title: adding 'use_frameworks!' in podfile is breaking app
body: <p>My iOS app contains both objective-C and Swift code. Now i have added <strong>use_frameworks!</strong>  at the top of pod file to use some swift library. Unfortunately it started giving compilation errors.</p>
  
  <p>My pod version : 0.39.0</p>
  
  <p>It started complaining about imports in bridge.h file </p>
  
  <p>Pod file contains objective-C libraries. Now i want to add swift libraries.</p>
  
  <p>How can i fix this issue. Let me know if needs more details</p>
