Is there a new version of the Landmarks app (or a similar publicly available Xcode sample app) to use from the most recent WWDC?

Yes — the most recent WWDC does show a newer treatment of the Landmarks app.

In WWDC25’s Build a SwiftUI app with the new design, Apple explicitly says they are applying the new design system to the Landmarks sample project and updating it with the new APIs. So if you’re looking for a recent example of Landmarks adapted to the latest design language, that’s the one to use.

If you’re after a publicly available sample app, I don’t have evidence in the provided context of a brand-new standalone Landmarks download from WWDC25, but Apple does clearly use Landmarks as the current sample project in that session.

A related newer sample project is Destination Video, which Apple used in Platforms State of the Union to demonstrate the new design in a sample app.

So the short answer is:

• Yes, Landmarks is being updated in WWDC25 in the SwiftUI design session.
• I don’t know of a separate new public Landmarks download beyond that from the context provided.
• Destination Video is another recent public sample Apple used to show the new design.

If you want, I can point you to the most relevant session for Landmarks + the new design.
