WWDC 2018 Video Transcripts Now Available
I always find the transcripts of the WWDC videos super useful, especially when it comes to researching particular topics across different WWDC events. Historically, I’ve used ASCIIwwdc for this but in recent years Apple have also started to publish their own transcripts. This year appears to be no exception with Apple this week announcing availability of the transcripts for WWDC 2018. Useful reference to keep in mind.

Welcome to another week of Swift Developments! Before we dive into the links this week I just wanted to mention that there isn’t going to be an issue of Swift Developments next week as circumstances have organised themselves in such a way that I’m going to be without any sort of internet connection for the week. Whilst unplugging for a week will no doubt be refreshing, it does mean that it’s going to be a little difficult to collect links for you. Apologies for the inconvenience but worry not, things should be back to normal the week after! Ok, with that out of the way, let’s get on with this weeks links. Enjoy.
