userLocation: latitude/longitude return zero?

Question

I am just looking at mapKit and decided to make a quick button to display my current location, however when I press the button my latitude/longitude always display as [0.000000]

Test it on the device. By default, on the simulator, the coordinates you get back are Apple's headquarters. Cf. doc.
