"paymentType":"DB",
"paymentBrand":"VISA",
"amount":"156.00",
"currency":"EUR",
"merchantTransactionId":"E8A39B31-6FA3-4014-A195-3074DF5BF7A1",
"result":{
	"code":"000.100.110",
	"description":"Request successfully processed in 'Merchant in Integrator Test Mode'"
},
"resultDetails":{
	"ConnectorTxID3":"12311312",
	"ConnectorTxID1":"717473"
},
"card":{
	"bin":"420000",
	"last4Digits":"0000",
	"holder":"Andreas",
	"expiryMonth":"12",
	"expiryYear":"2018"
},
"risk":{
	"score":"100"
},
"buildNumber":"4b471ea5366e5e9c9a21392a39769f8d7b40b4e8@2016-09-08 13:31:54 +0000",

    let json = CkoJsonObject()!

    // Load the JSON into the object.
    // Call json.Load to load from a string rather than a file...
    var success: Bool = json.loadFile("qa_data/json/merchantPayment.json")
    // We are assuming success..

    // Get the easy stuff:
    print("id: \(json.string(of: "id")!)")
    print("paymentType: \(json.string(of: "paymentType")!)")
    print("currency: \(json.string(of: "currency")!)")
    print("buildNumber: \(json.string(of: "buildNumber")!)")

    // Get information that's nested within a sub-object:
    print("result: code: \(json.string(of: "result.code")!)")
    print("result: description: \(json.string(of: "result.description")!)")

    print("card: bin: \(json.string(of: "card.bin")!)")
