Hello. I have a picker that uses an enum to populate itself. There is a class called "user" that has a variable called "defaultTab". This is what's being used as the selection for the picker.

Code Block enum Tab: String, CaseIterable {
    case data = "Data"
    case transactions = "Transactions"
    case user = "User"
    var id: String {self.rawValue}
}

That is the enum.

Code Block import SwiftUI
class User: ObservableObject {
    var name: String
    var sources: [Source]
    var accounts: [Account]
    var categories: [Category]
    var transactions: [Transaction]
    var defaultTab: Tab
    init(name: String, sources: [Source], accounts: [Account], categories: [Category], transactions: [Transaction], defaultTab: Tab) {
        self.name = name
        self.sources = sources
        self.accounts = accounts
        self.categories = categories
        self.transactions = transactions
        self.defaultTab = defaultTab
    }
}

That is the class, and below is the picker.

Code Block Picker("Default tab", selection: $user.defaultTab) {
                        ForEach(Tab.allCases, id: \.self) { kind in
                            Text(kind.rawValue)
                                .tag(kind as Tab)
                        }
                    }

This picker is inside of a Section that is inside of a List. When I make a selection, it does not change the picker. How can I resolve this issue?

If you could show complete code to reproduce the issue, more readers would try to solve it.
