When presenting the UIColorPickerViewController directly in a Catalyst app selecting a color will invoke colorPickerViewControllerDidSelectColor(_ viewController: UIColorPickerViewController) However if you click the "Show Colors" button to see the expanded color selection pop over then the change or selection of colours in this window won't invoke colorPickerViewControllerDidSelectColor(_ viewController: UIColorPickerViewController) and there doesn't seem to be a way to capture the color.

I'm using a UICollectionView in a catalyst app to select photos. If I'm running it on an iPad I'm able to select multiple cells however the exact same code when running on macOS results in collectionView(_ collectionView: UICollectionView, didDeselectItemAt indexPath: IndexPath) being called. Note that shouldDeselectItemAt is not called. On the collection view allowsMultipleSelection is set to true.Has anyone else come across this or have any ideas of where to look?
