I am having the same issue.
How can I get the selected value in picker view(Without scrolling) after presenting the alert controller for the first time?

Please suggest something

Very simple solution here.

1. Make a function that returns the value or the picker itself in an extension of UIAlertController
2. You can get the DatePickerViewController or PickerViewController by
   value(forKey: "contentViewController") function
3. add an action to your alertController and in the handler revoke the values from the function.
   Will make a merge request for it. 😃
   Example Code

private func selectDate(_ handler: @escaping ((TimeInterval) -> Void)) {
        var dateTimeInterval: TimeInterval = 0
        let alert = UIAlertController(style: .actionSheet)
        alert.addDatePicker(mode: .date, date: nil, minimumDate: nil, maximumDate: nil) { (date) in
            dateTimeInterval = date.timeIntervalSince1970
        }
        alert.addAction(title: "确定", style: .cancel) { (_) in
            handler(dateTimeInterval)
        }
        present(alert, animated: true, completion: nil)
    }
