IOS

iOS, formally known as iPhone OS, is the mobile operating system for Apple Corporation's iPhone. The software was introduced on January 9, 2007 and publicly available on June 29, 2007, which was originally marketed as OS X, Apple's desktop operating system. For the first three years of iOS versions, the operating system was referred to as iPhone OS before being renamed in 2010 to iOS, due to the expansion of the software being made available to the iPad.

Currently, the latest public release of the operating system is iOS 13.6, which launched in July of 2020. In testing, iOS 14.0 has been made available as a beta to registered developers and public beta testers, and will be made available to the public in October.

History
On January 9, 2007, Apple hosted their annual Macworld keynote, Apple introduced iPhone running on iPhone OS, the former name of iOS. The operating system was very simple with a phone, web browsing, an iPod music player, alongside other default apps that users could use. The whole OS supported Apple's new invention of multi-touch displays and a rubber banding effect to make the user understand that they have reached the end.

At Macworld, the iPhone was announced to be running a desktop-class OS, Mac OS X. Before release, Apple made the iPhone run on its own OS, iPhone OS, which would later develop into iOS due to the support of Apple's new product line, iPad.

Since iOS' release, there have been major updates to the operating system annually that result in the iOS version number to increase incrementally. Since 2007, there have been 13 major releases of iOS, with a new major release currently in testing by registered developers and public beta testers set to be released later this year.
