== Overview ==
'''iOS''' is a mobile operating system developed by [[Apple Inc.]] exclusively for its hardware, including the [[iPhone]], [[iPad]], and [[iPod Touch]]. Originally unveiled in 2007 as '''iPhone OS''', it was renamed iOS in 2010 after Apple licensed the name from [[Cisco Systems]]. iOS is the second-most widely installed mobile operating system worldwide, after [[Android (operating system)|Android]].

== History ==
The first version, iPhone OS 1, shipped with the original [[iPhone (1st generation)|iPhone]] in June 2007. It lacked an [[App Store]] and third‑party native apps, relying instead on [[web application]]s. In July 2008, iPhone OS 2 introduced the [[App Store (iOS)|App Store]], allowing developers to distribute native applications. The platform was renamed iOS 4 in 2010, alongside the introduction of [[multitasking]] and folders.

Subsequent versions added major features: iOS 5 (2011) brought [[Siri]] and [[iCloud]]; iOS 7 (2013) introduced a completely redesigned flat interface; iOS 10 (2016) opened [[Siri]] to third‑party apps; and iOS 14 (2020) added widgets to the home screen and the [[App Library]]. Each annual release has refined privacy controls, performance, and integration with Apple’s ecosystem.

== Features ==
iOS is known for its closed ecosystem and tight hardware–software integration. The operating system uses a layered architecture based on [[Darwin (operating system)|Darwin]] ([[XNU]] kernel). Core features include:

* '''User interface''': A touch‑based interface using direct manipulation gestures (tap, swipe, pinch). The home screen consists of a grid of app icons, a dock, and a notification center.
* '''App Store''': Apple’s centralized digital distribution platform for third‑party applications, with strict review guidelines.
* '''Siri''': A voice‑controlled intelligent assistant that can perform tasks, answer questions, and control smart home devices via [[HomeKit]].
* '''Security and privacy''': iOS enforces sandboxing for apps, requires user permissions for location and data access, and offers [[Face ID]] and [[Touch ID]] biometric authentication.
* '''Continuity''': Seamless handoff between iOS and [[macOS]], including features like [[AirDrop]], [[Handoff]], and [[Universal Clipboard]].

== Versions ==
Major releases are typically announced at [[Apple Worldwide Developers Conference|WWDC]] in June and released in September. As of 2025, the latest stable version is [[iOS 19]]. Each version is named after a California landmark (e.g., iOS 13 "Catalina", iOS 15 "Monterey").
