类型...模棱两可，无需更多上下文 [英] Type ... ambiguous without more context

问题描述

将iOS应用迁移到Swift 3.0的过程.这是我面临的一个问题.

On the process of migrating an iOS app to Swift 3.0. Here is one issue I am facing.

首先输入相关代码:

let calendar = NSCalendar.current,
calendCompo = calendar.components([.Year, .Month, .Day, .Hour, .Minute, .Second], fromDate: NSDate())

第二个问题:

对于第二行，我收到此错误消息:

I am getting this error message, for the second line:

Type of expression is ambiguous without more context

我也尝试了以下代码:

let calendar = NSCalendar.current,
calendCompo = calendar.components([.year, .month, .day, .hour, .minute, .second], fromDate: NSDate())

但这没什么区别.

我需要如何修改代码才能使其正常工作? 感谢您提供任何相关提示.

How do I need to modify the code to make it work? Thanks for any relevant tip.
