All errors that are thrown by the Ditto SDK are wrapped as a
DittoError. It wraps multiple different types of error that each have an associated reason.
You can access more specific information about an error by switching over the error's
reason value. If you want a human-readable version of the error then call
localizedMessage on the error's reason.
activationError: An error occurred relating to activating the Ditto instance.
storeError: An error occurred relating to the store.
transportError: An error occurred relating to the network transports.
