How to change the speed of the physical world for particle effects in a Sprite set?

Question

I created particle effects using an editor, but my application runs in all code (Swift). When I change the speed of the physical world, all my physical bodies slow down. But when I make my particles in a physical body, they will not suffer from a change in speed, although they must be part of the same world of physics. I made the particles be dynamic and subject to gravity, and still nothing. I even tried to give them bitMaskCategory, where they really suffered from my gravitational nodes, however they are still not affected by physics. World.speed.

Does anyone have an idea how to do this? I know that this is possible, but I am missing something. I really do not want to create separate gravitational nodes for particles to simulate the speed of the rest of the world.
