Re: [Swig-user] Interfacing frontend with async C library

[William S F. <ws...@fu...>]

C# supports directors. Director support has not yet been added Javascript,
so it requires someone to contribute it. There is a part developed
Objective-C branch which requires someone to complete development before it
can be merged into SWIG master for incorporation into future SWIG releases.
It also does not have any director support. Unless you fancy getting
involved in SWIG development, you'll have to find another tool for these
last two languages or write the wrappers by hand.
