Dynamic Type text style

Carl Hoefs

Xcode 12.5, macOS 11.4

Xcode is issuing a warning for every NSTextField in my GUI that has "Automatically Adjusts Font" enabled:
  Automatically Adjusts Font requires using a Dynamic Type text style

I need this enabled on those text fields, so I've tried using System, Body, and even Helvetica, but it still warns of needing a Dynamic Type text style. 

What is a Dynamic Type text style, and how do I specify it?
