while some condition is true {
doSomething()
}
in this case we want to loop over an array of numbers and print each number out.
to do this we need a variable to store the current index of the array which will be incremented each time the loop runs, thus looping over every item in the array
then use a while loop to loop over each array as long as that index is less than the count of the array. this will be the condition.
inside the loop we print out the current index of the array and increment the index
let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
var index = 0
while index < numbers.count {
println(numbers[index])
index++
}
