iOS 14 UISplitViewController remove "hide/show" button in landscape on iPad?

In iOS 14, the new split view controller handles the bar button items for you. That's cool! So in portrait we see this:

enter image description here

We're in portrait, so that button at the top left summons the "overlay" version of the Primary column.

And in landscape we see this:

enter image description here

We're in landscape, so that button at the top left hides or shows the "side by side" version of the Primary column.

Now I want to know how to control the presence of these buttons individually. I see that I can set presentsWithGesture to false to hide both buttons, but that's not what I want. My question is: how can I hide the second button (landscape) but not the first button (portrait)?

In SwiftUI, this solution works – tested on iOS 16!

extension UISplitViewController {
    open override func viewDidLoad() {
        preferredDisplayMode = UISplitViewController.DisplayMode.oneBesideSecondary
        
        // remove sidebar button, make sidebar always appear !
       presentsWithGesture = displayMode != .oneBesideSecondary
        
    }
}

Set a delegate on the split view controller and implement this delegate method:

func splitViewController(_ svc: UISplitViewController, willChangeTo displayMode: UISplitViewController.DisplayMode) {
    svc.presentsWithGesture = displayMode != .oneBesideSecondary
}
