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:

  1. Download Xcode 6.4

  2. Go to its content directory: /Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

  3. Copy folder "8.4 (12H141)" which contains the device support to the same path of Xcode 7 beta and it works fine.

you also need to change the deployment target to 8.4, as by default the version is 9 in Xcode 7 beta
