Could not load the "" image referenced from a nib in the bundle with identifier

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 "

I searched and confirmed all my images. But it still shows that warning.

1. Select your image(s) in Project Navigator.
2. Open the File Inspector.
3. Make sure you have the target selected.

I had the same issue when I Refactor to Storyboard. Apparently the Asset catalog does not transfer the image reference. To fix, see below:

You would notice that your ImageViews is empty from reference.

1 - Click on the ImageView

2 Go to the Utilities bar where you would see you asset image is unknown

3 - Change it back to you image asset

This should fix your error. Hope this helps!
