In a larger context I resorted back to creating a blank project and running my build commands. Same error:

ionic start myApp blank
cd myApp
ionic cordova run ios --debug --target="iPhone-8"  --consolelogs



ionic-app-scripts build --target cordova --platform ios

        Re-running this command with the --verbose flag may provide more 
        information.

ionic --version

cordova --version

XCode Version 10.0 (10A255) + build tools
macOS 10.13.6 - High Sierra. Mojave on a different machine fails the same.

The paths are adjusted if anyone wonders...

-------------- FIX --------------

Together with @DaveAlden's answer this is how I got it back up to do livereload without the bugs:

ionic cordova platform remove ios sudo npm install -g ionic@3.20.0 ionic cordova platform add ios open platform/ios/MyApp.xcworkspace

Follow instructions to fall back to legacy build system as on https://github.com/apache/cordova-ios/issues/407

Run my build script, without the --buildFlag='-UseModernBuildSystem=0'

This problem is caused because Xcode 10 contains a new build system which is currently not compatible with cordova-ios@4 - see here.

The solution for now is to run Cordova with the --buildFlag='-UseModernBuildSystem=0' option to instruct Xcode to use the old build system, e.g.:

 cordova run ios --debug --target "iPhone-8" --buildFlag='-UseModernBuildSystem=0'

Update: For my own convenience, I've wrapped this in a shell script:

#!/bin/bash
# Adds build flag to make cordova-ios@4 work with Xcode 10
cordova "$@" --buildFlag='-UseModernBuildSystem=0'

I saved this in a file called cordova-xcode10, made sure it's in the path and made it executable (chmod a+x cordova-xcode10), then I can just do:

cordova-xcode10 run ios --target "iPhone-8"

and it will work with Xcode 10

    Thanks. Yes, I confirm. Just found that 1h ago. However, now my livereload / consolelog is disabled or does not work, even after setting to legacy in xcode. – El Dude Oct 02 '18 at 05:40
  • See my comment above how to re-enable live reload. The `buildFlag` seems to override this... – El Dude Oct 02 '18 at 16:08

This problem is caused because of Xcode 10. I resolved this issue by two ways.

  1. ionic cordova build ios -- --buildFlag="-UseModernBuildSystem=0"

  2. Create a build.json file on root of project.

In build.json write below code.

{
    "ios": {
        "debug": {
            "buildFlag": ["-UseModernBuildSystem=0"]
        },
        "release": {
            "buildFlag": ["-UseModernBuildSystem=0"]
        }
    }
}

After that you can run these commands without any error.

  • ionic cordova build ios
  • ionic cordova run ios
  • ionic cordova run ios --target="iPhone-6s" -l

    Upvoting this answer in preference to the accepted answer, as it explains how to add the flag to your build config so that it doesn't need to be added via the command-line on each invocation. Much better than requiring each developer to set up a wrapper script as suggested in the accepted answer. – HappyDog Mar 08 '19 at 14:05

This worked for me

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

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

Then run ionic cordova run -l

Update

I just found out that Cordova IOS 5.0.0 was released. https://cordova.apache.org/announcements/2019/02/09/cordova-ios-release-5.0.0.html

only add this flag in you command 

cordova run ios --device --buildFlag='-UseModernBuildSystem=0' --verbose

work fine for me
