SAN JOSE—iOS 12 is official, and, as predicted, it puts a heavy emphasis on improving performance and stability. At the same time, the latest iteration of Apple’s mobile OS is poised to bring a handful of noteworthy new features to iPhones and iPads as well.

The software update was announced during a keynote presentation at Apple’s annual Worldwide Developers Conference (WWDC). A developer preview is available today, with a public beta scheduled for later in the month. A full release will then arrive in the fall.

Apple says the update will be available on all the same devices as the current iOS 11 release, which includes the iPhone 5s and later, every iPad released since the original iPad Air and iPad mini 2, and the 6th-generation iPod Touch.
