>> Your assertion in the first paragraph is not actually true. Go to Central Park or somewhere else with no nearby WiFi beacons and try it out. Your test app will not fall back to GPS accuracy. I have done this That's not what I said, nor what the documentation said. From the documentation: The system always tries to give you the best location data that is available, but these properties give the system the flexibility to turn off hardware elements when they are not needed. For example, if you set the desired accuracy to kCLLocationAccuracyKilometer, the system might disable GPS and use only the Wi-Fi hardware, which would save power and still give you a greater accuracy than you requested. In other words: the system will not promote the returned accuracy if the data it has is already within the accuracy you asked for, but it will still fall back to whatever source of location data available, possibly higher accuracy, if no lower-accuracy source is available. This makes a lot of sense, because it is much more common to only have a GPS signal, and no cell tower or WiFi geolocation (e.g. when doing outdoor activities) than the other way around. In that case your '1 km accuracy' app might in fact get you GPS accuracy. But if you are in Central Park, you will most definitely get location data from cell towers, so in that case your app will not promote the accuracy since you didn't ask for it. Ergo, if you need the highest accuracy, you have to ask for it. The documentation makes it very clear the accuracy parameter is not a tool to force a specific accuracy, but to allow the system to relax accuracy in favor of lower power consumption, if your app doesn't need it. Not trying to be snarky here, but in this particular case it seems the problem is not in the documentation, but in your reading comprehension of it. Unless of course there is a bug in CoreLocation, or you got so unlucky when you tested in Central Park, that there was somehow not even a GPS signal available.
