Run Instruments and Debug Console simultaneously

How can 开发者_C百科I make an app "Run with performance tool" and at the same time Run the Debug Console in XCode?

You can use "Console" application on the mac itself. Any NSLog and several types of warnings/errors will show up in the "Console messages" section.

This is of course just logging, interactive debugging is not an option.

Just show the debug console  + MAJ + r or simply go to XCode preferences, Debuging section and set Show console on start.
