Localization in swift 3

step 1 : Add the Language

-->file will added like above image

Step - 2 : Add the String file

create String file and rename it as "Localizable.strings"

Step 3 : Configure String file for Localization

Step - 4 : Add the key values to get the value

note: we may check files are created in currect format or not by using cmds

1. cd into your project root
2. cd en.lproj - you can replace this with any localisation you are working with.
3. plutil -lint Localizable.strings

step - 5:

we can switch the language on buttons like

  @IBAction func english(_ sender: Any) {

        

        let path = Bundle.main.path(forResource: "en", ofType: "lproj")

        let bundel = Bundle.init(path:path!)! as Bundle

   countryName.text=bundel.localizedString(forKey: "usernametitle", value: nil, table: nil)

    }

    //pt-PT.lproj

    @IBAction func protual(_ sender: Any) {

        let path = Bundle.main.path(forResource: "pt-PT", ofType: "lproj")

        let bundel = Bundle.init(path:path!)! as Bundle

        countryName.text=bundel.localizedString(forKey: "usernametitle", value: nil, table: nil)

    }



change forResource string based on language
