Installation

CrossCode is currently in alpha. Expect bugs!

Download the latest build for your platform from releases.

Check out the Getting Started section of the wiki. Also, see Troubleshooting and FAQ

Future plans

The app is currently functional but does not have all the features it should. You can see a tentative plan for the future on trello

Please note that I am one person, so development may be slow. If you want to help, PRs welcome!

How it works

• A darwin SDK is generated from a user provided copy of Xcode 26 (extracted with unxip-rs) and darwin tools from 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. It was built on a lot of other libraries, so check out its README for more info.

Credits

• idevice is used to communicate with iOS devices.
• xtool has been used as a reference for the implementation of the darwin SDK generation.
• Sideloader has been heavily used as a reference for the implementation of the Apple Developer APIs and sideloading process.
• GNU cpio 2.14 is included under GPLv3 (see licenses/GPL-3.0.txt), with its copyright holders. See Source code. It is used to help with XIP extraction.

AI Usage

• Helped port small sections of code from Sideloader because I'm not familiar with dlang syntax
