that is also appearing when I click the "I" button in the preview error banner
I am attempting to use the SwiftUI tutorial at https://developer.apple.com/tutorials/swiftui/building-lists-and-navigation (section 2)
here is the code for the view that the preview is "crashing" on:
import SwiftUI
struct LandmarkRow: View {
var landmark: Landmark
var body: some View {
HStack {
landmark.image
.resizable()
.frame(width: 50, height: 50)
Text("landmark.name")
Spacer()
}
}
}
struct LandmarkRow_Previews: PreviewProvider {
static var previews: some View {
LandmarkRow(landmark: landmarks[0])
}
}
Here is the code for the area it is having the problem:
import Foundation
var landmarks: [Landmark] = load("landmarkDelta.json")
func load<T: Decodable>(_ filename: String) -> T {
let data: Data
guard let file = Bundle.main.url(forResource: filename, withExtension: nil)
else {
fatalError("Couldn't find (filename) in main bundle.")
}
do {
data = try Data(contentsOf: file)
} catch {
fatalError("Couldn't load (filename) from main bundle:\n(error)")
}
do {
let decoder = JSONDecoder()
return try decoder.decode(T.self, from: data)
} catch {
fatalError("Couldn't parse (filename) as (T.self):\n(error)")
}
}
It is saying there is an error on line 17. Here is the line of code:
fatalError("Couldn't find (filename) in main bundle.")
Here is the code from the Tutorial:
import Foundation
var landmarks: [Landmark] = load("landmarkData.json")
func load<T: Decodable>(_ filename: String) -> T { let data: Data
guard let file = Bundle.main.url(forResource: filename, withExtension: nil)
else {
fatalError("Couldn't find \(filename) in main bundle.")
}
do {
data = try Data(contentsOf: file)
} catch {
fatalError("Couldn't load \(filename) from main bundle:\n\(error)")
}
do {
let decoder = JSONDecoder()
return try decoder.decode(T.self, from: data)
} catch {
fatalError("Couldn't parse \(filename) as \(T.self):\n\(error)")
}
}
does anyone know what's wrong and how to fix it?
