In SwiftUI, persisting user preferences can be managed through UserDefaults, which allows you to save small amounts of data that are accessible throughout your app. Below is an example demonstrating how to use UserDefaults to save and retrieve user preferences.
import SwiftUI
struct ContentView: View {
@AppStorage("userPreference") private var userPreference: String = "Default Value"
var body: some View {
VStack {
Text("User Preference: \(userPreference)")
TextField("Enter your preference", text: $userPreference)
.textFieldStyle(RoundedBorderTextFieldStyle())
.padding()
}
.padding()
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
