positionSource property

Returns the well known key "positionSource"

This key can be used to indicate the position source of an ArcGISLocation: GNSS, AppleIPS, BLE, WIFI, CELL, IP. GNSS indicates global navigation satellite system and AppleIPS is Apple’s indoor positioning technology. It is possible to have multiple position sources. In that case positionSource is a list with comma-separated values.

This key should be associated with a string value in ArcGISLocation.additionalSourceProperties.
