I moved this to the Development section, as I thought it might receive better attention there. I hope that was OK.

You have not inserted any value At 0 index, That's why this error occur. Insert some value at 0 Index and run your app.I think it will be helpful to you.

@Tim: Thanks buddy. My bad for posting in the wrong forum.

@Christopher: I redid the sqlite table and again tested the file but this time it created a different error. I am not very comfortable with sqlite and datamodels. However, I figured out that it is the connectivity issue now.

It is through fetch error. I believe there is some error with xcdatamodel file. If you suggest, i can PM the sqlite db and the file in concern. May be we can get forward with it?

TIA
