Localization can go a long way towards increasing the sales of our apps. Users are browsing the App Store all over the world, and when they come across a neat looking app that's not translated into their language, they're very likely to keep on scrolling. Today we’ll check out a library called Localize-Swift from Roy Marmelstein that makes this process much nicer.

The first helpful addition Localize-Swift brings us is a better way to localize our strings:

searchBar.placeholder = "Hello World".localized()

Then we can easily test our translations at runtime using:


We can respond to language changes using an NSNotification:

  selector: "setText",
  name: LCLLanguageChangeNotification, 
  object: nil

Localize-Swift also provides a custom genstrings.py script to easily fill our .strings files even though we're not using NSLocalizedString directly, neat!
