I get the error swift_lint.swift:8:7: error: use of unresolved identifier 'index' while index > numbers.count {

Swift

while_loops.swift 
let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
while index > numbers.count {
println(numbers[index])
index++
}

Either set index as a variable and set it to something (0).

Or use a for..in loop for each in numbers { println(each[number]) } each could be anything... index, number, n...etc. But you need to specify that index is a var and that it starts at 0.
