At WWDC 2018, Apple continued to push the envelope with ARKit by releasing ARKit 2. Late in 2017, Apple released ARKit 1, which allowed users to place 3D objects in the real world. This technology was showcased by companies like Ikea who allowed users to try out furniture in their homes. A few months later, Apple released ARKit 1.5. This release gave users the ability to detect not only horizontal planes like the floor of their homes, but also their walls. In addition to vertical plane detection, Apple added Image Recognition, which allowed users to detect images and paintings just by pointing their phones at them. At WWDC 2018, Apple introduced enhancements to face tracking, as well as the following new features: saving and loading maps, environmental texturing, image tracking, and object detection.
