# geoJSONDidComplete(result, geoJSON) Completes the GeoJSON import. ``` geoJSONDidComplete?( result: ItemCollection, geoJSON: D, ): void; ``` ## Parameters `result` The mapped item collection. `geoJSON` The original parsed GeoJSON object. ## Discussion After MapKit JS loads the GeoJSON data and converts it to MapKit objects, the framework calls [`geoJSONDidComplete(result, geoJSON)`](/documentation/MapKitJS/GeoJSONDelegate/geoJSONDidComplete) with the resulting [`ItemCollection`](/documentation/MapKitJS/ItemCollection), which reflects any provided customizations. This is the same value that returns directly from [`importGeoJSON(data, callback)`](/documentation/MapKitJS/mapkit/importGeoJSON) in the synchronous case. --- Copyright © 2026 Apple Inc.
