Reply to Availability for BLE background scanning on watchOS whilst dimmed
Bluetooth scanning in the background on watchOS is not only throttled, but works in a whole different manner than on iOS, and has its own additional limitations. You might want to take a look at the sample Interacting with Bluetooth peripherals during background app refresh and also refer to the WWDC Session Get timely alerts from Bluetooth devices on watchOS to understand who BLE background scanning works on watchOS.

Availability for BLE background scanning on watchOS whilst dimmed
I am trying to find out about the availability of BLE scanning for advertisements when a watchOS app (on watchOS 26.4 with CoreBluetooth) which starts running a HKWorkoutSession becomes dimmed, ie. due to the user lowering their arm. From my understanding there is still availability for ongoing scanning whilst in the dimmed mode. If this is correct, what settings are required (e.g. using background capability for 'Workout Processing', 'bluetooth-central', etc), and does scanning whilst in background mode limit to requiring service uuids in scanForPeripherals? Also if scanning is throttled, is there an 'estimated' inter scan time? Thanks

iOS 26 - S/MIME Encryption / Certificates
Hi everyone. Since the update to iOS 26, we are no longer able to tap the person's name and view the certificate of a signed email and choose to install the certificate or remove it. This has always worked just fine but seems to be broken on iOS 26 and I have verified that it does not work on iOS 26.1 beta as well. The part that is strange is it does work just fine on an iPad running iPad OS 26. This makes it impossible to send encrypted emails to someone via the mail app on an iPhone. I have found a temporary workaround which is to install Outlook for iOS and install the certificates through that app which then allows me to send encrypted emails via Outlook. This appears to be a bug just with the iPhone as I have also seen a few other people online talking about the same problem. Has anyone found a solution to this?

Reply to Tahoe 26.4 breaks custom paths with NetFSMountURLSync?
That makes sense and is how I interpreted it. For now, I had to disable it though so users do not run into issues. Or better set: I do not get bombarded with support questions 😊 Fair enough! Feedback number: FB22380104 Perfect, thank you. FYI, it's likely that you'll be notified that this bug is a duplicate in the next few days. Many developers interpret this as meaning that their bug was unnecessary and is being ignored“; however, that's a misunderstanding of what's going on, particularly when someone at Apple (like me) asks for a bug. As you might imagine, the combination of our own testing and the volume of users means that it's pretty likely that SOMEONE has filed a bug before you. So, yes, that means that many bugs are effectively telling us about an issue we already knew about. However, what gets missed there is that the reason to file a bug isn't just to tell us about the problem“; it's also about documenting impact so we can properly prioritize work and scheduling. __ Kevin

Tahoe 26.4 breaks custom paths with NetFSMountURLSync?
Just wondering if anyone ran into this issue. I use NetFSMountURLSync for my application with which I allow the user to use a custom path as a mount point (instead of /Volumes). This has worked just fine for at least a decade now, but ... since the Tahoe 26.4 update mounting to a custom path only generates errors. Note: Mounting to /Volumes works correctly (mountpoint = NIL). Since I'm unaware of any changes; is this a bug introduced by Tahoe 26.4, or should I be using a different function to mount a network share?

Reply to iOS 12.5.8 fails to bootstrap app
The same for Organic Maps: internal CI TestFlight build on March 25 works on iOS 12 device, the same binary with a few string resource changes, built on March 26 does not work. Built with the frozen version of Xcode 26.2. That implies some kind of Apple involvement when builds are uploaded.

Reply to Regression / Feature Request: Jumbo Frame (MTU 9000) support missing in AppleUserECM for RTL8156 2.5G USB adapters
Because we are forced through MTU 1500, we are incurring significant performance penalties: Have you filed a bug on this and, if so, what's the bug number? Is there an undocumented boot-arg or network sysctl parameter that permits overriding the AppleUserECM 1500 MTU hard-limit for 2.5G USB adapters on Apple Silicon? No, not that I'm aware of. Are there any roadmap plans from the DriverKit/Networking team to re-enable standard Jumbo Frame negotiation for RTL8156 hardware using the generic ECM driver? In general, Apple's future plans aren't really something I can discuss. Does Apple grant NetworkingDriverKit Entitlements to independent developers specifically for the purpose of writing custom hardware overrides to patch missing MTU features in the default ECM stack? Approval here would primarily depend on the hardware you’re asking to create a DEXT for and, in particular, how broad the request configuration is[1]. However, we do approve developers for DriverKit entitlements who are not

Left-flick and right-flick gestures with VoiceOver and UIAccessibilityReadingContent
Hi, I have an app that displays lines of text, that I want to make accessible with VoiceOver. It's based on a UITextView. I have implemented the UIAccessibilityReadingContent protocol, following the instructions in https://developer.apple.com/videos/play/wwdc2019/248 and now users can see the screen line by line, by moving their fingers on the screen. That works fine. However, users would also like to be able to use left-flick and right-flick to move to the previous or next line on the screen, and I haven't been able to make this work. I can see that left-flick triggers accessibilityPreviousTextNavigationElement and right-flick triggers accessibilityNextTextNavigationElement, but I don't understand what these variables should be.

Reply to Left-flick and right-flick gestures with VoiceOver and UIAccessibilityReadingContent
accessibilityPreviousTextNavigationElement and accessibilityNextTextNavigationElement are not meant to represent previous/next line inside a single UITextView; they should point to another accessibility element, not a line number or string. In your case, UIAccessibilityReadingContent supports line-by-line touch exploration, but left/right swipe still moves between accessibility elements, not internal lines of one text view. That’s why touch works but swipe does not. The correct approach is to keep the UITextView for display and expose each visible line as its own UIAccessibilityElement, with accessibilityLabel set to the line text and accessibilityFrameInContainerSpace set to that line’s frame. Once the lines are separate accessibility elements and returned in order, VoiceOver will naturally use right swipe for the next line and left swipe for the previous line. You can optionally link neighboring lines with accessibilityNextTextNavigationElement and accessibilityPreviousTe

Reply to App crashes on launch for iOS 12 users after App Store release (Xcode 16.4) — BKSProcessErrorDomain bootstrap-failed
Thanks for the clarification. However, this is quite concerning from a developer and user-impact perspective. This app version was: • successfully built and uploaded with Xcode 16.4 • accepted in App Review • distributed through the App Store Despite having a deployment target of iOS 12, the build is now crashing on launch for all iOS 12 users, without any prior warning during submission or review. As a result, a previously working user base on iOS 12 has effectively lost access to the app overnight after updating, which is a significant regression in functionality. If iOS 15 is now a strict requirement for App Store distribution, it would be much safer for developers if: • the upload was rejected at submission time, or • a clear warning was shown before release rather than allowing distribution of a build that cannot run on supported devices declared in the app’s deployment target. Is there any recommended way to: Restore functionality for existi

App targeting iOS 12 crashes on launch when installed via TestFlight but works via Ad Hoc and Xcode direct install
My app targets iOS 12.0 and crashes immediately on launch when installed via TestFlight on an iPad running iOS 12.x. The same archive works perfectly when installed via Ad Hoc distribution or directly from Xcode. This is a regression — the exact same source code, compiled with the same Xcode version, was successfully distributed via TestFlight and the App Store last month (March 2026) without issues. No changes were made to the code, Xcode version, or signing configuration. Steps to reproduce: Archive an app with IPHONEOS_DEPLOYMENT_TARGET = 12.0 using Xcode 16.4 Upload to App Store Connect Install via TestFlight on an iPad running iOS 12.x App crashes immediately on launch (pre-main, no crash log generated) Expected: App launches normally (as it did last month) Actual: App is killed immediately, process exits with reason: (none) Console.app shows the process never transitions from xpcproxy to the actua

Reply to ‌Xcode26-built apps cannot run on iPhone 6 or earlier devices‌
The same situation with our app, crashes on iOS 12 on startup if the app was built and processed by TestFlight after March 25. More than 400 active users of iOS 12 won't get the update if the issue is not resolved :(

I am still experiencing this as of today. No way to store the certificates -> No valid certificates found for any of the recipients -> unencrypted sadness.

Distribution through the App Store requires a minimum deployment target of iOS 15. For future reference, you can find this information listed on the Xcode Support webpage.
