|TL;DR||Click the Debug -> Location -> Apple menu.|
|Versions:||OS X 10.10.2||Xcode 6.1.1||iOS SDK 8.0||iOS Simulator 8.1 (550.3)|
I often reset the iOS Simulator to quickly wipe out installed apps, settings, keychain items, etc. After a reset maneuver, the simulator often refuses to deliver the the users current location. I usually have a Custom Location (as pictured in the screenshot to the right) configured to get back to the same place every run.
When the simulator gets stuck, a quick workaround is to change the location to a pre-defined one, e.g. Apple. It kind of feels like Han Solo smacking the Millennium Falcon to get it to power on in Empire Strikes Back!
Just click the Debug -> Location -> Apple menu.
