Thanks for letting me know Peroni :) I actually come across Amsys ones in my Googling, can be difficult to know if they're legit or not though.
Charley from Amsys here... just thought I'd let you know we're an Apple Authorised Training Company and have been teaching iOS development courses for the last 5 years. We have a range of Swift dev courses. If you're already an iOS developer then we'd recommend this course.

Also.. as we're approaching the 1st anniversary of Swift... you can book on any Swift course running in June and save 20%.
Thanks, Charley
