Suddenly, automatic signing has stopped working across all our apps (even on different developer IDs), we see this:Automatic Signing FialedXcode failed to provision this target. Please file a bug report at <https://feedbackassistant.apple.com> and include the Update Signing report from the Report navigator.Signing certificate Apple Development: XXXXX (XXXXX), serial number XXXXX, is not valid for code signing. It may have been revoked or expired.Anyone else experiencing the same? I've tried doing everything from deleting the derived folder, to trying to reset and create new certificates to trying different versions of Xcode. Everything fails and I get a prolonged Waiting to repair message first and then this.

What happened to CMD-Option-Click in Xcode 26 for opening a symbol in a new editor split pane? This was one of the most usefull shortcuts. Xcode 26 is a pain to use without it.

This post documents an issue I reported in feedback FB19610114 and see if anyone knows of a workaround. Here is a copy of the feedback. Short version Manipulation (SwiftUI OR RealityKit) fails to translate entities after changing rooms. By changing rooms, I mean a human wearing an Apple Vision Pro leaving one room and entering another room. Once this issue occurs, it impacts all apps that use these features. A device restart is the only solution I have to fix it. Feedback FB19610114 This is an odd one. I'm using the new Manipulation Component in visionOS 26. Most of the time this works well. Sometime it stops working and when it does the only way to get it working again is to reboot the headset. When this happens, I can continue to rotate and scale items, but translation no longer works. It is as if the item is stuck to a fixed point in the parent scene (window, volume, etc). When this bug occurs, it affects every app across the entire operating system that is using manipulation, including the RealityKit comp

Foundation Models framework worked perfectly on macOS 26 Beta 2, but starting from Beta 3 and continuing through Beta 6 (latest), I get dyld symbol errors even with the exact code from Apple's documentation.

I've been getting intermittent failures on Xcode code compiling my app on multiple platforms because it fails to compile a metal shader. The Metal Toolchain was not installed and could not compile the Metal source files. Download the Metal Toolchain from Xcode > Settings > Components and try again. Sometimes if I re-run it, it works fine. Then I'll run it again, and it will fail. If you tell me to file a feedback, please tell me what information would be useful and actionable, because this is all I have.

(Using macOS 26 Beta 9 and Xcode 26 Beta 7) I am trying to support basic onDrop from a source app to my app. I am trying to get the closest source representation of a drag-and-drop, e.g. a JPEG file being dropped into my app shouldn't be converted, but stored as a JPEG in Data. Otherwise, everything gets converted into TIFFs and modern iPhone photos get huge. I also try to be a good app, and provide asynchronous support. Alas, I've been running around for days now, where I can now support Drag-and-Drop from the Finder, from uncached iCloud files with Progress bar, but so far, drag and dropping from Safari eludes me. My code is as follows for the onDrop support: Image(nsImage: data.image).onDrop(of: Self.supportedDropItemUTIs, delegate: self) The UTIs are as follows: public static let supportedDropItemUTIs: [UTType] = [ .image, .heif, .rawImage, .png, .tiff, .svg, .heic, .jpegxl, .bmp, .gif, .jpeg, .webP, ] Finally, the code is as follows: public func performDrop(info: DropInfo) -> Bool { let itemP
