How do I debounce text input in Combine with Swift?

import SwiftUI
import Combine

struct ContentView: View {
    @State private var searchText: String = ""
    private var cancellables = Set()

    var body: some View {
        VStack {
            TextField("Search...", text: $searchText)
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()
        }
        .onAppear {
            setupDebounce()
        }
    }

    private func setupDebounce() {
        $searchText
            .debounce(for: .milliseconds(300), scheduler: RunLoop.main)
            .sink { input in
                // Process the debounced input here
                print("Debounced input: \(input)")
            }
            .store(in: &cancellables)
    }
}
