Unable to create Mock for method which has typed-throws in the signature

[dr-star]

Hello All!,

If a function signature uses the new Typed throws introduced with Swift 6, Cuckoo doesn't generate mocks properly.
For example I use throws(APIError) the file into GeneratedMocks.swift has only throws

import Foundation
import Factory

protocol RegistrationServiceProtocol {
    func registration(name: String, surname: String, email: String, password: String) async throws(APIError) -> UUID
}

class RegistrationService: RegistrationServiceProtocol {
    @Injected(\.registrationClient) var registrationClient: RegistrationClientProtocol
    
    func registration(name: String, surname: String, email: String, password: String) async throws(APIError) -> UUID {
        let request = UserRegistrationRequest(name: name, surname: surname, email: email, password: password)
        
        return try await registrationClient.register(request: request)
    }
}

The generate mock into "GeneratedMocks" doesn't have the " same signature as the interface, instead it has

override func registration(name p0: String, surname p1: String, email p2: String, password p3: String) async throws

with the following error Type 'RegistrationServiceProtocolStub' does not conform to protocol 'RegistrationServiceProtocol'

Hey, yeah, this isn't supported at the moment. I don't think we're using SwiftSyntax 6 yet, though after its integration adding support for this shouldn't be too hard generator-wise. Not sure about the runtime.
