New Xcode update released

Apple has released Xcode 27.2, the latest version of its development tools, on the Mac App Store. This update introduces support for testing touch interactions on the new MacBook Pro with PROLED XDR screens.

Touch testing on new displays

The new version includes features that allow developers to test touch interactions using their fingers directly on the MacBook Pro's display during development. This capability is designed to help developers create and refine applications that use touch input more effectively.

AI integration and file format change

The update brings several improvements aimed at developers, including enhancements related to artificial intelligence. Xcode 27.2 introduces a tool that enables AI agents to identify which parts of the code have been tested during the last tests, allowing them to focus on areas that have not yet been tested.

New JSON format for projects

Additionally, the update introduces a new JSON format for Xcode projects, which is more readable and easier to modify than the previous PLIST format. This format is expected to facilitate the work of AI agents handling project files.

Enhancements to preview and testing tools

Xcode 27.2 also includes improvements to the Previews and Device Hub tools. The Previews tool allows developers to preview interfaces during development, while the Device Hub tool now offers several practical functions for testing, such as slowing down animations, simulating a device shake, and artificially causing a memory pressure situation.

New SDKs and bug fixes

The update includes Swift 6.4 and the 27.2 SDKs for iOS, iPadOS, macOS, and watchOS. Xcode 27.2 promises bug fixes and improved stability. The software remains free and requires an Apple Silicon Mac running at least macOS 26.6.
