Leap Year in Swift

A leap year happens every four years, so it's a year that is perfectly divisible by four.

However, if the year is a multiple of 100 (1800, 1900, etc), the year must be divisible by 400 to be leap.

Write a function that determines if the year is a leap year or not.

Examples:

leapYear(2020) ➞ true

leapYear(2021) ➞ false

leapYear(1968) ➞ true

leapYear(1900) ➞ false
