This sample demonstrates how to add or delete related features on an origin feature. Click on a park in the map view. A list of species as related features will be shown. Click on the Add button on the top right to add a new specie to the park. To delete a specie select it and press the Delete key on the keyboard.
How it works
To add a related feature, the sample uses createFeature(attributes:geometry:) method on the related feature table AGSServiceFeatureTable. The new feature is then related to the origin feature using relate(to:) method on AGSFeature. Then its added to the related feature table using add(_:completion:) method. Similarly, to delete a related feature, the sample uses delete(_:completion:) method on the related feature table AGSServiceFeatureTable. The changes are applied to the service by calling applyEdits(completion:) on the feature table when tapped on the Done button.
