I am new to Swift and didn't find a good explanation when to use a new ViewController and when to use another scene.

Example: You are programming a game with a menu, a level selection screen and the game screen (on which you play the level).

From my understanding, I would be able to program everything with only one ViewController, but multiple scenes (menu, level selection and level)

When (and why) would I use more than one ViewController for that?

Thanks!

Having a different ViewController for different screens (I assume you're talking about SpriteKit) has one main benefit: You can keep all menu screen logic in the menu's ViewController and game/level logic in another one.

I would use the same ViewController class for all levels since the code to handle the game just be used continuously, swapping out SKScenes.

Very low lvl way to put it...

Each screen of your app is a View and a corresponding ViewController that is the class of that view.

So you go to your storyboard and you place a button and a label. Then you connect those elements to your ViewController class. Now your ViewController is aware that there is a button and a label. Now on ViewController you just have to set a function that says: When I press this button, change my label.

Check this: Storyboard and ViewController

Try to right click the button and drag it to the code, it will do the connection for you.

    You completely ignored the part of his question that was about scenes. It's clear he's talking about SpriteKit, which doesn't have much to do with outlets and UIViews. – cookednick May 20 '19 at 19:56
