iOS Maps was obviously not one of Apple’s better efforts but that doesn’t mean the executive who oversaw its implementation has nothing to contribute to the tech world. Bloomberg reports that Facebook has hired Richard Williamson, the former Apple executive who headed the development of the ill-fated iOS Maps, to work as part of its mobile software team. Although iOS Maps was certainly a disaster for Apple, it doesn’t tell the full story of Williamson’s career — as Bloomberg notes, he worked at Apple for more than 10 years and was “one of the engineers assigned by Apple co-founder Steve Jobs to build software for the iPhone.” So unless Facebook hired Williamson to oversee the creation of its own mapping application, it seems safe to say the company has found itself an experienced executive who can help improve its mobile offerings.
