UPDATE: Looks like it's a third party port made by an enthusiast, at least according to the post Google+. So keep moving, nothing to see here. Although, the question remains, would you play Ingress if an official version does come to iOS?
Google’s popular Android game Ingress looks like it may be making its way to iOS at some point in the future. A Github repository has been found that contains resources for an iPhone version of the game, including links to gameplay videos.
