Description

I'm trying to handle network errors, i.e. any random error that will be solved by just trying again later, to redirect the user to the proper support page.

In Swift there are a good number of error codes dedicated to those:

    case kCFURLErrorUnknown                 = -998
    case kCFURLErrorCancelled               = -999
    case kCFURLErrorTimedOut                = -1001
    case kCFURLErrorCannotFindHost          = -1003
    case kCFURLErrorCannotConnectToHost     = -1004
    case kCFURLErrorNetworkConnectionLost   = -1005
    case kCFURLErrorDNSLookupFailed         = -1006
    case kCFURLErrorNotConnectedToInternet  = -1009
    case kCFURLErrorInternationalRoamingOff = -1018
    case kCFURLErrorDataNotAllowed          = -1020
    case kCFURLErrorSecureConnectionFailed  = -1200

But errors thrown from Realm do not match those codes. After trying to sign in a user for instance, I get an error like this:

(error as NSError).code // = -1
(error as NSError).domain // = io.realm.app
(error as NSError).userInfo // = ["NSLocalizedDescription": The request timed out., "HTTP Status Code": 0]

Another non-Realm process running at the same time returned the following error:
[-1001] Error Domain=NSURLErrorDomain Code=-1001 "The request timed out."

The errors thrown from Realm should have matching error codes, otherwise we can't properly handle them.
