How to toggle the app from RTL to LTR in SWIFTUI

Problem
How to implement LTR to RTL in SwiftUI

How you fix it
In SwiftUI the process of adding localization is similar to the way we do in UIKit but the challenge appears when when we need to switch the app 
from LTR to RTL since Arabic is written from RTL unlike other languages. So what we do is that we maintain an app state which will help us in toggling
the UI.   

Solution
1. Create an AppSate singleton class which will conform ObservableObject and will have a boolean check which will be used for toggling.

  class AppState: ObservableObject {
      static let shared = AppState()

      @Published var isRTL = false
  }

2. In our @main class we will set environment variable for the starting point of our app.

@main
struct DemoApp: App {
    private var language = LocalizationService.shared.language
    @ObservedObject var appState = AppState.shared
    
    init() {
        appState.isRTL = language == .english_us ? false : true
    }
    
    var body: some Scene {
        WindowGroup {
            Login().id(appState.isRTL)
                .environment(\.layoutDirection, appState.isRTL ? .rightToLeft : .leftToRight)
        }
    }
}

3. In our Login class we will start place the business logic for toggling between RTL and LTR. Within this view we will place a button and switch 
the boolean "isRTL" AppState.

  Button("Toggle Language") {
      if AppState.shared.isRTL {
          AppState.shared.isRTL = false
      } else {
          AppState.shared.isRTL = true
      }
  }
