Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIColor 0x1e37e4878> valueForUndefinedKey:]: this class is not key value coding-compliant for the key knockout-white.'

In Uimage in Xcode 12 don't throw any exception. My code:
Image(systemName: self.Marked ? "checkmark.circle.fill" : "circle")
.renderingMode(.original)

I am getting the exact same error on iOS 14.2 (beta 1), by coincidence trying to load the exact same image:

Code Block Image("checkmark.circle.fill")
	.renderingMode(.original)

It is crashing with other multicolour SF Symbols as well. It must be a bug, and is not under the known issues in the beta release notes. Have filed under FB8725305

FWIW, I am also seeing this crash with a multi-color image: "xmark.octagon.fill"

This has been driving me a little insane. Soon as my app starts it dies with this error. Hadn't managed to figure out the cause of it, so thank you.

I'm getting the error on 14.0GM, and 14.2b1, with the App built with either Xcode 12b6 or Xcode 12.2b1 (on a DTK). Had thought it was DTK related, so this is kinda good news.

I was using a couple of multicolour SF symbol's, "text.badge.plus" and another I can't recall.

Edit:

So it is just the call to

Code Block  .renderingMode(.original)

that is causing the crash. Commenting those out the app works fine.
