Convert "Any" array to String in swift 3

Question

Having this code:

let object = json as? [Any] {
    if let questionari=object["questionnarie"] as? [Dictionary<String, AnyObject>]{
}

Compiler (of course) says to me that I can't use a String's index while it's [Any]: I can't find the proper why to cast it as String.

If object is supposed to be an array then the next line won't compile. — vadian

Try this code-

if let object = json as? [String:Any] {
    if let questionari=object["questionnarie"] as? [Dictionary<String, AnyObject>]{
}

you can make componentsJoined string with "," from any array.

like one line code see bellow example:

let yourStringVar = NSArray(array:ANY_ARRAY_NAME).componentsJoined(by: ",")
