iOS Build error to browser & Simulator

After following Microsofts tutorial ( on how to setup remotebuild and such on Mac, and proceeding to launch my app just to the brower. I receive a white screen and in chromes console it says content.ionScrollStart.takeuntil is not a function which looks to be thrown from within ion-inputs compiled js file.

I am at a lose here and haven’t been able to pinpoint the exact problem. Also attempting to launch to a simulator generates a cordova-build error : Error: There are multiple *.xcodeproj dirs

I’m running the latest High Sierra update with xcode 9.4

Any help would be appreciated.
