快速用户界面问题！"通话中的额外参数"

Question

我现在正在学习SwiftUI，我发现了一个问题，我不知道如何处理它。

每当我想添加更多的按钮操作时，总会有一个警报显示"调用中有额外的参数"。我发现了一些使用组的想法，但我不知道如何编写代码。有人能帮我吗？谢谢

如果不是复制粘贴，则错误为

Button("10") {
let selectionFeedback = UISelectionFeedbackGenerator()
selectionFeedback.selectionChanged()
self.show2010.toggle()
}
.buttonStyle(YearRoundedButton())
_10L()                         // << here !!

如果看起来像(基于常见的图案(你错过了。
