could you show how you use these, and where/what line you get the error. In other words show the surrounding context of this code. Is this in a View, in a function, etc...?

Concur, you do not show enough of your code. So I can only guess at your issues. You use ContentView(orchard: Orchard[0]) in ContentView_Previews, note carefully the uppercase Orchard[0]. This is wrong, Orchard is a type not an instance and not an array. It should at least be lowercase, orchard[0]. The other error you get is because you have "var orchard: Orchard " outside of any function or View or class. You cannot declare a variable without initialising, if it's not part of a class/struct etc..

As a simple workaround, you could try this: struct DecimalBindingView: View { @State private var txt = "" .... TextField("Input a number of type decimal…", text: $txt) .onChange(of: txt) { val in if let dec = Double(val) { model.decimalQuantity = Decimal(dec) } } ... }

add .multilineTextAlignment(.leading) to your VStack or Text(...)

Your code seems to work for me on macos 12.1beta, xcode 13.1, targets ios 15 and MacCatalyst macos 12. Tested on real devices, iPad and Mac. Here is my test code: import SwiftUI @main struct TestApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { var body: some View { NavigationView { List { NavigationLink(destination: ExploreView()) { Label("Explore", systemImage: "rectangle.3.group") } NavigationLink(destination: Text("ListView")) { // <-- for testing Label("Devices", systemImage: "list.bullet.below.rectangle") } } .listStyle(.sidebar) .navigationTitle("Orchard") ExploreView() } } } // for testing struct ExploreView: View { var body: some View { ZStack { Color.pink.ignoresSafeArea() Label("Devices", systemImage: "list.bullet.below.rectangle").foregroundColor(.white) } } }

adding .frame(height: 60) to each VStack works for me on macos 12.1 beta.

Make your getHomeItems() with a closure when done, and try something like this: .onAppear { self.showLoading = true DispatchQueue.main.async { store.getHomeItems() { _ in // <--- here self.showloading = false // <--- here } } ... }

try adding .navigationViewStyle(.stack) to your NavigationView

Try this code, works for me. struct ContentView: View { @State private var results = [DictionaryWord]() var body: some View { VStack { Text("API Example iOS Application") List(results) { item in VStack(alignment: .leading) { Text(item.word).font(.headline) ForEach(item.phonetics) { phone in // <--- here if phone.text != nil { Text(phone.text!) } } } } } .task { await loadData() } } let freeDictionaryURL = "https://api.dictionaryapi.dev/api/v2/entries/en/hello" func loadData() async { guard let url = URL(string: freeDictionaryURL) else { print("Invalid URL") return } do { let (data, _) = try await URLSession.shared.data(from: url) // --- here let decoded: [DictionaryWord] = try JSONDecoder().decode([DictionaryWord].self, from: data) results = decoded } catch { print(error) // <--- important } } } struct DictionaryWord: Identifiable, Codable { // <--- here let id = UUID() let word: String let phonetics: [Phonetic] let meanings: [Meaning] let license: License let sourceUrls: [String] enum CodingKeys: String, CodingKey { case word, phonetics, meanings, license, sourceUrls } } struct License: Codable { let name: String let url: String } struct Meaning: Codable { let partOfSpeech: String let definitions: [Definition] let synonyms, antonyms: [String]? } struct Definition: Codable { let definition: String let synonyms, antonyms: [String]? let example: String? } struct Phonetic: Identifiable, Codable { // <--- here let id = UUID() let audio: String let sourceURL: String? let license: License? let text: String? enum CodingKeys: String, CodingKey { case audio case sourceURL = "sourceUrl" case license, text } }

You could use the ObservableObject directly, there is no need for anything else, it is made to be use like in this example code: struct ContentView: View { var body: some View { BottomSheetView() } } class Movie: ObservableObject{ @Published var name: String = "" @Published var director: String = "" @Published var stars: Double = 0.0 @Published var review: String = "" // no need for all the functions } struct BottomSheetView:View{ @StateObject var newMovie = Movie() var body: some View { VStack(alignment: .leading) { Text("Add Movie") .fontWeight(.bold) .font(.system(size:30)) .padding() TextField("Movie name", text: $newMovie.name) // <--- here, etc... TextField("Movie director", text: $newMovie.director) // for testing, print to the console Button("show me") { print("\n---> newMovie: \(newMovie.name) \(newMovie.director) \n") } } } }

With the first method you are changing the checkItems array directly using the index and all works well, but using an index is not a recommended way. To achieve the same with the second (preferred) method, you need to have a binding for the item to be able to change it. To have that, use ForEach($checkItems) { $item in ....}

use TextField("Age", value: $model.age, formatter: nf). See the docs for the differences between the two versions, TextField, in particular the text version does not take a formatter

try using "struct ValueWrapper { var value = true } " instead of nesting "ObservableObject". Assuming you have declared "@StateObject var viewModel = ViewModel()" in the ContentView parent.
