Usage

First of all remember to add the Localizable.strings to your project, after adding the Localizable.strings file, select it then go to file inspector and below localization press localize, after that go to PROJECT > Localisation then add the languages you want to support (Arabic for example), dialog will appear to ask you which resource file you want to localize, select just the Localizable.strings file.
 
Now, go to your storyboard and add UILable and add text to it, for example "Hello !", then go to your Localizable.strings file expand it, you will find Localizable strings file for English and Arabic, for English put just this line with the string you put in the UILabel inside the storyboard
"Hello !" = "Hello !";
and for Arabic file :
"Hello !" = "مرحبا !";

LanguageManger.shared.defaultLanguage = .en

If you want to change the language use the setLanguage(language:) method by passing to it the new language

@IBAction func changeLanguage(_ sender: UIButton) {

let selectedLanguage:Languages = sender.tag == 1 ? .en : .ar

// change the language
LanguageManger.shared.setLanguage(language: selectedLanguage)

// then you must to pop all view controllers and return to root view controller then re set the root view controller 
UIApplication.topViewController!.dismiss(animated: true) {
let delegate = UIApplication.shared.delegate as! AppDelegate
let storyboard = UIStoryboard(name: "Main", bundle: nil)
delegate.window?.rootViewController = storyboard.instantiateInitialViewController()
}
}

*Note
The language manager help you to support multiple languages in your app, However, there are some cases that you want to handle it yourself like some UILable or UITextField didn't change the direction, so you need to do that . Example:

textAlignment = LanguageManger.shared.isRightToLeft ? .right : .left.

Installation

Just add LanguageManger.swift in your project
