If attempting to download via the App Store leaves you with a little grey spinner and nothing actually happening, then you can go to :
如果尝试通过 App Store 下载让您看到一个灰色的微调，而实际上什么也没发生，那么您可以转到：
https://developer.apple.com/download/more/
https://developer.apple.com/download/more/
log in with your Apple Developer ID, and the latest Xcode should be available as a .zip download.
使用您的 Apple Developer ID 登录，最新的 Xcode 应该以 .zip 下载的形式提供。

In my case (Xcode 6.1, iOS 8.2) I did not see the update in AppStore. I found Xcode 6.2 for download and pressed "Install". Then, it installed and asked for the update (more than 2 Gb). Xcode 6.2 works correctly with iOS 8.2 and iOS 8.1.2
在我的情况下（Xcode 6.1，iOS 8.2）我没有在 AppStore 中看到更新。我找到了 Xcode 6.2 供下载并按下“安装”。然后，它安装并要求更新（超过 2 Gb）。Xcode 6.2 在 iOS 8.2 和 iOS 8.1.2 上正常工作
Hopefully this tip will help somebody else...

If you want the latest Beta, it will not be in the AppStore. Instead you have to login to https://developer.apple.comand download from there.
如果您想要最新的 Beta，它不会在 AppStore 中。相反，您必须登录https://developer.apple.com并从那里下载。

I ran into this bugger too.
我也遇到了这个混蛋。
I was running an older version of Xcode (not compatible with ios 9.2) so I needed to update.
我运行的是旧版本的 Xcode（与 ios 9.2 不兼容），所以我需要更新。
I spent hours on this and was constantly getting spinning wheel of death in the app store. Nothing worked. I tried CLI softwareupdate, updating OSX, everything.
我在这上面花了几个小时，并且不断地在应用程序商店中获得死亡之轮。没有任何效果。我尝试了 CLI 软件更新，更新 OSX，一切。
I ultimately had to download AppZapper, then nuked XCode.
我最终不得不下载 AppZapper，然后用 nuked XCode。
I went into the app store to download and it still didn't work. Then I rebooted.
我去应用商店下载了，还是不行。然后我重新启动。
And from here I could finally upgrade to a fresh version of xcode.
从这里我终于可以升级到新版本的 xcode。
WARNING: AppZapper can delete all your data around Xcode as well, so be prepared to start from scratch on your profiles, keys, etc. Also per the other notes here, of course be ready for a 3-5 hour long downloading expedition...
警告：AppZapper 也可以删除您在 Xcode 周围的所有数据，因此请准备好从头开始处理您的配置文件、密钥等。此外，根据此处的其他说明，当然要准备好进行 3-5 小时的下载探险。 .

You DO NOT need to upgrade Xcode.
您不需要升级 Xcode。
Just open the file /usr/local/Homebrew/Library/Homebrew/extend/os/mac/diagnostic.rb,
直接打开文件/usr/local/Homebrew/Library/Homebrew/extend/os/mac/diagnostic.rb，
then remove this line check_xcode_minimum_versionin the following function.
然后check_xcode_minimum_version在以下函数中删除此行。
def fatal_build_from_source_checks
%w[
check_xcode_license_approved
check_xcode_minimum_version //<-- this one
check_clt_minimum_version
check_if_xcode_needs_clt_installed
].freeze
end
Then brew installshould works fine.
然后brew install应该工作正常。
