Could you add support for Objective-C?

I see that C/C++ and Swift are supported, but our project still contains a significant amount of Objective-C code.

Objective-C support is feasible — there's a tree-sitter-objc grammar. Adding to the feature backlog. In the meantime, C and C++ headers are already parsed.

Objective-C support is a valid request. tree-sitter-objc is available in tree-sitter-language-pack. Key constructs: @interface/@implementation (classes), - and + method declarations (functions), #import (imports).

A PR adding .m/.h (with ObjC detection) support would be welcomed — though .h is shared with C/C++, so detection would need to be careful (perhaps requiring @interface or @implementation in the file content).
