how to use more efficiently SWXMLHash and how to set the class that will receive the data properly?

Question

I\'m building a project for a train schedule app, and I\'m using an API that returns an XML file,to manipulate the data i\'m using the library called SWXMLHash.

I used the below code in the SWXMLHash playground and it works on my machine:

// you need to model the ETD element as that has the destination and etd elements
class Etd {
    var destination: String = ""
    var estimates = [String]()

    init(destination: String, estimates: [String]) {
        self.destination = destination
        self.estimates = estimates
    }
}

// each station has a collection of ETDs (per the XML)
class Station {
    var name : String
    var etds = [Etd]()

    init(withName name: String, etds: [XMLIndexer]){
        self.name = name

        for etd in etds {
            self.etds.append(Etd(
                destination: etd["destination"].element!.text!,
                estimates: etd["estimate"].all.map { $0["minutes"].element!.text! })
            )
        }
    }
}

var stationsTest = [Station]()

for elem in xml["root"]["station"] {
    var stations = elem["name"].element!.text!
    var stationPlaceHolder = Station(withName: stations, etds: elem["etd"].all)
    stationsTest.append(stationPlaceHolder)
}

Basically, it looks like what you were missing was the abstraction for the Etd class - a station doesn't contain a list of destinations, but a list of Etds. Each Etd then has both a destination and estimates by minute.
