在SwiftUI中沿路径进行颜色渐变填充

import SwiftUI

struct ContentView: View {
    var body: some View {
        // 创建一个视图
        Path { path in
            // 绘制路径
            path.move(to: CGPoint(x: 0, y: 0))
            path.addLine(to: CGPoint(x: 100, y: 0))
            path.addLine(to: CGPoint(x: 100, y: 100))
            path.addLine(to: CGPoint(x: 0, y: 100))
            path.closeSubpath()
        }
        .fill(LinearGradient(
            gradient: Gradient(colors: [.red, .blue]),
            startPoint: .leading,
            endPoint: .trailing
        ))
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
