IOS version history
Updated: 12/11/2025, 9:38:06 AM Wikipedia source
iOS (formerly iPhone OS) is a mobile operating system developed by Apple Inc. and was first released in June 2007 alongside the first generation iPhone. iPhone OS was renamed iOS following the release of the iPad starting with iOS 4. With iOS 13, Apple began offering a separate operating system, iPadOS, for the iPad. iOS is also the foundation of watchOS and tvOS, and shares some of its code with macOS. New iOS versions are released yearly, alongside new iPhone models. From the launch of the iPhone in 2007 until the launch of iPhone 4 in 2010, this occurred in June or July; since then, new major versions are usually released in September, with the exception of iOS 5, which released in October 2011. Since the launch of the iPhone in June 2007, there have been nineteen major versions of iOS, with the current major version being iOS 26 which was released on September 15, 2025.
