Instruments wants permission to analyze other processes Jenkins
I just experienced a similar problem, triggered by Fastlane scan command to execute tests.
Following the discussion on this issue and this Apple Support discussion I managed to solve it by enabling "Developer Mode" on my CI machine.
$ DevToolsSecurity -statusDeveloper mode is currently disabled.$ DevToolsSecurity -enableDeveloper mode is now enabled.
I've got the same problem with Xcode 7.3. I wasn't admin on my Mac (I work on a company network) so the network manager gave me the admin rights and it works... I don't know why :)
