Xcode 8 AppStore upload (error 434)

app-store, upload, validation, xcode8

Solution

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.

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

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.

Problem

When I tried to validate an `App Store` build using `Xcode 8` I'm getting the following error: ``` ITunesSoftwareServiceAuthenticationErrorDomain 434. ``` What does this mean?
