We're buddies when it comes to location, as we're in Portugal in a VERY rocky soil condition.
Swales could increase erosion in the circumstances you mentioned, but looking at the photos and how much vegetation cover you have, I don't think it is a problem.
Also consider how close the bedrock is. If the goal is to promote in filtration, the swales might only retain the water on the surface.
Have you though about other practices, such as walls: Stone Terracing
What cover crops are you using? We're planning on using clovers, but open for other ideas.
Kindly,
Marcelo
