Xcode 8 AppStore upload (error 434)

Question

When I tried to validate an App Store build using Xcode 8 I'm getting the following error:

ITunesSoftwareServiceAuthenticationErrorDomain 434.

What does this mean?

Answer 1

I received the same error on multiple attempts. I made some changes (to provisioning profiles etc.) and then validation worked fine a couple of times. But then the error message came back for no apparent reason. Seems like a bug on Apple's side.

Since then I switched to use Application Loader, and with that workflow I have not encountered any problems. Here's how.

1. In the Xcode Organizer, I do not use "Validate...", but instead "Export..." to save the my_product.ipa file.

2. Then open Apple's Application Loader (Xcode menu > Open Developer Tool > Application Loader), and with that I upload the my_product.ipa to iTunes Connect.

This process has seemed reliable to me.

Answer 2

Firstly, I received the same error on multiple times. Change some codes, finally release that :

Solution:

unchecked "include bitcode" , then validate (in my case it was successful)

After

Validate with checked "include bitcode"

P.S : Next time, I used XCODE Application Loader. It will be ok for deploy your application.

For what it's worth, this appears to be intermittent. I just received the error and literally did a retry without doing anything else and it worked.
