While Loop

Can anyone explain and give me the correct code?

while_loops.swift 
let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

var index = 0

while index < numbers { 
    println(numbers)
}

Hello :

A while loop needs to have a condition that's true, and it will continue "looping" until that condition becomes false. 

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

var index = 0

while index < numbers.count {  //condition is true
    println(numbers) // we print 
    Index++ // add one more till it goes above 10 and condition becomes false and loop dies
}

I'm sorry if I can't go into more detail, I'm doing this on my phone.

Hope it helps
