Hi Brian, thanks so much once again for putting together such a comprehensive course. I may have discovered a bug here that you may have overlooked, and I apologize if this is my oversight:
It appears that I'm allowed to download an episode of a particular podcast multiple times (i.e. we are not checking for duplicates). If I continuously swipe an episode from the EpisodesController UITableView, and click download each time, and then go to the DownloadsController, I see the multiple downloads that I've made. I'm bringing this up because you did not list this as one of the challenges at the end of this episode. Could you provide a fix for this?
Thanks once again for your hard work!
