NSLocale.current.language returning the wrong value

Question

When I change my language in iPhone settings it isn't reflected in NSLocale.current.language.

Is this because my app does not support Spanish? I would expect it to be reflected regardless. Ultimately I'm trying to get the ISO 639-1 (2-digit) region code for the users preferred language.

Code:

guard var preferredLanguage = NSLocale.preferredLanguages.first else { return }

for language in NSLocale.preferredLanguages {
    print("preferredLanguage: \(language)")
}

print("languageCode: \(NSLocale.current.languageCode)")
print("regionCode: \(NSLocale.current.regionCode)")

Output:

preferredLanguage: es-US
preferredLanguage: haw-US
preferredLanguage: en-US
languageCode: Optional("en")
regionCode: Optional("US")

I'm not clear on what you're asking. From the output I see your preferred language is "es-US". What did you change it to? — Ashley Mills, Apr 24 '18 at 15:02

Since iOS 11, NSLocale.current can only return languages supported by your app.

Thank you! I hadn't seen that it had changed in iOS 11. I wish they would change the functionality behind the scenes like that. – Jeremiah Apr 24 '18 at 15:14
