Xcode在编译时突然发现错误

Question

我不明白，为什么Xcode开始失败。它工作正常，但现在不行。 为什么？有什么想法吗？

dyld: Library not loaded: @rpath/libswiftCore.dylib
  Referenced from: /var/containers/Bundle/Application/5F0F3220-FB4F-4AF1-BC9E-6EF464E24448/signum.app/signum
  Reason: no suitable image found.  Did find:
/private/var/containers/Bundle/Application/5F0F3220-FB4F-4AF1-BC9E-6EF464E24448/signum.app/Frameworks/libswiftCore.dylib: code signature invalid for '/private/var/containers/Bundle/Application/5F0F3220-FB4F-4AF1-BC9E-6EF464E24448/signum.app/Frameworks/libswiftCore.dylib'
