All iOS versions at a glance (from the first iPhone OS to today)

With the first iPhone in 2007, Apple also released the first mobile operating system for this and other devices. At that time, the portable offshoot of OS X on the Mac was still called “iPhone OS”. Later, the system based on Darwin, built on the XNU kernel and built in ARM architecture was simply called “iOS”.

It also functions as an operating system on the Apple iPod Touch. It was also used on the iPad until 2019, before it was replaced by the standalone iPadOS. Here you can find an overview of all iOS versions, with release dates and further information.

What is the latest iOS version?

The answer is: iOS 17. The new version iOS 18 will probably be presented at WWDC 2024 and released in fall 2024.

Because in addition to the first versions of the individual systems (always released with a new iPhone generation), there are several update stages, which usually range from the release to the next version. In addition, there are sometimes parallel updated versions such as iOS 12 for older devices and the following for newer devices.
