prepareForSegue VS. performSegueWithIdentifier

I am somewhat confused when it comes to when to use what?

I can use performSegueWithIdentifier to switch to another ViewController, and the prepareForSegue handles stuff you want to do BEFORE you actually switches to a ViewController?

Correct, prepareForSegue prepares data to passed between view controllers where as performSegue actually allows the switch to happen.

I'd like to know why use prepareforsegue if you can just store the data in a Dictionary?

It seems easier if you just initialize the dictionary in the first view controller and add/edit/remove from it in the subsequent view controller.

I'd like to know if this is a bad practice or will either work just fine?

I'm currently using a dictionary to pass data forward to view controllers.

Thanks in advance for your response.
