I am trying to use class-dump in iPhone 14.3. However, there is an error. Can you advise?

ANT-iPhone:/var/containers/Bundle/Application/61669A90-8CF9-4991-943F-5E9F097A3A5B/Hello_World.app root# otool -Vh Hello_World

Hello_World:
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags


MH_MAGIC_64   ARM64        ALL  0x00     EXECUTE    24       2840   NOUNDEFS DYLDLINK TWOLEVEL PIE


ANT-iPhone:/var/containers/Bundle/Application/61669A90-8CF9-4991-943F-5E9F097A3A5B/Hello_World.app root# class-dump Hello_World

class-dump: Input file (Hello_World) is neither a Mach-O file nor a fat archive.

  • We don't support 64-bit Mach-O files indicates that the class-dump tool is outdated as all iOS software is now 64 bit. I would download the whole .app directory and open the binary in Ghidra. – Robert Mar 06 '23 at 15:37
  • Can class-dump software swift programming language by the way? – A O Mar 07 '23 at 01:57
  • The first 64bit iPhone was introduced 2013, Swift was introduced 2014 (and became binary stable AFAIR ~2019). If class-dump does not support 64bit how likely it is it supports Swift which was introduced later? – Robert Mar 07 '23 at 08:41
