when I load my application it shows a warning message that
\"Could not load the \"\" image referenced from a nib in the bundle with identifier \">
My case was a bit different. I was using an old IBDesignable
element which had some property of setting an image directly from the storyboard. Since that element was old, hidden and unused the images it had were not present in my assets folder.
Now Xcode won't be able to search this image since it is not in the project anymore. But if you search in the finder, inside your project, you'll find the XIB/Storyboard
in which it is mentioned. From there you can find it manually by opening that XIB or Storyboard as source code and search. Once found either replace them with a new image or remove the unused element.
