How to stringify JSON

This assumes you have SwiftyJSON.

Start with a Dictionary

let paramsDictionary = [
    "title": "foo",
    "description": "bar"
]

First convert a Dictionary to JSON

let paramsJSON = JSON(paramsDictionary)

Then convert the JSON to a string.

let paramsString = paramsJSON.rawString(encoding: NSUTF8StringEncoding, options: nil)
