Using the new Encodable based API, you can get the string version of a JSON file using String(init:encoding) initialiser. I ran this in a Playground and the last print statement gave me

json {"year":1961,"month":4}

It seems that the format uses the minimum number of characters by detail.

struct Dob: Codable {
    let year: Int
    let month: Int
}

let dob = Dob(year: 1961, month: 4)
print("dob", dob)

if let dobdata = try? JSONEncoder().encode(dob) {
    print("dobdata base64", dobdata.base64EncodedString())
    if let ddob = try? JSONDecoder().decode(Dob.self, from: dobdata) {
        print("resetored dob", ddob)
    }
    if let json = String(data: dobdata, encoding: .utf8) {
      print("json", json)
    }
}
