It is the second most widely installed mobile operating system in the world, after Android.

iOS was unveiled with the first-generation iPhone on January 9, 2007, and released on June 29, 2007. Initially, iOS was named "iPhone OS," but it was renamed to "iOS" in June 2010 with the introduction of the iPhone 4.
Features[edit | edit source]

User Interface[edit | edit source]
The iOS user interface is based on direct manipulation, using multi-touch gestures. Interface control elements consist of sliders, switches, and buttons. Interaction with the OS includes gestures such as swipe, tap, pinch, and reverse pinch.
Security[edit | edit source]
