while loops.. again

I am confused what is wrong here.. when i copy and paste this into Xcode it prints out 1-10. but in the practice it gives me this --You didn't println the right values. You printed [[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]] and we were looking for [1, 2, 3, 4, 5, 6, 7, 8, 9, 10].

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

var index = 9

while numbers.count > index {
println(numbers)
index++
}

When you're printing the numbers, you only want to print the numbers[index] which is increasing with each round.

println(numbers[index])

Also, you're starting your index at value 9 which the challenge really needs the value to start at 0 since it's looking for 1 through 10 inclusive to be printed.
