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
