The speculation around Apple's VR headset for the iPhone has been circling for some time now. We may even get it not too long from now to compete the Google Daydream. But Apple has it's eye's set on AR, and it's clear. Partly because you don't need a headset, and the technology to perform good quality AR with your phone is here and mature.
The introduction of the dual camera lens on the iPhone X added depth mapping which allows the phone to more accurately place things on a surface in the field of view. Even portrait mode is similar to an AR type of interaction. But AR is nothing new, here's an example you probably didn't realize but has been around for quite some time.
Your car's backup camera may have an AR view of the direction your car will move. This has quickly become a standard feature for most cars and is a form of AR.

Another example in cars making it's way slowly into the market is the HUD. A useful feature for drivers to see their dashboard without looking away from the road.

Other examples include snapchat filters which took off a few years ago and Apple is following up in iOS 12 with Animoji in facetime. Which should be a fun addition to video chatting with friends and family.

I think we'll see a lot more exciting developments in the AR space over the next few years. The technology to get VR experiences with high fidelity is at least a few years away. Including pixel densities, small FOV lenses, and other kinds of equipment like omni-directional treadmills to enable full immersion.
