How to call AWS Lambda functions in background within iOS

Within a native iOS app, what is the recommended way to call AWS lambda functions in the background when the app is not active? I have code that successfully calls lambda functions via the AWSLambdaInvoker object and I know how to use NSUrlSession to handle background requests to API endpoints that are not Lambda, but I'm not sure how to get the same behavior with AWSLambdaInvoker.
For example, the working code I have for calling Lambda functions follows this pattern:
let lambdaInvoker = AWSLambdaInvoker.default()
let params: [String: Any] = ["key1": "value1", "key2": 2, "key3": [1, 2]]
lambdaInvoker.invokeFunction("FUNCTION_NAME", jsonObject: params)
.continueWith(block: {(task:AWSTask<AnyObject>) -> Any? in
if( task.error != nil) {
print("Error: (task.error!)")
return nil
}
if let objects = task.result as? [[String:Any]] {
//process data...
}
return nil
})
What I'm unsure of is how to put this into a set of logic that can be run in the background like NSUrlSession.
