Xcode 26
Xcode 26 includes Swift 6.2 and SDKs for iOS 26, iPadOS 26, tvOS 26, watchOS 26, macOS Tahoe 26, and visionOS 26. The Xcode 26 release supports on-device debugging in iOS 16 and later, tvOS 16 and later, watchOS 8 and later, and visionOS. Xcode 26 requires a Mac running macOS Sequoia 15.6 or later.
Enhance your development workflow with coding intelligence features that help you write code, generate tests and documentation, fix errors, refactor existing implementations, and navigate codebases. Xcode has integrated support for ChatGPT and Claude user accounts. You can also use your API key for any model provider that supports the Chat Completions API, or download and run a local model on Macs with Apple silicon.
The build number is the same as for the release candidate, though I found that the .xip files differ slightly in size and content.

@Brendan Ah, you’re right. I must have been comparing the first two lines, which are both the release version (since they have a separate Apple Silicon build now).
I tried out the integrated AI ... of course AppKit being such a niche framework the answer to my question was some heavy hallucination. Nothing new here.
But then the AI proceeded to apply its hallucinations to my code base. I have no idea if I pressed the wrong key or clicked something. And luckily I didn't have any uncommitted code changes so reverting it was pretty easy.
But imagine this happens when you actually have some uncommitted work ...
Also the new sidebar style makes my app look like something from the 2003 Linux desktop days and there's no quick way to "just use the old style".
I'm back to Xcode 16 for now.
@Leon You can use https://developer.apple.com/documentation/BundleResources/Information-Property-List/UIDesignRequiresCompatibility to have your app appear in the old style for the time being.
I updated to Tahoe yesterday. The App Store informs me that there's an update to Xcode available. I've tried to update it multiple times, but it always eventually fails with ""Xcode" could not be installed. Please try again later." ¯\_(ツ)_/¯
@Doodpants, I've been on Xcode beta on one laptop since June. It went through 7 betas, and is now at RC. My other laptop? Just finished updating it successfully through MAS. It took almost a day after the OS '26 releases to show up, but it went with no issues.
BTW, love your name! (Meant sincerely.)
My first experience with Xcode 26 was trying to create an Objective-C mac project. It proceeded to create a project with the correct source files saved to disk, but missing any UI files, and with non-existent Swift files added to the project. So basically the project was totally broken.
I shan't be using it.
