I've uploaded a pure-Swift 2 binary to iTunes Connect, with hopes of distributing via Test Flight.
This should be possible, according to iTunes Connect itself:

Unfortunately, my binaries are met with an "Invalid Binary" error:

Obviously, I've tried this a few times. What hasn't worked:
- Setting
Embedded Content Contains Swift CodetoYES - Setting
Embedded Content Contains Swift CodetoNO - Setting
Enable BitcodetoYES(can't find why I tried this) - Setting
Enable BitcodetoNO
The error I'm receiving via email is:

Which seems to suggest that the first screenshot, taken from iTunes Connect, is wrong. Have I gone crazy? (There are those who think we all have.)
Update: It would appear that some people can upload their iOS 9 betas. After running all of these attempts again, I am not one of those people.
Update: This is only happening with one of my apps. The only source or dependency difference between the two is that the failing app uses the Parse SDK Cocoapod.
