same Issue any resolution? Ionic cordova run ios works however to build in simulator but wont allow use in xcode to run simulator or to build on a phone

[piyushmanurkar]

I tried _ionic cordova build ios_ and successfully run in simulator with downgrade node version to
Node : v6.11.3
But issue is same with
Node : v8.11.1

Try to reboot your mac

After adding iOS platform, running the following fixed this issues for me:

ionic cordova prepare ios

[piyushmanurkar]

There is not a permanent solution for this. I fixed this by hit and try of diff-2 node versions.
