Discussion
This property contains a bitmask of constants indicating which touch properties could not be reported immediately. For example, Apple Pencil records the force of a touch, but must transmit that information over the air to the underlying iPad. The delay incurred by transmitting the data may cause the information to be received after the touch has been reported to your app.
Values in this property are not guaranteed to be updated later. For a list of properties whose values are expected to be updated, see estimated.
