Totally agree that the model should have no dependencies on UIKit.

In fact, I’d take it a step further and say that 9 times out of 10 the ViewModel should have no dependencies on UIKit, and that rare case is when the ViewModel needs to return a custom UIColor or a specific UIImage.

When I discuss ViewModel’s with my team I like to tell them that the ViewModel should be as agnostic to the view presentation as possible. It should be entirely possible to switch out a UITableViewController for a UICollectionViewController with no changes whatsoever needed to the ViewModel.
