I've been following the "Build your second iOS app" tutorial step for step and I have run into this error after the tutorial promised that all the errors would go away, but the error didn't show up until after the other errors were all corrected and I tried to compile it.
The error:
The document "MainStoryboard_iPhone.storyboard" could not be opened. Failed to unarchive element named "UITableViewController".
Here is a link to the tutorial.
Here is my storyboard in XML format

I am completely new to objective c and Xcode so I'm not sure what I'm doing wrong or even really where to begin with an error like that. If anyone knows how to fix this error, or a better (online) resource for learning both objective c and iOS development at the same time, I would really appreciate either one.
Here is my project if anyone wants to take a look at it for me.

I was able to find out what I did wrong on the tutorial. Rather than drag the TableViewController and delete the DetailViewController I dragged a table onto the controller on top of the detail view. I'm not sure how I missed that, I must have been really tired yesterday.
Also, anyone who is stuck on the apple iPhone development tutorial, I highly recommend the "Stanford iPhone development" series on iTunes. I'm going through it right now and it is amazing. It explains things that the apple tutorial never did (like when to use strong vs weak in properties, atomic vs nonatomic also in properties). I know I'm starting to understand objective c because I actually know what to google when I get stuck.
