How to support iOS7 using Amazon's AWS in Swift (dynamic framework issue)?

I'm building an app in Swift which uses AWS S3 (amazon web services) and I'd like to support iOS7. When I add Amazon's framework to the project using cocoa pods the app crashes on iOS7 devices. I know this is due to dynamic frameworks replacing static libraries but I'm not sure what can I do to support iOS7?

How to support iOS7 while developing in Swift and using 3rd party SDK?

Thank you

EDIT: I've read: iOS Static vs Dynamic frameworks clarifications but there was not enough help.
