SWIFT Error in generated source when using only 200 and 204 return status

When using a response containing only 200 and 204 response status

swag:

    "/api/something/{somethingID}/documents/{attachmentID}/ownership": {
         ...
        "responses": {
          "200": {
            "description": "OK",
            "schema": {
              "$ref": "#/definitions/EntityOwnership"
            }
          },
          "204": {
            "description": "No ownership currently taken for this entity."
          }
}

Swift Result is

           public var success: EntityOwnership? {
                switch self {
                case .status200(let response): return response
                }
            }

which fails compiling in swift as enum is not exhaustive, should be :

           switch self {
           case .status200(let response): return response
           default: return nil   // OR case .status204: return nil
           }

If 204 is provided alone, it works, if 204 is with another code != 200 also works

Start from the generated Swift Result enum shown in the report and trace how response statuses are represented when both 200 and 204 are present. Reproduce the case with only those statuses, then verify that the generated switch handles every enum case and that the Swift source compiles.
