Localizable.swift

protocol Localizable {

    static var tableName: String { get }
}

// MARK: - RawRepresentable

extension Localizable where Self: RawRepresentable, Self.RawValue == String {
    var localized: String {
        return rawValue.localized(bundle: .main, tableName: Self.tableName)
    }

    static var tableName: String {
        return String(describing: self)
    }
}

String.swift

extension String {
    func localized(bundle: Bundle, tableName: String) -> String {
        return NSLocalizedString(self, tableName: tableName, bundle: bundle, value: "**\(self)**", comment: "")
    }
}

enum Strings {
    // Mirror of: `Common.strings`
    enum Common: String, Localizable {
        case signInButton = "SIGN_IN"
    }

    // Mirror of: `Card.strings`
    enum Card: String, Localizable {
        case title = "TITLE"
        case description = "DESCRIPTION"
    }
