Not able to emulate ios with Cordova

问题

I'm going through the beginner series for a Cordova application. I installed XCode and created a new Cordova project. That being said, when I run cordova emulate ios, I get the following error:

No target specified for emulator. Deploying to iPhone-X, 12.1 simulator
/Users/osx/Code/cordova-poc/platforms/ios/build/emulator/HelloCordova.app/Info.plist file not found.

If I run cordova build ios and run the code in XCode, then I can see that Xcode opens up the emulator where I can see my changes. This is, obviously, too slow.

回答1:

I suspect that you're running XCode 10. XCode 10 has a new build system which is not yet supported by Cordova.

You should be able to work around this by running the following:

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

回答2:

As stated

Xcode 10 uses a new build system by default (previously available on an opt-in basis in Xcode 9). The cordova-ios project structure is not compatible with this new build system and results in failures. Source

1 CLI WORKAROUND

# Cordova CLI
cordova run ios --buildFlag='-UseModernBuildSystem=0'
cordova build ios --buildFlag='-UseModernBuildSystem=0'

# Ionic CLI
ionic cordova run ios -- --buildFlag="-UseModernBuildSystem=0"
ionic cordova build ios -- --buildFlag="-UseModernBuildSystem=0"

2 CONFIG FILE WORKAROUND

"buildFlag": [
  "-UseModernBuildSystem=0"
]

In your build.json config file.

3 XCODE WORKAROUND Thanks to @kitolog for the screens.
