I set the executable to QuickTime player, or Safari.
I compile the component.
I copy the component into my Library/Quicktime folder.
I click on the debug icon.
QuickTime player launches.
I open the movie that uses my component.
XCode stops at my breakpoints.

How can set the XCode2.2 to debug it .

First, unless you are constrained to version 2.2, I'd strongly
recommend upgrading to 2.3.

Next, you need a "runner app" ... FiendishThings will do, as will
qt_tools, both of which are available in the QuickTime sample code.
Even the ElectricImageExampleCodec has a test runner.

Then, in XCode, in the "project menu" set the custom executable to
your "runner app" and then you can trace through your component via
it.

Or, in gdb you can attach to the "runner app" which calls your component.

Or you can put printf commands (crude, I know) in your component and
they will appear in the XCode console.

So there are a number of approaches.

I'd also love to hear what other people to do debug components.
(the only Develop article on this is over 10 years old).

Best,
Jeff
