Notes on building MapConductor, and what we learn about maps along the way.

We participated in the 14th Technical Book Expo

As the MapConductor circle, we participated in the technical self-published book event "Technical Book Expo" and sold our SwiftUI book "Learning Map App Development with a Weather Forecast App — MapConductor Introduction —". In this book, beyond introducing MapConductor itself, we present map app development knowledge that does not depend on a specific map SDK, such as how to fetch and display weather forecast data and code design. At the event, we spoke directly with visitors and received a variety of feedback about the book and MapConductor. We plan to participate in the next "Technical Book Fest 21" to be held on November 23, 2026, where we intend to introduce new developments including Android and React versions.
