我有以下公开枚举

public enum OfferViewRow {
    case Candidates
    case Expiration
    case Description
    case Timing
    case Money
    case Payment

}

和以下mutableProperty：

private let rows = MutableProperty<[OfferViewRow]>([OfferViewRow]())

在我的init文件中,我使用一些reactiveCocoa来设置我的MutableProperty：

rows <~ application.producer
    .map { response in
        if response?.application.status == .Applied {
            return [.Candidates,.Description,.Timing,.Money,.Payment]
        } else {
            return [.Candidates,.Expiration,.Payment]
        }
}

但现在的问题是,当我尝试在我的行内获取我的枚举的值时,它会抛出错误.请看下面的代码.

func cellviewmodelForRowAtIndexPath(indexPath: NSIndexPath) -> viewmodel {
        guard
            let row = rows.value[indexPath.row],let response = self.application.value
            else {
                fatalError("")
        }

        switch row {
        case .Candidates:
             // Do something
        case .Expiration:
            // Do something
        case .Description:
           // Do something
        case .Timing:
           // Do something
        case .Money:
           // Do something
        case .Payment:
           // Do something
        }
    }

它抛出一个错误：Enum case’some’没有找到类型’OfferViewRow在行let row = rows.value [indexPath.row]

并且在每个switch语句中都会抛出：Enum case’Candidates’not found in type’< Error type>>

有人可以帮我弄这个吗？
