iOS / Swift, the SDK, and ZPL



We bought a ZQ520 to investigate integrating it into an ad-hoc iPad app we're building to print a variety of custom receipts.   If it works to our satisfaction we'll be rolling out dozens of the printers.


  1. I'm wondering if anyone has an example of using the SDK within and iOS app with Swift while implementing a Bridging Header?  I've used plenty of Bridging Headers in the past, but the documentation surrounding using the SDK in a modern Swift environment is non-existent.  In the SDK there's a mountain of header files in the /include directory, but I'm not sure which headers to import in the Bridge file. 
  2. EDIT: I'd figured out the ZPL side of things if someone could help with the bridging question above.


Any hints or pointers would be greatly appreciated.
