Force RTL or LTR in SwiftUI

You may one to make the app default language to some Right To Left like Persian in info.plist or with other methods:

If you need to force a view, Just apply this modifier on any view you like:

.environment(\.layoutDirection, .rightToLeft)

You can apply to the ContentView() in SceneDelegate to make it available for all subviews.

You can either set layout direction in the Scene Delegate:

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {        let contentView = ContentView().environment(\.layoutDirection, .rightToLeft)        if let windowScene = scene as? UIWindowScene {            let window = UIWindow(windowScene: windowScene)            window.rootViewController = UIHostingController(rootView: contentView)            self.window = window            window.makeKeyAndVisible()        }    }

or manually disable change of direction on some views using this modifier:

.flipsForRightToLeftLayoutDirection(true)

I tried everything to force SwiftUI to be RTL Arabic, Like...

import SwiftUI    @main    struct MyApp: App {        init() {            UserDefaults.standard.set(["ar"], forKey: "AppleLanguages")        }                var body: some Scene {            WindowGroup {                             ContentView()                    .environment(\.locale, Locale(identifier: "ar"))                    .environment(\.layoutDirection, .rightToLeft)            }        }    }

But this way cause a lot of bugs if you use NavigationViewThe best solution is...

import SwiftUI    @main    struct MyApp: App {        init() {            UserDefaults.standard.set(["ar"], forKey: "AppleLanguages")        }                var body: some Scene {            WindowGroup {                             ContentView()            }        }    }
