Understanding Basic Data Persistence (Chapter 13)

Hi there, 

I was wondering if someone could help me with my understanding of data persistence. On the core data example I wrote using the book and for the sample example provided. The code does work to a point. I can write text. Close the simulator. Open it again. Make changes. That is fine. However I cant double click the home screen, hold the icon and delete it from there. Every time I do I get an error in my main thread. 

Can someone please let me know if that is expected? I would assume not, so I'm wondering why I am getting this?

Thanks for any help anyone can give me!


  • The error you see is Xcode realizing the app it is debugging is being terminated, and is expected. In order to delete the app in the simulator, the app needs to be terminated, and Xcode can not continue debugging an app that no longer exist.
