Hello Jurgen:

“A while loop performs a set of statements until a condition becomes false” Excerpt From: Apple Inc. “The Swift Programming Language.” iBooks. https://itun.es/us/jEUH0.l

let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] // the array of numbers

var index = 0 // A variable with a value of 0

while index < numbers.count { // This condition is true
    println(numbers[index]) // We print the values each time the loop passes by
    index++ // we add one value each time the loop passes until is about 10
}
/*
So while index is below 10, the loop will print out each number, and since
index is being added ONE value each time the loop passes, index will
become higher than 10 and it will make the condition false, and 
the loop dies. 
*/

hope you understand , if need any more clarification please let me know.
