Hi there, I'm still new on learning how to code, so I'm seeking some guidance on this problem. I'm trying to make a page that shows a list of employees, I get an error reading 'Instance member 'data' cannot be used on type 'Employee'; did you mean to use a value of this type instead?' Below is the code. // AllEmployees.swift import SwiftUI struct AllEmployees: View { let names = data.firstName // Error shows on the next line ↓ @State private var data = Employee.data @State private var searchText = "" var body: some View { NavigationStack { List { ForEach(data.firstName, id: \.self) { name in NavigationLink { Text(data.firstName) } label: { Text(name) } } } .searchable(text: $searchText) .navigationTitle("All Employees") } } var searchResults: [String] { if searchText.isEmpty { return names } else { return names.filter { $0.contains(searchText) } } } } struct AllEmployees_Previews: PreviewProvider { static var previews: some View { NavigationView { AllEmployees() } } } Any help is appreciated :)

Hello, I've completed the Landmarks App Apple Developer tutorial, since finishing it I decided to create a project using the .JSON code from the project. I've wrote the code in an identical layout as the tutorial, however I am receiving the error - Couldn't parse lesssonData.json as array - when trying to load a preview and the app builds successfully but crashes when I launch it. Below is the code, any help is appreciated! LessonList.swift import SwiftUI struct LessonList: View { var lesson: Lesson var body: some View { VStack { List { Section { ForEach(lessons, id: \.self) { lesson in Label(lesson.name, systemImage: "house") } } Section { Label("Hello World!", systemImage: "globe") } } } } } struct LessonList_Previews: PreviewProvider { static var lessons = ModelData().lessons static var previews: some View { LessonList(lesson: lessons[0]) } } ModelData.swift import Foundation import Combine final class ModelData: ObservableObject { @Published var lessons: [Lesson] = load("lessonData.json") } var lessons: [Lesson] = load("lessonData.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)") // Error on this Line } } lessonData.JSON [ { "id":"1001", "lessonNo":"Lesson 1", "name":"Introduction to Photography", "category":"Introduction", }, { "id":"1002", "lessonNo":"Lesson 2", "name":"Negative and Positive Space", "category":"Introduction", }, { "id":"1003", "lessonNo":"Lesson 3", "name":"Introduction to Camera Angles", "category":"Introduction", }, { "id":"1004", "lessonNo":"Lesson 4", "name":"Lighting and Framing", "category":"Beginners", }, { "id":"1005", "lessonNo":"Lesson 5", "name":"Still Photography", "category":"Beginners", }, { "id":"1006", "lessonNo":"Lesson 6", "name":"Motion Photograhy", "category":"Beginners", }, { "id":"1007", "lessonNo":"Lesson 7", "name":"Aperture and F-Stops", "category":"Intermiediate", }, { "id":"1008", "lessonNo":"Lesson 8", "name":"Shutter Speeds", "category":"Intermiediate", }, { "id":"1009", "lessonNo":"Lesson 9", "name":"Advanced Framing", "category":"Advanced", }, { "id":"1010", "lessonNo":"Lesson 10", "name":"Advanced Aperture, F-Stops and Shutter Speeds", "category":"Advanced", }, ]

I am creating a Medical App using SwiftUI. I am trying to make a treatment view that provides a different set of answers (fetched from a .json) based on the answer to a certain set of questions. I have tried this (see below) but I am experiencing errors with it. I figured it would be best to get some other opinions before diving down this rabbithole.
