Ok, i found right solution here.

1) Set the display mode to NCWidgetDisplayMode.expanded first in viewDidLoad:

override func viewDidLoad() {

    self.extensionContext?.widgetLargestAvailableDisplayMode = NCWidgetDisplayMode.expanded
}

2) Implement new protocol method:

func widgetActiveDisplayModeDidChange(_ activeDisplayMode: NCWidgetDisplayMode, withMaximumSize maxSize: CGSize) {
    if (activeDisplayMode == NCWidgetDisplayMode.compact) {
        self.preferredContentSize = maxSize
    }
    else {
        //expanded
        self.preferredContentSize = CGSize(width: maxSize.width, height: 200)
    }
}

And it will work as official apps.
