I\'m trying to use Instruments to look at resource usage in my Monotouch app. However, I can\'t get the app to launch through Instruments.
When I hit the record butt
I also ran into this issue with Xcode 4. What worked for me was...
From Xcode 4, run on the connected iOS device. Launch the Instruments app manually. Choose my template (in this case TIme Profiler). Choose my app from the Target menu (to the right of the Record button). Click the Record button.
The suggested Entitlements solution did not work for me (since Entitlements are evidently no longer required in Xcode 4).
The suggested signing solution did not work either. Also, it would be inconvenient to change this every time I wanted to test with Instruments.
