SiriKit was created for developers in iOS 10. However, there were, and still are, a limited number of intent domains with which you can integrate an app. An intent domain is simply a category of app that can take advantage of Siri. With the release of iOS 11, a few new domains are being made available. This tutorial will walk through implementing SiriKit with the “Lists and Notes” domain, although, the core concepts can be applied to any domain.
