How to get detailed language of device in swift

Question

I have a database on the server that contains all the languages keywords that I use inside my applications and these languages could be changed any time.

In the language table of database there is column for Language (id , key, value, lang).

In the android application I read the language from device and it returns for example en-GB or en-US.

But in the iOS application I can't get the language like the above example , It always returns just the language (en , es, fr).

So I can't query to database to get the language specified keywords on the iOS application. Because the languages on the database is en-GB, en-US style.

var langId: String? = NSLocale.preferredLanguages().first as? String

How can I get the language with more details ?

No need an extra effort, just use the following as per your requirement.

Locale.current.identifier //en_US
Locale.current.collatorIdentifier //en-US
