Swift and iOS8 Apps in 31 Days: Build 16 iPhone apps - $10 only
I just signed up for one of those Udemy courses: Swift and iOS8 Apps in 31 Days: Build 16 iPhone apps The 'list price' is $199, which I think, considering the contents of the course and the support available is a fair price.
However, being the cheapstake that I am, I searched for one of those 'coupons' on the web and found one there: http://udemycoupon.discountsglobal.com/coupon-tag/swift-and-ios8-apps-in-31-days-build-16-iphone-apps-coupon/ Now the course only cost $10 - not bad. It may last or it may not, so grab it while it lasts, and enjoy this course.
PS. The Udemy app on the iPad looks very promising too; it downloads the contents while online for offline viewing.
