How do you use " let newSwiftColor = UIColor(red: 255, green: 165, blue: 0, alpha: 0)?

Since you're creating a new variable that contains a reference to a UIColor (newSwiftColor), it would just be:

calcbutton.layer.borderColor = newSwiftColor.CGColor

Note that Colors in UIKit are specified using floats from 0..1 not ints from 0..255, so you need to divide all your RGB values by 255.0:

let newSwiftColor = UIColor(red: 34.0/255.0, green: 167.0/255.0, blue: 239.0/255.0, alpha: 0)
