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:

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

📌 Localization Extension

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

📁 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.
