Answer 1

This will probably give you what you want:

NSLocale *locale = [NSLocale currentLocale];

NSString *language = [locale displayNameForKey:NSLocaleIdentifier 
                                         value:[locale localeIdentifier]];

It will show the name of the language, in the language itself. For example:

Français (France)
English (United States)

Answer 2

Swift

To get current language of device

NSLocale.preferredLanguages()[0] as String

To get application language

NSBundle.mainBundle().preferredLocalizations[0] as NSString

Note:

It fetches the language that you have given in CFBundleDevelopmentRegion of info.plist

if CFBundleAllowMixedLocalizations is true in info.plist then first item of CFBundleLocalizations in info.plist is returned

Answer 3

In Swift 4.2 and Xcode 10.1

let language = NSLocale.preferredLanguages[0]
print(language)//en

Answer 4

According to Apple documentation

NSUserDefaults* defs = [NSUserDefaults standardUserDefaults];
NSArray* languages = [defs objectForKey:@"AppleLanguages"];
NSString* preferredLang = [languages objectAtIndex:0];

Two letters format. Apple uses the ISO standard ISO-3166.

NSString *localeCountryCode = [[NSLocale autoupdatingCurrentLocale] objectForKey:NSLocaleCountryCode];
