How do I debounce text input in SwiftUI with Swift?

import SwiftUI
import Combine

struct DebounceExample: View {
    @State private var searchText: String = ""
    @State private var debouncedText: String = ""
    private var cancellable: AnyCancellable?

    var body: some View {
        VStack {
            TextField("Search...", text: $searchText)
                .padding()
                .textFieldStyle(RoundedBorderTextFieldStyle())
            
            Text("Debounced Text: \(debouncedText)")
                .padding()
        }
        .onAppear {
            setupDebounce()
        }
    }
    
    private func setupDebounce() {
        cancellable = $searchText
            .debounce(for: .milliseconds(300), scheduler: RunLoop.main)
            .removeDuplicates()
            .sink { value in
                debouncedText = value
            }
    }
}

struct DebounceExample_Previews: PreviewProvider {
    static var previews: some View {
        DebounceExample()
    }
}
