Swift 4 update:

Insert it into prepare(for segue: ...

if splitViewController?.displayMode == .primaryOverlay {
    let animations: () -> Void = {
        self.splitViewController?.preferredDisplayMode = .primaryHidden
    }
    let completion: (Bool) -> Void = { _ in
        self.splitViewController?.preferredDisplayMode = .automatic
    }
    UIView.animate(withDuration: 0.3, animations: animations, completion: completion)
}
