RTT call option and confirmation dialog missing when dialing emergency numbers
Hello, In our app we provide a button that initiates a phone call using tel://. For normal numbers, tapping the button presents the standard iOS confirmation sheet with Call and Cancel. If RTT is enabled on the device, the sheet instead shows three options: Call, Cancel, and RTT Call. However, when dialing a national emergency number, this confirmation dialog does not appear at all — the call is placed immediately, without giving the user the choice between voice or RTT. Is this the expected system behavior for emergency numbers on iOS? 
And if so, how does RTT get applied in the emergency-call flow — is it managed entirely by the OS rather than exposed as a user-facing option? Thanks in advance for clarifying.

Device enrollment to ABM failing with timeout during setup
Hello, I’m facing an issue while trying to add iOS devices to Apple Business Manager (ABM) using Apple Configurator during enrollment. When going through the setup process, the device fails to complete enrollment and times out. I’ve tried it multiple times. The device does appear in ABM during the process and I am able to assign it to different MDM servers but since the setup times out and fails, the device is automatically released. I have tried this with multiple iOS devices and it times out on every single one of them. Steps attempted: Factory reset and re-enrollment of the device Ensured network connectivity is stable and tested on multiple Wi-Fi networks Tried the following process using Apple Configurator on Mac (wired): Created a Wi-Fi profile in Configurator Connected the iPhone via cable and used Prepare (manual configuration) Used the “MDM server” placeholder and trusted anchors (as recommended) Linked the device to the ABM organization Skipped Setup Assistant steps Attached the Wi-Fi profile, then prepared and wiped the device Verified that the device should appear in ABM Attempted to assign the device to my MDM in ABM Despite these checks, the enrollment process times out. I’m attaching a screenshot of the error for reference. Could someone advise what might be causing this timeout or how I can further troubleshoot this? Any guidance would be greatly appreciated. Thanks in advance.

App Clip Card’s “Open” Button takes 2–3 seconds to become active on first load
We are currently implementing App Clips in our app. While we have carefully optimized the App Clip size to keep it lightweight (~3.69MB), we have noticed that on the first load, displaying the App Clip Card and activating the “Open” button takes a surprisingly long time (approximately 2–3 seconds). Subsequent loads appear to perform normally. We understand that this behavior may not be directly controllable from the app development side, but we would like to know if there are any possible ways to improve it. Minimizing the time it takes for users to access the content is extremely important, as delays on the first interaction can negatively impact the user experience. Any guidance or best practices to make the App Clip Card and its “Open” button respond faster on first load would be greatly appreciated.

Avoid using a segmented control in a toolbar
Hi, in the Human Interface Guidelines, Apple writes: Avoid using a segmented control in a toolbar. Toolbar items act on the current screen — they don’t let people switch contexts like segmented controls do. Along with this image: Source I'm confused by this example. The screenshot seems to be showing a segmented control in a toolbar. Is this saying that the Phone app's All/Missed toggle is different from a segmented control? Under iOS 26 it seems to take a different style compared to a regular segmented control. If so, which component is used to create this filter? Could you please clarify the guidelines? Thank you.

Local Hotspot
Hello, we are developing hardware that needs to connect to an iPhone via Wi-Fi to send requests to a server. On Android, we have managed to create a programmatic local hotspot within the app to facilitate connection and improve the user experience. On iOS, however, Personal Hotspot must be manually enabled from the system settings, and the user must manually enter the SSID and password, which significantly degrades the UX. My questions are: Is there a workaround, unofficial method, or private API to generate a local hotspot from an app on iOS, similar to what can be done on Android? Is there an alternative within the MFi program or through specific frameworks to facilitate a quick and automatic connection between the hardware and the iPhone without relying on the manual Personal Hotspot? Are there any best practices for improving the local Wi-Fi connection experience between an accessory and an iPhone in the absence of hotspot controls? I would appreciate any guidance, experience, or resources that would help me better understand the feasible options in iOS for scenarios where fast and direct communication between hardware and mobile devices via Wi-Fi is required.

ICDeviceBrowser authorization requests always return ICAuthorizationStatusNotDetermined on iOS 26.1 beta
Area ImageCaptureCore / ICDeviceBrowser Description On iOS 26.1 beta, calling requestControlAuthorization() requestContentsAuthorization() always returns .notDetermined and never transitions to .authorized or .denied. This prevents apps from properly accessing device control or contents authorization. The issue occurs regardless of device state or prior requests. Steps to Reproduce 1. Create and start an ICDeviceBrowser instance. 2. Call requestControlAuthorization() or requestContentsAuthorization(). 3. Inspect the returned ICAuthorizationStatus. Expected Result • The system should prompt the user if necessary. • A final status of either .authorized or .denied should be returned. Actual Result • The completion handler always reports .notDetermined. • No user prompt appears and the status does not change. Version / Build • iOS 26.1 beta • Xcode Hardware • [iPhone 15 Pro, iPad Pro (M2)] Impact This regression blocks development and testing of features relying on ImageCaptureCore. Applications depending on device browsing and content access cannot proceed, which significantly affects workflows involving external device integration. Notes This appears to be a regression compared to earlier iOS releases.

Chaotic keyboard frame notification in windowed app in iOS 26
I have a simple task, to measure the height of the overlapping area occupied by the keyboard in the current view. In the attached images, I use it to position a UITextView (red) above the keyboard, as a test. The keyboard displays an inputAccessoryView (yellow) when editing a text view, but it’s also summoned by a UIFindInteraction, which shows a search bar above the keyboard. When measuring the keyboard, I need to account for either the accessory view or the search bar, basically, the total keyboard height including any extra views above it. I use the usual algorithm: the keyboard frame from UIResponder.keyboardWillShowNotification (documented as being in screen coordinates) is converted to my view’s coordinates and intersected with the view’s bounds to get the overlapping height. The first issue: in windowed mode, the keyboard frame reports a negative origin.x (e.g. -247), even though in screen coordinates it should start at 0. I display the raw frame in the navbar, as shown in the first screenshot. I then suspected the frame might be in window coordinates on iOS 26, but repositioning the window a few times, and switching between find interaction keyboard and text editing keyboard, sometimes yields a positive origin.x instead, as if the keyboard starts from the middle of the screen!? (see the second screenshot). And in some cases, the raw keyboard height is even 0, despite the keyboard clearly being visible and taking space (third screenshot). Interestingly, the reported frame for the search keyboard is always consistent and in screen coordinates, but the default keyboard frame just doesn’t make sense.

Microphone is not being detected in Safari on iOS
What I am trying to do is very simple. Environment description: macOS Catalina version 10.15.7 iOS Simulator version 12.3 Target device iPhone 11 (iOS 13.2.2) Open Safari > go to website > mictests.com Result: "Could not find any media devices. It is very likely that your browser does not allow access to these devices." The Simulator does have access to the microphone. I can use Siri just fine. Only Safari cannot access the mic. I'm really stuck here, any ideas are welcome.

How to enable the "Paste and Match Style" context menu in a UITextView?
The UIResponderStandardEditActions protocol includes pasteAndMatchStyle:. UITextView conforms to UIResponderStandardEditActions. But I can't find a way to get that menu to appear. I get the standard "Paste" menu. I've tried overriding pasteAndMatchStyle: in a subclass of UITextView. I've overridden canPerformAction:withSender: but it never gets called with the pasteAndMatchStyle: selector. I've implemented the textView:editMenuForTextInRange:suggestedActions: delegate method. It's called but the suggested actions do not include the "Paste and Match Style" action (key command). I came up with an ugly hack that involved overriding buildMenuWithBuilder: and adding my own key command after the paste command. But this shouldn't be necessary considering it's supposed to be a standard edit action. So what's the trick to make the "Paste and Match Style" edit menu appear properly in a UITextView? I'm testing with iOS 17, 18, and 26.

Incorrect color for inline navigation bar title when dark mode AND reduce transparency ON.
I reproduced this in iPhone 17 and iPhone 17 Pro simulators running iOS 26.0 import SwiftUI struct ContentView: View { var body: some View { NavigationStack { ScrollView { VStack { ForEach(0..<100) { i in Text("Row \(i)") .frame(maxWidth: .infinity) } } .padding() } .navigationTitle("Toolbar Test") .navigationBarTitleDisplayMode(.inline) // or .automatic } } } Run this code in a vanilla SwiftUI app. Toggle the appearance to dark mode. In the simulator's Settings app -> Accessibility -> Display and Text Size. Turn ON "Reduce Transparency". Go back to the app and start scrolling if you need to. You can observe that the title is unreadable - black text on a black navigation bar.

iOS 26 & Xcode 26 - bug with keyboard by WebView
Environment iOS 26 (23A343) Xcode 26 Reproduces on device and Simulator Description When presenting a SwiftUI WebView (native iOS 26 component) or a WKWebView/UIWebView via UIViewRepresentable, focusing a text field inside the web view and then dismissing it breaks the keyboard layout behavior. After returning to the main app, tapping any TextField causes the keyboard to cover bottom controls (e.g. buttons). Expected safe area insets are not applied. The issue is only resolved after closing and reopening the keyboard once. Steps to Reproduce Open a SwiftUI screen with WebView (via .sheet or NavigationLink). Inside the web view, tap a text field to show the keyboard. Dismiss the web view. Tap a TextField in the main app. Expected Result Layout should adjust correctly. Bottom controls stay visible above the keyboard. Actual Result Keyboard covers bottom controls. Insets are ignored until the keyboard is dismissed and reopened. Notes Reproduces with: Native SwiftUI WebView (iOS 26) WKWebView and UIWebView via UIViewRepresentable Presentation style (.sheet or navigation push) does not matter. Example video: https://youtu.be/Epgoz1vETKU FB: FB20386257 Sample Code import SwiftUI import WebKit struct ContentView: View { @State var url: URL? @FocusState private var isFocused: Bool var body: some View { VStack { TextField("TextField", text: .constant("")) .focused($isFocused) Button("HIDE KEYBOARD") { isFocused = false } Spacer() Button("ACTION") { url = URL(string: "https://google.com") } } .sheet(item: $url) { value in NavigationStack { WebView(url: value) .toolbar { ToolbarItem(placement: .topBarLeading) { Button("CLOSE") { url = nil } } } } } } } extension URL: Identifiable { public var id: String { absoluteString } }

View title misaligned after compiling with Xcode 26
After compiling with Xcode 26, my UIKit view's title appears hugging the screen on the left when run on iOS 16-18 (as shown in the image below). It's fine when run on iOS 26, but not older iOS versions. When I compile the same code with Xcode 16.4, the title aligns with the table rows. Has anyone else seen this? Is this a bug in the frameworks or is there something I could do to resolve?

iOS Safari Web Extension MV3 - How to debug service workers?
I'm developing a web extension for Safari on iOS using MV3. The extension is working fine in Chrome, but in Safari I experience some seemingly random issues. I would like to debug it, but here is my problem. I have my iPhone connected via cable to Mac, and it works fine with XCode, so I assume this part is OK. I open Safari or Safari Tech Preview (doesn't matter) on my Mac, developers options are enabled, and in the Develop menu, under my iPhone section, there are things I can debug. There is an entry "[Ext name] - Extension Service Worker" but when I click it, it's empty. Web inspector pops up, but there are no network requests, no logs, nothing. I know the extension is working, because I can stream log to my HTTP server, but I don't see them here at all. I can use console to trigger commands like chrome.storage.local.get(null, console.log) and it shows my local store, so why I don't see any logs? Also, the background script is not visible in the Sources tab, just one weird request: navigator.serviceWorker.register('safari-web-extension://E3449EA7-EC25-4696-8E6C-[ID HERE]/background.js'); </script> Any ideas what went wrong? The entire team of 4 people has the same issue and we can't move forward because of that. Also, the Develop => Service workers or any other menu section doesn't show my service worker. Logs for websites running on my phone are visible and in general web inspector for them works fine.

unable to cancel test subscriptions
I tested a subscription with my developer account, it never charges but at the same time I can't cancel it anymore. It does not appear in the list of my official purchsed subscriptions. I tried to login to the sandbox with my developer account, but then when I click on "Manage" I just keep getting the error "Can't connect - retry". I have already tried to logout from all the services, App store, etc. and re-login, nothing worked. Is there anything I can do? Thanks in advance to anyone who can give any tips.

How to capture 48MP capture with Ultra wide lens using iPhone 16 pro max
I am working on capturing 48MP images using the iPhone 16 Pro Max with the Ultra-wide camera. I’ve updated the code to capture the maximum supported dimensions with the following snippet: if #available(iOS 16.0, *) { photoOutput.maxPhotoDimensions = device.activeFormat.supportedMaxPhotoDimensions.last! photoSettings.maxPhotoDimensions = .init(width: 5712, height: 4284) } However, I’m still not getting the expected results. My goal is to capture 48MP images, and I want to confirm if the Ultra-wide camera supports this resolution or if I’m missing any other configuration. Any guidance would be appreciated!

iOS 16 recurring payment configuration not reflecting in UI
We are integrating iOS 16 recurring payments in our app, everything works fine but we have a few questions Question 1 let recurringPaymentRequest = PKRecurringPaymentRequest(         paymentDescription: "Pro Membership",         regularBilling: regularBilling,         managementURL: url       ) we assume managementURL is supposed to come in the user's wallet where he/she can tap to change the recurring payment option to our backend, but in the wallet, the transaction appears without this URL and have no indication that it is a recurring payment, Can someone guide what we missed Question 2 For apps that only have apple pay on mobile, managementURL can open the app as a deep link from the Wallet app and the user can update or delete the payment method for the automatic reload payment from the app directly, Question 3 For cancellation, the recurring payment app should have some UI where the user can tap which hit our backend and remove the apple pay merchant token from our system and apply cancellation business logic, no apple API involves in the cancellation of recurring payment

Custom Background Image Fails to Display on UIToolbar
I am encountering a critical issue where a custom background image on a UIToolbar fails to display when the app is built with Xcode 26 and run on iOS 26 beta. The exact same implementation works perfectly on iOS 18 and earlier versions. We first attempted to use the legacy setBackgroundImage method, which fails to render the image on iOS 26: // 1. Get Navigation Bar and set basic properties UINavigationBar* navBar = self.navigationBar; navBar.hidden = NO; navBar.translucent = NO; // 2. Setup the UIToolbar instance UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:navBar.bounds]; toolBar.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; // 3. Set the resizable image (This image does not appear on iOS 26) UIImage* imagePortrait = [UIImage imageNamed:@"nav_bg"]; UIEdgeInsets insets = UIEdgeInsetsMake(0.f, 6.f, 0.f, 6.f); [toolBar setBackgroundImage:[imagePortrait resizableImageWithCapInsets:insets] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault]; We then migrated to the recommended modern UIToolbarAppearance to solve this, but the issue persists: // 1. Prepare Image UIImage* imagePortrait = [UIImage imageNamed:@"nav_bg"]; // Insets are applied via resizableImageWithCapInsets: (not shown in this snippet but implied) // 2. Configure UIToolbarAppearance UIToolbarAppearance *appearance = [[UIToolbarAppearance alloc] init]; appearance.backgroundImage = imagePortrait; // The image is correctly loaded (not nil) // 3. Apply the Appearance toolBar.standardAppearance = appearance; // We also applied to scrollEdgeAppearance and compactAppearance. Any information or recommended workarounds for displaying a custom background image on UIToolbar in the latest iOS 26 would be highly appreciated.

AppGroups data loss after App transfer and App update.
Hi, I just released a new version of an app that was transferred from another developer account. The previous version of this app used the App Groups feature to store some important data, and I would like to retrieve that data. In the new version, I’m using the same bundle identifier and the same App Group ID (which has already been deleted from the original developer account). I also added the App Groups entitlement in the project settings and set the same App Group ID. However, I still cannot access the data in the App Group. From the documentation and issues I’ve found, it seems that an app should still have permission to access the same App Group after being transferred. Did I miss something? Thanks!
