Swift supports the operators you may already know from languages like C, and improves several capabilities to eliminate common coding errors. The assignment operator ( = ) doesn’t return a value, to prevent it from being mistakenly used when the equal to operator ( == ) is intended.
Type inference helps make Swift code more concise and readable when it initializes constants or variables with other values whose type is already known. Boolean values are particularly useful when you work with conditional statements such as the if statement:
