Unified theming support in Combine with Swift can greatly enhance the user experience by providing a consistent design throughout your application. By leveraging Combine's reactive programming paradigm, you can create dynamic and responsive UI components that adapt to theme changes seamlessly. Below is an example of how to implement unified theming support using Combine.
// Example of unified theming support in Swift
import SwiftUI
import Combine
// Define a Theme struct
struct Theme {
var backgroundColor: Color
var textColor: Color
}
// Create a ThemeManager to handle theme changes
class ThemeManager: ObservableObject {
@Published var currentTheme: Theme
init(defaultTheme: Theme) {
self.currentTheme = defaultTheme
}
func changeTheme(to newTheme: Theme) {
currentTheme = newTheme
}
}
struct ContentView: View {
@EnvironmentObject var themeManager: ThemeManager
var body: some View {
VStack {
Text("Hello, World!")
.foregroundColor(themeManager.currentTheme.textColor)
.padding()
.background(themeManager.currentTheme.backgroundColor)
Button(action: {
themeManager.changeTheme(to: Theme(backgroundColor: .black, textColor: .white))
}) {
Text("Switch to Dark Theme")
}
}
.padding()
}
}
@main
struct MyApp: App {
let themeManager = ThemeManager(defaultTheme: Theme(backgroundColor: .white, textColor: .black))
var body: some Scene {
WindowGroup {
ContentView()
.environmentObject(themeManager)
}
}
}
