AXSpeech Thread Crash SEGV_ACCERR
Hi everyone, I've encountered a rare and strange crash in my app that I can't consistently reproduce. The crash seems to occur deep within Apple's internal frameworks, and I can't pinpoint which line of my own code is causing it. Here's the crash stack trace: #44 AXSpeech SIGSEGV SEGV_ACCERR 0 CoreFoundation ___CFCheckCFInfoPACSignature + 4 1 CoreFoundation _CFRunLoopSourceSignal + 28 2 Foundation _performQueueDequeue + 492 3 Foundation ___NSThreadPerformPerform + 88 4 CoreFoundation ___CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 5 CoreFoundation ___CFRunLoopDoSource0 + 176 6 CoreFoundation ___CFRunLoopDoSources0 + 340 7 CoreFoundation ___CFRunLoopRun + 828 8 CoreFoundation _CFRunLoopRunSpecific + 608 9 Foundation -[NSRunLoop(NSRunLoop) runMode:beforeDate:] + 212 10 TextToSpeech _TTSCFAttributedStringCreateStringByBracketingAttributeWithString + 776 11 Foundation ___NSThread__start__ + 732 12 libsystem_pthread.dylib __pthread_start + 136 Sometimes, instead of line 10 referencing _TTSCFAttributedStringCreateStringByBracketingAttributeWithString, it shows: 10 TextToSpeech LogWarning(char const*, ...) + 7288 Has anyone experienced a similar issue or know what might be triggering this crash? Any guidance on how to investigate or resolve this would be greatly appreciated. Thank you!

Feature Idea: Autonomous, Motion-Powered Clock Display on iPhone.
Hey everyone, I've been thinking about a truly innovative way to enhance iPhone battery life and user convenience, drawing inspiration from kinetic energy harvesting. What if we could have a clock display on the main iPhone screen that's powered purely by user motion, and activates only when you look at it, without touching your main battery? The Core Idea Imagine this: Kinetic Energy Harvesting: Your iPhone would have a tiny, integrated kinetic energy generator. This generator would capture the energy from your everyday movements – walking, picking up the phone, putting it in your pocket. Independent Power Source: This harvested energy would be stored in a small, dedicated capacitor or micro-battery, completely separate from your iPhone's main battery. Acelerometer-Activated Display: Instead of relying on power-hungry facial recognition, the phone's accelerometer (a very low-power sensor) would detect specific "raise to wake" or "tap to look" gestures. On-Demand, Ultra-Low Power Clock: Only when the accelerometer detects one of these specific gestures would the stored kinetic energy be used to illuminate just the necessary pixels on the main OLED/AMOLED screen to display the time. The rest of the screen stays completely black (consuming no power on OLED). Automatic Shut-Off: As soon as the gesture ends or the phone is put down, the clock display would turn off, conserving the limited harvested energy. Why This Matters This isn't just a cool gimmick; it offers significant benefits: True Battery Independence: Get the time at a glance, anytime, without touching your main battery or even the power button. This means more main battery life for apps, calls, and everything else. Ultimate Convenience: A "magical" interaction – just pick up your phone, and the time instantly appears. No taps, no button presses. Sustainable & Innovative: Showcases practical "energy harvesting" in a consumer device, pushing boundaries for self-sufficient tech. Extreme Energy Efficiency: By using a low-power accelerometer as the trigger and only lighting a few pixels on demand, the system is designed for minimal power draw, making kinetic power a viable source. This concept combines existing low-power sensing (accelerometer), efficient display technology (OLED/AMOLED's true blacks), and cutting-edge energy harvesting, creating a genuinely innovative user experience.

Don't get the completed shipping contact after authorizaiton
We have get the response from Apple pay after the the customer doing the face ID & touch ID authorization. But the shiping contact is not complete, for examble: ` { "addressLines": [ "1************ kwy" ], "administrativeArea": "FL", "country": "", "countryCode": "", "emailAddress": "S*********le.com", "familyName": "******i", "givenName": "******m", "locality": "*******s", "phoneNumber": "+*******79", "phoneticFamilyName": "", "phoneticGivenName": "", "postalCode": "*****3", "subAdministrativeArea": "", "subLocality": "" },` as the documents said, it should be the completed shipping contact, but the country & countrycode is null https://developer.apple.com/documentation/apple_pay_on_the_web/applepaypayment/1916097-shippingcontact

The brightness of the iPad Pro screen is gone after new ios26
After 26 IOS update, the colors on my new iPad Pro M4 have become extremely dull almost like those on a very old device. The screen brightness is significantly reduced, and it's now difficult to see UI elements clearly. This is very disappointing considering the device’s high display quality before the update. Please advise if this is a known issue or if there's a fix.

Speak Selection broken with SwiftUI text
I have users who need to be able to hear the content of SwiftUI Text views. I have specified the .textSelection(.enabled) modifier for the text views. Adding this modifier causes a "copy" option to appear on long press, but it doesn't enable the visible selection of text, nor does it provide the "Speak" menu item that UIKit allows on text selection. Is the "Speak Selection" accessibility feature broken for SwiftUI Text views? I've found that there's another accessibility feature that does work (enabling the Speech Controller button for "Speak Screen"). Do I need to tell my users that Apple is deprecating the "Speak Selection" accessibility feature, and that they need to use the Speech Controller instead? Or is there something else I can do to my SwiftUI to get that feature to work?

VoiceOver for Accessibility Labels with Localization
Hello! I'm adding VoiceOver support for my app, but I'm having an issue where my accessibility value is not being spoken. I have made a helper class that creates an NSString from a double and converts it to the user's region currency. CurrencyFormatter.m + (NSString *) localizedCurrencyStringFromDouble: (double) value { NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init]; formatter.numberStyle = NSNumberFormatterCurrencyStyle; formatter.locale = [NSLocale currentLocale]; NSString *currencyString = [formatter stringFromNumber: @(value)]; [formatter release]; return currencyString; } View Contoller self.checkTotalLabel.accessibilityLabel = NSLocalizedString(@"Total Amount", @"Accessibility Label for Total"); self.checkTotalLabel.accessibilityValue = [CurrencyFormatter localizedCurrencyStringFromDouble: total]; I'm confused on whether the value should go into the accessibility label or not. When the currency is just USD and the language is English, it's a simple fix. But when the currency needs to be converted, I'm not sure where to go from here. If anyone has any guidance, it would help me a lot! Thank you!

Speak Screen gesture not working
I am testing the accessibility feature available in the Settings app called "Speak Screen". The help text in the Setting app states that swiping down with two fingers will cause the screen content to be spoken. However, I've been unable to get this feature to work. Every time I try the double finger swipe down, it behaves the same as the single finger swipe down gesture. Usually this manifests as making scroll views bounce. I've tried toggling the feature on and off, turning off Reachability, and rebooting my phone, but I can't get the speak screen gesture to work. If I access the speak screen feature from the "Speech Controller" button, then the screens content is spoken, as expected, so I know the feature is enabled. It's just the gesture that doesn't work. Is there something else I need to do to get this gesture to work? I don't want to tell my users to turn this feature on if I can't verify that the gesture will work with my app.

SwiftUI PhotosPicker accessibility issue
iOS 18.3.1, iPhone 16 Pro. I pick photos using connected physical keyboard from the user's photo library using: .photosPicker(isPresented: $viewModel.isImagePickerPresented, selection: $viewModel.selectedImageItem, matching: .images) When picker appears, accessibility focus is moved to "dynamic Island" instead of cancel button. There is no possibility to navigate by keyboard in photos picker view without tapping on this view and move focus to this view manually . I noticed the same behavior in Notes app.

accessibilityRespondsToUserInteraction return true on Simulator but false on device
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)

Please consider having Name Recognition in a shortcut automation
Request: Name Recognition → Shortcut for SOS Flashlight + Vibration Right now, iOS Name Recognition works, but all I can do is flash the tiny notification light. It would be much more useful if Name Recognition could trigger a Shortcut. That way, I could set it to flash the flashlight in an SOS pattern and vibrate, making the alert impossible to miss. I tried using Custom Alarm, but it won’t let me record my spoken name, so it doesn’t really solve the problem. If Apple allowed Name Recognition to trigger Shortcuts — or expanded “Custom” to support names/words — this would open up far more practical, real-world alerts.

Subpath for access to Silence Unknown Callers
Hi, Our app has a section where, we show to users how to activate "Silence Unknown Callers", because is a crucial feature for our app. But, we saw that 30% of users drop the process here, because we can't open directly that setting option in phone app. We are using this url scheme to open phone settings in iOS 18: if let url = URL(string: "App-prefs:com.apple.mobilephone") { UIApplication.shared.open(url) } But, we don't see other way to open directly the path "silence", like in iOS 17, with this url scheme: prefs:root=Phone&path=SILENCE_CALLS So, do you know if is possible open that option directly? We want to improve our accessibility. Thank you!

HID Braille keyboard support on iPhone 6S
Hello, I am working on a Braille keyboard by using HID approach. Current the device works with iPhone 11 and SE3. However, when tested in iPhone 6s with iOS 15, although the device can be connected and recognized as Braille device in VoiceOver screen, the phone shows no response to key press report. Would there be any requirement at points such as HID descriptor for iPhone 6s support on Braille device? If iPhone 6s does not support such devices, what is the minimum system requirements? Thank you!
