I was having the same issue. All of my bundle ids were what it was suppose to be. Additionally, I don't use Health capability. So, I just deleted the WatchOS target, then add it again to the project. You have to write the product name and organization identifier when you are adding it, right? I've realize that the organization identifier that Xcode automatically fills and the parent app's bundle id are different. I corrected the organization identifier and my problem was solved.
