Xcode 11 的发行说明说:

The WatchKit framework is no longer included in the iOS SDK. If you’re using WatchKit APIs from iOS, you need to remove this use. The WatchKit framework remains available on watchOS. If you’re using WatchKit APIs from iOS to infer availability of features on the paired Apple Watch, include information about your use case when you submit feedback to Feedback Assistant. (49707950)

您可以将build设置更改为旧版，以便现在可以使用。

PS:旧版设置在 Xcode 12b2 中已弃用

我建议您不要使用旧版build设置。您缺少新构建系统的许多功能，并且在即将推出的 Xcode 版本中也已弃用
