Of course everyone knows about WWDC, the developer conference that Apple holds every year in June, but there are quite a few independent conferences all across the world. The range of topics between the different conferences is wide so how much is relevant at any particular event will depend on the person. Though the original purpose of this post was solely to put together a collection of links to the videos that have been put up for the talks presented, there is an added side benefit. If you are thinking of attending a conference then watching some of the videos can give you a better idea of which ones might be the right fit for you and help make sure you are using your time and money efficiently!
