I can add that the app connects with a server that we run, which has a valid SSL certificate. One user who had this problem said "The iPads have the latest software updates installed (14.5.1) as well as the organisations SSL certificate as the error message indicates". I don't know what "organizations SSL certificate" he is referring to; it is not the SSL certificate on my server. Could some custom certificate he has on his device be interfering with its ability to use my server?

Yes this works, thanks. I guess range(of:) is an old NSString function that is available, but not documented in Swift.

I'm doing this layout within the context of a tableview cell, so I don't really have access to view controller events. As far as I know there's no opportunity within a table cell to take action after layout has occurred. The sizes of the UI elements if examined in awakeFromNib are the same as they are in the Nib file, which is not what they end up being after they are rendered within the tableview.

I also made sure to use the "conserve power" priority and the "background" notification type when posting the notification.

OK, well, I rebooted my phone on a whim, and now it's working.

Thanks for the response. This is certainly a disappointment. My goal is to count the number of floors a person can climb or descend within a time limit such as one minute. I was assuming that the pedometer would be able to give me fractional values instead of just whole numbers of floors. I was also under the impression that these functions use the motion sensor rather than GPS to figure out what the person is doing. Is there another way I can accomplish my goal? If I know that the person is climbing stairs, can I just use the step counter? Frank

I had to manually add the Privacy manifest file to the build under Build Phases -> Copy Bundle Resources. It would be nice if Xcode would do this automatically.

Thanks for the response. This person has a published app in the app store, so I assume he joined the developer program as an individual.

Ok, never mind. The problem is that I needed to configure my Apple team ID and bundle ID somewhere in Auth0 that was hidden under an "advanced setup" tab and not discussed in their documentation. So this is a fail for them, not us.
