AWS get response as data, not JSON (for using with Codable) - swift

Question

Not familiar enough with AWS, but I have some Codable models I need to initialize from AWS. I'm getting JSON result from AWSTask.result (which is AnyObject). I'm trying to avoid creating Data from Dictionaty and back to a struct (to be able to use Codable).
I tied to use AWSNetworkingHTTPResponseInterceptor, but it was never got called and I couldn't find any example of using it.
self.getGatewayClient { (apiGatewayClient: AWSAPIGatewayClient?) in
let queryParameters = ...
let headerParameters = ...
apiGatewayClient?.invokeHTTPRequest(
"GET",
urlString: "/path",
pathParameters: [:],
queryParameters: queryParameters,
headerParameters: headerParameters,
body: nil,
responseClass: nil
).continueWith { (task: AWSTask<AnyObject>) -> Any? in
if let data = task... { // Get response as Data type??
}
if let result = task.result as? [String: Any] {
// Thanks, but I have a Codable, so I'll just take the data thank you.
}
return task
}
}

AWS's AWSAPIGatewayClient has two functions, one is: invokeHTTPRequest (which was what was used). There is another one called invoke, which returns data. It takes a AWSAPIGatewayRequest request:
func someTask(completion: #escaping (String?) -> ()) {
self.getGatewayClient { (apiGatewayClient: AWSAPIGatewayClient?) in
let request = AWSAPIGatewayRequest(httpMethod: "GET",
urlString: "/path",
queryParameters: queryParameters,
headerParameters: headerParameters,
httpBody: nil)
apiGatewayClient?.invoke(request).continueOnSuccessWith { response in
if let data = response.result?.responseData {
// Init Codable using data
}
}
}
}
