import SwiftUI

struct ContentView: View {
    @State private var stringArray: [String] = ["Apple", "Banana", "Orange"]
    
    var body: some View {
        VStack {
            Button("Save Array") {
                do {
                    let data = try PropertyListEncoder().encode(self.stringArray)
                    UserDefaults.standard.set(data, forKey: "StringArray")
                } catch {
                    print("Error encoding string array: \(error)")
                }
            }
            
            Button("Load Array") {
                if let data = UserDefaults.standard.data(forKey: "StringArray") {
                    do {
                        self.stringArray = try PropertyListDecoder().decode([String].self, from: data)
                    } catch {
                        print("Error decoding string array: \(error)")
                    }
                }
            }
