What does Core Motion error 107 mean?

Question

When I use CMPedometer pedometer appearance Error Code=107 Domain=CMErrorDomain (null) "error . what does it mean?

Answer 1

You likely moved on by now but for others, this is very likely a date issue.

My case was using QueryPedometerData() and misunderstanding FromTimeIntervalSinceNow(). I thought it meant subtracting a number of seconds from Now but where its actually the opposite.

Answer 2

I also came across with this problem. In my case, the error was caused by the fact that the start date and the end date I provided to the CMPedometer were the same (for example, start date - 12:59:59 and the end date - 12:59:59). As I set the end date manually, inclusion of nanoseconds in the end date solved the problem.
