iTunes Connect: There was an error importing this build

Question

I'm working on an iOS app that last week had a build successfully uploaded to iTunes Connect and then distributed for testing via TestFlight.

This week, I updated to Xcode 7.3 and now when I update the same project (with changes just for Swift 2.2 compatibility and some other bug fixes I did), I am able to archive and submit the build through Xcode, but then instead of processing and receiving an email that the build is ready to test, the build shows up in iTunes Connect like this, with the displayed error message. I don't receive any email or other error message about what could be wrong:

I haven't found any other solutions searching online about this issue. I've gotten in contact with Apple and the issue has been escalated but haven't heard back yet.

Update - Apple has escalated to engineering, awaiting response.

Update 2 - Apple replied that this is a known issue with Xcode 7.3 and Bitcode, see answer below for solution.

Answer 1

Apple has replied that this is a known issue with Xcode 7.3 and Bitcode. So, I disabled including Bitcode uploading with the binary and it successfully processed!:

You do not need to disable it for the entire project, but it works that way too (tested with both project Bitcode enabled/disabled with Bitcode upload inclusion disabled).

Edit: Builds as of 4/7/16 are now successfully uploading and processing with Bitcode.

Answer 2

I received this error for the first time yesterday.
I did not have bitcode turned on.
I had no other message beyond the iTunes "There was an error importing this build".

Today I bumped up the version number and resubmitted and it worked.

Answer 3

Random problems like this happen to me sometimes and instead of uploading from the Xcode organizer what I do is use the organizer to export a build and then use Application Loader (available from the Xcode menu -> Open Developer Tool) to actually upload it. Sometimes it helps and sometimes it doesn't, but it's worth a try.

Answer 4

Just in case if aforementioned solution not worked for you try the following. Cause none of the listed solution worked for me.

1. Check for the Xcode Version. It should not be a BETA release.
2. If still getting issue the upload it using Application Loader. Don't use CMD + Space to launch Application Loader. It might open old or different version Application Loader. Which leads you to ambiguous bugs. Launch from the Xcode menu Xcode -> Open developer tool -> Application Loader solves the problem. Please make sure you do it from the version of the Xcode that you used to build your app.

Cheers!! :)

Give it some time(an hour or two). It auto-solves.

May or may not work be a good advice, but this is what worked for me.
