I need to reset the iPhone Simulator a lot, and haven't found a way to do it without using the mouse. It's a small thing, but I'm really sick of doing it and would love to have a way to do this using a keyboard shortcut.
Even better would be a way to reset it from the command line, so I could build a reset into a deploy script.
I am not very familiar with iOS or MacOS.
Just run this in the terminal:
xcrun simctl shutdown all && xcrun simctl erase all
Another approach suggested by @txulu, before erasing the simulator kill the process:
killall "Simulator" 2> /dev/null; xcrun simctl erase all
Unable to erase contents and settings in current state: Booted Maybe there is something else I can pipe before/after your command to shutdown/reboot sim ? –

Keli In Xcode 6, DO NOT JUST DELETE THE FOLDER FOR THE SIMULATOR! It WILL screw things up, and it WILL cause you a headache.
In Xcode 6, there's actually a tool to control the simulator from the command line.
Make sure your command line settings are set to Xcode 6
xcrun simctl
In Xcode 6, each device has a GUID/UUID associated to it, to reset a specific device, you need the GUID for it.
The command
xcrun simctl list
will show you all of the devices you have set up. The output will look like this:
== Devices ==
-- iOS 7.0 --
iPhone 4s (F77DC0AE-6A6D-4D99-9936-F9DB07BBAA82) (Shutdown)
iPhone 5 (5B78FC0D-0034-4134-8B1F-19FD0EC9D581) (Shutdown)

Just copy the GUID from inside the parentheses, and run xcrun simctl erase
for example,
xcrun simctl erase 5B78FC0D-0034-4134-8B1F-19FD0EC9D581
would erase the iOS 7.0, iPhone 5 device
all argument. So you can erase all simulators with xcrun simctl erase all –
Anastassia Thought I'd post this for anyone who runs into the same need. Someone on reddit gave me this solution (which I tested and it works great). Note that this time you need an ellipsis after "Settings", not three periods (weird).
This is an AppleScript that can be invoked from the command line to reset the Simulator:
tell application "iPhone Simulator"
activate
end tell
tell application "System Events"
tell process "iPhone Simulator"
tell menu bar 1
tell menu bar item "iOs Simulator"
tell menu "iOs Simulator"
click menu item "Reset Content and Settings…"
end tell
end tell
end tell
tell window 1
click button "Reset"
end tell
end tell
end tell
Save as /path/to/script and invoke with:
osascript /path/to/script
FunctionalTests/script:34:49: execution error: File iPhone Simulator wasn’t found. (-43), and FunctionalTest/ is the folder where script is –
Anarthria "System Events got an error: Can’t get button "Reset" of window 1 of process "Simulator". and switching it to click button 1 yields the same results –
Ostium I checked it with XCode 9. To close all active simulators run:
xcrun simctl shutdown all
To reset all simulators run:
xcrun simctl erase all
You can filter what simulator to close/reset like this:
xcrun simctl shutdown F36B238F-3ED6-4E10-BB5A-0726151916FA
xcrun simctl erase F36B238F-3ED6-4E10-BB5A-0726151916FA
Find all accessible simulators (and their GUID) on your machine like this:
xcrun instruments -s
To run any simulator by GUID:
xcrun instruments -w F36B238F-3ED6-4E10-BB5A-0726151916FA -t Blank
To install app to the booted simulator:
xcrun simctl install booted /path/to/your.app
To remove app from the booted simulator:
xcrun simctl uninstall booted /path/to/your.app
To launch the app in the booted simulator:
xcrun simctl launch booted "com.app.bundleIdentifier"
"com.app.bundleIdentifier" is your CFBundleIdentifier in Info.plist
COPY-PASTE ANSWER - note: will reset the contents and settings of all available simulators.
Thanks @Alpine for the inspiration and knowledge. If you run this in your command line you should be able to reset all the available sims. This works with Xcode 6.
# Get the sim list with the UUIDs
OUTPUT="$(xcrun simctl list)"
# Parse out the UUIDs and saves them to file
echo $OUTPUT | awk -F "[()]" '{ for (i=2; i<NF; i+=2) print $i }' | grep '^[-A-Z0-9]*$' > output.txt
# Iterate through file and reset sim
for UUID in `awk '{ print $1 }' output.txt`
do
xcrun simctl erase $UUID
done
xcrun simctl list | awk -F "[()]" '{ for (i=2; i<NF; i+=2) print $i }' | grep '^[-A-Z0-9]*$' | xargs -I uuid xcrun simctl erase uuid –

And you're good to go.
Upon installing Xcode I always create a keyboard shortcut for "Reset Content and Settings" in the simulator. An extremely useful time saver.
System Preferences > Keyboard > Shortcuts > App Shortcuts > "+"
In the Application picker, select "Other..." to open the app picker dialog.
In this dialog you're unable to "Show Package Contents" to explore a .app, so you'll need to use Go to Folder via Cmd-Shift-G. (First open the application drop down and select Other)
In the current version of Xcode, go to the path:
/Applications/Xcode/Contents/Developer/Applications
Select Simulator.app and press "Add"
For Menu Title, enter Reset Content and Settings...
For Keyboard Shortcut, press CMD-Shift-R
The keyboard short-cut solution is not relevant anymore and unfortunately @Cameron solution didn't work for me either (I tried to debug it with no luck)
Here is what works for me:

Eupatrid I wrote a script that will reset the contents & settings of all versions and devices for the iOS Simulator. It grabs the device names and version numbers from the menu, so it will include any new devices or iOS versions that Apple releases simulators for.
It's easy to run manually or use in a build-script. I would suggest adding it as a Pre-Action Run Script before the build.
It's based heavily on Stian's script above, but doesn't become stale with new iOS versions, and eliminates the dialog box (better for automation build scripts and working from the command-line).
I have found this very helpful tool called "SimulatorManager": http://tue-savvy.github.io It will reset all you simulators by means of a menu bar widget (not sure if that's what its called) but on top of that it will give you quick access to all your application data. I really can't live without it anymore. Spread the word!
I want to add something to Cameron Brown's answer. To make sure the correct version is resetted (e.g, iPad, version 6.1), I start the iOS Simulator via ios-sim:
version=$(echo "$DESTINATION" | egrep -o "OS=[0-9.]{3}" | cut -d '=' -f 2)
simType=$(echo "$DESTINATION" | egrep -o "name=[a-zA-Z]*" | cut -d '=' -f 2 | tr "[A-Z]" "[a-z]")
IOS_SIM_BIN=$(which ios-sim)
if [ -z $IOS_SIM_BIN ]
then
echo "ios-sim not installed, please use 'sudo npm install ios-sim -g'"
fi
echo "Resetting Simulator \"$simType\", version \"$version\""
$IOS_SIM_BIN start --family $simType --sdk $version --timeout 1
osascript /path/to/reset_simulator.applescript
$DESTINATION can be e.g "OS=7.0,name=iPad".
For that to work correctly, I adapted the reset_simulator.applescript a bit and removed the activation part:
tell application "iPhone Simulator"
activate
end tell
As an added bonus to using the xcrun commands you can launch a device after you listed with
xcrun simctl list
Once you have the list displayed run:
xcrun instruments -w "iPhone 5s (8.1 Simulator) [31E5EF01-084B-471B-8AC6-C1EA3167DA9E]"
We use the following python script to reset the simulator on our build server.
#!/usr/bin/env python
import subprocess
import re
import os
def uninstall_app():
print 'Running %s' % __file__
# Get (maybe read from argv) your bundle identifier e.g. com.mysite.app_name
try:
bundle_identifier = '$' + os.environ['BUNDLE_IDENTIFIER']
except KeyError, e:
print 'Environment variable %s not found. ' % e
print 'Environment: ', os.environ
exit(1)
print 'Uninstalling app with Bundle identifier: ', bundle_identifier
# We call xcrun, and strip the device GUIDs from the output
process = subprocess.Popen(['xcrun', 'simctl', 'list'], stdout=subprocess.PIPE)
# Read first line
line = process.stdout.readline()
while True:
# Assume first match inside parenthesis is what we want
m = re.search('\((.*?)\)', line)
if not (m is None):
# The regex found something,
# group(1) will throw away the surrounding parenthesis
device_GUID = m.group(1)
# Brutely call uninstall on all listed devices. We know some of these will fail and output an error, but, well..
subprocess.call(['xcrun', 'simctl', 'uninstall', device_GUID, bundle_identifier])
# Read next line
line = process.stdout.readline()
# Stop condition
if line == '':
break
if __name__ == '__main__':
uninstall_app()
It assumse your app's bundle identifier is set as an environment variable, e.g.
export BUNDLE_IDENTIFIER=com.example.app_name
maybe you'd want to pass the bundle identifier in another way.
Building on most of the answers above, I am using Keyboard Maestro and made a little Macro to reset the currently running Simulator and restarting it.
It turns the focus back to Xcode after resetting and restarting, so I can hit Command+R again right away to re-run the app, which I find very convenient.
The content of the ruby script is:
#!/usr/bin/env ruby
list = `xcrun simctl list`.split("\n")
list.each do |line|
if line =~ /\(Booted\)$/
device = line.match(/([^(]*)\s+\(([^)]*)\)\s+\(([^)]*)\).*/)[1]
uuid = line.match(/([^(]*)\s+\(([^)]*)\)\s+\(([^)]*)\).*/)[2]
status = line.match(/([^(]*)\s+\(([^)]*)\)\s+\(([^)]*)\).*/)[3]
puts uuid
break
end
end
Here's a Rakefile task to reset a targeted simulator. This works with Xcode 7 since the Xcode 7 command line tools broke the xcrun simctl uninstall command. I have a little custom runC method since I like to see the actual terminal command as well as its output.
desc "Resets the iPhone Simulator state"
task :reset_simulator => [] do
deviceDestinationName = 'iPhone 6' #for efficiency since we only target one device for our unit tests
puts "...starting simulator reset"
runC('killall "iOS Simulator"')
runC('killall "Simulator"')
runC('xcrun simctl list > deviceList.txt')
lines = File.open('deviceList.txt').readlines
lines.each do |line|
lineStripped = line.strip
if (lineStripped=~/[a-zA-Z0-9]{8}-[a-zA-Z0-9]{4}-[a-zA-Z0-9]{4}-[a-zA-Z0-9]{4}-[a-zA-Z0-9]{12}/)
if (lineStripped !~ /unavailable/ && lineStripped.include?("#{deviceDestinationName} ("))
puts "Inspecting simulator: #{lineStripped} by making sure it is shut down, then erasing it."
needsShutdown = !lineStripped.include?('Shutdown')
aDeviceId = lineStripped[/[a-zA-Z0-9]{8}-[a-zA-Z0-9]{4}-[a-zA-Z0-9]{4}-[a-zA-Z0-9]{4}-[a-zA-Z0-9]{12}/]
if (needsShutdown)
runC("xcrun simctl shutdown #{aDeviceId}")
end
runC("xcrun simctl erase #{aDeviceId}")
#does not work to just uninstall the app with Xcode 7, do just rely on resetting the device above
#`xcrun simctl uninstall #{aDeviceId} com.animoto.AppServiceClientTester`
end
end
end
runC('rm deviceList.txt')
end
#Runs a command and prints out both the command that will be run and the results
def runC(command)
puts '$ ' + command
puts `#{command}`
end
Just one liner command : Loop through each simulator in Devices folder and erase.
for id in $(xcrun simctl list devices | grep -E '([0-9A-F]{8}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{12})' -o); do xcrun simctl erase $id; done
paste it in Terminal and hit return.
Breaking it down:
target names and Simulator app name seem to have changed a bit to xCode6 / iOS8. Here is un updated version of Cameron Brown's osascript for xCode6 / iOS8:
tell application "iPhone Simulator"
activate
end tell
tell application "System Events"
tell process "iPhone Simulator"
tell menu bar 1
tell menu bar item "iOs Simulator"
tell menu "iOs Simulator"
click menu item "Reset Content and Settings…"
end tell
end tell
end tell
tell window 1
click button "Reset"
end tell
end tell
end tell
