According to the report, Apple has features LiFiCapability since iOS 9.1, which could suggest that they currently have some iPhones in testing using LiFi.
LiFi works in a similar way to an infrared remote, it transmits data by rapidly modulating a light source, the light is then received by a sensor and then translated into an electronic signal.
The feature uses visible light, this means that the lights in your house could act as an access point for the feature, it is considerably faster than WiFi with speed of up to 224 gigabits a second.
It could be a few years before we see this technology in future Apple devices as it is apparently still in the experimental stage.
