How to debounce TextField search in SwiftUI

Issue #876

Make a dedicate DebounceObject to debounce (or throttle). Then we can even observe with onChange on the debouncedText or just use it directly to sort

import Combine

public final class DebounceObject: ObservableObject {
    @Published var text: String = ""
    @Published var debouncedText: String = ""
    private var bag = Set<AnyCancellable>()

    public init(dueTime: TimeInterval = 0.5) {
        $text
            .removeDuplicates()
            .debounce(for: .seconds(dueTime), scheduler: DispatchQueue.main)
            .sink(receiveValue: { [weak self] value in
                self?.debouncedText = value
            })
            .store(in: &bag)
    }
}

struct SearchView: View {
    @StateObject var debounceObject = DebounceObject()

    var body: some View {
        VStack {
            TextField(text: $debounceObject.text)
            .onChange(of: debounceObject.debouncedText) { text in
                // perform search
            }
        }
    }
}
