Support status

iOS 12 is the twelfth major release of the iOS mobile operating system developed by Apple Inc. Aesthetically similar to its predecessor, iOS 11, it focuses more on performance than on new features, quality improvements and security updates. Announced at the company's Worldwide Developers Conference on June 4, 2018, iOS 12 was released to the public on September 17, 2018.^[3] It was succeeded for the iPhone and iPod Touch by iOS 13 on September 19, 2019 and for the iPad by iPadOS 13 on September 24, 2019. Security updates for iOS 12 continued for three years following the release of iOS 13 for devices unable to run the newer operating system. Security updates then ceased for iOS 12, making 12.5.5 the last update for iOS 12.
