SwiftUI网格图片点击右侧显示及音效播放实现问题（为自闭症儿子开发首应用）

这是我首次尝试用Swift开发应用，目标是给患有自闭症的儿子做一款简单的辅助APP。核心需求：

• iPad左侧展示喜爱物品的网格列表，点击左侧物品后，对应图片要在右侧区域显示
• 点击左侧网格里的图片，或者右侧显示的图片，都能播放该物品名称对应的音效

目前已经完成了部分开发，但右侧还是占位图片，现在卡在两个问题上：

1. 实现左侧网格按钮点击后，对应图片在右侧显示
2. 确保右侧显示的图片点击时可播放对应音效

附上当前代码：

    static let instance = SoundManager()

    enum SoundOption: String {

        } catch let error {
            print("Error playing sound. \(error.localizedDescription)")
