A Language manager to handle changing app language without restarting the app.

First of all, remember to add the Localizable.strings to your project, after adding the Localizable.strings file, select it then go to file inspector and below localization press localize, after that go to PROJECT > Localisation then add the languages you want to support (Arabic for example), dialog will appear to ask you which resource file you want to localize, select just the Localizable.strings file.
 
Now, add a Text view and then add a text to it, for example "Hello !", then go to your Localizable.strings file expand it, you will find Localizable strings file for English and Arabic, for English enter this line with the string you used in the Text view that we just mentioned before
"Hello !" = "Hello !";
and for Arabic file :
"Hello !" = "مرحبا !";

After that in you need to wrap your main view with LanguageManagerView and pass the default language that your app will run first time

@main
struct ExampleApp: App {
  var body: some Scene {
    WindowGroup {
      // The default language when the app starts for the first time.
      // it can be the `deviceLanguage`, `ar`, `en`, or any language.
      LanguageManagerView(.deviceLanguage) {
        AppView()
          .transition(.slide) // The animation that will be happening when the language change.
      }
    }
  }
}

If you want to change the language you should change the selectedLanguage as below

struct LangaugeView: View {
  
  // MARK: - Properties
  
  @EnvironmentObject var languageSettings: LanguageSettings
  
  // MARK: - body
  
  var body: some View {
    VStack {
      Text("Select a language")
        .padding()
      Button("Arabic") {
        withAnimation {
          languageSettings.selectedLanguage = .ar
        }
      }
      .padding()
      Button("English") {
        withAnimation {
          languageSettings.selectedLanguage = .en
        }
      }
    }
  }
}
