How do I concatenate an array value to string in swift 3?

How do I join an array value to a string? I tried the following but got bad instruction error, appreciate any help. Sorry if my code looks bad as I'm still a student new to swift, hehe.

if let jsonData = try JSONSerialization.jsonObject(with: unwrappedData, options: .allowFragments) as? [String:Any] {
    if let test = jsonData["firstname"] as? String {
        let postString = "type=" + jsonData["firstname"] + "&type=insert"
    }
}

Try changing

let postString = "type=" + jsonData["firstname"] + "&type=insert"

to

let postString = "type=" + test + "&type=insert"

since you are assigning the non-nil value to test

Let me know if this helps!
