View Controller presenting like page sheet in iPad

Question

My app presents a View Controller in iPhone like this:

But in the iPad it presents almost like a page sheet:

I'm instantiating the View Controller programatically as a Child View Controller within a SegmentedControlViewController - e.g.:

var viewController = storyboard.instantiateViewController(withIdentifier: "IngredientsViewController") as! IngredientsViewController

How can I get the iPad to present the View Controller like the iPhone?
