How can I pass an object as an input to a method?

[karaggeorge]

Thank you so much for this project! It's been amazing so far. I'm reading through old issues and learning how to use all the different patterns. This is something I haven't found an example for yet:

I have a struct like:

struct Options {
	let destination: String
	let framesPerSecond: Int
	let cropRect: CGRect?
}

I'd like to expose a function that can take an object from js as input that has this shape, and then somehow type-cast it in Swift to use it as the struct

So I could for example do options.destination
