I didn’t get a practical solution for the last exchange. I tried to add widget without using Intent, and found that this error disappeared.
Fortunately, this question answered. Thanks， @ iceleaf

Year, For now, it has not been solved.
My problem is slightly different from your description. I am dating widgetKit in the OC project and reported an error before the OC file was referenced. Your problem will be the next one I face.
Fortunately, we will talk with Apple technicians about this issue soon, and we will update the conclusion here
@mgoemmel Can you elaborate？
