What do I do with CocoaPods in Swift 3?

I keep trying to follow his instructions and it didn't work with Swift 3, if I use Swift 2, I won't be able to run the app. But if I do, I get a bunch of errors from the framework. Does anyone have any ideas what I should do for Swift 3 and iOS 10?

With Swift 3 you have to download the version 2.0.1 in the Podfile, here you have all the content of the Podfile:

# Uncomment the next line to define a global platform for your project
 platform :ios, '9.0'

target 'VendingMachine' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for VendingMachine
    pod 'Hue', "2.0.1"

end

then the framework isn't throwing more errors, but the content for the function applyBackgroundGradient for swift 3 and hue 2.0.1 is this:

    func applyBackgroundGradient() {
        let lightGray = UIColor.gray
        let darkGrey = UIColor(hex: "#1E2428")
        let gradientLayer = [lightGray, darkGrey].gradient()

        gradientLayer.frame = view.bounds

        gradientLayer.locations = [0.0, 0.5]

        view.layer.insertSublayer(gradientLayer, at: 0)
    }

finally call the function in the viewDidLoad and you have nice gradient as background.

Thanks Roger, that answer was spot on!

I had to update Hue and change the syntax as you demonstrated above.
