react-native-maps is the de-facto standard but built on Objective-C/Java with the legacy bridge.

I rewrote it from scratch in Swift and Kotlin using Nitro Modules.

Direct wrapper of the Google Maps SDKs on both platforms — no Apple Maps fallback.

Full SDK coverage: markers (including SVG), polylines, polygons, circles, heatmaps, KML layers, tile overlays, traffic, transit, 3D buildings, indoor maps, dark mode, snapshots, and Street View (beta).
