I have a ton of iOS simulators on my machine and I know that one of them has a certain app installed on it that I want to run again (and I can't easily rebuild this app on a different simulator). How can I find which simulator has a certain app installed on it?
I was able to get what I wanted by running the following commands in Terminal:
cd ~/Library/Developer/CoreSimulator/Devices
find . -name MyAppName.app
Then I went into the folder for the device with the app and opened device.plist which has name and iOS version of that simulator, which I could then open from the Simulator app Hardware > Device menu.

I've been having hard times with my old Windows laptop while developing React Native apps so I moved to MacOS laptop. I installed Android Studio and Xcode (including Xcode command line tools). Then I initialized a blank expo managed project. I started both on Android Emulator and iOS simulator. Android one worked out with an ádb´ error (or maybe warning). But on the other hand, iOS simulator did nothing. There's no Expo Go app installed on iOS device, so it can not launch my app using it. I don't get any error or warning related to this problem, so I can't trace the problem.
I have tried deleting global expo folder located at ´~/.expo/´, I also tried to give 777 (all permissions) on that folder to my current user.
I tried uninstalling and reinstalling expo package globally.
I made sure I have selected Xcode command line tools on ´Xcode -> Preferences -> Locations -> Xcode 13.2.1 (13C100)´
I tried to launch different iOS devices like (iPhone 6, 8, 13, iPod etc.)
I tried clearing cache and starting expo with ´sudo npm start --clear-cache´
I have been trying to solve this for at least 2 hours tried everything possibly related to my problem but none of them did work. There's one thing I don't understand though. Even though I used different iOS device simulators the Expo Metro Bundler showed this ´› Opening exp://10.42.33.15:19000 on iPhone 8´ output. I have tried iPhone 13, iPhone 6, iPod etc. but this was the same output for different devices. Here's some screenshot related to probem:

This tutorial video on YouTube helped me solve my problems. I think I was missing a few things:
I haven't granted required privacy permissions on my Mac for Xcode, Android Studio and VS Code. Open System Preferences > Security & Privacy > Go Privacy Tab > Give Full Disk Access to Xcode, VS Code, Android Studio, Terminal and Watchman (Watchman is not required, but I have also installed it for solving a problem before)
You should to launch both your Android and iOS simulators before starting your expo application. Simply go to Android Studio and launch your device. To launch iOS device use bash and type open -a simulator.
If you don't have Expo Go app installed on your iOS simulator then you should first install it before starting your expo app. To install it use expo client:install:ios command.
Start your app by using expo start command. Type i and a or click on Run on iOS simulator and Run on Android device/emulator buttons to launch your app on devices.
NOTE: If you app gets stuck at New update available, downloading... stage then you can start your expo app with cleaned cache using expo start -c command. It was helpful for me.
NOTE 2: You may need to use sudo command on some of the commands I've mentioned, I'm not sure which ones are required or not.
I run into the same issue every time when I tried to set it up on a new laptop.
Its fixed after the installation of xCode cli.
Take a look at this - https://docs.expo.dev/workflow/ios-simulator/
I fixed similar issue by hard restarting simulator
Top menu -> Device -> Erase All Content And Settings...
Here's my Environment
Xcode Version: 11.1 (11A1027)
Physical device: - iPad mini 2 (IOS 12.4.2)
VSCode Version: 1.39.2
Flutter version: 1.9.1+hotfix.6
When I use the iOS part of the Flutter project and run it physical device using XCode, it detects the device and works fine but I am somehow not able to see the device on the available devices section on VSCode.
However VSCode detects and works fine with the simulator.
I also ran flutter doctor to see connected devices, but again it does not show the connected physical devices but shows the simulator created device.
Use rm -rf <flutter_repo_directory>/bin/cache to force delete the files in cache and then flutter doctor -v to reinstall the missing sdk directories.
Deleting the cache in flutter/bin/cache directory and then reinstalling the dart sdk solved this issue.
Referred to this issue in Flutter repository(Issue No:41006).
I had the same issue. In my case, a recent iOS update had turned off Developer mode, for some reason... So I needed to enable it again (Settings - Privacy & Security - Developer Mode).
iPadOS / iOS Devices Setup for Hot Reload
Before trying to flutter Debug on physical device from Vscode it is Required to first :
Run a successful Xcode build on that iOS or iPadOS device
Follow this steps if you don't know how to Run Xcode Build -> your device should then be detected by flutter :
Open Xcode & do all the classic Set Up (Signing in with a Team & choosing a UNIQUE bundle Identifier)
Set Your iPhone Auto-Lock to Never (& Unlock it !) - Connect your iPhone or iPad to Mac with USB cable & Accept Prompt on the iPhone
Run Xcode Build on your iPhone this alert prompt will select Ok
On your iPhone a new menu will have appeared - Navigate to it & Click « Verify App » or « Accept »
Now Run Xcode Build Again - if does not run try running flutter clean & flutter build ios & try running again
—
After Successful Xcode Build - Stop Running the App
Keep Xcode Open
— iOS Setup is done
Close all Simulators or Emulators - Close VsCode
run flutter devices to make sure your Device is now detected
if it’s not try Turning it off & plugging it back again - remember to accept Trust Computer Prompt - keep it device unlocked too !
Open back your project in VsCode or Android Studio
Hot Reload⚡️Using VsCode :
Press F8 or Select ▷ « Start Debugging » in main.dart
That’s it ! You now have the power of Hot Reload⚡️ with VsCode on a physical device !
Hot Reload using Terminal Commands :
run flutter run -d yourDeviceID
Have fun ! Press r in Terminal for HotReload⚡️
If you need to find your iOS device ID :
Select Add Additional Simulators
Hot Reload⚡️on Android Studio :
Select your device & run
All I had to do was to disconnect the device from the laptop, make sure VS Code is open, then connect the device again while no VS Code, then it detected right away and chose the device automatically.
Sometimes it doesn't detect the device if it is not directly connected to the computer. I had a docking station in between and it didn't recognized the device. Especially after you have updated you macOS just before.
With "focus mode" activated on the device (like "do not disturb" 🌙) it won't show up.
Check whether you have fully installed xcode by running flutter doctor -v
Incase you find that some thing like
[!] Xcode - develop for iOS and macOS
✗ Xcode installation is incomplete; a full installation is necessary for iOS development.
Download at: https://developer.apple.com/xcode/download/
Or install Xcode via the App Store.
just run install Xcode and run
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
sudo xcodebuild -runFirstLaunch
Incase you installed xcode already, just run the above commands, they will do the magic.
I followed the below process in order to install apps in IOS simulators
1.I have Test.app file with me go to Library->application support->iPhone simulator->6.1->Application->i created new folder and i placed my test.app file in that folder as of i knew after when we open the simulator we can able to see that particular app in the simulator it doesn't happened in my case
2.i followed the cd in terminal window xcrun simctl install booted (my test.app path ) it showing error that
Failed to install the requested application
An application bundle was not found at the provided path.
Provide a valid path to the desired application bundle.
and i tried with different methods which i had read in internet but nothing is working
so guide me how to install the app in IOS simulators and how to work with them.
I am using OSX Yosemite. I have installed xcode 6.1.1 recently but i can't run my code in simulator.
When i press "run" button. It shows error statement which is
"Xcode cannot run using the selected device. No supported iOS devices are available. Connect an iOS device to run your application or choose an iOS simulator as the destination"
I have tried the possible solution. I enter "Devices" page(Windows -> Devices). There is no simulator in the page. Then i click "+" to create simulator. It shows error statement which is "unable to determine SimDeviceSet, set_path=/Users/User Name/Library/Developer/CoreSimulator/Devices
I can't find this location in my computer. Even i have uninstalled and reinstalled the xcode. The location and related simulator file still can't be found.
Do you guys have any ideas about it? Many thanks!!!!!!!!!!
I had the same issue today and re-setting the developer directory made it work again for me (restart Xcode afterwards).
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
I'm currently developing a mobile app using Meteor v1.0 and trying to test iOS devices using the iOS Simulator.
For Cordova apps, I'm used to doing something like:
cordova emulate ios --target "iPad"
For Meteor, the alternative is:
meteor run ios
On my Mac, running the above Meteor command leads to the app being run on an iPhone 4S emulator. I'm unable to choose what device to emulate like I could when using Cordova.
I've tried switching device through the iOS Simulator after the app gets loaded initially but the app is not available on the device I switch to.
The only solution I have found is to navigate to the Cordova directory (.meteor/local/cordova-build) and run the iOS Simulator directly from Cordova.
Does anyone know a better solution by using Meteor itself or is this not currently possible? I haven't been able to find anything in the documentation. I'm open to testing it using something else but it would be nice to keep everything together with Meteor.
The current solution is to open Xcode by running meteor run ios-device and then select the correct simulator inside Xcode. Unfortunately, ios-sim (the package Meteor uses for the simulator) doesn't make it easy to select the device to simulate.
meteor run ios-device -p 3000 is what I do. Then download the phone gap app for iPad and run it on your IP:
ipconfig getifaddr en0
Then put that in on the phone gap app. So example: 192.168.0.8:3000
