无效的WatchKit支持 - 从4月1日开始， 2018年，提交给Apple Watch App Store的所有应用必须使用watchOS 2 SDK或更高版本构建

我的问题是知道如何构建使用watchOS 2 SDK的应用程序？

推荐答案
检查部署目标。它可能只是通过使用更新版本的Xcode来更新。
Check your Deployment Target. It's likely it wasn't updated just by using a newer version of Xcode.
还可以尝试检查Watch Extension的Build Settings中的Base SDK，以确保它是最新的。
Also try checking Base SDK in Build Settings of your Watch Extension to make sure it is up to date.
