iOS is a mobile operating system developed by Apple Inc. It was first released as iPhone OS in June 2007.[1] iPhone OS was renamed iOS following the release of the iPad, starting with iOS 4.[2] With iOS 13, Apple began offering a separate operating system, iPadOS, for the iPad. iOS is also the foundation of the newer audioOS and tvOS, and shares some of its code with macOS. New iOS versions are released every year alongside new iPhone models. From its launch in 2007 until 2010, this occurred in June or July, since then, new major versions are released in September or October.
Apple announced iPhone OS 1 at the iPhone keynote on January 9, 2007, and it was released to the public alongside the original iPhone on June 29, 2007.[3] No official name was given when the iPhone was released; Apple marketing literature simply stated the iPhone ran a mobile version of "OS X".[4] During the development phase of iPhone OS 1, there were at least 17-18 different concepts developed. Many on the team were still hung up on the idea that everyone would want to type on a hardware keyboard, not a glass screen. The idea of introducing a complete touch screen was very novel to everyone.[5] Many user interfaces were prototyped, including the multi-touch click-wheel. Although many thought it was a waste of time, Apple CEO Steve Jobs insisted on prototyping all concepts before the Mac OS-X-based version of the operating system was selected. The release of iPhone OS 1.1 brought support for the iPod Touch (1st generation). iPhone OS 1.1.4 is the final version of iPhone OS 1 for the iPhone, and iPhone OS 1.1.5 is the final version of iPhone OS 1 for the iPod Touch (1st generation). It was succeeded by iPhone OS 2 on July 11, 2008. It became unsupported on May 18, 2010.

Apple announced iOS 14 and iPadOS 14 on June 22, 2020, at its annual WWDC 2020 event, with a developer beta released on the same day and a public beta released on July 9, 2020.[103] iOS 14 and iPadOS 14 were released on September 16, 2020, alongside the iPad (8th Generation) and iPad Air (4th Generation). All devices that supported iOS 13 also support iOS 14. This makes the iPad Air 2 the first device to support seven versions of iOS and iPadOS, from iOS 8 to iPadOS 14. Some new features introduced in iOS 14 and iPadOS 14 include redesigned widgets that can now be placed directly on the homescreen (only for iOS), along with the App Library, which automatically categorizes apps into one page, Picture in Picture in iPhone and iPod Touch, and the CarKey technology to unlock and start a car with NFC. iOS and iPadOS 14 also allow the user to have incoming calls shown in banners rather than taking up the whole screen (the latter view is still available as an optional function).[104] It was succeeded by iOS 15 and iPadOS 15 on September 20, 2021.
The release of iPadOS 14.0 brought support for the 8th generation iPad and the 4th generation iPad Air and the release of iOS 14.1 brought support for the iPhone 12, the iPhone 12 Mini and the iPhone 12 Pro and Pro Max. iOS 14 and iPadOS 14 have limited support on devices with A8, A8X, A9, A9X and A10 Fusion chips, whereas devices with A10X Fusion and A11 Bionic chip have almost full support, and devices with A12 Bionic chip and later have full support.[citation needed]
