Lets understand how Localizations works in iOS, Now in order to localize with languages apps just replaces the existing english word with value it is provided in the required language.

There are three main steps for localization:

  1. Add Localizations in the project section
  2. Add the extension given below to all the string
  3. Add the Key:Value for languages in the Localizable file

For eg: For Hello in english -> नमस्ते in hindi just provide the value of Hello in the Localizable string folder.

//MARK: - Extension for Localization
extension String {
    func localized() -> String {
        return NSLocalizedString(self, tableName: "Localizable", bundle: .main, value: self, comment: self)

❓How to use extension

 // Outlets
 @IBOutlet weak var greetingsLabel: UILabel!
 // Assiging text

? Localizable File

  • To best way to make localization easy is by converting the native language text as key and its value as the required language translation.
"Hello" = "नमस्ते";

Similarly add values for every text for localization in the Localizable File.
