Swift border color

Question

I want to have color border on button:

buyButton.layer.borderColor = UIColor(red: 83.0, green: 186.0, blue: 183.0, alpha: 1.0).cgColor

doesn't work for me, but

 buyButton.layer.borderColor = UIColor.blue.cgColor

works. What is wrong with my color?

Thank you

Read the doc of `UIColor(red:green:blue:alpha:)`. The wanted values needs to be between 0 and 1. so `83.0` => `83.0/255.0` — Larme, Mar 29 '17 at 13:53
Use an extension that takes `Int` instead of `CGFloat`. http://stackoverflow.com/a/24263296/669586 — Sulthan, Mar 29 '17 at 13:54

You are using 'raw' RGB values, divide them by 255.0.

buyButton.layer.borderColor = UIColor(red: 83.0/255.0, green: 186.0/255.0, blue: 183.0/255.0, alpha: 1.0).cgColor

So in UIColor terms, 1.0 is 255 red. 0.5 is 127.5 red etc.

The input values needs to be between 0 and 1, so divide them by 255.

buyButton.layer.borderColor = UIColor(red: 83.0/255.0, green: 186.0/255.0, blue: 183.0/255.0, alpha: 1.0).cgColor
