iOS

The version history of the mobile operating system iOS, developed by Apple Inc., began with the release of iPhone OS for the original iPhone on June 29, 2007. Since its initial release, it has been used as the operating system for iPhone, iPad, iPod Touch, and HomePod, seeing continuous development since then, resulting in new major releases of the software typically being announced at the annual Apple Worldwide Developers Conference and later released in September, coinciding with the release of new iPhone models.
