What project type should I use to build a QuickTime component with
Xcode? I can't find any code samples on Apple's website.

Carbon dynamic library, then follow the instructions outlined in TN 2012 for Mach-O. Ignore all the legacy CFM, OS 9 stuff obviously. Also, see Electric Image Component sample (includes five components).

Hey Andreas,

Just realized, that will get you a non-bundled component. So, more accurately you should start with the new project type "Carbon Bundle" in Xcode. Remember to rename it to .component instead of .bundle

Both work. I tend to prefer the library kind instead of the bundle kind. A bundle is a whole directory structure, which is fine for an application but overkill for a simple QT component. Just create a dynamic library and give it a .component extension. Works fine, but Apple seems to prefer the bundle kind.
For a library component, external code you link needs to be compiled with -fPIC. That's the only difference I've found.

If your component has support applications and multi-language NIB files etc, a bundle would be more appropriate.
