swift - How to tell if a variable is an array -

i have swift function accepts , want able take array of strings, array of ints, mixed array, or array of arrays, etc. can take string or int, etc, not in array.

so have this:

private func parse(parameter: any) { if parameter int { // int } else if (parameter float) || (parameter double) { // double } else if parameter string { // string } else if parameter bool { // bool } else if allow array = parameter as? [any] { // should grab arrays } else { assert(false, "unsupported type") // [string] ends here } }

but if phone call parse(["strings"]), assert raised. how can grab types of arrays?

edit - there confusion i'm trying accomplish. need homecoming string based on type, int -> "" , string -> "", array create recursive calls homecoming "..."

this post marked duplicate, other question javascript, not swift.

i found way that, utilize nsarray casting.

private func parse(x: any) { if allow o = x as? [any] { println("[any]") } if allow o = x as? [anyobject] { println("[anyobject]") } if allow o = x as? nsarray { println("nsarray") } } allow a: [any] = ["bar"] allow b: [anyobject] = ["bar"] allow c = ["foo", 3.14] parse(a) // ==> [any] parse(b) // ==> [anyobject], , nsarray parse(c) // ==> nsarray

it array containing values of any internally represented in nsarray. (but should able cast c [any]...? i'm suspecting it's bug.)
