After upgrading to xcode 8.3 I encounter this error trying to build for iOS:
xcrun: error: unable to find utility “PackageApplication”, not a developer tool or in PATH
Error: Error code 72 for command: xcrun with args: -sdk,iphoneos,PackageApplication,-v,/Users/brett/Dec/myapp/platforms/ios/build/device/MyApp.app,-o,/Users/brett/Dev/myapp/platforms/ios/build/device/MyApp.ipa
This was deprecated in 8.3, I’m unsure if this a Cordova issue as it appears modifications to /platforms/ios/cordova/lib/build.js would be required to fix this - I’m not certain if this is an Ionic wrapper for Cordova?
In either case my current workaround is to downgrade xcode, but this isn’t ideal…
