Usage

@Scriptable

Annotate your Swift classes with the @Scriptable macro to automatically generate a corresponding Python interface. For example:

@Scriptable
@Observable
class LoginViewModel {
    var username: String = ""
    var password: String = ""
    
    func login() {
        ...
    }
}

This will generate an equivalent type for Python:

class LoginViewModel:
    username: str
    password: str
    
    def login(self) -> None:
        ...

Integrating with SwiftUI

Inject the view model into Python using the interactable modifier:

struct LoginView {
    @State private var viewModel = LoginViewModel()
    
    var body: some View {
        viewImplementation
            .interactable("viewmodel", viewModel)
    }
}

After injection, Python scripts can interact with the Swift view model:

viewmodel = viewcontext.viewmodel
viewmodel.username = "username"
viewmodel.password = "password"
viewmodel.login()
