Comparison Operators

You use comparison operators to compare two values. You can test for equality or whether one value is greater or less than another value.

Table 15-1 describes the comparison operators available in Swift.

Table 15-1. Comparison Operators

Operator	Description
x == y	Equal to
x != y	Not equal to
x > y	Greater than
x >=y	Greater than or equal to
x < y	Less than
x <= y	Less than or equal to
x === y	Two objects are equal
x !== y	Two objects are not equal

Note  The last two comparison operators in Table 15-1 (=== and !==) apply only to objects (see Chapter 32). Objects are also known as instances in Swift.

Comparison operators return a boolean result that you can store in a boolean variable or constant. See
