Damn. found it after 30 mins:

in DetailViewController.m file, find configureView method.

change this line:

self.detailDescriptionLabel.text = [self.detailItem valueForKey:@"timeStamp"] description];

with:

self.detailDescriptionLabel.text = self.detailItem;

because of this line. it expecting a dictionary instead of string. thats why we get this error.

You can download the project files to double check your code in the Downloads tab
