground) { // ✅ Background launch } else { // ✅ Normal foreground launch } } Previously, when using AppDelegate to handle lifecycle methods, I could determine whether a cold start was a background launch as shown above. This allowed me to accurately measure cold start time for real-world users. The platform now requires migration to scene-based lifecycle management by iOS 16. However, after migration: In both application:didFinishLaunchingWithOptions: and scene:willConnectToSession:options: methods, application.applicationState == UIApplicationStateBackground and scene.activationState == UISceneActivationStateUnattached These values remain fixed regardless of whether it's a background launch, making them unusable for differentiation. I attempted to use information from UISceneConnectionOptions for distinction but found it ineffective. Question: Are there alternative approaches to achieve this distinction?

In the software update in the settings if I open the software update, which is showing that could not update because I accidentally turned off the beta updates and it is showing error or something

Calling button flickers when making a call after updating to ios 26 beta 2 kindly solve the issue asap

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.

After installing iOS 26 Developer Beta on my iPhone 13 mini, I encountered a critical battery issue. The battery percentage was stuck at 1%, and the phone could only be used while continuously plugged in. Despite the low reading, the device remained fully functional — I could use apps, navigate, and perform tasks normally. However, the battery indicator never rose above 1%, and the Battery Health section in Settings showed 0% Maximum Capacity, which is inaccurate. I did not allow the phone to fully discharge, out of fear that it might not turn back on. Restarting the phone and changing cables or chargers had no effect. After restoring the device to iOS 18.7.2 using DFU mode, the issue disappeared entirely — the battery percentage behaved normally again and the health section showed the correct value (about 100%). Observed behavior: • Battery percentage frozen at 1% • Maximum Capacity reported as 0% • Device only functional while connected to power • Issue resolved immediately after restoring to iOS 18 Temporary solution: A DFU restore to iOS 18 (18.5 22F76) immediately resolved the issue. The battery percentage and health readings returned to normal. Additional information: • Charger used: Official Apple 20W USB-C charger • Cable used: Apple USB-C to Lightning cable • Battery health after restore: 100% (replaced)

After IOS 26 beta 2 installation in my iphone 13, I can't do a screenshot using assistivetouch nor touch on back.

I am seeing a strange issue where NSObject accessibilityRespondsToUserInteraction returns true on Simulator but false on device. Checking the same object on simulator with Accessibility inspector I see the object traits as image so why would it return true in that case? Are there any other way to check the the item might be accessibilityRespondsToUserInteraction OR Clickable beside that property and traits? (Or is it just another bug)

While editing the search text using the external keyboard (with VoiceOver on), if I try to navigate the to List using the keyboard, the focus jumps back to the search field immediately, preventing selection of list items. It's important to note that the voiceover navigation alone without a keyboard works as expected. It’s as if the List never gains focus—every attempt to move focus lands back on the search field. The code: struct ContentView: View { @State var searchText = "" let items = ["Apple", "Banana", "Cherry", "Date", "Elderberry", "Fig", "Grape"] var filteredItems: [String] { if searchText.isEmpty { return items } else { return items.filter { $0.localizedCaseInsensitiveContains(searchText) } } } var body: some View { if #available(iOS 16.0, *) { NavigationStack { List(filteredItems, id: \.self) { item in Text(item) } .navigationTitle("Fruits") .searchable(text: $searchText) } } else { NavigationView { List(filteredItems, id: \.self) { item in Text(item) } .navigationTitle("Fruits") .searchable(text: $searchText) } } } }

My company has a server that supports ticket-based TLS session resumption (per RFC 5077). We have done Wireshark captures that show that our iOS client app, which uses URLSession for REST and WebSocket connections to the server, is not sending the TLS "session_ticket" extension in the Client Hello package that necessary to enable ticket-based resumption with the server. Is it expected that URLSession does not support ticket-based TLS session resumption? If "yes", is there any way to tell URLSession to enable ticket-based session resumption? the lower-level API set_protocol_options_set_tls_tickets_enabled() hints that the overall TLS / HTTP stack on IOS does support ticket-based resumption, but I can't see how to use that low-level API with URLSession. I can provide (lots) more technical details if necessary, but hopefully this is enough context to determine whether ticket-based TLS resumption is supported with URLSession. Any tips / clarifications would be greatly appreciated.

Hello Apple Developer Community and Apple Team, I want to raise awareness and gather support for an important feature request regarding NFC support on iPhone devices in Argentina. Millions of Argentinians use the official public transit card, SUBE, daily to pay for buses, subways, and trains. On Android devices, the SUBE app allows users to: • Check balance via NFC • Reload credit instantly • Confirm top-ups by holding the card near the phone • Use a digital version of the card (in some cases) However, iPhone users cannot use these NFC features because iOS currently does not allow third-party apps like SUBE to access the NFC chip fully. This limitation negatively impacts iPhone users, many of whom rely heavily on SUBE. I have submitted detailed feedback to Apple requesting the enablement of controlled NFC access for third-party transit apps in Argentina, starting with SUBE. I encourage fellow developers, users, and community members to support this request. Enabling this would greatly improve the user experience for millions of iPhone users, align Apple with local needs, and potentially attract new customers from Android. If anyone has insights or updates on this topic, please share. Thank you.

I’m updating my app’s alternate icons using UIApplication.shared.setAlternateIconName, and I noticed that in iOS 26, Xcode now supports the new .icon file format for App Icons. Is it possible to reference .icon files directly for alternate icons? Or does setAlternateIconName still only support traditional .png assets inside the AppIcon set? I couldn’t find any documentation confirming this either way, and I want to ensure compatibility with the new format while supporting alternate icons. Any clarification or Apple documentation link would be greatly appreciated!

While testing my application on iOS beta 26, I am experiencing issues with the native UISegmentedControl component from UIKit. After implementing the control, I noticed that I am unable to switch to the second segment option—the selection remains fixed on the first segment regardless of user interaction. I have already reviewed the initial configuration of the control, the addition of the segments, and the implementation of the target-action, but the issue persists. I would like to understand what could be causing this behavior and if there are any specific adjustments or workarounds for iOS 26. I created a minimal application containing only a UISegmentedControl to clearly demonstrate the issue.
