I am a university student who also writes iPhone apps. Next year, I am expected to complete a final project that lasts a full year and includes fair software development.
My initial plan was to write an object-relational wrapper around SQLite for iPhone (or rather, for mass cleaning and expanding one of them I already have) and eventually release it as an open source. Unfortunately, with the addition of Core Data in iPhone OS 3.0, which is no longer needed. (At least, as it seems to me, any opinions on this?)
However, next year I would still like to make a useful, technically interesting project related to the iPhone. So, here is my question: what do developers need? What problems do you encounter in your applications that seem to be handled by some kind of library or framework? My focus is generally more useful for applications, performance, and communication than games. And since I offer this to the university, it would be preferable that which is theoretically interesting or attractive to potential students. And, of course, it should be something that they have not added to the new version of iPhone OS.
