Apple updates Xcode to version 26.1.1 with smarter AI coding tools and key performance fixes

Apple has released Xcode 26.1.1, delivering a round of bug fixes and performance upgrades to its integrated development environment, including refinements to the AI-powered Coding Assistant introduced earlier this year. The update also introduces enhanced system tools for connected devices and improved Swift support.

Xcode 26.1.1 adds compatibility for Swift 6.2.1 and addresses several issues affecting the new AI-assisted coding workflow. Developers using the built-in ChatGPT integration had reported performance slowdowns and inconsistent tool responses when applying code changes. Apple says these problems have now been resolved, resulting in a smoother and more stable experience when using the assistant for code generation, editing, and debugging.

The update also improves memory management in large projects, reducing the overhead caused by repositories with extensive git histories. Another fix corrects an error where the Coding Assistant’s “find text in file” function produced incorrect line numbers, which had been causing failed text replacements during code refactoring. Apple further addressed a bug that could temporarily disable coding tools within the source editor and menus.

Beyond the AI enhancements, Xcode 26.1.1 brings fixes across several core areas, including CallKit, Instruments, Interface Builder, Localization, Swift Packages, Swift Testing, and Xcode Cloud. It also resolves an indexing issue that had been preventing background tasks from completing in certain projects.
