iOS

iOS is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that presently powers many of the company's mobile devices, including the iPhone, iPad, and iPod Touch. It is the second most popular mobile operating system globally after Android.

Apple first unveiled iOS in 2007, the same year it released its first iPhone. Since then, iOS has been regularly updated to add new features, fix bugs, and improve performance. It is currently in its 16th iteration with iOS 16, released in September 2022.

iOS is designed around the idea of 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, all of which have specific definitions within the context of the iOS operating system and its multi-touch interface.

iOS offers a range of features, including AirDrop, an ad-hoc service for sharing files between devices, Handoff, which enables users to switch between multiple Apple devices and apps, iCloud, a cloud storage and cloud computing service, and HealthKit, an application that allows users to track and manage their medical data. iOS also includes a wide range of built-in apps, such as Messages, Mail, Maps, Calendar, and Notes.

Apple releases new versions of iOS periodically, usually once a year. Each version of iOS generally consists of several minor updates and bug fixes, with major updates being released on an irregular schedule. iOS development is the process of creating applications for Apple's mobile operating system, iOS. It is one of the most popular mobile app development platforms, and is used by millions of people around the world.
