I need to refactor an app, written long time ago. As a begginer, I'm struggling a little bit with a bunch of new question.
It was written in objective C.
It has included some frameworks (security, coredata, quartzcore, mapkit...) and application uses tapku library. That's what I know so far.
There is an XmlRpc external there. My question is: If that all is written in 2014. from some random guy, do I need to change/upgrade all of this frameworks/external etc. and find a newer version of it on the internet, or I can use it as they are?
Edit: I'm rewriting the whole project, I need to fix things that are not working, (I didn't find any still, though) and I'm just asking if I would have benefits (speed of application, user experience etc.) if I include a newer version of all of these frameworks, if that is possible.
