Answer 1

The reason you cannot add it in the scheme is that these are only for the iOS system languages. Tamil is not an optional system language for iOS but you can still use it in the localisation. In the project localisation:

Go to the bottom of the list proposed and select 'other'. A new list will open and you can choose Tamil there.

from here in the project variables.

as an app language you'll need to implement a language chooser button. See the link in the comments or do the following, add a function:

func changeToLanguage(_ langCode: String) {
    if Bundle.main.preferredLocalizations.first != langCode {
        let message = NSLocalizedString("In order to change the language, the App must be closed and reopened by you.", comment: "")
        let confirmAlertCtrl = UIAlertController(title: NSLocalizedString("App restart required", comment: ""), message: message, preferredStyle: .alert)

        let confirmAction = UIAlertAction(title: NSLocalizedString("Close now", comment: ""), style: .destructive) { _ in
            UserDefaults.standard.set([langCode], forKey: "AppleLanguages")
            UserDefaults.standard.synchronize()
            exit(EXIT_SUCCESS)
        }
        confirmAlertCtrl.addAction(confirmAction)

        let cancelAction = UIAlertAction(title: NSLocalizedString("Cancel", comment: ""), style: .cancel, handler: nil)
        confirmAlertCtrl.addAction(cancelAction)

        present(confirmAlertCtrl, animated: true, completion: nil)
    }
} 

and call it from a button:

@IBAction func didPressChangeLanguageButton() {
        let message = NSLocalizedString("Change language of this app including its content.", comment: "")
        let sheetCtrl = UIAlertController(title: NSLocalizedString("Choose language", comment: ""), message: message, preferredStyle: .actionSheet)

        for languageCode in Bundle.main.localizations.filter({ $0 != "Base" }) {
            let langName = Locale.current.localizedString(forLanguageCode: languageCode)
            if languageCode != "(null)" {
                let action = UIAlertAction(title: NSLocalizedString(langName!, comment: ""), style: .default) { _ in
                self.changeToLanguage(languageCode) // see step #2
                }
                sheetCtrl.addAction(action)
            }
        }

        let cancelAction = UIAlertAction(title: NSLocalizedString("Cancel", comment: ""), style: .cancel, handler: nil)
        sheetCtrl.addAction(cancelAction)

        sheetCtrl.popoverPresentationController?.sourceView = self.view
        sheetCtrl.popoverPresentationController?.sourceRect = self.changeLanguageButton.frame
        present(sheetCtrl, animated: true, completion: nil)
    }
