Compiler is stupid

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

var i = 0

while i < numbers.count {
    println(numbers[i])
}

Surprisingly, the above code won't compile

What do you mean it won't compile? It will compile but you probably won't see the result here because your loop is infinite loop. 'i' is not gonna increase by itself you know.

you need to add i++ because your loop is infinite loop 

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

var i = 0

while i < numbers.count {
    println(numbers[i])
    i++
}

i hope this helpful :)
