XProtect makes app hang when running an AppleScript
I now had the second user with 26.2. complaining about a hang in my app. The hang occurs when the first AppleScript for Mail is run.

Unable to install Metal toolchain through Xcode Cloud
We build TestFlight/App Store builds of our app through Xcode Cloud. Our app uses Metal shaders so we install the Metal toolchain through a ci_pre_xcodebuild.sh script which simply runs: xcodebuild -downloadComponent metalToolchain in our Xcode Cloud builds. This has been working well for us for the last 6 months or so, but since yesterday (March 5) we have been seeing consistent failures when running this script in our Xcode Cloud builds: Beginning asset download... 2026-03-06 04:14:34.727 xcodebuild[13315:58523] Writing error result bundle to /var/folders/6h/_32gb9js77g6c54h3q7g6q1h0000gn/T/ResultBundle_2026-06-03_04-14-0034.xcresult xcodebuild: error: Failed fetching catalog for assetType (com.apple.MobileAsset.MetalToolchain), serverParameters ({ RequestedBuild = 17C7003j; }) Prior to Mar 5 it looks like the toolchain image which was being downloaded/installed was 17C519 but this has now changed to 17C7003j.

Korean IME forces Smart Quotes, ignoring UITextInputTraits and OS Settings
There is a long-standing, structural issue with the iPadOS Korean IME when using a hardware keyboard. The IME forcibly intercepts the (quote) keydown event and injects Unicode smart/curved quotes (“ or ”) directly into the text field. This hardcoded behavior ignores both: User Settings: The global Smart Punctuation toggle in [Settings > General > Keyboard] is completely ignored. Developer APIs: Setting UITextInputTraits.smartQuotesType = .no on a UITextView or UITextField has absolutely no effect when the Korean keyboard is active. Steps to Reproduce: Set smartQuotesType = .no on a standard UITextView. Connect a hardware keyboard. Switch input language to English -> Press the quote key. (Result: ASCII straight quote - Correct behavior) Switch input language to Korean -> Press the quote key. (Result: Unicode curved quote “ - Incorrect behavior) Impact on Developers & Users: Because the OS IME forcefully injects the curved Unicode character before the app can process the raw key event

Reply to Broken autocomplete in Xcode 26
Thank you for providing the bug number. The videos demonstrate the issue in your system. The crucial aspect is to reproduce it on a new machine without any key customization. As the tab key is used as the default autocomplete key, overriding or having shortcuts could make a difference. In previous versions, when the autocomplete popup displayed multiple suggestions with the same prefix, pressing the tab key would insert only the prefix. I recommend checking Settings > Key Bindings for several bindings related to code completion. Additionally, it is important to be aware of all changes on your system, which is why I requested the sysdiagnose previously. In any case, the team has now identified the bug and can investigate its cause. However, I do not see any other related bugs, so I am confident that this issue is specific to your system.

How to upload large videos with PHAssetResourceUploadJobChangeRequest?
I'm implementing a PHBackgroundResourceUploadExtension to back up photos and videos from the user's library to our cloud storage service. Our existing upload infrastructure uses chunked uploads for large files (splitting videos into smaller byte ranges and uploading each chunk separately). This approach: Allows resumable uploads if interrupted Stays within server-side request size limits Provides granular progress tracking Looking at the PHAssetResourceUploadJobChangeRequest.createJob(destination:resource:) API, I don't see a way to specify byte ranges or create multiple jobs for chunks of the same resource. Questions: Does the system handle large files (1GB+) automatically under the hood, or is there a recommended maximum file size for a single upload job? Is there a supported pattern for chunked/resumable uploads, or should the destination URL endpoint handle the entire file in one request? If our server requires chunked uploads (e.g., BITS protocol with CreateSession → Fragment → CloseSes

Recurring FigXPCUtilities / FigCaptureSourceRemote err=-17281 logs when using AVCaptureVideoDataOutput on iOS 26.x
Hi everyone, I’m seeing recurring internal AVFoundation camera logs on iOS 26.2 and I’m trying to understand whether this is expected behavior or a regression in the capture pipeline. These logs appear shortly after starting an AVCaptureSession, while video frames are being delivered, and also when the camera is stopped or the capture session is torn down. <<<< FigXPCUtilities >>>> signalled err=-17281 at <>:302 <<<< FigCaptureSourceRemote >>>> Fig assert: err == 0 at bail (FigCaptureSourceRemote.m:569) - (err=-17281) Even in this clean, minimal setup, the same logs appear on iOS 26.2 The exact same logic did not produce these logs on iOS 18.x.

Reply to Recurring FigXPCUtilities / FigCaptureSourceRemote err=-17281 logs when using AVCaptureVideoDataOutput on iOS 26.x
Thanks for this interesting post! I'm not an expert on that field nor that API. Hope one of the engineers on that team can jump into this thread for better info. These specific FigXPCUtilities and FigCaptureSourceRemote logs are almost certainly benign internal framework noise rather than a regression or a flaw in your capture pipeline. Looking up the err=-17281 is a CoreMedia error code that, without knowing here, typically points to a minor XPC synchronization hiccup, a port invalidation, or an asynchronous state mismatch during the setup or teardown of the capture session? I believe this logs are for information only and should be removed. Code paths that silently recovered in older iOS versions often have their log levels elevated in newer releases (or beta releases), resulting in console spam. If your AVCaptureVideoDataOutputSampleBufferDelegate is successfully receiving CMSampleBuffer frames and your preview layer is rendering smoothly. You can safely ignore these logs.

Reply to UIDocumentPickerViewController allows to select file declared in Info.plist document types even when restricting to folder UTI
Thank you for filing FB22254960 . When your app declares support for public.text in CFBundleDocumentTypes, you're telling the system that your app can open text documents. The document picker respects your declaration and shows both the content types you explicitly request folder and the types your app supports.
