let json = JSONValue(dataFromNetworking)if let userName = json[0]["user"]["name"].string{
//Now you got your value
} |
And don't worry about the Optional Wrapping thing, it's done for you automatically

let json = JSONValue(dataFromNetworking)if let userName = json[999999]["wrong_key"]["wrong_name"].string{
//Calm down, take it easy, the ".string" property still produces the correct Optional String type with safety

let json = JSONValue(dataFromNetworking)["some_key"]["some_wrong_key"]["wrong_name"]
if json{
//JSONValue it self confirm to Protocol "LogicValue", with JSONValue.JInvalid produce false and others produce true
}else{
println(json)
//> JSON Keypath Error: Incorrect Keypath "some_wrong_key/wrong_name"
//It always tells you where your key starts went wrong
switch json{
case .JInvalid(let error):
//An NSError containing detailed error information
}
