SOLVED -- Day 60 Milestone Question

Forums > 100 Days of SwiftUI

Hello I have the following code which is returning a blank screen other than the temporary navigation title, any help would be appreciated:

import SwiftUI

struct User: Codable{
    struct Friend: Codable {
        let id: String
        let name: String
    }

    var id : String
    var isActive: Bool
    var name: String
    var age: Int
    var company: String
    var email: String
    var address: String
    var about: String
    var registered: Date = Date()
    var tags: [String] = []
    var friends: [Friend] = []
}

struct ContentView: View {
    @State private var users = [User]()

    var body: some View {
        NavigationStack {
            List(users, id: \.id) { user in
                VStack {
                    Text("User name: \(user.name)")
                }   // End VStack
            }   // End List
            .navigationTitle("Test Data")
            .task {
                await loadData()    // We attempt to load our data from the URL
            }
        }
    }   // end var body

    // Async function that retrieves data from the internet:
    func loadData() async {
        //  1. Create the URL we want to read:
        guard let url = URL(string: "https://www.hackingwithswift.com/samples/friendface.json")
        else {
            print("Invalid URL")
            return
        }

        //  2. Attempty to fetch data from URL:
        do {
            let(data, _) = try await URLSession.shared.data(from: url)
            //  3. If successful then we decode the result using the Response struct and then put the resulting decoded data into the results array of Users:
            if let decodedResponse = try? JSONDecoder().decode([User].self, from: data) {
                users = decodedResponse
            }
        } catch {
            print("Invalid data")
        }
    }   // End loadData() func
}   // End ContentView struct

#Preview {
    ContentView()
}

I made the following changes inside my loadData() function and the data started loading up:

func loadData() async {
    //  1. Create the URL we want to read:
    guard let url = URL(string: "https://www.hackingwithswift.com/samples/friendface.json")
    else {
        print("Invalid URL")
        return
    }

    //  2. Attempty to fetch data from URL:
    let decoder = JSONDecoder()
    decoder.dateDecodingStrategy = .iso8601

    do {
        let(data, _) = try await URLSession.shared.data(from: url)
        //  3. If successful then we decode the result using the Response struct and then put the resulting decoded data into the results array of Users:
        if let decodedResponse = try? decoder.decode([User].self, from: data) {   // [User] is how the data is formatted in the JSON file, in this case we have an array of User in the JSON file
            users = decodedResponse
        }
    } catch {
        print("Invalid data")
    }
}   // End loadData() func

Seems like what was missing was that dateDecodingStrategy :/
