How to get current language code with Swift?

Question

I want get the language code of the device (en, es...) in my app written with Swift. How can get this?

I\'m trying this:

var preferredLanguages : NSL         


        

Answer 1

Swift 5.3:

let languagePrefix = Locale.preferredLanguages[0]
print(languagePrefix)

Answer 2

In Swift 3

let langStr = Locale.current.languageCode

Answer 3

It's important to make the difference between the App language and the device locale language (The code below is in Swift 3)

Will return the Device language:

let locale = NSLocale.current.languageCode

Will return the App language:

let pre = Locale.preferredLanguages[0]

Answer 4

you may use the below code it works fine with swift 3

var preferredLanguage : String = Bundle.main.preferredLocalizations.first!

Answer 5

In Swift 3:

NSLocale.current.languageCode

Answer 6

Swift 3 & 4 & 4.2 & 5

Locale.current.languageCode does not compile regularly. Because you did not implemented localization for your project.

You have two possible solutions

1) String(Locale.preferredLanguages[0].prefix(2)) It returns phone lang properly.

If you want to get the type en-En, you can use Locale.preferredLanguages[0]

2) Select Project(MyApp)->Project (not Target)-> press + button into Localizations, then add language which you want.
