title: NS_Deprecated equivalent for 3rd party frameworks
body: <p>NSDeprecated which tunnels through CF_Deprecated into the clang attribute availability only handles deprecation for MACOSX and IOS.</p>
  
  <p>Are there any calls or series of macros that replicate this tool for third parties.</p>
  
  <p>I am working on V2 of an SDK and there are certain calls we want to deprecate as well as EOL. </p>
  
  <p><em>(Please note, this SDK is still in Objective-C; so Swift only solutions don't solve my issue)</em></p>
  
  <p>The deprecation warnings and errors would be fantastic at compilation and code generation time; however, I fear this is something I'd need to spin on my own.</p>
  
  <p>Any pointers or reference on this before I have to decide if I need to kill the time on this side project?</p>
