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’s true, the loop runs again:

repeat {
    // statements...
} while condition

Example:

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