My app uses the location service. To test what is happening when the user presses 'Don't allow' when the simulator asks for the permission to access the location service (when the app is started for the first time) I need to reset the simulator. This because the question was answered at the beginning of the development process with allow. So no more questions are asked.
Resetting the Simulator with "Resetting Content and Settings.." don't bring back the question at the start. What I am doing wrong?
Within the iPhone/iPad simulator, go to the top-menu and select "Simulator" -> "Reset Content and Settings..."
(In earlier versions of the simulator the top menu entry label was "iOS Simulator"
For iOS 11 and newer, you need to go the top system menu and select:
"Hardware" > "Erase All Contents and Settings..."
If you're using Snow Leopard:
Go to your mac's System Preferences (not the simulator's), Select the Security section. Hit the "Reset Warnings" button in front of Location Services, you're all set.
Apple says
To set the user content and settings of the simulator to their factory state and remove the applications you have installed, choose iPhone Simulator > Reset Content and Settings.
Nice and handy tool. The great Fastlane commandline tools (https://github.com/fastlane/snapshot)
snapshot reset_simulators
reset_simulators is removing all simulators and create new one only for the latest iOS version. If you want to recreate simulators for other versions you have to provide the list of the versions after the --ios argument, e.g.
snapshot reset_simulators --ios 8.3,8.4,9.0,9.1
I tried "Erase All Content and Settings" in Simulator 10.0, but it didn't work. What worked for me is that in Simulator 10.0, the Settings app is built in. You can reset by:
- Clicking on the Settings app to start it.
- Click General.
- Click Reset.
- Click Reset Location & Privacy.
- Click Reset Warnings.
Then your authorization status will be reset to .notDetermined.
Or you can choose simctl to manage iOS simulator in Command Line.
$ xcrun simctl erase all is too erase all content in all simulator.
