(Swift 2) Iterate JSON where Member Names are Data Values

Demonstrates how to parse JSON where member names are not keywords, but instead are data values.

func chilkatTest() {
    let json = CkoJsonObject()

    var success: Bool = json.LoadFile("qa_data/json/valuesAsNames.json")

    // Imagine we have JSON such as the following:

    // {
    //   "1680": {
    //     "entity_id": "1680",
    //     "type_id": "simple",
    //     "sku": "123"
    //   },
    //   "1701": {
    //     "entity_id": "1701",
    //     "type_id": "simple",
    //     "sku": "456"
    //   }
    // }
    // 

    // This presents a parsing problem because the member names, such as "1680"
    // are not keywords.  Instead they are data values.  We don't know what they
    // may be in advance.  

    // To solve, we iterate over the members, get the name of each, ...
    var numMembers: Int = json.Size.intValue
    var i: Int
    for i = 0; i <= numMembers - 1; i++ {

        var name: String? = json.NameAt(i)

        print("\(name!):")
        var jRecord: CkoJsonObject? = json.ObjectAt(i)

        print("entity_id: \(jRecord!.StringOf("entity_id"))")
        print("type_id: \(jRecord!.StringOf("type_id"))")
        print("sku: \(jRecord!.StringOf("sku"))")

        jRecord = nil

    }
