title: It gives errors when using Swift Static library with Objective-C project
body: <p>I need to make swift static library for my requirement. I made swift static library which uses swift and Obj-c code. I have included Obj-c files via bridge file. I am able to compile swift static library without any error and get libMySwift.a file. I use Xcode9.3 with Swift4 to compile library.</p>
  
  <p>I include libMySwift.a in obj-c project and also included obj-c compatible header to access my lib in the project. When I try to compile the project it give below warning and more than 200 errors. </p>
