Whilst I was developing avTag I started using HockeyApp to distribute builds to beta testers. As part of that process I decided to follow their advice and configure my project so that I could have debug, beta and App Store builds all installed on devices concurrently. You then have access to the three states of your application quickly and easily. However I found some of the configuration notes slightly confusing and although Andreas Linde gave me some very handy notes I've decided to write things up in a more agnostic way. I wholeheartedly recommend HockeyApp but realise that some of you are either tied in to things like TestFlight or simply don't use a distribution service.
