Yes.  See any of the results when you google the above question.  The
thing that Apple tries to prevent is for you to compile an app, then
*distribute it yourself (cutting out Apple) to the world in binary
form*, without going through the Apple app store.  But you compile
anything you want yourself (on a mac with xcode), then you can install
it on your own devices.
