Swift doc formating

My notes on method commenting in swift. IMO commenting is vital when creating complex systems. So much resolution about how the method came to be and it’s artifacts and gotchas are lost if there is no documentation in the code. I usually include massive amounts of comments in the code because when I later revisit the code a year later, my initial thinking has disappeared and I need something to jog my memory to get back into the code. I also leave references to where parts of the solution was found, like stackoverflow links or other github projects. To give credit where credit is due. Personally I use a commenting style that is closer to javadoc as a lot of people know it and it feels universal. It even renders to apples dialog boxes like bellow:

  * A method that returns awesome colors
  *   - color: only awesome colors allowed
  *   - alpha: only awesome alpha values allowed
 static func test(color:UIColor,alpha:CGFloat){
     _ = color
     _ = alpha

Hold in the alt key and press the method name from a caller. And this dialog will pop up


why you shouldn’t do comment style like this:

  When you copy this, indentation is lost

Proper comment fencing:

 * Something something
 * Example:
 * var temp = {
 *      //something indented. wow comment style keeps indentation on copy paste. such wow
 * }
