如何在 SwiftUI 中应用内阴影和投影

从 iOS16 开始，现在可以在里面添加阴影。

内心的阴影

import SwiftUI

struct ContentView: View {
    private let baseColor: Color = .init(red: 232/255, green: 232/255, blue: 232/255)
    
    private let shadowColor: Color = .init(red: 197/255, green: 197/255, blue: 197/255)
    
    var body: some View {
        RoundedRectangle(cornerRadius: 10)
            .fill(baseColor.gradient.shadow(.inner(color: shadowColor, radius: 8, x: 20, y: 20)))
            .frame(width: 300, height: 300)
    }
}

投影

import SwiftUI

struct ContentView: View {
    private let baseColor: Color = .init(red: 232/255, green: 232/255, blue: 232/255)
    
    private let shadowColor: Color = .init(red: 197/255, green: 197/255, blue: 197/255)
    
    var body: some View {
        RoundedRectangle(cornerRadius: 10)
            .fill(baseColor.gradient.shadow(.drop(color: shadowColor, radius: 8, x: 20, y: 20)))
            .frame(width: 300, height: 300)
    }
}
