A swing in theater covers multiple roles to keep the show running smoothly and make sure the audience never notices a performer is missing. They prevent injuries and maintain the illusion that the same cast performs every night.

One of the major roots of what I do as a swing in general and specifically as a universal swing, is the audience. They should not be able to look at the show happening in front of them and say, that person seems like they just joined or that they're not the person who does this every night. They should be able to look at the show and think that the cast of performers on stage that evening is the cast of performers that is doing the show every night. So it's the baseline of my responsibility that I have assigned to myself is I'm there to make sure the show happens. That's awesome. And ideally, that means no one gets injured. I don't get injured.
