Swift 3 - 比较Date对象 [英] Swift 3 - Comparing Date objects

问题描述

我正在将我的应用更新为Swift 3.0语法（我知道它仍然处于测试阶段，但我想在发布后立即做好准备）。

I'm updating my app to Swift 3.0 syntax (I know it's still in beta but I want to be prepared as soon as it released).

在上一个Xcode测试版（Beta 5）之前，我能够使用操作数<比较两个 Date 对象code>< ，> 和 == 。但在最新的测试版（Beta 6）中，这已不再适用了。以下是一些截图：

Until the previous Beta of Xcode (Beta 5) I was able to compare two Date objects using the operands <, > and ==. But in the latest beta (Beta 6) this isn't working any more. Here are some screenshots:

正如您在两个屏幕截图中看到的，这些是两个 Date 对象。但是我收到以下错误：

As you can see in both screenshots, these are two Date objects. But I get the following error:

我做错了什么？这些函数仍然在 Date 类中声明：

What am I doing wrong? The functions are still declared in the Date class:

static func>（日期，日期）

如果左手日期时间较晚，则返回true比右手Date。

Returns true if the left hand Date is later in time than the right hand Date.

这只是一个Beta bug还是我做错了什么？

Is this just a Beta bug or am I doing something wrong?

推荐答案

我在XCode 8 beta 6中尝试过这个片段，它运行正常。

I have tried this snippet in XCode 8 beta 6, and it is working fine.

let date1 = Date()
let date2 = Date().addingTimeInterval(100)

if date1 == date2
{
}
else if date1 > date2
{
}
else if date1 < date2
{
}
