Workshops - Custom UIViewController Transitions in iOS 7

I'm having the same problem that Amit had at the end of the video and I would like to finish the project without the simulator crashing every time. I tried to download the zip file to see if I could figure it out myself but I'm getting an access denied error when trying to do that on the website.

Here is the error from http://teamtreehouse.com/library/treehouse-workshops/custom-uiviewcontroller-transitions-in-ios-7-2

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Message>Access Denied</Message>

and here is the error I'm getting from xcode

Sorry about that you should be able to download the project files now.

Thanks Amit!

My sanity has been saved... for some reason I was missing this snippet in my else statement in the Dynamic Animator implementation... Thanks again Amit!

UIGravityBehavior *gravityBehaviour = [[UIGravityBehavior alloc] initWithItems:@[fromViewController.view]];
        gravityBehaviour.gravityDirection = CGVectorMake(0, 10);
        [self.animator addBehavior:gravityBehaviour];

        UIDynamicItemBehavior *itemBehaviour = [[UIDynamicItemBehavior alloc] initWithItems:@[fromViewController.view]];
        [itemBehaviour addAngularVelocity:-M_PI_2 forItem:fromViewController.view];
        [self.animator addBehavior:itemBehaviour];
