title: Import own frameworks in Swift playground auxiliary code (under Sources)
body: <p>In a Swift playground (itself) I can use a framework which I compiled previously (and for which there is a target in Xcode workspace).</p>
  
  <p>However, I am NOT able to import that framework in a Swift file which I added to the playground as auxiliary code (under Sources).</p>
  
  <p>Does anyone know whether it's possible to configure framework search paths for a playground in the way so that a non-system framework can also be imported in auxiliary code of the framework?</p>
