Apple iOS 12 - definition
iOS 12.0
iOS 12 was introduced during Apple's Worldwide Developers Conference on June 4, 2018 and was released to the public on Monday 17 September 2018.
Following the criticism leveled at iOS 11, iOS 12 for Apple was a consolidation release. Refining existing features and under the hood improvements as opposed to feature overload.
And boy, did it deliver on its promises. In our testing on older iDevices, iOS 12 made them feel much more sprightly when compared to iOS 11.
