Swift Loops: `repeat-while`

This tutorial belongs to the Swift series

A repeat-while loop in Swift is similar to the while loop, but in this case the condition is checked at the end, after the loop block, so the loop block is executed at least once. Then the condition is checked, and if it is evaluated as true, the loop block is repeated:

repeat {
    //statements...
} while [condition]

Example:

var item = 0
repeat { //repeats 3 times
    print(item)
    item += 1
} while item < 3
