"sign" = "साइन इन करें";
"continue" = "जारी रखें";

and similar content in each localisation file with their translation

12. add the below extension in your code :

extension String {
  func localizeString(string: String) -> String {
    
      let path = Bundle.main.path(forResource: string, ofType: "lproj")
      let bundle = Bundle(path: path!)
      return NSLocalizedString(self, tableName: nil, bundle: bundle!, 
      value: "", comment: "")
  }

}

13. now you can use this extension to display the localised content as
    below.

let langCode = "en"
yourLbl.text = "sign".localizeString(string: langCode)

14. you have to change the value langCode and pass that value to the localizeString and change the translation according to that file.
