Localization request permission base on the application language not device language - ios

Question

Localization is working fine in my application. I want localization the permission dialog text messages. It is working fine with the device language changes but I want to change message according to my application language.
I have tried the following code
import UIKit
class LocalizeHelper: NSObject {
private var myBundle: Bundle? = nil
static let shared: LocalizeHelper = {
let instance = LocalizeHelper()
return instance
}()
override init() {
super.init()
// use systems main bundle as default bundle
myBundle = Bundle.main
}
func localizedString(forKey key: String) -> String {
return myBundle!.localizedString(forKey: key, value: "", table: nil)
}
// Converted with Swiftify v1.0.6331 - https://objectivec2swift.com/
func setLanguage(_ lang: String) {
// path to this languages bundle
let path: String? = Bundle.main.path(forResource: lang, ofType: "lproj")
if path == nil {
// there is no bundle for that language
// use main bundle instead
myBundle = Bundle.main
}
else {
// use this bundle as my bundle from now on:
myBundle = Bundle(path: path!)
// to be absolutely shure (this is probably unnecessary):
if myBundle == nil {
myBundle = Bundle.main
}
}
}
func getLanguage() -> String {
print("\(String(describing: myBundle?.bundlePath.last))")
//return myBundle!.bundlePath.last >> Error
return myBundle!.bundlePath.lastCharacter!
}
}
extension String {
public var lastCharacter: String? {
guard let aLast = self.last else {
return nil
}
return String(aLast)
}
}
I have surfed in StackOverflow but didn't find any solution. Any help shell we appreciated.

Your best bet is to save the application's language in the user defaults as a string for example and then when you take it out of user defaults parse it as a custom app language enum. If you don't have any app language save you can always fall through to the device language but prefer or override it with the app language in user defaults not being nil. Also preferably you should wrap your user defaults interactions with a user defaults manager that you access in your view controller.
So the suggested steps are:
create userdefualts manager
define language enum
implement setLanguage func language parameter
implement getLanguage func language output with device language or
english as guard return
