Swift: Logical Operators

Logical Operators in Swift:

A logical operator in swift is a symbol or phrase used to check, change or combine values. The addition operator (+) adds two numbers, such as let I = 1 + 2, and the logical AND operator (&&) combines two Boolean values, such as if enteredDoorCode && passedRetinaScan.

Swift supports operators you may be familiar with from other languages, such as C. Swift enhances a number of capabilities to eliminate common coding errors. To avoid being mistakenly used when the equal to operator (==) is intended, the assignment operator (=) does not return a value. To avoid unexpected results when working with numbers that become larger or smaller than the allowed value range of the type that stores them, arithmetic operators (+, -, *, /, percent, and so on) detect and disallow value overflow. So, you can enable value overflow behaviour using Swift’s overflow operators, as described in Overflow Operators.
