title: classes vs frameworks in Objective-c with C++
body: <p>I would like to create some libraries in C++, these libraries will be able to model physical phenomena. I would like to build a cross-platform environment where these libraries are updated independent of the GUI, in my case a PC application and a iOS app would be the clients of such libraries.</p>
  
  <p>In terms of performance, easiness to plug C++ code, etc., what would be your recommendation? to generate a C++ classes and call them from other classes with the .mm extension or to generate a framework in c++.</p>
  
  <p>Would you recommend something different to C++ for cross-platform compatibility?</p>
  
  <p>NB: I am not an experienced programmer but trying to get into a decent level.</p>
  
  <p>Thanks,
  Alejandro</p>
