Update to xcode 7.3 is not working
提问by Beto Caldas
Is someone else having problems to update xcode 7.2 to 7.3?
Firstly there is no update option in App Store. I found a link at App Store xcode 7.3, this link will open your app store on the xcode page, after I press update, a loading spinner appears but after 2 hours of waiting nothing has happened 
Is there another way to update xcode?
是否有人在将 xcode 7.2 更新到 7.3 时遇到问题？首先，App Store 中没有更新选项。我在App Store xcode 7.3找到了一个链接，这个链接会在 xcode 页面上打开你的应用商店，在我按下更新后，出现一个加载微调器，但等待 2 小时后什么也没发生，还有其他更新 xcode 的方法吗？
Edit: There is no option update xcode in App Store
编辑：App Store 中没有选项更新 xcode

xcode 7.3 is not supported in OS lower than 10.11, You need to upgrade your OS to OS X 10.11 or later (El Capitan) and try to upgrade the xcode to 7.3
低于 10.11 的操作系统不支持 xcode 7.3，您需要将操作系统升级到 OS X 10.11 或更高版本 (El Capitan) 并尝试将 xcode 升级到 7.3

You can download Xcode yourself from https://developer.apple.com/downloads(an Apple Developer account required).
您可以从https://developer.apple.com/downloads（需要 Apple Developer 帐户）自行下载 Xcode 。
This is what you should see (I filtered the available downloads by typing "Xcode"):
这是你应该看到的（我通过输入“Xcode”过滤了可用的下载）：

I had the same problem while I was trying to update to Xcode 8.1with Waiting..status on AppStore under Xcode icon. What I has done to fix this is:
我在尝试更新到Xcode 8.1时遇到了同样的问题，在 Xcode 图标下的 AppStore 上有Waiting..状态。我为解决这个问题所做的是：
1) Go to https://developer.apple.com/download/
1) 前往https://developer.apple.com/download/
2) Press Lunch Application
2) 记者午餐申请
And when it opens on AppStore, it will refresh the status from Waiting..to Downloading...
当它在 AppStore 上打开时，它会将状态从Waiting..刷新到Downloading...
