NSSpellServer class gives you a way to make your application’s spell checker available as a spelling service available to any application.
- macOS 10.10+
A service provider is an application that declares its availability in a standard way, so that any other applications that wish to use it can do so. If you build a spelling checker that makes use of the
NSSpellServer class and list it as an available service, then users of any application that makes use of
NSSpellChecker or includes a Services menu will see your spelling checker as one of the available dictionaries.
