I’m completely new to Unity. However I’m currently working on a obj-c/iOS game which uses parse.com to save pretty much everything, I save the assets to the server so they can be loaded at runtime I save all the players tile data, I save all the players resource data, everything. This also enables me to do a kind of asynchronous game play as all of the data is external.
So my question what would be the best way to do that in Unity? with the aim being to publish for iOS?
