Replacement for AGSQueryTask in Quartz

Question

I noticed that AGSQueryTask is no longer available in Quartz. What is the preferred way to query for features on the server? If I create an AGSServiceFeatureTable and then call queryFeaturesWithParameters:completion: method will that run the query against the server or just the features that have been fetched so far?

With swift 3 the code would look like this to do a query against a ServiceFeatureTable. Make sure to hold a reference to the ServiceFeatureTable so that it doesn't go out of scope and get deallocd before the request is finished. sft = AGSServiceFeatureTable(url: URL(string: "https://sampleserver3.arcgisonline.com/ArcGIS/rest/services/SanFrancisco/311Incidents/FeatureServer/0")!) sft.featureRequestMode = .onInteractionNoCache let qp = AGSQueryParameters() qp.whereClause = "req_type = 'Sidewalk and Curb Issues'" sft.queryFeatures(with: qp, fields: .loadAll){ result, error in if let error = error { print("error querying: \(error)") } else{ print("result: \(result)") let enumerator = result?.featureEnumerator() while let feature = enumerator?.nextObject(){ print("feature: \(feature)") } } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
