aria-label and aria-labelledby are exclusive. So they can be enforced for components in typescript:

type ToggleSwitchProps = {
  name: string;
  checked: boolean;
  handleToggle: () => void;
  size?: "sm" | "lg" | "base";
  classNames?: string;
} & ({ ariaLabel: string; ariaLabelledBy: never } | { ariaLabel: never; ariaLabelledBy: string });
