Why does this happen and how can I fix it?
When you’re using a UICollectionViewController, the view outlet needs to be connected to a UICollectionView in your storyboard; if it’s a UIView of another class, it’ll crash.
check HatsViewController.h is inherited from UICollectionViewController but you have connected it view in your storyboard. Either it must be subclass of UIViewController or it is connected to UICollectionView in your storyboard.

I'm getting an exception:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIImageView _isResizable]: unrecognized selector sent to instance 0x7fe01fd0d470'
I just assigned an image to the imageView inside a custom cell using storyboard.
The code is clean. It doesn't have any warnings or errors.
Two reason of this error.
If you want to assign image write.
cell.image=[UIImage imagenamed:#"Name of your image "];
and another reason of this error is you can cut the link of imageView to the outlet.
Again make a new outlet and then check now imageView is working.
i think this will help u.
there may be two or more outlet references to one imageView which makes ambiguous
Please see once the name of image in swift file and StroryBoard. Compare them they must be same.
Also check the identifier of Cell.
self.blurView = UIVisualEffectView(effect: UIBlurEffect(style: .ExtraLight)) as UIVisualEffectView
self.blurView.frame = self.filterPanel.frame
self.blurView.bounds = self.filterPanel.bounds
self.blurView.addConstraints(self.filterPanel.constraints())
self.view.insertSubview(self.blurView, belowSubview: self.filterPanel)
When attempting to run the code above in viewDidLoad it returns the error below. Why is this? I am simply trying to create a blur view with the same dimensions as the filterPanel view.

When added to a view, the constraint's items must be descendants of that view (or the view itself). This will crash if the constraint needs to be resolved before the view hierarchy is assembled. Break on -[UIView _viewHierarchyUnpreparedForConstraint:] to debug.

Thanks in advance.
The constraints self.filterPanel.constraints() all presumably relate to self.filterPanel and its subviews. Setting those constraints on self.blurView doesn't magically change them to refer to self.blurView and its subviews. You're adding constraints to a view that has nothing to do with it or its subviews.
You would need to go through all of the constraints and build new constraints that are parallel in form but refer to the corresponding view within the self.blurView sub-hierarchy, which is not going to be easy. For one thing, you've just created self.blurView so it presumably has no subviews, yet.
You might try encoding the original view to an archive and then decoding that archive to produce a duplicate sub-hierarchy.
Going through the Big Nerd Ranch iOS book, and I'm on day 2 of trying to solve this and I'm going crazy - can anyone help?
I get the following error message:

I've hooked up the BNRItemCell.xib to the corresponding class. Things fail after line 57 where the breakpoint is:
=======================================================
=======================================================
I know that it's gonna be something so basic that I'll kick myself.
Any help will be appreciated thanks!
Observing the TreeView on the left of the IB you have a UIView ( second top level element! ) below the UITableViewCell. Delete it and you should be fine!
I had this same issue. It turns out I had added another view by mistake on the .xib file
I put UISearchBar under UIView as the picture below. The problem is - after finish search or click cancel, UISearchBar will shift to the top, then I get error message:

Question:
1) Is it possible to fix position of UISearchBar? and How to do that?
2) How to fix the error?
I am trying to pull a VC xib, by adding the view of controller on window's view. When I execute the program nothing appears (a black screen), and expectation was a button put on view of VC in xib.
But when I declare that this VC is my Project's main interface (Project Summary), then it throws the exception : terminate called throwing an exceptionsharedlibrary apply-load-rules all and application crashes.
Here is the code for didfinishlaunch (Appdelegate)
[self.window addSubview:rootViewController.view];
[self.window makeKeyAndVisible];
Can somebody assist on that.
Thanks

I can't see your stack trace code or the message the debugger is giving you, but there's ALWAYS 2 reasons why it would crash here:
rootViewController.view is nil or doesn't have its view outlet set in IB.
self.window is not set in code or doesn't have its outlet connected in IB.
Check all of your outlets and see if it fixes it.
