I’m sure you’ve noticed the innocuous little reference to CPU and Memory utiltization in Xcode 5 when running a project:
Found a little gem today when I inadvertently clicked on the memory gauge, Xcode responded with the following (which was shown in the right pane of Xcode):
Well that was a pleasant surprise. Taking another step further I chose the option to Profile in Instruments (option in upper right corner). At this point two options were presented. First, to transfer the active debug session to Instruments without stopping the current session. Second, I could kill the current session and launch a new session in Instruments.
As you would expect, you get a similar dialog when clicking the CPU gauge.
Interesting what one can find simply poking around.
