SwiftUI Widget iOS 14 渐变问题

Question

我想使用自定义颜色为我的小部件创建渐变颜色。而且我只使用两种颜色时出现问题，结果没有应用一种颜色，而是背景变成绿色！

struct WeatherWidgetMediumView: View {
    
    var gradient: LinearGradient {
        LinearGradient(
            gradient: Gradient(
                colors:
                [
                    Color(red: 96.0/255.0, green: 171.0/255.0, blue: 239.0/255.0),
                    Color(red: 163.0/255.0, green: 230.0/255.0, blue: 244.0/255.0)
                ]),
            startPoint: .top,
            endPoint: .bottom)
    }
    
    var body: some View {
        GeometryReader { geo in
            HStack(alignment: .center) {
                Divider().background(Color.black).padding(.vertical, 16.0).opacity(0.1)
            }
        }
        .background(gradient)
    }
}

但是如果我再添加一种颜色，它看起来很棒。

struct WeatherWidgetMediumView: View {
    let weather: Weather
    
    var gradient: LinearGradient {
        LinearGradient(
            gradient: Gradient(
                colors:
                [
                    Color(red: 96.0/255.0, green: 171.0/255.0, blue: 239.0/255.0),
                    Color(red: 96.0/255.0, green: 171.0/255.0, blue: 239.0/255.0),
                    Color(red: 163.0/255.0, green: 230.0/255.0, blue: 244.0/255.0)
                ]),
            startPoint: .top,
            endPoint: .bottom)
    }
    
    var body: some View {
        GeometryReader { geo in
            HStack(alignment: .center) {
                Divider().background(Color.black).padding(.vertical, 16.0).opacity(0.1)
            }
            Spacer()
        }
        .background(gradient)
    }
}

我在我的应用程序中遇到了确切的问题，我通过在背景修饰符后添加 .blendMode(.darken) 来修复它。我希望这也能解决你的问题。
