Some people dig for gold. Others dig for ancient artifacts. Still other dig through every bit of code, even those normally indecipherable to humans, to glean a different kind of treasure: the digital kind. That was what Twitter user Chase Fromm was doing when he came across a reference to "LiFiCapability" among the other hardware and software capabilities that iOS 9.1 advertises. This hints that Apple might be planning to introduce support for that Li-Fi wireless communication technology sometime in the near future of iOS and iPhones.
