Fresh Ionic Fails to Emulate iOS 12 - Info.plist file not found



Yesterday my mac got an update for iOS 12. I created a fresh ionic project with ionic start, builded successfully. When I try to emulate I got the error below:

[cordova] No target specified for emulator. Deploying to iPhone-XS-Max, 12.0 simulator
[cordova] /Applications/MAMP/htdocs/start/start/platforms/ios/build/emulator/ file not found.
[ERROR] An error occurred while running subprocess cordova.

This is a cordova issue. Follow this thread


Thank you. Below code fixed the error for me.

ionic cordova emulate ios -- --buildFlag="-UseModernBuildSystem=0"


It works here! Thanks!


Its works for me. thanks :slight_smile:


funciono !!! muchas gracias.


Its working fine but , every time needs to run same command?

I cant get my ionic app to open in iOS emulator

I just run e.g.

npm run emulate-live

This is my scripts block in package.json file:

"scripts": {
    "clean": "ionic-app-scripts clean",
    "build": "ionic-app-scripts build --prod",
    "lint": "ionic-app-scripts lint",
    "emulate-live": "ionic cordova emulate ios -lc --debug --target=\"iPhone-X\" -- --buildFlag=\"-UseModernBuildSystem=0\"",
    "emulate-live-iPhone-8-Plus": "ionic cordova emulate ios -lc --target=\"iPhone-8-Plus\" -- --buildFlag=\"-UseModernBuildSystem=0\"",
    "emulate": "ionic cordova emulate ios --target=\"iPhone-X\" -- --buildFlag=\"-UseModernBuildSystem=0\"",
    "build-prod": "ionic cordova build ios --prod --release -- --buildFlag=\"-UseModernBuildSystem=0\"",
    "device": "ionic cordova run ios -- --buildFlag=\"-UseModernBuildSystem=0\""


Open your workspace file, then File --> WorkSpace Settings

In shared Workspace settings, choose Build System: Legacy Build System.

Then run ionic cordova run -l
