I have a question about app updates. Usually in Android apps, when we wanted to add more levels, we implemented in app update, whch basically connects to our server and if there are new levels, downloads level definitions (json) and stores them inside app
Now I've been playing around with ios device with one game app, and appstore notified me of app update, which added new levels. Update didn't override existing installed app, only added new levels, all game progress is still saved, etc.
Question, how is this done? Is it similar update, that only adds new level definition files or it is new compiled app which is installed on existing one. For example, if I'm saving game progress in Gideros Document folder, when installing new version, will it be overwritten?
