iPhone becomes ineligible device in Xcode 7 beta2 after upgraded to iOS 8.4
提问by Lixu
So I'm doing test on my iPhone 6 and everything works just fine with iOS 8.3. After upgrading to 8.4 my device became unavailable. Does anyone know why??

Just found out the solution:
刚刚找到解决方案：
Download Xcode 6.4
Go to its content directory: /Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Copy folder "8.4 (12H141)" which contains the device support to the same path of Xcode 7 beta and it works fine.
下载 Xcode 6.4
转到其内容目录：/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
将包含设备支持的文件夹“8.4 (12H141)”复制到 Xcode 7 beta 的相同路径，它工作正常。

you also need to change the deployment target to 8.4, as by default the version is 9 in Xcode 7 beta
您还需要将部署目标更改为 8.4，因为默认情况下，Xcode 7 beta 中的版本为 9
