RealmService.swift: "Migration is required ..."

[neolefty]

Running into an error during app startup, in RealmService.swift, line 24. Screenshot is attached.

It didn't happen when I originally ran the app, and I haven't made any changes, but now it happens every time, even when I roll back to an earlier version. Based on the message, could it be related to serialized preferences or something? I'm new to xcode unfortunately ...

xcode says:

"fatal error: 'try!' expression unexpectedly raised an error: Error Domain=io.realm Code=0 "Migration is required for object type 'Tag' due to the following errors:

• Property 'end_position' is missing from latest object model.
• Property 'length' has been added to latest object model." UserInfo={NSLocalizedDescription=Migration is required for object type 'Tag' due to the following errors:

Deleting the app from the emulator and running it again fixed it. Thanks James!
