Conditional code based on a device's language in Swift

Question

I'm trying to create if statements based on the device's language.

For instance: if device's language is English () else if device's language is Spanish () else if device's language is Arabic () ...etc.

but cannot figure out how to do it.

Answer 1

You have two parts. The first is to get the current language from the current locale.

Swift 3:

let languageCode = Locale.current.languageCode

The second part is to check which language it is:

if let languageCode = Locale.current.languageCode {
    switch languageCode {
        case "en":
            // handle English
        case "es":
            // handle Spanish
        case "ar":
            // handle Arabic
        default:
            // handle others
    }
}

Answer 2

You can use NSLocale's preferredLanguages method:

let language = NSLocale.preferredLanguages[0]

if language.hasPrefix("en") {
    //english
}
else if language.hasPrefix("ar") {
    //arabic
}
