"You can fill the entire screen with a button and then add things inside that button.":
This would not help. I would neither know if a particular Sprite was touched, or where the user has touched the screen (Or is there a way to get the exact location where the user has touched the button?).
And since I am using SpriteKit, I can't "add things inside the button" because these things would have to be SKSprites (or the whole SKScene).
"You can add multiple buttons to the screen.":
But in order to check if a Sprite was touched, I'd have to know the exact position of the touch.
(Like touchesBegan and then getting the location of the touch as it works for IOS Apps. But sadly there is no touchesBegan for watchOS-Apps) 🤔
=> I need to know either if the user has touched a SKSprite or exactly where the user has touched the screen!
