Operators in Swift, In computer programming, operators are constructs defined within programming languages that behave generally like functions, but which differ syntactically or semantically. Common simple examples include arithmetic, comparison, and logical operations.

An operator is a symbol that tells the compiler to perform specific mathematical or logical manipulations.

- Arithmetic operators
- Assignment Operators
- Comparison Operators
- Logical Operators
- Bitwise Operators

## Arithmetic Operators

Arithmetic operators are used to performing mathematical operations like addition, subtraction, multiplication, etc.

Operator | Operation |

+ | Addition |

– | Subtraction |

* | Multiplication |

/ | Division |

% | Modulo |

```
#Example
var a = 7
var b = 2
// addition
print (a + b)
// subtraction
print (a - b)
// multiplication
print (a * b)
```

## Assignment Operators

Assignment operators are used to assign values to variables.

Operator | Example |

= | C = A + B will assign value of A + B into C |

+= | C += A is equivalent to C = C + A |

-= | C -= A is equivalent to C = C – A |

*= | C *= A is equivalent to C = C * A |

/= | C /= A is equivalent to C = C / A |

%= | C %= A is equivalent to C = C % A |

<<= | C <<= 2 is same as C = C << 2 |

>>= | C >>= 2 is same as C = C >> 2 |

&= | C &= 2 is same as C = C & 2 |

^= | C ^= 2 is same as C = C ^ 2 |

|= | C |= 2 is same as C = C | 2 |

```
#Example
// assign 10 to a
var a = 10
// assign 5 to b
var b = 5
// assign the sum of a and b to a
a += b // a = a + b
print(a)
```

## Comparison Operators

Comparison operators compare two values/variables and return a boolean result: true or false.

Operator | Meaning |

== | Is Equal To |

!= | Not Equal To |

> | Greater Than |

< | Less Than |

>= | Greater Than or Equal To |

<= | Less Than or Equal To |

```
#Example
var a = 5, b = 2
// equal to operator
print(a == b)
// not equal to operator
print(a != b)
// greater than operator
print(a > b)
// less than operator
print(a < b)
// greater than or equal to operator
print(a >= b)
// less than or equal to operator
print(a <= b)
```

## Logical Operators

Logical operators are used to check whether an expression is true or false. They are used in decision-making.

Operator | Example |

&& | a && b |

|| | a || b |

! | !a |

```
// logical AND
print(true && true) // true
print(true && false) // false
// logical OR
print(true || false) // true
// logical NOT
print(!true) // false
```

## Bitwise Operators

In Swift, bitwise operators are used to performing operations on individual bits.

Operator | Description |

& | Binary AND |

| | Binary OR |

^ | Binary XOR |

~ | Binary One’s Complement |

<< | Binary Shift Left |

>> | Binary Shift Right |

## Misc Operators

Here’s a list of other operators available in Swift.

Operator | Example |

? : | (5 > 2) ? “Success” : “Error” // Success |

?? | number ?? 5 |

… | 1…3 // range containing values 1,2,3 |
