how to parse string array with SwiftyJSON?

Question

Using SwiftyJSON how would I parse the following JSON array into a Swift [String]?

{
    \"array\": [\"one\", \"two\", \"three\"]
}

SwiftyJSON lets you extract a String? using $0.string or a non optional String using stringValue with a default empty String value if the type doesn't match.

If you want to be sure to have an array of String with non false positives, use :

var stringArray = self.json["array"].array?.flatMap({ $0.string })

or in Swift 4.1

var stringArray = self.json["array"].array?.compactMap({ $0.string })

You can also replace self.json["array"].array by self.json["array"].arrayValue to have a [String] result instead of [String]?.
