I use ionic3 and cordova@8.1.2. Recently my Xcode update to 11.1 and error occured [Cannot read property 'toLowerCase' of undefined].I tried this way: change:

if (device.name === deviceType.name.replace(/\-inch/g, ' inch') &&
    device.availability.toLowerCase().indexOf('unavailable') < 0) {
    availAcc.push(device);
 }

to:

if (device.name === deviceType.name.replace(/\-inch/g, ' inch')) {
if ((device.availability && device.availability.toLowerCase().indexOf('unavailable') < 0)
|| device.isAvailable == 'YES') {
// XCode 10 and lower
availAcc.push(device);
}
}

Then error occurred in

Cannot read property 'name' of undefined

I cannot find where is this 'name'.

Remove platform ios and again add platform ios.
It's working for myself.

cordova platform rm ios
cordova platform add ios

My cordova version is 8.1.2. I encountered the same problem recently on ios.Please check your Android or Ios version and make it to latest if you're using older version of it. You don't need to add/modify any code to list-emulator-build file(cordova/lib/list-emulator-build). It'll be certainly working. latest version of ios is ios(5.0.1).
