ios – JSON from URL Into Struct into Observable Object

I am studying to create my first app right here and have watched a number of YouTube tutorials I am struggling to merge collectively. Any assistance is a lot appreciated. After years of tutorials in varied programming languages, I am lastly coding one thing and sticking with it!

I simply can not grasp what I have to do to the code under and what I have to placed on one other view to permit me to name Restaurant.latitude and Restaurant.longitude.

I’m simply making an attempt to learn the lat/lengthy’s of all of the Eating places within the listing on my MapScreen vs the DashboardScreen. These are each Baby views to a MainView which is the mum or dad view to all logged in customers.

DashboardScreen – please notice I edited this easier. Simply belief that my stacks and layouts work. merchandise.identify, merchandise.latitude, and merchandise.longitude all pull from my JSON and show within the view with out error. After I go to MapScreen, I need to have the ability to name these merchandise.lat/longs or Restaurant.lat/lengthy to consumer in my pins. I’ve all of that discovered, simply want the information accessible to be learn.

import SwiftUI

struct Restaurant: Decodable {
    let id: String
    let identify: String
    let latitude: Double
    let longitude: Double
}

struct DashboardScreen: View {

    @State var eating places = [Restaurant]()
    
    var physique: some View {
        NavigationView {
             RestaurantList
        } // NavigationView
    } // Finish Physique
    
    func loadData() {
        guard let url = URL(string: "https://jsonfile.com/restaurantList.json") else {
            print("Invalid URL")
            return
        } // Load Knowledge
        
        let request = URLRequest(url: url)
        
        URLSession.shared.dataTask(with: request) {information, response, error in
            if let information = information {
                let decoder = JSONDecoder()
                decoder.dateDecodingStrategy = .iso8601
                if let decodedResponse = attempt?
                    decoder.decode([Restaurant].self, from: information) {
                    DispatchQueue.essential.async {
                        self.eating places = decodedResponse
                    }
                    return
                }
            }
            print("Fetch failed: (error?.localizedDescription ?? "Unknown error")")
        }.resume()
    }
}

non-public extension DashboardScreen {
    
    non-public var RestaurantList: some View {

        Checklist {
            ForEach(eating places, id:.id) { merchandise in
                NavigationLink(vacation spot: particulars(merchandise: merchandise)) {
                    HStack {
                            Textual content(merchandise.identify)
                            HStack {
                                Textual content(merchandise.latitude)
                                Textual content(merchandise.longitude)
                            }
                    } // HStack
                } // Label
            } // ForEach
        } // Checklist
        .onAppear(carry out: loadData)
