NSColorComponents is a Swift extension to NSColor that provides easy access to the RGB and HSB components of an NSColor.

Configure your Podfile to use NSColorComponents:

platform :osx
use_frameworks!

target 'MyApp' do
  pod 'NSColorComponents', :git => 'https://github.com/jeffreymorganio/nscolor-components'
end

The NSColorComponents extension to NSColor adds properties that return tuples of the red, green, blue and alpha components and the hue, saturation, brightness and alpha components.

The CGFloatRGB property returns a tuple of the red, green, blue and alpha components as CGFloat values between 0 and 1:

if let (red, green, blue, alpha) = NSColor.redColor().CGFloatRGB {
  ...
}

The IntRGB property returns a tuple of the red, green, blue and alpha components as Int values between 0 and 255:

if let (red, green, blue, alpha) = NSColor.redColor().IntRGB {
  ...
}

The CGFloatHSB property returns a tuple of the hue, saturation, brightness and alpha components as CGFloat values between 0 and 1:

if let (hue, saturation, brightness, alpha) = NSColor.redColor().CGFloatHSB {
  ...
}

The IntHSB property returns a tuple of the hue, saturation, brightness and alpha components as Int values between 0 and 255:

if let (hue, saturation, brightness, alpha) = NSColor.redColor().IntHSB {
  ...
}
