I tried to found out the right solution for myself. When I use Locale.preferredLanguages.first was returned the preferred language from your app settings.

If you want get to know language from user device settings, you should the use string below:

Swift 3

let currentDeviceLanguage = Locale.current.languageCode
// Will return the optional String

To unwrap and use look at the line below:

if let currentDeviceLanguage = Locale.current.languageCode {
    print("currentLanguage", currentDeviceLanguage)

    // For example
    if currentDeviceLanguage == "he" {
        UIView.appearance().semanticContentAttribute = .forceRightToLeft
    } else {
        UIView.appearance().semanticContentAttribute = .forceLeftToRight
    }
}
