Type 'CAGradientLayerType' (aka 'NSString') has no member 'conic'

Question

I'm trying to use the new conic gradient type. I've set the deployment target to 12.0 and added the QuartzCore framework, and I'm setting the type of a gradient to .conic:

    let gradient = CAGradientLayer()
    gradient.type = CAGradientLayerType.conic

I can even click through to the documentation:

extension CAGradientLayerType {
    ...

    /* Conic gradient. The gradient is centered at 'startPoint' and its 0-degrees
     * direction is defined by a vector spanned between 'startPoint' and
     * 'endPoint'. When 'startPoint' and 'endPoint' overlap the results are
     * undefined. The gradient's angle increases in the direction of rotation of
     * positive x-axis towards positive y-axis. */

    @available(iOS 12.0, *)
    public static let conic: CAGradientLayerType
}

but I'm still getting this build error:

Type 'CAGradientLayerType' (aka 'NSString') has no member 'conic'

Thanks to this answer looks like the issue was my swift language version (Target > Build Settings > Swift Language Version). It needs to be version 5 to use this syntax. Otherwise, I guess we would need to treat that property as a string, and set it to kCAGradientLayerConic.
