Operators

Arithmetic Operators

Basic Arithmetic

Swift supports basic arithmetic operators like addition (+), subtraction (-), multiplication (*), and division (/).

let sum = 5 + 3  // 8
let difference = 9 - 4  // 5

Modulo Operator

The modulo operator (%) gives the remainder of a division operation.

let remainder = 10 % 3  // 1

Comparison Operators

Swift provides operators for comparing values, such as equals (==), not equals (!=), greater than (>), and less than (<).

if age == 30 {
    print("You are 30 years old.")
}

Logical Operators

Logical operators like AND (&&), OR (||), and NOT (!) are used to combine multiple conditions.

if age > 18 && isCompleted {
    print("You are eligible.")
}

Conclusion

Operators in Swift are versatile and powerful, allowing you to manipulate and compare data effectively. Understanding how to use these operators is essential for writing efficient Swift code.
