Make the equivalent of koin-annotation in swift code. Leveraging custom swift attributes.

Is your feature request related to a problem? Please describe.
One of the techniques to consume third party SDKs in swift from kotlin, consist of:
1- Declare an interface in the kotlin side,
2- Then create a class in swift which conforms to the respective interface(protocol in swift). This class does the actual interaction with the third party SDK.
3- Then we provide these implementations to the koin container bridging the interface implementations typically using a helper class for this.

Another alternative is using global functions that serves as a factory but it kind of pollute the global scope and requires some boilerplate initializing them too.
For reference to the problem you can check this question in stackoverflow:
https://stackoverflow.com/questions/77541454/call-swift-code-from-kotlin-multiplatform

Describe the solution you'd like
I would like to be able to replace the above boilerplate by introducing an annotation that automatically generates, in a specific module, a factory that will bind my swift implementation to my kotlin interface definition. Sort of bellow setup

// kotlin-lang

interface Action {
  fun test()
}

// swift-lang

@KoinBean
public class SwiftAction : Action {
  public init(){}

  public func test() {
    print("Test Passed")
  }
  ...
}

Where "KoinBean" refers to the annotation I am proposing. Which in swift I believe the equivalent is called attributes. This is docs: https://docs.swift.org/swift-book/documentation/the-swift-programming-language/attributes/

Describe alternatives you've considered
The repetitive steps in the above problem description.
