Inject Dylib Into Ipa ~repack~

: After modification, repackage the Payload folder back into a ZIP file with a .ipa extension. To install it on a non-jailbroken device, you must re-sign the entire application bundle (including the new dylib) with a valid iOS development certificate. Tools like iOS App Signer can help automate this signing process.

The most reliable way to do this without jailbreaking a device is by injecting a directly into an iOS App Store Package (IPA) file.

Your .dylib may rely on other dynamic libraries (e.g., libsubstrate.dylib ). You must copy these dependencies into the .app/Frameworks folder and verify they are signed. Use otool -L yourLib.dylib to check for missing dependencies. Failure to include them will cause the injected library to fail to load, leading to an app crash.

Using specialized tools is the most common way to automate the injection and re-signing process. Inject Dylib Into Ipa

Before signing the whole app, sign the injected dylib using your development certificate:

The Mach-O format used by iOS and macOS for shared libraries. This contains the compiled C, C++, or Objective-C/Swift code you want to run inside the app.
