Consuming a swift cocoa touch framework in Obj-c app

I am trying to write a Cocoa touch framework. But not sure which langue is better to use, swift or objective-C. The framework will be consumed by both obj-c and swift apps. I am leaning toward writing the framework with swift. How easy would it be for an obj-c app to use a swift Framework? What things should I consider when I write the framework in swift to make it work on obj-c apps or even older iOS versions.Thank you

Hi @ftd,
You could use either, the one that you are more comfortable with would be the logical choice. However if you are comfortable with Objective-C I would recommend using Obj-C for a shared framework as it is too easy to start using Swift features in code and they don’t translate back to Objective-C especially enums, that’s my two bits on this,
