    let json = CkoJsonObject()!

    var jsonStr: String? = "{ \"id\": 1, \"name\": \"A green door\", \"tags\": [\"home\", \"green\"], \"price\": 125 }"

    var success: Bool = json.load(jsonStr)
    if success != true {
        print("\(json.lastErrorText!)")
        return
    }

    var numMembers: Int = json.size.intValue
    var i: Int
    for i = 0; i <= numMembers - 1; i++ {

        var name: String? = json.name(at: i)
        var value: String? = json.string(at: i)

        print("\(name!): \(value!)")

        var iValue: Int = json.int(at: i).intValue
        print("\(name!) as integer: \(iValue)")

    }

    // Note: The StringAt method returns the value as a string regardless of the type.
    // If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
    // of the entire array is returned.

    // The IntAt method returns the value as an integer.  If the value does not convert to 
    // an integer, then 0 is returned
