iOS 8 - While iOS 7 brought about the biggest visual change to the platform since its inception, iOS 8 is a refinement of the design iOS 7 established. iOS 8 came with the iPhone 6 and 6 Plus and the iPad Air 2. It contained new features like Apple Pay, a new Health app, HandOff, QuickType, Family Sharing, iCloud Drive, third-party keyboard support and (in mid-2015) Apple Music. Apple also introduced a new feature called Continuity that lets a user open apps on an iPhone or Mac. iOS 8 became the first iOS to have public beta testing available outside of developers before its initial release.
