[resolved] Hi all,
While applying a clean architecture, it is cumbersome to write code to transform the model from Data to Domain. Can I use KSP to automatically generate a mapper code?

Think only if the data model and the domain model have the same properties.

Yes it is possible (also I presume you could use simply a typealias or reuse the data class if it's 1-1)

Thank you so much It was very helpful.
If that's the case,
1. Is it possible to have a list of properties?
2. Is it possible for a domain model to receive some properties of the data model?

1. You can have the name and the type of the signature of each members (property or method) with info like visibility or backing field. Should be enough to generate a mapper.
2. Not sure to understand the question.

This is the case

Data 
```UserDTO(val id: Int, val name: String)```
Domain
```User(val id) ```

Alright, so you want to generate a UserDTO.toDomain() function that uses the primary constructor of User. That's totally doable, given there is a perfect matching of names between the 2 classes. If it's not the processor could generate an error to show the matching issue, or simply avoid generating the mapping function.
