Localization of String, Int, Float, etc (Swift)

Localization.swift

import Foundation

// Usage "String".localize will search for "String" key in Localizeble
// Works for all types that conform CustomStringConvertible protocol, e.g. Int, Float. 
// Raw value will be converted to string and used as key, e.g.
// 10.localize, will search for "10" key.
// If key not exists, then string value will be returned

extension CustomStringConvertible {
    var localize: String { 
        return NSLocalizedString(self.description, comment: "") 
    }
}
