I wanted to do some performance analysis using Xcode 7 and Instruments Version 7.0 (7A192o). Xcode copies the app to my iPad, then I start up a Time Profiler instrument, and my attached device (running an iOS 9 beta) is disabled in the popup.
I can Run on the device, just not profile.
I have profiled in the past, though probably not with this Xcode beta. Is there something I need to do in the scheme? Is it just a bug?
Attn Apple: I have spent hours on the various restarts needed to run a necessary test. Unfortunately, I'm still at a dead end with this problem. This time could have been spent enhancing my app for my (actually, our) users. If I was working hourly, I'd feel awful charging clients for this.
I've seen this multiple times. I have a Macbook Air mid 2012. Does it also happen on faster computers?
I encountered the same issue in Xcode 7.2 Your solution helped although my feedback was different, my device was still available in Xcode for instance. Thanks.

In case it's helpful, I just experienced this issue on 10.11.3, Macbook Retina and a 128GB 6S Plus. Rebooting Mac didn't help, but after restarting phone, order was restored.
That one help me too, but still can't figure out what went wrong.
I'm getting this issue with Xcode 7.3 beta 4 (7D152p) trying to profile on iPhone 6 with iOS 9.3 beta 4. I can debug fine on the device, but when I try to Profile (leaks, in this case) I get "unable to find a service to record with" on the right side of the time tracks and when I select the "Choose target..." option alongside my device name it brings up a dialog to choose the process, but no processes appear.
I haven't yet tried restarting the device or any of the suggestions above. The problem is repeatable, so what logs etc would you like me to collect before I try and fix the problem?
I have just filed a radar having reproduced this issue just now (it's always reproducible).

Yes, restarting the device fixed the issue.
It works.😮
