ionic cordova emulate ios -l <target>
Does not work for me. I get an error suggesting that I am targeting the wrong device even though the device I am targeting is listed as a virtual device when running the command:
ionic cordova emulate --list
When I run the app with Xcode instead it works however it does not reload my edits, even if I stop and start the app again.
*** disclaimer: this is both a quick and dirty solution to the aforementioned issues ***
Before running your app in Xcode (pressing the play button), in your project directory run the following command:
ionic cordova prepare ios
This will load your changes and update your app in Xcode before running it in your emulator so you can then debug and see your edits.
Open to suggestions if anyone has a more direct solution!
Try:
cleaning the build folder in Xcode: cmd+shift+k
In the "Device" menu of Simulator, click "Erase All Content and Settings"
Quit Xcode, simulator and whatever program you are running the emulate command in
Reboot the machine

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...
I'm trying to deploy my Ionic app to an iPhone by running either of these commands:
ionic cordova run ios
ionic cordova run ios --device
The console displays the following text:
[OK] Your app has been deployed.
Did you know you can live-reload changes from your app with --livereload?
If we look at the console output everything seems to be fine, but my iPhone doesn't detect anything and the application doesn't run. I managed to get it on my phone by opening the workspace file inside the platforms/ios and running it with Xcode, but that's a pretty tedious process, and I'm sure that's not the way to go, as it doesn't support livereload.
Also, I tried to start a new project and I'm having the same issue, so I guess it's not any plugin's fault.
Thanks in advance for your answers.
When you run the app from Xcode, does Xcode give you any more error messages in its output window? This may be a signing issue.
same error here from console.
with --verbose
get this message
registerShutdownFunction.process.exit/normal shutdown
I'm building a react-native app and accidentally deleted the app from the simulator. Even after running react-native run-ios, although the simulator is starting the icon for the app is missing. How can this be brought back?
I tried searching for .app file to drag and drop into the simulator, but could not find it inside my project directory.
Just try to run the app from X-Code.
I always do react-native start and then start the app from X-Code
When I run cordova run ios --emulator the script exits successfully and tells me, that there's a file (console.log) inside platforms/ios/cordova but there's no such file although I used console.log several times in my code.
Also, Safari does not show my device in the developer menu when it's connected via USB and running the app. I used cordova run ios --device to run the app.
Am I looking in the wrong place? Does the script lie? :D
My iOS emulator is no longer opening when I run "phonegap run ios" in the terminal on Mac OS X. I receive no error messages and:
[phonegap] Platform "ios" deployed to emulator.
[phonegap] successfully installed onto emulator
While this is currently a known bug, you can run the emulate command more directly (note you need to build separately):
phonegap local build ios
/platforms/ios/cordova/emulate
You can also run the application using the same technique:
phonegap local build ios
/platforms/ios/cordova/run
NOTE: When using this method to run the app on your phone, the task might get stuck on the splash screen. To fix this, launch the Activity Monitor on your Mac and quit any processes with the name "ios-deploy". From there you can launch the application on your phone by clicking the application icon.
Or, you can even look inside the generated /platforms/ios folder and launch XCode project directly to test in an emulator or on your device. Open project and click the RUN button.
IMPORTANT: with all of the above methods, you MUST run the build command before running:
phonegap local build ios
Not really an answer, but I can say this is a known bug. Here is the bug so you can track it:
https://issues.apache.org/jira/browse/CB-5103
I only had this problem after upgrading to 3.1. I downgraded to 3.0 and it works more reliably:
npm uninstall -g phonegap
npm install -g phonegap#3.0
Also had to delete the platform/ios dir and plugins/ios.json and then run 'phonegap build ios' and 'phonegap run ios'
