crash with error "Cannot create an SQL store with a nil URL."

When running DemoNotes on iOS 8.3 and 8.1 simulator, it crashes with "Cannot create an SQL store with a nil URL.".
Am I missing some setting or is the app still buggy?
I am using Xcode 6.3.1

That error probably means you haven't configured app groups for the app, or the extension, or both. It's a necessary part of creating the URL where the persistent store file goes.

Thanks for the information, would be good to have that in the readme-file.
I set up the app group now and added it both for DemoNotes and the two extensions in the xcode project. Still I get the above error. Am I still missing something?

Have the same issue.. Are we missing something?

The only thing I know of that would cause a nil URL would be app groups not being configured properly. That means:

• Turning on app groups in the project settings for the app and for all extensions
• Making sure to use the correct app group name when calling containerURLForSecurityApplicationGroupIdentifier: (which I think is only in DemoSharedCode/DemoNoteManager.m).

I should update the README. I was thinking of this project as code people could use for reference, not as anything people would actually download and run as-is.
