Xcode 26.6 landed quietly — no announcement post, no feature blog, just a build number bump to 17F113 and a pointer to the SDK release notes at developer.apple.com. App Store Connect got a companion tooling update the same day, which is standard practice when Xcode ships. This is the kind of release that exists to close out the 26.6 beta cycle that started June 15. The release notes link suggests SDK-level fixes rather than IDE features. Worth pulling down if you're running into simulator or build-system edge cases, but nothing here changes your project setup or demands urgent action.
