As the error message indicates, the UIApplication class is unavailable from extensions (including WatchKit extensions). It is not possible to open a URL on the user's phone from a WatchKit extension. You should consider adopting Handoff to give the user a quick means to transition from your Watch app to your phone app.

如错误消息所示，UIApplication类不可用于扩展（包括WatchKit扩展）。无法从WatchKit扩展程序打开用户手机上的URL。您应该考虑采用Handoff来为用户提供从Watch应用程序过渡到手机应用程序的快速方法。
