One of the unique features provided by the amazing Esign IPA installer is the possibility to inject tweaks (dylib, framework, deb) into sideloaded apps. You may use this IPA signing tool to extract the IPA archive, copy the injection frameworks, repackage it, and then sign the updated app to sideload it. To inject tweaks to an iOS application using Esign, follow these instructions. All features are available on-device.


  • To inject dylib, framework, or deb into IPA files you can use an on-device application like Esign. The process of injecting tweaks is easy to follow.
  • Esign offers an option not only to inject tweaks into IPA files but also to remove frameworks from applications before installing them on your iDevice.
  • The best practice to inject tweaks into iOS apps is to utilize dylib instead of deb packages. You can extract dylib from deb files by unpacking them with Zip.


  • Installed the latest version of Esign.
  • iDevice running iOS 14 – iOS 17.
