This doesn't seem to be going away.
Here's the problem - I choose Product > Profile in XCode. Instruments opens, asks what I'd like to track, I choose Time Profiler, and it opens, but won't let me start the task, stating the error
Target failed to run: Remote exception encountered: 'Failed to get task for pid 1461'".
The 1461 changes to something different every time.
In Xcode, I have my Profile scheme's build configuration set to "Debug". In the target's build settings I have Code Signing Identity set to iPhone Developer for everything right now. In the project's build settings I have the same.
How can I get rid of this error, so I can test my app?
EDIT: Turns out I had to delete the app from my phone, and I did Product > Clean along with restarting xcode too.
