Inject Dylib Into Ipa -

cmd LC_LOAD_DYLIB path @executable_path/YourTweak.dylib Modern apps detect dylib injection via:

| Detection method | Bypass strategy | |----------------|----------------| | dyld environment variables ( DYLD_INSERT_LIBRARIES ) | Use hardcoded LC_LOAD_DYLIB instead (no env var) | | Checking _dyld_get_image_name() | Patch detection function or hook it | | Code signature validation | Use codesign --force --deep --sign with valid cert | | Jailbreak detection (checking /Library/MobileSubstrate) | Use rootless JB or relocate dylib to /var/jb/... | Inject Dylib Into Ipa
