Improved Face ID
One of our favorite updated features in iOS 12 was actually completely glossed over at WWDC. Face ID is getting some major improvements in the next version of iOS.
You can now add two different Face ID profiles to unlock your phone and complete secure tasks. Hidden in the Face ID & Passcode settings, you’ll now find an option to add an alternate appearance.
It’s also easier to rescan your face in iOS 12 if Face ID did not recognize you on the first try. In iOS 12 you simply need to swipe up from the unlock screen Face ID failed on the first attempt. It’s a relatively minor enhancement, but one that makes using Face ID much more convenient.
In particular, iOS 12 will be focused on doubling down on performance. Apple plans on delivering an operating system that’s faster and more responsive across all iOS devices. The focus has mainly been on optimizing the system when it’s under load, with load speeds up to two times faster for sheet display and app launches.
CPU performance will also be ramped up to its highest state for performance and will be ramped down just as quickly in order to preserve battery life.
One more upgrade that Apple didn’t mention at its keynote is the improved animations. When transitioning from one app to the other, the transition animations are smoother and faster than they are on iOS 11.
