Which xCode do we use with the Teaching App Development with Swift Curriculum?

I am trying to get my students computers set up to teach using the Teaching App development with Swift curriculum. I am having a hard time figuring out which Xcode to download. I seem to be getting errors when I use 6.3 that the instructor on the video uses and on the newest 7.3.1

Xcode 6.3 was w/swift 1.2


Xcode 7.3.1 is w/swift 2.2


If that TAD uses old tools and you want to get along w/it, then you're obligated to xcode 6.3, I think.


Not sure I'd bother with it, tho...if you're going to put something in front of students, it would only frustrate them outside of your lab. I'd find aonther TAD.
