ERROR ITMS - 90167 No. app bundles found in the package

Question

Before I start writing about the error, I\'m running on macOS Sierra and using Xcode 7.3.1.

So I\'m creating an Archive from my App, I validate the App and it passes

Answer 1

I was getting this error with Xcode 7.2.1 and Application Loader 3.4 on macOS 10.12.1.

But for some reason, it worked if I used the command-line "altool" to do the upload instead:

'/Applications/Xcode-7.2.1.app/Contents/Applications/Application Loader.app/Contents/Frameworks/ITunesSoftwareService.framework/Versions/A/Support/altool' \
  --upload-app -f your-app.ipa \
  -u your-apple-id -p your-apple-id-password \
  --output-format xml
