iOS System Language does not change to Albanian or Macedonian

Hello, I’m trying to determine whether Albanian (sq) and Macedonian (mk) are supported as full system display languages on iOS. When I go to: Settings → General → Language & Region → iPhone Language Albanian and Macedonian are not available as system languages. However, both languages appear to have support in other parts of iOS. For example, Apple currently lists Albanian and Macedonian among the supported QuickType keyboard languages. 
https://www.apple.com/in/ios/feature-availability/?utm_source=chatgpt.com I have tested this behavior on: - iOS 16.7 - iOS 17.5 - iOS 26.6.1 - iOS 27.0.1 In all tested versions, I cannot change the iPhone system/display language to Albanian or Macedonian. I would like to clarify: 1. Are Albanian (sq) and Macedonian (mk) officially supported as iOS system/display languages? 2. If they are not supported, is there an official Apple documentation page listing the supported iOS system languages? 3. Is there any API or mechanism available to an app to determine whether a language is supported as a system UI language, as opposed to being supported only for keyboards or other language features? 4. Are there plans to add Albanian and Macedonian as full iOS system languages? I understand that app localization is separate from the iOS system language. Apple documentation explains that an app's localization is determined from the user's preferred languages and the localizations provided by the app. 
https://developer.apple.com/library/archive/qa/qa1828/_index.html?utm_source=chatgpt.com https://developer.apple.com/documentation/foundation/locale/preferredlanguages?changes=_11&utm_source=chatgpt.com I’m specifically asking about Apple's own iOS system UI, not localization of a third-party application. Expected: Selecting Albanian or Macedonian as the iPhone language should make the iOS system UI appear in that language, if the language is supported. Actual: Albanian and Macedonian cannot be selected as the iPhone's system/display language. Could someone from Apple confirm whether this is expected behavior and whether these languages are currently unsupported as full iOS system languages? Thank you.

To see which languages are supported for various features including System Language, please refer to: https://www.apple.com/ios/feature-availability/

Specifically, for UI Localization, it is covered here: https://www.apple.com/ios/feature-availability/#system-language-system-language

Hi there! As of iOS 27.0.1, the iOS system UI is not localized into Albanian or Macedonian. As you noted, specific features (e.g. keyboards) are supported in certain languages that the system UI is not localized into. You can use this API to check which languages the system supports. The same information is also available on this webpage.
