xcode debugger options

Question

What are the three options we see in the debug console in Xcode? Just curious to know why there are three options? What purpose each option serve?

Answer 1

Debugger output is stuff printed by the debugger itself, and target output is what is printed by your application (printf, NSLog, etc).

Answer 2

Perhaps a read through of the Xcode User's Guide would do us all a little good tonight:

The Console Pane

The console pane displays program output and lets you enter commands to the debugger tool. You specify the type of output the console displays with the pop-up menu in the top-left corner of the console pane:

All Output displays target and debugger output.

Debugger Output displays debugger output only.

Target Output displays target output only.
