Can't run Instruments from Xcode

Question

I recently upgraded to Snow Leopard and since then I am having difficulty running Instrument to instrument my app from Xcode. The Record button would be grayed out, and nothing

Answer 1

Make sure all of your instruments support recording modes. When I upgraded from Xcode6 to Xcode7, one of my instruments was marked as "This instrument's supported recording modes are none". When I deleted this specific instrument, the recording button becomed enabled.

Answer 2

I set the Executable field to my target name and the menu enabled again.

Answer 3

Note that if you have multiple targets, it is very likely that you need indeed to tell Xcode which one you want to profile. Use the edit targets scheme above
