I already searched the internet for this, but I couldn't find a complete answer.I have an app with favorites. I want to save these favorites after closing the app.To save the changed data, one can work with Userdefaults.I have the following codeList {
Toggle(isOn: $userData.showFavoritesOnly) {
Text("show favorites").bold().underline()
}In another fileimport Foundation
class SettingsViewModel: ObservableObject {
@Published var isOn: Bool = UserDefaults.standard.bool(forKey: "isOn") {
didSet {
UserDefaults.standard.set(self.isOn, forKey: "isOn")
}
}
}Any help is appreciated.

I have the following code in my mainview:var body: some View {
NavigationView {
List {
NavigationLink(destination: CategoryoneList()) {
Text("1. ")
}
NavigationLink(destination: CategorytwoList()) {
Text("2. ")
}
NavigationLink(destination: CategorythreeList()) {
Text("3. ")
}
NavigationLink(destination: CategoryfourList()) {
Text("4. ")
}
NavigationLink(destination: CategoryfiveList()) {
Text("5. ")
}
NavigationLink(destination: CategorysixList()) {
Text("6. ")
}
NavigationLink(destination: CategorysevenList()) {
Text("7. ")
}
NavigationLink(destination: CategoryeightList()) {
Text("8. ")
}
NavigationLink(destination: MainList()) {
Text("9. ").bold().underline()
}
logo()
}.navigationBarTitle("Overzicht", displayMode: .inline)
.navigationViewStyle(DefaultNavigationViewStyle())
.padding(0)
}
}Now I want to add my ContactView (with mailadress and whatsApp) under my logo.The problem is that my ContactView is not displayed or I get the error "Argument passed to call that takes no arguments" next to my first NavigationLink.I already tried to put the different views in a VStack seperately, but with no result (first view with my list is not fully displayed).I don't want to work with scrollview, because I want my whole list with navigationlinks fully visible.
I have a detailed json file, where I have the following structure:struct legal: Hashable, Codable, Identifiable { var name: String var place: String var category: Category enum Category: String, CaseIterable, Codable, Hashable { case categoryone = "category One" case categorytwo = "category Two" case categorythree = "category Three" }}Now I want the list of all the names of the category one in one list. How do I extract the data from this file?
