% is the remainder operator

so if 10 / 2 = 5 the remainder operator basically does the same thing but it returns the remainder instead of the actual answer ex. 10 % 2 = 0 or 10 % 3 = 1

It gives you the remainder of two numbers. For example: 10 % 2 = 0 So 10 divided by 2 is 5 with a remainder of zero. You could use this to select only even or odd numbers of a range using bool for example.

Throw this into a playground to see what I mean. Since I entered 100 as the Int when I called the function it prints "Even".

func oddOrEven(n: Int) -> String { if n % 2 == 0 { print("Even") } else { print("Odd") } return "((n))" }

oddOrEven(100)
