Swift (as of December 3, 2020)

func jsonToString(json: AnyObject){
    do {
        let data1 =  try JSONSerialization.data(withJSONObject: json, options: JSONSerialization.WritingOptions.prettyPrinted) // first of all convert json to the data
        let convertedString = String(data: data1, encoding: String.Encoding.utf8) // the data will be converted to the string
        print(convertedString ?? "defaultvalue")
    } catch let myJSONError {
        print(myJSONError)
    }
    
}
