Forgive my ignorance if this is a simple question. I'm working on my first app. I updated XCode and Xamarin to the latest for support of iOS7. I'm using TestFlightApp to distribute the app to a beta test group. After creating my iOS7 version, I can't install the app on any device with iOS6. While that makes sense, I need to support both operating systems for a period of time.
What do I have to do the allow the app to run in both versions? Thanks in advance from a newbie!
