title: Is there a way to aggregate import statements in swift
body: <p>During my Objective-C days I used to include all the import statements such as UIKit, MKMapKit, and others in the *-prefix.pch file.</p>
  
  <p>However, what's left in Swift is just the info.plist file. So, I will have to repetitively include all the import statements in every swift files included in my project. Therefore, here I wonder if it's possible to so similar practice as how I did with the .pch file in Objective-C?</p>
