Hi Bob Blonchek, 
Thank you for contacting Syncfusion support. 
Based on the provided information, we have checked the mentioned issue “DataForm throws null exception while using Switch editor in DataForm” Xamarin.Forms (Android) and we unable to replicate the issue from our end. We have tested switch editor inside DataForm, custom switch editor with SfSwitch and custom DataFormItems. We have prepared sample for the same, 
Sample link: DataFormSwitch 
We have tested with Syncfusion update version and Xamarin.Forms version
Please check the sample and let us know if you still facing the same issue? If not, please modify the sample based on your scenario and revert us back with more details. It will be helpful for us to check on it and provide you the solution at the earliest. 
Note: DataForm doesn’t support DataFormSwitchEditor inside FloatingLabel layout. If you are using FloatingLabel layout kindly refer our UG documentation to know about supported and unsupported editors,
