Found it!

It's a change behaviour starting from iOS 11.

Under iOS 11, [NSLocale currentLocale] only returns languages supported by your app’s localizations. If your app only supports English (as the base localization), then no matter what language the user selects on the device, currentLocale will always return English.

Under iOS 10 and earlier, currentLocale would directly represent the user’s chosen language and region, regardless of what localizations your app supports.
