I'm trying to run an app that has a .dylib listed in the configuration of the application as "Embed & Sign" I can confirm it is correctly signed by inspecting the package using codesign -dv --verbose=4 lib_paths.dylib and it gives me the following: Executable=/Users/blablabla/Debug-iphoneos/TestApp.app/Frameworks/lib_paths.dylib Identifier=lib_paths Format=Mach-O thin (arm64) CodeDirectory v=20400 size=784 flags=0x0(none) hashes=16+5 location=embedded VersionPlatform=2 VersionMin=917504 VersionSDK=1049600 Hash type=sha256 size=32 CandidateCDHash sha256=7eaecbb8e00114767c9de0ac9054213620052212 CandidateCDHashFull sha256=7eaecbb8e00114767c9de0ac90542136200522121105dd217b38bd27e1fda4de Hash choices=sha256 CMSDigest=7eaecbb8e00114767c9de0ac90542136200522121105dd217b38bd27e1fda4de CMSDigestType=2 Executable Segment base=0 Executable Segment limit=32768 Executable Segment flags=0x0 Page size=4096 Launch Constraints: None CDHash=7eaecbb8e00114767c9de0ac9054213620052212 Signature size=4795 Authority=Apple Development: myemail@address.com (XXXXXXXXX) Authority=Apple Worldwide Developer Relations Certification Authority Authority=Apple Root CA Signed Time=13 Dec 2023 at 21:39:28 Info.plist=not bound TeamIdentifier=XXXXXXXXXXX Sealed Resources=none Internal requirements count=1 size=180 But when trying to run the application, I am getting the following error: Referenced from: '/private/var/containers/Bundle/Application/3142F1F2-547B-41B5-8EF4-239F4EAD2A4F/TestApp.app/FSVTestApp' Reason: tried: '/usr/lib/system/introspection/lib_paths.dylib' (no such file), '/usr/lib/swift/lib_paths.dylib' (no such file), '/private/var/containers/Bundle/Application/3142F1F2-547B-41B5-8EF4-239F4EAD2A4F/TestApp.app/Frameworks/lib_paths.dylib' (code signature invalid (errno=1) sliceOffset=0x00000000, codeBlobOffset=0x0000C5E0, codeBlobSize=0x00004B50 for '/private/var/containers/Bundle/Application/3142F1F2-547B-41B5-8EF4-239F4EAD2A4F/TestApp.app/Frameworks/lib_paths.dylib'), Note that I enabled the "Automatically manage signing" option, and using a Personal Team. This seems to work fine for the application itself (otherwise it wouldnt even try to load the dylib). What is going on ?
