The screensavers I've found in the App Store are not .saver files. They are backgrounds where you can hide your desktop icons or standalone applications that become fullscreen when you open them. Distributing a .saver via the App Store doesn't seem possible at the moment.

I bundled my .saver file with an app that opens the file on init, then exits. This asks the user to install the screensaver using Apple’s prompt. Apple rejected my app due to Guideline 2.4.5(ii). It states that apps “cannot install code or resources in shared locations”. Specifically, they said my app attempts to install a screensaver and to remove that functionality. It’s odd, because there are screensavers currently in the App Store. I don’t know how they distribute without installing the .saver
