51.1 Modifying the Weather Data

Before adding configuration support to the widget, an additional structure needs to be added to the widget data to provide a way to associate cities with weather timelines. Add this structure by modifying the WeatherData.swift file as follows:

import Foundation

import WidgetKit

 

struct LocationData: Identifiable {

    

    let city: String

    let timeline: [WeatherEntry]

    

    var id: String {

        city

    }

    

    static let london = LocationData(city: "London",

                                 timeline: londonTimeline)
