  • See http://stackoverflow.com/questions/26024100/dyld-library-not-loaded-rpath-libswiftcore-dylib try reissuing your certificates. Worked for me. – cudds Oct 03 '14 at 17:01
  • tell a lie - the same thing. Got rejected. I cannot reproduce the crash – cudds Oct 04 '14 at 05:47
  • Uh，but my development environment will crash as long as the real machine debugging, Is not related to the environment? I installed two versions of xcode, one is 5.1.1, one is 6.0.1 – yong gao Oct 08 '14 at 07:43

  • I estimate the Apple fixes this bug, with xcode6.1, no problem, thank you! – yong gao Nov 15 '14 at 06:54

This issues seems to be caused by the certificate. Apple filled the Organization Unit in the certificate. So you need to request a new certificate en install that one. The field will be filled and your app will work properly.

  • Very important: revoking your signature is pretty much instant; it means the old certificate is immediately unusable! This lesson we learned the hard way when about 600 ipads were rendered useless since the app wouldn't reinstall/boot anymore – Kevin R Dec 11 '14 at 15:19
  • Worked for me only when deleting and creating in XCode, developer.apple.com's "Certificates, Identifiers & Profiles" tool apparently created new bad certs. – Graham P Heath Dec 15 '14 at 18:59

Just go to your certificates in Keychain , Right Click -> Get Info -> Trust - > find a field with name "When using this certificate"-> Select "use system default" option.
