ios - Xcode 6.4 Export Adhoc "Session has expired"

Question

I am trying to export an iPhone app using Xcode 6.4 but am receiving an error:

Your session has expired. Please log in.

When Xcode checks the developer portal for Development Teams.

I have double checked my credentials in Xcode > Preferences > Accounts and I am able to select "View Details" for the team and see Signing Identities and Provisioning Profiles as expected. I did try selecting the little refresh button in the bottom left and received the same error:

Your session has expired. Please log in.

I double checked logging into the developer portal and no problems there.

I tried restarting Xcode and was able to select my Development Team, but right as the build started to export, Xcode crashes.

I did notice that Xcode 7.1 has been released. Maybe Xcode 6.4 is no longer supported?

Edit Here's the stack trace from the crash:

Looks like Apple has some kind of technical issues today. It's not related to version of XCode. I see the same error with XCode 7.0.1 right now. Re-adding account will not help.
