Hello ! I'm trying to set your gradient via viewdidappear, but it doesn't work

ExampleOfCode:
viewDidAppear(_ animated: Bool) { self.view.layer.addSublayer(Gradients.coupDeGrace.layer) }

Gradients such as "elegance", "raccoonBack", "aboveClouds", etc... do not produce a colour, whereas the more simple ones such as "purpleDivision", "aquaSplash", "warmFlame" etc... do produce a colour as expected.
Any idea why?

Support Swift 4.2

☁️ Add Gradients example project with IGListKit

cochitiLake and cleanMirror are both the same gradients.

Hello,
your library seems no longer works on iOS 12.
Can you verify?

The data in the locations set by slickCarbon has a value greater than 1, causing the image to be blank when generating the image.
The following is how to generate images through layers：
`extension Gradients {
func imageFrom(size: CGSize, scale: CGFloat = UIScreen.main.scale) -> UIImage? {

    guard size != .zero, scale != 0 else {
        return nil
    }

    let layer = self.layer
    let rect = CGRect(origin: .zero, size: size)
    layer.bounds = rect
    layer.sublayers?.forEach({
        $0.bounds = rect
    })
    
    let format = UIGraphicsImageRendererFormat()
    format.scale = scale

    let renderer = UIGraphicsImageRenderer(size: size, format: format)

    let image = renderer.image { contentx in
        if let sublayers = layer.sublayers, !sublayers.isEmpty {
            for sub in sublayers {
                sub.render(in: contentx.cgContext)
            }
        } else {
            layer.render(in: contentx.cgContext)
        }
    }
    return image
}

}`

I got this problem after pod install (ios12, swift 4.2)
