I’m trying to build a detail view screen where a user can edit the contents of an object and save it, but I’m struggling to figure out how best to initialize the view. I’m passing in a “MailFilter” object (which I decoded from a web API) to this view (from a List item’s NavigationLink), and am creating state for each of the fields which need to be editable, such that I can use them with a SwiftUI form. I have a custom initializer to set these parameters (and make sure they aren’t nil—as they can be in the actual filter object). struct FilterView: View { var filter: MailFilter @State var from: String @State var to: String init(_ filter: MailFilter) { self.filter = filter from = filter.criteria.from ?? "" to = filter.criteria.to ?? "" } var body: some View { Form { Section(header: Text("From")) { TextField("From", text: $from) } Section(header: Text("To")) { TextField("To", text: $to) } } } } However, this approach doesn’t seem to work. I’m given errors that I’m trying to use self. before initializing the variables—in the initializer! Is there a different approach I should be taking to get my object’s data into this detail view?
