This isn't the first time this year that Munster has discussed Apple's plans for AR. Back in March, Munster told clients that Apple had put together a small team to explore the use of augmented reality. At that time, Munster was quoted as saying that AR could be "as profound a technology platform as the smartphone today."
There is speculation that Apple is going to use augmented reality for Apple Maps. Users would be able to open the Maps application and point their camera at a business or a point of interest that they are interested in. An overlay would appear on the screen with information about that particular location.
So far, there has been no indication from Apple that AR will be a part of iOS 9.
