This seems like a ton of code just to make it a little easier to create colors; am I missing something?

If I want to create a light blue color, all that I have to do is this:

UIColor(red: 3/255.0, green: 169/255.0, blue: 244/255.0, alpha: 1.0)

Am I missing something, or does this video just explain how to not write UIColor and 255.0 after each color value?

This is the video I'm referring to.

No. I think you are right. You have to.

Just because this method only accepts values of R,G & B in the range of 0.0 to 1.0, while the color values ranges from 0.0 to 255.0. So, to convert the range of (0 to 255) to (0 to 1), you simply have to divide that with 255.0
