i have found a great course for those interested in learning iOS 9 programming. The instructor has taught before and has great reviews. I have purchased the course and am looking forward to going through it.
MacRumors has an 87% percent discount until end of day August 4th. You can go visit the site to get the discount code.
Regular course is $199. I would keep checking for deals if you miss it.
