如何解决使用 WheelPickerStyle() 时 Catalyst 应用程序崩溃

我有一个用 SwiftUI 编写的应用程序的 Catalyst 版本。有一个选择器，我想将它的样式设置为 WheelPickerStyle()。 Mac Catalyst 支持 WheelPickerStyle()： https://developer.apple.com/documentation/swiftui/wheelpickerstyle 在启动应用程序崩溃。对于其他样式，一切正常。

2021-05-20 11:04:48.341319+0300 Н или НН[2745:66389] [General] UIPickerView is not supported when running Catalyst apps in the Mac idiom.
