Switching From Core Data to Realm

Tim Oliver, creator of the iComics app, gave a talk featuring Realm in his project at the Perth iOS Meetup. His talk covered gave a quick background of his transition to and experiences using Realm in place of Core Data, a switch he made in just one evening.

When I was working on iComics, I’d have problems when a background thread would import a comic, tell the main thread the comic imported, then send an object with entirely empty fields. When I tested installing a new version of the app over an older version, I found that Core Data’s auto-migration was corrupting half the database and making the app very unstable. A manual Core Data migration would have required a ridiculous amount of code, and I decided to switch to Realm.
