A while loop can be used to iterate on anything, and will run while the condition is true:

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

The condition is checked at the start, before the loop block is executed.

Example:

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