ios - Zendesk iOS SDK [错误：“与 pid 87 上名为 com.apple.commcenter.coretelephony.xpc 的服务的连接在此进程中无效。”]

Question

尝试按照他们的文档实现 ZenDesk iOS SDK：

https://developer.zendesk.com/documentation/zendesk-web-widget-sdks/sdks/ios/getting_started/#show-the-conversation

聊天界面未如文档中所述显示，而是出现错误

[Client] Updating selectors after delegate removal failed with: Error Domain=NSCocoaErrorDomain Code=4099 "
The connection to service on pid 87 named com.apple.commcenter.coretelephony.xpc was invalidated from this process." 
UserInfo={NSDebugDescription=
The connection to service on pid 87 named com.apple.commcenter.coretelephony.xpc was invalidated from this process.}

我们使用： Xcode 版本：12.5.1 Swift 版本：5.4.2

这个错误有什么解决办法吗？
