Highlighted property is only for display within Interface Builder
You have a UIImageView with Highlighted set to true in Xcode. Xcode tells you that the value is for WYSIWYG but won't work at runtime.
After looking at warning message details I got to know, but still there was no way, I could find particular Image is having highlighted="YES"
Perfect Trick suggested by @Keller in Accepted answer's comment.
Just right click your Storyboard --> Open As --> Source Code.
search for
highlighted="YES
Just set YES to NO.
or event if you look carefully code around searched string, you can get in which ViewController's Scene particular ImageView.

Right click on your Storyboard -> Open as -> Source Code.Search for highlighted = "YES".Check the name of the image.Find the image on the Storyboard.Click the image, go to Show the Attributes inspector.Uncheck the Highlighted option
