Error: CUICatalog: Invalid asset name supplied: (null), or invalid scale factor : 2.000000

Maybe you can use this to confirm the "imageName" is not a "nil";Then you will leave away this warning.

if (imageName) {
self.imageView.image = [UIImage imageNamed:imageName];
}

This one appears when someone is trying to put `nil` in `[UIImage imageNamed:]`

Add symbolic breakpoint for `[UIImage imageNamed:]`![Symbolic breakpoint example][1]

Add `$arg3 == nil` condition on Simulator, `$r0 == nil` condition on 32-bit iPhone, or `$x2 == nil` on 64-bit iPhone.

Run your application and see where debugger will stop.

P.S. Keep in mind this also happens if image name is empty string. You can check this by adding `[(NSString*)$x2 length] == 0` to the condition.

This happened to me after a storyboard was split into several (the actual change happened when I was on holidays, so I don't know exactly how it was done).

After inspecting the XML of the storyboards, I found that an image reference which previously had pointed to "bottomBar" in the assets catalogue instead pointed to `imageView:fFo-1g-jzs:image`.

At the end of the XML file under the `<resources>` tag was tag named `<image name="imageView:fFo-1g-jzs:image">` containing a big `mutableData` blob.

After resetting the image reference in the storyboard and removing the blob, the error went away.

In my case I have implemented cell with UILabel, UIImageView and UITextFied, sometimes I don't want to display image, in that case I'm sending empty string `""` to the imageView. Now the same error/warning is getting.

Error: `[framework] CUICatalog: Invalid asset name supplied: ''
`

Solution is we have to pass `nil` instead of `""` empty string.

Code:

if imgName.count > 0 {
selectedIconView.image = UIImage(named: imgName)
} else {
selectedIconView.image = nil
//You can also use
//selectedIconView.isHidden = true
}
