Is there a Prefix Header (or something with this functionality) in Swift?

Question

Is there a way to get the functionality of a prefix header in Swift? I don´t want to import external libs in every file where they are used.

Answer 1

1. Create a Objective-C Bridging Header file:

   [New File→iOS→Source→Header File]: Bridging-Header.h

2. Go to this new header and import your external libs:

   @import Module1Name;
   @import Module2Name;
   ...
   

3. Go to Build Settings, set the path of Objective-C Bridging Header:

   [Target→Build Settings→Swift Compiler - Code Generation→Objective-C Bridging Header]: $(SRCROOT)/.../Bridging-Header.h

Then you can use external libs in every file without import code.
