ionic cordova build iOS hangs only when iphone attached to Mac

Description: Using cli 5.2.6, running Ionic v1 app - running ionic cordova build iOS hangs the app after this file is compiled ONLY if an iPhone is attached to the Mac. Disconnect the iPhone and it compiles just fine. Running cordova build iOS builds just fine even with an iPhone connected to the Mac.

<edit correction>

I suspect it “might” be related to Cordova-plugin-firebasex - this is happening with firebasex plugin versions 6x and higher. I brought this to the attention of the plugin owner/developer (Dave Allen) and he believes its a ionic cordova build wrapper issue as the issue doesn’t happen when just doing cordova build iOS.

My Environment:

Ionic:

   Ionic CLI         : 5.2.6 (/usr/local/lib/node_modules/ionic)

   Cordova Platforms : ios 5.0.1
   Cordova Plugins   : cordova-plugin-ionic-keyboard 2.1.3, (and 32 other plugins)

Utility:

   cordova-res : 0.6.0 
   native-run  : 0.2.8 

System:

   ios-deploy : 1.9.4
   ios-sim    : 8.0.2

Fix confirmed, both in my test case documented on https://github.com/dpa99c/cordova-plugin-firebasex/issues/5 and in my main project fastlane build.

Thanks!
