How to dynamically update swiper properties after it has been created

[ajssd]

I could not find anything in the documentation about how to modify the properties of an existing swiper instance after it has been instantiated. Is it possible?

For instance, let's say I start with this:

const swiper = new Swiper('.swiper', {
  speed: 400
});

and then I have some hypothetical UI that slows it down:

const slowModeClicked = function(event) {
  const swiper = document.querySelector('.swiper').swiper;
  swiper.speed = 1000;  // HOW DO I GET THIS TO STICK?
}

I tried adding a call to swiper.update() but that didn't work either. Is it supported?

swiper.params.speed = 1000;
