` I'm trying to code something so the program waits for the screen to be touched. after the screen is touched, I want to change text using a SKLabelNode.
Here's an example of what I'm trying to do:
1. Wait for touch
2. Change text
3. Wait for touch
4. Change text
I want this to repeat several times before going to a different segment. I'll also need to use touches in other parts of the program.
