title: project works fine on Xcode 9.0.1 but shows errors on Xcode 9.2
body: <p>Please help me I have no idea why it shows error in my Mac with Xcode 9.2 but the same project works fine with a Mac which has Xcode 9.0.1.</p>
  
  <p>The errors it throws are </p>
  
  <ul>
  <li>Module compiled with Swift 4.0 cannot be imported in Swift 3.2.3</li>
  <li>Header '****-Swift.h' not found</li>
  <li>Could not build Objective-C module '****Lib'</li>
  <li>Command /usr/bin/ditto failed with exit code 1</li>
  <li>clang: error: no such file or directory</li>
  </ul>
  
  <p>are the errors due to some missing files? please help me figure it out.</p>
