objective c - Errors when trying to build static library for iOS -

I have an empty static library for iOS (which is empty - which means - I just define an interface without any methods was) when I tried it to make I get a bunch of errors:

  SecIdentityRef  and  SecTrustRef  defined  Security In Framework , make sure you are importing the appropriate header file:  
  #import & lt; Security / security. H & gt;   
 And add  security.framework  to your project.
