Reflection from structure type in Swift

Recently I'm developing API parts using GraphQL.

When I call API, I need to generate a query from structure like this.

// from this model
struct ModelA {
   let id: String
   let title: String
....
}

// to this query
query {
  id
  title
}

If I have an instance of ModelA, I can reflect properties from instance using Mirror.

But I don't want to make the instance in this case and I don't want to make the properties to variables because I need to use this model for response.

Additionally class_copyPropertyList is a good solution if the model is NSObject class. However in this case this is a structure in swift.

Is this possible? I appreciate your help in advance.
