Rxswift绑定到枚举

我有以下视图模型,我想将其绑定到uitextfield和uisegmentedcontrol。我能够成功绑定到uitextfield,但uisegmentedcontrol绑定不起作用,因为我推荐的数据类型是枚举。

enum Recommend: Int  {
    case yes = 0
    case no = 1
}

struct FeedbackViewModel {

    var name = Variable<String>("")
    var recommend = Variable<Recommend>(.yes) 

}

在视图控制器中,我有以下绑定:

private func configurebindings()。{

self.nameTextField.rx.text
        .orEmpty
        .bind(to: self.feedbackViewModel.name)
        .disposed(by: disposeBag)

self.recommendSegmentedControl.rx.value
    .bind(to: self.feedbackViewModel.recommend.value.rawValue)
    .disposed(by: disposeBag)

}

对于推荐的SegmentedControl绑定,我得到以下错误:

Cannot invoke 'bind' with an argument list of type '(to: Int)'
