Xcode 6 only contains the iOS 8.0 SDK.

If you're running iOS 8.1 on your phone, then you'll need to upgrade to Xcode 6.1, which contains the iOS 8.1 SDK.
如果您在手机上运行 iOS 8.1，则需要升级到包含 iOS 8.1 SDK 的Xcode 6.1。

Download the latest version of Xcodefrom the App Store. I had an early version of XCode 6.1 that lacked the 8.1 SDK. Upgrading to the latest fixed the problem.
从 App Store下载最新版本的 Xcode。我有一个缺少 8.1 SDK 的早期版本的 XCode 6.1。升级到最新解决了这个问题。

Opening project in Xcode 6.1 then again in 6.0.1 seemed to fix issue, if your project is not ready to be compiled in 6.1!
如果您的项目尚未准备好在 6.1 中编译，则在 Xcode 6.1 中打开项目然后在 6.0.1 中再次打开似乎可以解决问题！

Did you check your apps' base version. If the base version is set to 8 and your device is 7, you will probably get this error.
您是否检查了应用程序的基本版本。如果基本版本设置为 8 而您的设备是 7，您可能会收到此错误。
and if your base version, from what i imagine is 8.1 and your device is not updated to 8.1 it wont work either.
如果您的基本版本是 8.1，并且您的设备没有更新到 8.1，那么它也不会工作。

Xcode 6.4 beta would not run iOS 8.3. Switched to Xcode 6.3 fixed the issue. And then when opening it back in 6.4 beta, was working fine.
Xcode 6.4 beta 无法运行 iOS 8.3。切换到 Xcode 6.3 解决了这个问题。然后在 6.4 测试版中打开它时，工作正常。

Just ran into this after absentmindedly upgrading my phone to iOS 8.3. Resolution required an upgrade to OS X Yosemite (10.10) before I could update to a version of Xcode that supports that version of iOS.
在心不在焉地将我的手机升级到 iOS 8.3 之后就遇到了这个问题。解决方案需要升级到 OS X Yosemite (10.10)，然后才能更新到支持该版本 iOS 的 Xcode 版本。

I have seen this error before in my experience. It means that the Developer Disk image in your Xcode is not compatible with the one in your iOS device that you are trying to run/develop an app with. One of the easiest way to solve this is update your Xcode installation. Another quick trick that I learned with is by copying Developer Disk image versions into Xcode.app's directory.
我以前在我的经验中见过这个错误。这意味着您的 Xcode 中的 Developer Disk 映像与您尝试运行/开发应用程序的 iOS 设备中的映像不兼容。解决此问题的最简单方法之一是更新您的 Xcode 安装。我学到的另一个快速技巧是将 Developer Disk 映像版本复制到 Xcode.app 的目录中。
I earned some copies of different versions of Developer Disk image from various Macbooks that have updated and outdated Developer Disk images. You could download some resources online, extract it and then place the whole directory on your Xcode's installation directory normally located here: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/.
我从各种 Macbook 中获得了一些不同版本的 Developer Disk 映像副本，这些 Macbook 已更新和过时的 Developer Disk 映像。您可以在线下载一些资源，将其解压缩，然后将整个目录放在 Xcode 的安装目录中，通常位于此处：/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/.
I hope this helps!
我希望这有帮助！
