Xcode 9 GM - Export and Upload to App Store crashing

Question

I\'m trying to upload my app that uses ARKit (Unity build) to iTunes Connect for TestFlight distribution. While both exporting and uploading to app store processes from Xc

Answer 1

In my case, it was due to permissions issues with python.

When running xattr from terminal I had the following error:

IOError: [Errno 13] Permission denied: '/Users/cb/Library/Python/2.7/lib/python/site-packages/zc.buildout-1.5.2-py2.7.egg-info/namespace_packages.txt'

Taking a look inside the /Users/cb/Library folder I found that all of the folders were owned by cb:staff (my currently logged in user and group) but the /Users/cb/Library/Python folder was owned by root:wheel

Running the following will eliminate the error:

sudo chown -R $USER:$(id -g) /Users/$USER/Library/Python

After the sudo chown you can run xattr again to verify. There should be no errors or other output from the xattr command.
