I'm not sure how Nim/Obj-C interop works, but if it's difficult to emit an `@interface` and `@implementation` at compile-time, an alternative is to create the class at runtime using the C API in `<objc/objc-runtime.h>`. It's fairly easy to do; the trickiest part probably is that the methods need to be provided in the form of C functions that have `self` and `_cmd` parameters prepended. I have some experience using this API, and I'm glad to offer advice if it's desired.
