CAGradientLayer in SwiftUI

Question

我正在将我的项目转换为SwiftUI，并使用带有渐变的背景。我不知道如何将下面的内容转换为SwiftUI视图：

let layer = CAGradientLayer()
layer.colors = [
  UIColor(red: 0.165, green: 0.224, blue: 0.314, alpha: 1).cgColor,
  UIColor(red: 0.112, green: 0.17, blue: 0.26, alpha: 1).cgColor]

layer.locations = [0.45, 1]
layer.startPoint = CGPoint(x: 0.25, y: 0.5)
layer.endPoint = CGPoint(x: 0.75, y: 0.5)
layer.transform = CATransform3DMakeAffineTransform(CGAffineTransform(a: 0, b: 0.46, c: -0.46, d: 0, tx: 0.73, ty: 0.68))
layer.bounds = view.bounds.insetBy(dx: -0.5*view.bounds.size.width, dy: -0.5*view.bounds.size.height)
layer.position = view.center
view.layer.addSublayer(layer)

我尝试了以下几种方法，但结果并不相同：

LinearGradient(gradient: Gradient(colors: [Color("BackgroundNEWTop"), Color("BackgroundNEWBottom")]), startPoint: .top, endPoint: .bottom))

在测试了您的UIKit代码之后，这是我在SwiftUI中复制的最接近的代码。我在这里包含了结果图像，但是您应该先尝试这段代码，因为在线图像看起来可能略有不同。

示例代码和图像如下：

struct SampleView: View {
  let color1 = Color.init(red: 0.112, green: 0.17, blue: 0.26)
  let color2 = Color.init(red: 0.165, green: 0.224, blue: 0.314)
  var body: some View {
    ZStack {
        LinearGradient(colors: [color1, color2],
                       startPoint: UnitPoint(x: 0.75, y: 0.5),
                       endPoint: UnitPoint(x: 0.25, y: 0.5))
    }
  }
}
