title: Adding framework projects in Xcode
body: <p>I am pretty new in iOS development, and I found a library I'd like to use in my app:</p>
  
  <p><a href="https://github.com/ustwo/US2FormValidator" rel="nofollow">https://github.com/ustwo/US2FormValidator</a></p>
  
  <p>I followed the steps the authors described in their documentation to import their project into mine, but Im not able to #import the imported project's .h files from my code. I also see that the library item in target's build phases remains in red. Maybe I am not importing the project properly, I copied the whole project folder into mine's folder, and then in the Xcode's project navigator of my project: right click > Add files to project > select the .xcodeproj file of the project I want to import, and that have been copied into my project folder. Is that the way to do this?</p>
