Challenge

1. Try making the Save button disabled if there is no image in the image view.

var disableSaveButton: Bool {
    processedImage == nil
}

Button("Save", action: save)
		.disabled(disableSaveButton)

1. Experiment with having more than one slider, to control each of the input keys you care about. For example, you might have one for radius and one for intensity.

• SepiaTone - intensity
• Edges - intensity
