Reference Resource in SwiftUI - swiftui

Question

I am trying to reference a JSON list in the Resources group from a SwiftUI view, but it won't work for some reason. Here is the code in ContentView.swift:
import SwiftUI
struct ContentView: View {
var kitten : Kitten
let stuff = ["this","that","these"]
#State private var i = 0
var body: some View {
VStack{
Text("Placeholder")
Button(action: {
self.i = (self.i+1)%3
// Do something
}) {
Text(stuff[i])
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView(kitten:kittens[0])
}
}
and my directory structure looks like this:
Project\
AppleDelegate.swift
SceneDelegateView.swift
ContentView.swift
Models\
Kitten.swift
Resources\
kittens.json
along with the other boiler plate stuff. I thought that if I had kittens.json in the Resources group that I would be able to reference it in the ContentView.swift file, no?

Answer 1

No, you have to load it explicitly using Bundle, like below
String(contentsOf: Bundle.main.url(forResource: stuff[i], withExtension: "json"))

Answer 2

The best way to handle json files is to add them in your Assets, as a Data Set:
1- Open your Assets.xcassets.
2- You create a New Data Set and give it a name like "kittens"
3- Drag & drop your json file into that new Data Set
4- You can access your data like this:
guard let assets = NSDataAsset(name: "kittens") else {
print("Missing data asset: kittens")
}
let kittens = try! JSONDecoder().decode([kitten].self, from: assets.data)
