Upgrade from 5th to 6th edition?

Last month I purchased the 5th edition and am now running into the syntax differences between it’s SWIFT 2 examples/instructions and SWIFT 3 in XCODE. Is there an upgrade path to the 6th edition?

I doubt it. Though if you get the ebook from the publisher with discounts and stuff it’s only like $28 (It lists for $39.99 but it is already marked down to $31.99 and then you get another 30% off for creating an account with them). I just picked it up. http://www.informit.com/store/ios-programming-the-big-nerd-ranch-guide-9780134682334

Much appreciated. The price is certainly reasonable but thought I’d ask before buying.

Just preordered 6th on Amazon for 30.34 bucks. I’m so excited, can’t wait to check it out.
