Apple’s new software update, iOS 12, is available as a free download right now for anyone using the iPhone 5S and newer, iPod touch 6th generation or iPad models. 

The version is largely focused on performance improvements over features, with the company placing an emphasis on applications now launching faster than ever before. But it’s not totally feature-free, with Apple dipping its toes into augmented reality (AR) and voice support.
