When incrementing a property of an object by an amount x, for example an integer, from multiple devices, this is typically done with a special type of update that ensures the final value of the property is correct even if incremented on multiple devices asynchronously.
The .NET SDK appears to have this functionality via RealmInteger. The earlier MongoDB (pre-Realm) supported this via $inc.
How can I do this via the Swift SDK using Realm w/ sync?
