我真的很难让UIActivityViewController一个UIViewControllerRepresentable在 SwiftUI 中工作。例如，当尝试分享到 WhatsApp 时，屏幕只是轻微移动，好像要发生一些动作，然后它返回到原来的位置，并出现以下一连串错误（为了便于阅读，删除了一些时间戳等）：
[core] HOST: Failed to load remote view controller with error:
Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service on pid 2539 named
net.whatsapp.WhatsApp.ShareExtension.viewservice was interrupted, but the message was
sent over an additional proxy and therefore this proxy has become invalid."
[core] Sheet not being presented, calling premature completion
[net.whatsapp.WhatsApp.ShareExtension(2.20.111)] Connection to plugin interrupted while in use.
[net.whatsapp.WhatsApp.ShareExtension(2.20.111)] Connection to plugin invalidated while in use.
这只是与使用 SwiftUI 时模态的（看似可怕的错误）行为有关吗？我似乎无法解决这个持续存在的问题。
