IIRC, mobileSensorReading() returns an array so you need to check the keys of the array.
if tSensorData["latitude"] is empty then

I can run the simulation and show that it?s working in a general way. Furthermore, mobileSensorAvailable("location?) responds in the simulated app, saying the sensor is ?authorizedWhenInUse?

I have set the location in the simulator to a (genuine) custom location, but if I choose one of the built-in locations, I still get the same result.
