I have an iPhone app, and I'm taking a few features of the app and creating a new app.
What's the appropriate way to build two apps from a common code base?

I got this from an Xcode expert:
Xcode has two affordances to do the right thing here:
1) For files outside your project tree that your project requires, set up a source tree. Xcode > Preferences > Source Trees, define a symbolic path (e.g. EXTRA_SOURCES) with the actual path on your disk to where they're checked out. Then when you add those files to your project, add them Relative to Source Tree to that source tree.
(N.B. Quit and restart Xcode after defining the source tree in Prefs.)
2) In Xcode 3.2, define the Project Roots to include the Source Tree. Project > Edit Project Settings > General tab, "Configure Roots & SCM" button. Add the source tree to the Project Roots and set up its repository, which can be a separate repository from your main project files.
That's it. You have one file tree, from one repository, but many projects can share it, and if you perform an SCM operation on the source in one project it's reflected in others.

Keep the common code in a common repository. Then you can easily use it in as many projects as you want.

Ideally you would be able to make a dynamically linked shared library (or "framework" in Apple parlance) from the common code, but the iPhone platform does not support this. In addition to the approaches already suggested here, you can link against your own static libraries.

One more option nobody seems to have mentioned yet - you can create a new target in the original project file. I do this for "free" and "paid" versions of the same app, but it'd be useful for any two apps that share most of the same code.

I tried to do this, but got stuck. I changed the new target's plist main xib file to point to my new xib file, and made an app delegate for the new target, but I can't figure out how to get the new xib to use the new app delegate. It seems to have a generic app delegate block in it.

If I understand you correctly, this article is what you're looking for:
