iOS 12 suggest phone number in QuickType bar

Question

How is Lyft suggesting my phone number in the QuickType bar so that I do not have to enter it manually? I know Apple introduced autofill functionality for usernames, passwords, security codes, and more with iOS 12 and it looks like this phone number suggestion may be using a similar function but I cannot figure out how to get any of my apps to suggest the phone number like Lyft is doing below.

From Interface Builder / Storyboard

• Select a textField.
• Show the Attributes inspector.

From Code

You can access this property in any UITextField

textField.textContentType = .telephoneNumber
