Tuples in Swift allows you to store multiple values in a single variable. Since we a representing multiple values as a single variable, it only really makes sense if the constituent parts are tightly connected.

Terminology

Data Types: A representation of the tyoe of data that can be processed, for example Integer or String

Tuple: A way in Swift to allow you to store multiple values in a single variable.
