Siri Shortcuts is now available to registered Testflight developers.
Developers who are registered to Testflight, Apple's application testing app, can request access to Siri Shortcuts through Testflight.
Siri Shortcuts was introduced at WWDC18, and will be available to everyone in the final release of iOS 12, which will be this September. Siri Shortcuts learns from the regularly actions a user takes. For example:
By adding the shortcut, Siri can make suggestions to the user based on their previous order history. For example, say the user likes to order tomato soup every Monday around noon. After placing this order a few times using Soup Chef, Siri learns the user’s pattern, and can use that information to predicate when the user might place a similar order. On the following Monday, Siri suggests to the user that they might want to order a bowl of tomato soup from Soup Chef.
