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.
