What do I need to create my news app so I'm able to update it without reoploading the app : I'm interesting in trying to build an news app as a learning project. My plan is that on my app you can access a few different categories and in those categories there are some text that I myself has written. (Not a url from a news website or something like that)

But if I made my app and wrote my articles directly in xcode, I would not be able to update it as soon as I (theoretically) oploaded it to an app store.  

Can anybody point me in the direction, so that I can research about the logic behind making such an app.
