Custom demo spread

Question

I am making my first custom segue animations. I want to have a list view that when I select a row, instead of sliding from the side, expands in place from the selected row. Sort of:

Thus, the user selects the green line, which causes the new controller to start with the green line size and expand to fill the screen. So far, this part has worked fine.

class FromScheduleFocusSegue: UIStoryboardSegue {
    override func perform() {
        let fromView = self.source.view!
        let toView = self.destination.view!
        let window = UIApplication.shared.keyWindow!
        let schedulesList = self.destination as! SchedulesListController
        let cell = schedulesList.tableView.cellForRow(at: schedulesList.tableView.indexPathForSelectedRow!)!
        var stripe = cell.bounds
        stripe.size.height = 60
        let targetFrame = cell.convert(stripe, to: window).insetBy(dx: 0, dy: 0)
        schedulesList.tableView.selectRow(at: nil, animated: false, scrollPosition: .none)
        UIView.animateWithDuration(4000.milliseconds, delay: 0.seconds, options: .curveEaseInOut, animations: {
            fromView.frame = targetFrame
        }) { (finished) in
            self.source.dismiss(animated: false, completion: nil)
        }
    }
}
