Getting the Display P3 values back out of a UIColor created with init(displayP3Red:green:blue:alpha:)

Color.swift

import UIKit

// Create color using P3 color space
let linearColor = UIColor(displayP3Red: 1, green: 0.5, blue: 0.2, alpha: 1)

do {
    var r: CGFloat = 0, g: CGFloat = 0, b: CGFloat = 0, a: CGFloat = 0
    linearColor.getRed(&r, green: &g, blue: &b, alpha: &a)
    print(r, g, b, a) // 1.07, 0.46, 0.0, 1.0 - not the expected values
}

// Convert to P3
let p3Color: UIColor = {
    guard let colorSpace = CGColorSpace(name: CGColorSpace.displayP3),
          let cgColor = linearColor.cgColor.converted(
            to: colorSpace,
            intent: .defaultIntent,
            options: nil
          ),
          let rgba = cgColor.components,
          rgba.count == 4
    else {
        return linearColor
    }
    // FWIW, I could actually just use these component values directly instead
    // of converting back to a UIColor to extract them again
    return UIColor(red: rgba[0], green: rgba[1], blue: rgba[2], alpha: rgba[3])
}()

do {
    var r: CGFloat = 0, g: CGFloat = 0, b: CGFloat = 0, a: CGFloat = 0
    p3Color.getRed(&r, green: &g, blue: &b, alpha: &a)
    print(r, g, b, a) // 1.0, 0.5, 0.2, 1.0 - matches the input values
