4 Arithmetic Operators in Swift
Swift supports the four standard arithmetic operators for all number types:
Addition (+)
Subtraction (-)
Multiplication (*)
Division (/)
Unlike the arithmetic operators in C and Objective-C, the Swift arithmetic operators don’t allow values to overflow by default. You can opt in to value overflow behavior by using Swift’s overflow operators (such as a &+ b). See Overflow Operators.
