Blank app fails debug build - /Info.plist file not found

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

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

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

This worked for me:

cd platforms/ios/cordova && npm install ios-sim@latest
