It's absolutely crazy to me that @swiftlang Package Traits were proposed over a year ago and publicly released months ago and no version of Xcode has ever supported actually using them, and #Xcode26 is currently on track to also ship without support.
Want to use Google Gemini in #Xcode26 beta? You can – the key is URL rewriting, but it's super-simple to do using the Proxyman tool. I'll show you how:

App builds in debug and runs
Snapshots pass
Unit tests mostly pass
Release build crashes the compiler
Not a bad first week at all! Kudos to Apple engineers
Everyone's favourite Developer Technical Support @ #Apple, @justkwin, described the current situation of logging in to an Apple Account and/or issueing provisioning profiles inside a #macOS VM, and provided some options. https://developer.apple.com/forums/thread/787500?answerId=843094022#843094022
It still doesn't fully work, but at least now we know what's up. That's good!
#iOSDev PSA: new #Xcode26 projects default to Main Actor isolation, which can lead to errors with Sendable types 
Possible Fixes:
1: Change default isolation
2: Mark type as nonisolated
3: Ignore #SwiftConcurrency 
@mattiem has a great post on default isolation: https://www.massicotte.org/default-isolation-swift-6_2
Quite frankly, if I hadn't read your post before, I probably would've taken a lot longer to figure out why the heck the type in question was MainActor isolated to begin with - thanks Matt! 
Use any OpenAI-compatible LLM provider in Xcode 26, even without Apple Intelligence: In which I build upon @simonbs.dev's work and look into adding #OpenAI and #OpenRouter to #Xcode26.

Apple implemented a feature I had requested in #Xcode26. So sending feedback does actually have an effect on the decision the teams make!
So don't forget to share your feedback in the coming weeks. Bugs might get fixed right away, and feature requests shipped the next year (like mine)!
Xcode 26 : c’est pas Cursor, mais c’est pas mal http://dlvr.it/TLGVD5 #Xcode26 #Apple
If your project crashes in #Xcode26 upon opening, the official fix is to find the "UserInterfaceState.xcuserstate" file and delete it (as stated in the release notes).
Right-click your ".xcodeproj", choose "Show Package Contents". Do the same for "project.xcworkspace". Now delete the entire "xcuserdata" folder which contains the incompatible ".xcuserstate" file. Done! 
Sadly, Apple's auto complete is still not good. I got it to fail on a simple case that copilot has been nailing for months.
ChatGPT got it from a conversational aspect, and even edited a closed file when I tacked onto the same conversation.
I like that it shows an Apple Intelligence colored change bar in the gutter. #wwdc #xcode26
Woah. Xcode 26 can now use AI to generate localized strings for you on the fly. 
A horror story in two parts #Xcode26 #CodeIntelligence
Indie #iOSDevs let's all share what our apps look like when built for #iOS26 with #Xcode26 
Out of the box screenshots only - tweaking is cheating 
@zenitizer needs a lot of work to blend in and take advantage of #LiquidGlass but at least it compiles and is usable 
#Xcode26 beta 1 is out!
The SDKs in #Xcode 26.0 beta 1 (build 17A5241e, requires macOS 15.4+) are:
macOS 26.0 (25A5279m)
iOS 26.0 (23A5260k)
watchOS 26.0 (23R5280j)
tvOS 26.0 (23J5279j)
visionOS 26.0 (23M5263k)
Clang 17.0.0 (1700.3.9.908)
Swift 6.2 (6.2.0.9.909)
The https://xcodereleases.com website, API, and RSS feed have all been updated with the latest information.
Oh developers can opt out of liquid glass when building with #Xcode26?
I wonder what the adoption rate will be by the end of the year 
Personally, I'm definitely planning to adopt it and lean into it for @zenitizer
