The Proliferation of DarkSword: iOS Exploit Chain Adopted by Multiple Threat Actors
Dear Team, Can you please check and confirm for this security Google Threat Intelligence Group (GTIG) has identified a new iOS full-chain exploit that leveraged multiple zero-day vulnerabilities to fully compromise devices. Based on toolmarks in recovered payloads, we believe the exploit chain to be called DarkSword. Since at least November 2025, GTIG has observed multiple commercial surveillance vendors and suspected state-sponsored actors utilizing DarkSword in distinct campaigns. These threat actors have deployed the exploit chain against targets in Saudi Arabia, Turkey, Malaysia, and Ukraine. https://cloud.google.com/blog/topics/threat-intelligence/darksword-ios-exploit-chain?hl=en

EXC_BAD_ACCESS on WebCore::ElementContext::isSameElement at select element
According to our crash analytics, our application crashes while a context menu is closed (after being opened on a web view). This crash takes place on iOS 26+ only. Seems like WebCore::ElementContext::isSameElement is called after ElementContext has been destroyed, so it's a kind of use-after-free issue. Can you please help with a fix or at least workaround for this issue? What's your opinion for bug localization (application or framework)?

Inconsistency exception regarding context menu on web view
According to our crash analytics, our application crashes while a context menu is opened on a web view. This crash takes place on iOS 26+ only. The messages states that a web view is no longer inside active window hierarchy, however we doesn't modify web view instance's parent anyhow while the context menu is opened.

App Transfer Completed but Extension App IDs Missing and Cannot Be Recreated
Hello, We recently transferred our iOS app to a new Apple Developer account, and we are experiencing an issue that is currently blocking our release. The transfer of the main app appears to have completed successfully: The app is visible in App Store Connect under the recipient account The main bundle ID is available However, the App IDs for our extensions are missing from the recipient account in Certificates, Identifiers & Profiles. Affected bundle identifiers: com.finanfut.finanfut.NotificationService com.finanfut.finanfut.NotificationContentExtension The issue is: These App IDs do NOT appear in the recipient account We are NOT able to create them manually Apple returns: “The app identifier is not available” As a result: Xcode cannot generate provisioning profiles We get errors like: No profiles for 'com.finanfut.finanfut.NotificationContentExtension' were found We are blocked from archiving and distributing the app It seems that the App IDs are still reserved in Apple's backend but were not p

Reply to Clipboard issues with simulators
Hi. I am facing this issue as well. Tried this out and I am getting this as a response: xcrun simctl spawn booted launchctl kickstart -k system/com.apple.pboard Could not find service com.apple.pboard in domain for system Upon further investigation, if you copy something within the simulator and try to paste it, it works within the context of the simulator. However, when u try to paste text you copied from the mac it doesn't get carried forward to the simulator and instead pastes what you copied earlier on the simulator. I have tried the 'Automatically Sync Pasteboard' option under Edit in simulator as well but to no avail. If i run the terminal commands as well to paste from the simulator's uuid like the following: xcrun simctl pbpaste 99D03E66-6DA6-40AC-8E9F-98874D8F6464 xcrun simctl pbcopy 99D03E66-6DA6-40AC-8E9F-98874D8F6464 simulator copy It would only paste what I wrote within the simulator. This happens on iOS 26.4 simulators after updating to xCode 26.4

Reply to Xcode 26.3 not rendering Unicode/Emoji in Simulator or Canvas
Thank you to Albert for his post above. With regard to the post, for me following the instructions to reinstall the iOS 26.3 and simulator did not work as it reinstalled the same simulator with the same issue. However I am pleased to report that I tested the Xcode 26.4 RC with the accompanying simulator and it does resolve this issue. I see that a final iOS 26.4 has been released, so the matching final Xcode is due very shortly to put this behind us. Cheers.

RealityView AR - anchored to the screen not the floor
This started out as a plea for help, but in preparing this post I discovered the root cause. I'm posting it as a lesson learned in hopes it will help someone. I've spent a good chunk of March trying to get AR-mode working again in my unreleased game. I had it working with SceneKit and ARView 5 years ago, but since 2024 I've been converting the game to use RealityKit and RealityView on iOS, macOS, visionOS, and tvOS. I've been having no joy getting AR mode to work on iOS. I get the pass-through device video but the game content isn't anchored to the floor but rather anchored to the screen. I made a simple project with just a simple shape in the middle of a RealityView and an overlay with a SwiftUI toggle to go in and out of AR-mode. At first, my simple project worked, and I couldn't figure out what was different in the logic. Both projects used the same logic: func transitionToXR(_ content: inout RealityViewCameraContent) { content.remove(gameBoard.rootEntity) content.add(xrAnchor) content.ca

Reply to App Clips not working
Thanks for the post, in this page you'll find a sample for AppClips as well as the first note will provide you the 101 of App Clips. I always recommend developers to go over all those videos and documentation liked on that note. Then download the app, look at every single configuration from that app including the Clip target! https://developer.apple.com/documentation/appclip/fruta-building-a-feature-rich-app-with-swiftui In my opinion and without going deep in your solution, the reason your AASA endpoint is never getting called when you scan the QR code is due to a common misconception about how iOS handles App Clips and Universal Links, the iOS device does not fetch the AASA file at the moment you scan a QR code. Downloads the file at app installation time and there is also a delay. When you scan a QR code, iOS checks its local cache and Apple's CDN records to see if that URL is registered to an App Clip. If Apple's CDN hasn't validated your AASA file, or if the TestFlight configur

Reply to Matter OTA on TestNet: HomePod always replies "UpdateNotAvailable" (Device is already CSA Certified)
When did you install the TestNet Profile and are you sure it's still valid? The previous profile expired in early February, so you'll need to have updated it recently. Note that you need to install the profile on all the devices involved and that a mixed configuration where the iOS device has the current profile but the HomeHub does not will very likely generate behavior similar to what you're seeing. Here is exactly what is happening: Our device successfully sends a QueryImage command to the HomePod. The HomePod receives it, but immediately fires back a QueryImageResponse that essentially means UpdateNotAvailable, forcing the device into an 86400-second sleep timeout. Chapter 4 of the Apple Matter OTA - User Guide (r6) outlines a number of specific recommendations and guidelines. Are you following all those guidelines, particularly around MinApplicableSoftwareVersion and MaxApplicableSoftwareVersion? Many of our recommendations in these specifications are best understood as requirements, not suggest

Reply to Xcode 26.3 not rendering Unicode/Emoji in Simulator or Canvas
Xcode 26.4 final is available and has resolved this issue. The iOS 26.4 simulator does correctly display emoji/unicode. Install Xcode 26.4 from the Mac App Store or similar to resolve this issue.

Reply to Fatal error on rollback after delete
Thanks for filing the feedback report (FB22325366). Yeah, that does look like an issue on the framework side. I can reproduce the crash without the need of adding a second relationship with Xcode 26.4 (17E192) + iOS 26.4 (23E244) Simulator. Best, —— Ziqiao Chen  Worldwide Developer Relations.
