Description
[iOS] Non-public API usage - The app references non-public symbols in XXX: _locale_charset. If method names in your source code match the private Apple APIs listed above, altering your method names will help prevent this app from being flagged in future submissions. In addition, note that one or more of the above APIs may be located in a static library that was included with your app. If so, they must be removed. email from App Store Connect

Expected behavior
The static libraries libiconv.framework/libiconv and libcharset.framework/libcharset contains '_local_charset' API which is in conflict with the non public symbols from Apple API and in my opinion should be renamed.

Current behavior
The static libraries libiconv.framework/libiconv and libcharset.framework/libcharset contains '_local_charset' API which is in conflict with the non public symbols from Apple API. As result, app cannot be released nor distributed to Apple App Connect.
