In an `IPhone` app I am making, I have an `initialViewController`

(1) with a button. Once the button is clicked, it segues to another View Controller

(2), which at that point loads data from a `CoreData` File and displays it to the user.

My issue is that there is a small delay between the loading of (2) and the actual Display of the data. That is of course because the data takes a little moment to be loaded. I am doing it `asynchronously`, and my goal is to never show a spinning wheel or a loading screen (more user friendly).

What I want to do is to "`preload`" the data at (1), not at (2), that way data should have already been loaded by the time (2) loads and should be displayed immediately. **I know how to load the data at (1), but I have no idea how to easily pass it along to (2)**. I can't do it with a segue because my app is actually a bit more complicated than the description above and it's a hassle to do it via segue.

I have heard it is possible to use the "`AppDelegate`" but as I am new to programming I have no idea how to use it effectively. The online classes I've been following do not give very clear insight on how to use it, so I'm a bit lost.
