Could not find Developer Disk Image iOS 9.1 & Xcode Version 7.0.1 (7A1001)
提问by Felix Doe
When I try to run my app on my phone I get an error that reads "Could not find Developer Disk Image". At the top of Xcode it says my phone name with (Unavailable) after it.
当我尝试在我的手机上运行我的应用程序时，我收到一条错误消息，内容为“找不到开发者磁盘映像”。在 Xcode 的顶部，它说我的手机名称，后面带有 (Unavailable)。

As explained on this Apple forum, you need to update to Xcode 7.1 once you have updated your phone to iOS 9.1.
正如在此Apple 论坛上所述，将手机更新到 iOS 9.1 后，您需要更新到 Xcode 7.1。
UPDATE FOR iOS 9.2
iOS 9.2 更新
With the most recent update to iOS 9.2, the same problem will occur with Xcode at 7.1; you need to update to Xcode 7.2
最近更新到 iOS 9.2，Xcode 7.1 也会出现同样的问题；你需要更新到 Xcode 7.2
It seems that Apple is forcing developers to stay up-to-date with both Xcode and iOS. If you see "Could not find Developer Disk Image" in your Xcode, then your best bet to solve it is to update both your Xcode AND iOS to the most recent version.
似乎 Apple 正在迫使开发人员与 Xcode 和 iOS 保持同步。如果您在 Xcode 中看到“找不到开发者磁盘映像”，那么解决它的最佳方法是将 Xcode 和 iOS 都更新到最新版本。
UPDATE FOR iOS 9.3
iOS 9.3 更新
It seems that Apple has thrown another monkeywrench into updating your Xcode. Now, not only does your Xcode have to be updated, but your OSX needs to be on El Capitan. In fact, the store will not even suggest the update to Xcode 7.3 until you change the OSX.
Apple 似乎在更新您的 Xcode 方面又费了一番周折。现在，不仅您的 Xcode 需要更新，您的 OSX 也需要安装在 El Capitan 上。事实上，在您更改 OSX 之前，商店甚至不会建议更新到 Xcode 7.3。

for iOS 9.2 and XCode 7.2
适用于 iOS 9.2 和 XCode 7.2
I believe this is an app store bug. Because the app store says my Xcode is update to date (7.2) but then when I go to "About" in Xcode menu it still says I'm on 7.1. I manually download Xcode 7.2 outside of Appstore and it worked
我相信这是一个应用商店错误。因为应用商店说我的 Xcode 是最新的（7.2），但是当我在 Xcode 菜单中转到“关于”时，它仍然说我在 7.1 上。我在 Appstore 之外手动下载 Xcode 7.2 并且它工作正常
