Hi
Im in the middle of learning Swift 2.0 but Swift 3.0 has just been released. Would you advise for me to start Swift 3.0 or finished the whole module of Swift 2.0?
Any advise would be much appreciated.

While some changes that exist in an update to the language may be 'breaking', it is a good idea to continue learning the base foundation of how the language works. Also, it is good to know the differences in language versions as you may come across it in forums, online code, code in a workplace or 'in the wilds'.
Swift 3 has some pretty notable changes, but there isn't really anything you will learn from the Swift 2 courses that won't be useful when learning Swift 3. Each iteration of a language generally builds on top of its predecessors.
FYI: There is no reason you cannot watch the Swift 3 courses in between watching a Swift 2 course, as you will notice, it will most likely be the same course with some minor syntax changes here and there. If you are feeling adventurous and learn a little about Swift 3 on the side, try to implement a Swift 2 challenge and convert it to also work in Swift 3!

22,311 PointsI would recommend learning the Swift 2 app development track. Treehouse allows you to switch tracks at any given time, therefore if a full Track becomes available for Swift 3, you can switch. Learning Swift 2 would be beneficial as well if you plan to look at online forums and potentially seeing code someone else has written that may be in Swift 2. Most differences should be obvious and Xcode will help in notifying it as an error, but being able to easily read Swift 2 code without specifically being told it is Swift 2 and not Swift 3 can be useful in staying away from headaches later down the line.
