Current behavior:
Can only launch one ionic 3 app at a time on ios physical device. No issues on android devices

Expected behavior:
Should be able to launch multiple ionic 3 app.

Steps to reproduce:

1. Create app1 and app2:
   ionic start app1 blank
   Integrate your new app with Cordova to target native iOS and Android? Yes

ionic start app2 blank
Integrate your new app with Cordova to target native iOS and Android? Yes

2. add ios platforms to both projects and install the apps to a physical ios device(I tested it on an iphone x):

ionic cordova run ios

When the second app opens, it might give error "Unable to load app". If it doesn't, make sure the first app is open, and launch the second app again.

3. If install the apps using xcode, xcode displays the following error message:
