My Code is Var Index = 0 While Index < numbers.count { println(Index) Index ++ }

Why an I getting an error? It says use "While loop"

let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
var [Index] = 0
 While Index < numbers.count {

Swift (and most programming languages) is case sensitive. So the compiler see While uppercase differently than while lowercase. It needs to be lowercase. Also while not strictly an error, it's convention to have variables start with lowercase, so Index should be index. This helps differentiate it from class names which typically start with uppercase.
