There are tools and scripts available that can automate the process of injecting a dylib into an IPA, handling the necessary path adjustments.

Before diving into injection, you must understand why injection is non-trivial on iOS.

| Problem | Solution | |---------|----------| | App crashes on launch | The dylib may be incompatible or missing dependencies. Check device logs. | | LC_LOAD_DYLIB rejected | iOS 13+ blocks some dylib paths. Use @executable_path or @rpath . | | Codesign error: resource fork | Remove extended attributes: xattr -cr MyApp.app | | App detects injection | Use stealthier injection methods or hook detection bypasses. |
