Unity Exception StackTrace is missing when upgrading xcode to version 9

Unity Engine

  • Unity version: 5.6.1p1
  • Bad Xcode version: 9.0 (9A235)
  • Good Xcode version: 8.3.3 (8E3004b)

I am a game programmer and I use Unity to develop our game. Before I upgrade xcode, everything is fine. Any exception thrown can be caught and logged with detailed stacktrace. It is very useful to me. But after I upgrade xcode to version 9.0, I found all the stacktrace is missed when some exception is thrown. I can only get the type and the message of the exception. It is so wired.

these are the key steps to I use to export ipa from unity:

  • export unity project to a xcode project.
  • xcodebuild archive with some necessary options to archive to file XXX.xcarchive.
  • xcodebuild -exportArchive with some necessary options to get the final ipa.

This is the good exception log(with xcode 8.3.3):
type: System.Reflection.TargetException

This is the bad one(with xcode 9.0):
type: System.Reflection.TargetException
msg: Non-static field requires a target
target:

It is so wired. Is there anybody know what changes in xcode 9?
