: A popular desktop tool for Windows and macOS. It features a dedicated section where you can drag and drop multiple .framework files to be injected into your before it is sideloaded. iDevice ToolKit
iOS mandates that every executable and dynamic library in an application bundle must be code-signed. After injection, the original signature is broken. Therefore, the entire .app bundle must be re-signed using a valid provisioning profile and certificate. This is done using codesign (on macOS) or ldid (on Linux/jailbreak). For example:
cp /path/to/your/dylib.dylib /path/to/output/folder/Payload/app.app/Frameworks/
This post will walk you through what an IPA is, why you might want to inject code, and the step-by-step process to do it using command-line tools.
