Original README follows:
The most common issue is schema mismatch due to frequent little tweaks to the schema as you develop your app.
- Be sure to check the logs in Realm UI for more information as well as the console in your app.
- Delete the app from the simulator to purge local data.
- Restart Sync in the Realm UI by clicking "Delete Synced Data" on the Sync page.
- Be sure to deploy your changes in the Realm UI.
- If your schema does not match the server, compare the class definitions from the SDKs tab in the Realm UI with those in the client code.
- When creating objects, make sure the partition value of your new object matches the partition value you opened the Realm with.
