Issue Description

Although I am using Xcode 8, I got these warnings/errors after Archive Succeeded:

You're using Xcode 7, the `provisioning_profile_path` value will be ignored
Please follow the Code Signing Guide: https://codesigning.guide (for match) or https://docs.fastlane.tools/codesigning/GettingStarted/

and then I got stuck at xcrun

/usr/bin/xcrun /usr/local/lib/ruby/gems/2.3.0/gems/gym-1.10.0/lib/assets/wrap_xcodebuild/xcbuild-safe.sh -exportArchive -exportOptionsPlist '/var/folders/77/zxlvnwsj3dv3nc6kt_szls2w0000gn/T/gym_config20161003-2651-1jka4zc.plist' -archivePath /Users/archy/Library/Developer/Xcode/Archives/2016-10-03/LittleDragonPoC\ 2016-10-03\ 11.30.20.xcarchive -exportPath '/var/folders/77/zxlvnwsj3dv3nc6kt_szls2w0000gn/T/gym_output20161003-2651-qfr7ei'

more info

My iOS project 1. contains a custom nested framework (there are many custom frameworks inside one custom framework that the app uses) 2. is generated by Unity (the app project is exported by Unity, and we just do some code injection to get swift to take control and imported our custom nested framework to it). Before updating my xcode to xcode 8 I am able to build it and put it up on testflight just fine in xcode (after some tinkering). But after updating it to xcode 8 I get this error that I have never encountered in my life before (despite all these build errors I have encountered).

ERROR ITMS-90171: "Invalid Bundle Structure - The binary file 'MyApp.app/libswiftRemoteMirror.dylib' is not permitted. Your app can't contain standalone executables or libraries, other than the CFBundleExecutable of supported bundles. Refer to the Bundle Programming Guide at https://developer.apple.com/go/?id=bundle-structure for information on the iOS app bundle structure." 

It complains about a file named libswiftRemoteMirror.dylib. And it exists in all my frameworks and the app.

After googling I found this SO post. So I decided to give gym a try to see if it can build it without the annoying libswiftRemoteMirror.dylib.
