I am repeatedly seeing this error when attempting to call reloadItems(_:) on a NSDiffableDataSourceSnapshot instance.
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: indexPath || ignoreInvalidItems'
Code Block Swift var dataSource: UITableViewDiffableDataSource<Section, Foo>! func incrementFoo(_ foo: Foo) { var snapshot = dataSource.snapshot() var foo = foo foo.upvoteCount += 1 snapshot.reloadItems([foo]) dataSource.apply(snapshot) }
