 ## How it works
 
-- A darwin SDK is generated from a user provided copy of Xcode 16.3 (extracted with [unxip-rs](https://github.com/nab138/unxip-rs)) and darwin tools from [darwin-tools-linux-llvm](https://github.com/xtool-org/darwin-tools-linux-llvm)
+- A darwin SDK is generated from a user provided copy of Xcode 26 (extracted with [unxip-rs](https://github.com/nab138/unxip-rs)) and darwin tools from [darwin-tools-linux-llvm](https://github.com/xtool-org/darwin-tools-linux-llvm)
 - Swift uses the darwin SDK to build an executable which is packaged into an .app bundle.
 - The code to sign and install apps onto a device has been removed from CrossCode's source and moved to a standalone package, [isideload](https://github.com/nab138/isideload). It was built on a lot of other libraries, so check out its README for more info.
