Recently, Apple officially released the Xcode 26.1.1 version, bringing a series of exciting updates and improvements. This version not only supports Swift 6.2.1 but also optimizes several features that developers care about. According to the latest report from the tech media 9to5Mac, this update mainly focuses on fixing bugs and improving the performance of the "Coding Intelligence" AI coding assistant.

Firstly, this update significantly improves the memory usage efficiency of the "coding assistant," especially when handling large Git projects, where previous common lag issues have been significantly improved. In addition, Apple has fixed cases where the coding tool might fail in certain specific situations, ensuring a smoother experience for developers while coding.

Another important update is that the text search tool within files can now accurately return the correct line numbers, greatly reducing the trouble caused by incorrect information. The feature that developers are most interested in is the optimized interaction performance with ChatGPT. This update fixes the lag issue that may occur when applying code changes, making the AI-assisted programming experience smoother.

In addition to these improvements in AI features, Xcode 26.1.1 also fixes multiple issues that affect development efficiency. For example, the stubborn bug that previously prevented some projects from completing background indexing has been successfully fixed. These improvements provide developers with a more reliable and efficient working environment.

Notably, this update introduces a new feature for developers. By running specific commands in the terminal, developers can now easily collect system diagnostic logs from connected iPhones or other Apple devices. This new feature will greatly simplify the debugging and diagnostic process for device issues, allowing developers to quickly identify and resolve hardware or system-level problems.

The release of the Xcode 26.1.1 version provides developers with a series of practical updates and functional improvements, especially in the areas of AI coding assistants and device diagnostic tools, making developers' work more efficient.
