| iOS version history | |
iOS (formerly iPhone OS)[6] is a mobile operating system developed by Apple exclusively for its mobile devices. It was unveiled in January 2007 for the first-generation iPhone,[7] which launched in June 2007. Major versions of iOS are released annually; the current stable version, iOS 18, was released to the public on September 16, 2024.[8]
It is the operating system that powers many of the company's mobile devices, including the iPhone, and is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS.[9] iOS formerly also powered iPads until iPadOS was introduced in 2019, and the iPod Touch line of devices until its discontinuation.[10] iOS is the world's second most widely installed mobile operating system, after Android. As of December 2023, Apple's App Store contains more than 3.8 million iOS mobile apps.[11]
iOS is based on macOS. Like macOS, it includes components of the Mach microkernel and FreeBSD.[12][13] It is a Unix-like operating system. Although some parts of iOS are open source under the Apple Public Source License[14] and other licenses,[15] iOS is proprietary software.[16][17]
