Step 1
We need to draw something.
Something insanely fantastic!
Well, for example... a blot.

Step 2
We transfer this magnificent blot to Xcode.
We use Path.
Don't forget about Bezier curves.

Step 3
The blot must be the most beautiful blot in the world!
Gradient will help us here.

Step 4
The blobs come in different sizes.
GeometryReader will help us with this.

Step 5
It would be necessary to revive the blot.
We use animation.

Step 6
Let our blot be attached to the function.

Step 7
Enjoy the mind-blowing blot!
