swift - Difference between == and ===

Question

In swift there seem to be two equality operators: the double equals (==) and the triple equals (===), what is the difference between the two?

Answer 1

!== and === are identity operators and are used to determine if two objects have the same reference.

Swift also provides two identity operators (=== and !==), which you use to test whether two object references both refer to the same object instance.
