Is there an order I can look at in watching the video tutorials? Thanks
@hemolyticus This all depends on what level of an iOS developer you are, and where your interests/weaknesses lie. If you’re new to Swift, I would advise you to start off with the beginner Swift video course, and gradually work your way up to the advanced Swift course. With respect to iOS development, I would start off with the courses under the “Getting Started” heading, and work your way through each course. Once you feel more confident, you can then go to the intermediate, and advanced levels of some of the topics that you’ve already covered.
If you’re unsure about choosing one course over the other, select one, and see what the introduction states about the course. If there are prerequisites, the presenter will mention what concepts you should be familiar with before taking a particular course 
I hope that helps!
