Last time we accidently introduced a bug where the selected pod details can be overwritten by our default pod.

Objectives

1. Fix Pod.default bug
2. Fix Preview
3. Fix Task reloading bug

Steps

Replace default

In PodDetailView.swift replace = Pod.default with : Pod.

Fix Preview

Load and decode get-pod.json, and pass it to our view.

struct PodDetailView_Previews: PreviewProvider {
    static var pod = File.data(from: "get-pod", withExtension: .json)?.toPod
    static var previews: some View {
        PodDetailView(pod: pod!)
    }
}

Delete Task

Delete task as we are passing the data from PodListView.swift.

	.task {
            if let response = await Network().getPod() {
                pod = response
            }
        }

PodDetailView.swift

import SwiftUI

struct PodListView: View {
    @State var pods: [Pod] = []

    var body: some View {
        NavigationView {
            List {
                ForEach(pods, id: \.self) { pod in
                    NavigationLink(destination: PodDetailView(pod: pod)) {
                        Text(pod.title)
                    }
                }
            }
            .navigationTitle(pods.isEmpty ? "Fetching Pods..." : "SpacePod")
            .task {
                if pods.isEmpty { await getPods() }
            }
            .refreshable {
                await getPods()
            }
        }
    }

    private func getPods() async {
        if let response = await Network().getPods() {
            pods = response
        }
    }
}

struct PodListView_Previews: PreviewProvider {
    static var pods = File.data(from: "get-pods", withExtension: .json)?.toPods
    static var previews: some View {
        PodListView(pods: pods!)
    }
}
