How to show UISplitViewController Master programmatically?

I try to show the master of the SVC programmatically.

The app is universal. I have a TVC on the master and another TVC on the details. The cells on the detail-TVC can be deleted by the user. After the user deleted the last cell in the detail-TVC on iPhone (compact) the master should be shown. On iPad (regular) the next existing cell on the master-TVC is selected and shown (works fine!)

I tried to perform the displayModeButtonItem's action manually but nothing happens:

extension UISplitViewController {
    func toggleMasterView() {
        let barButtonItem = self.displayModeButtonItem()
        UIApplication.sharedApplication().sendAction(barButtonItem.action, to: barButtonItem.target, from: nil, forEvent: nil)
    }
}

For testing a added a "Show" button on the navigation-bar of the detail-TVC and performed the function above.

@IBAction func do_ShowMaster(sender: BaseUIBarButtonItem) {

    self.navigationController!.splitViewController?.toggleMasterView()

}

    self.splitViewController?.preferredDisplayMode = UISplitViewControllerDisplayMode.allVisible
