How to Convert RGB to HUE in Swift

Sometimes it’s handy to use HUE properties in apps or games to animate its saturation or brightness or even the color itself. So here is super simple func to convert RGB to HUE.

let r:CGFloat = 251/255
let g:CGFloat = 94/255
let b:CGFloat = 50/255
func rgbToHue(r:CGFloat,g:CGFloat,b:CGFloat) -> (h:CGFloat, s:CGFloat, b:CGFloat) {
let minV:CGFloat = CGFloat(min(r, g, b))
let maxV:CGFloat = CGFloat(max(r, g, b))
let delta:CGFloat = maxV - minV
var hue:CGFloat = 0
if delta != 0 {
if r == maxV {
   hue = (g - b) / delta
}
else if g == maxV {
   hue = 2 + (b - r) / delta
}
else {
   hue = 4 + (r - g) / delta
}
hue *= 60
if hue < 0 {
   hue += 360
}
}
let saturation = maxV == 0 ? 0 : (delta / maxV)
let brightness = maxV
return (h:hue/360, s:saturation, b:brightness)
}
let hueColor = rgbToHue(r: r, g: g, b: b)
let finalColor = SKColor(hue: hueColor.h, saturation: hueColor.s, brightness: hueColor.b, alpha: 1)
