How do I handle theming and dark mode in Combine with Swift?

Handling theming and dark mode in Swift using Combine is essential for modern iOS applications. By leveraging Combine's reactive programming capabilities, you can create a responsive and user-friendly interface that adapts to the system's appearance settings.

Example Implementation

Below is an example of how to implement theming and dark mode support using Combine:

import SwiftUI import Combine // Theme model class Theme: ObservableObject { @Published var isDarkMode: Bool = false } struct ContentView: View { @ObservedObject var theme = Theme() var body: some View { VStack { Text("Hello, World!") .font(.largeTitle) .padding() Button("Toggle Theme") { theme.isDarkMode.toggle() } } .background(theme.isDarkMode ? Color.black : Color.white) .foregroundColor(theme.isDarkMode ? Color.white : Color.black) } }
