I've updated the Xcode (to version 8.3) today and now all my Jenkins iOS builds are failing.
This is the error:
xcrun: error: unable to find utility "PackageApplication", not a developer tool or in PATH
It looks like PackageApplication is removed from Xcode 8.3.
In Xcode 8.2 there was a warning: PackageApplication is deprecated, use `xcodebuild -exportArchive` instead.
Xcode Plugin should change the way it builds IPA file.
