Xcode error: unable to copy symbols from this device

I was working on creating an app for Watch OS 2. Wanted to test it out on the watch so plugged in my iphone I used in the past. It gave it as an illegibale device. So I went to devices and saw the following error:


Unable to copy symbols from this device

Xcode was unable to read the required data from the device.


The iphone was updated to IOS 9 as needed to get the watch OS working. Anything I'm missing?

But it does not seem to work for me. Can check it out (especially end of thread).
