Xcode & iOS App Signer (macOS) - raziel6868/uYouPlus GitHub Wiki

I would not recommend you use this method unless other methods don't work or you somehow have a developer certificate. Install Xcode which takes 30 - 40GB+ of your space to sideload an IPA is simply not worth it.

iOS App Signer is open source and you can see its source code here. The usage of iOS App Signer is available on its homepage
