You can also create a new build.json file at the root of your cordova project, if you don't already have one, and add the following json data. This basically tell the build process for "ios" to use the legacy build system. It will automatically add the build flags in the build.json file to your build command e.g. cordova build ios --prod will also run as though it was typed as cordova build ios --prod --buildFlag="-UseModernBuildSystem=0".
{
"ios": {
"debug": {
"buildFlag": [
"-UseModernBuildSystem=0"
]
},
"release": {
"buildFlag": [
"-UseModernBuildSystem=0"
]
}
}
}
