"Invalid Swift Support" after uploading IPA via Application Loader

[Former user]

I have received an email from Apple after uploading the resigned IPA using Application Loader.

Dear developer,

We have discovered one or more issues with your recent delivery for "EdgevisTest". To process your delivery, the following issues must be corrected:

Invalid Swift Support - The file libswiftAVFoundation.dylib doesn’t have the correct code signature. Make sure you’re using the correct signature, rebuild your app using the current public (GM) version of Xcode, and resubmit it. Don’t just modify the code signature of libswiftAVFoundation.dylib.

Once these issues have been corrected, you can then redeliver the corrected binary.

Regards,

The App Store team

I have created an account to track this issue, if you could reply to me using that it would be greatly appreciated.

You need to use xcode

So I cannot resign my already created IPA and upload through Application Loader? How am I meant to upload an IPA through Xcode when it's usually an .xarchive file that is used? @xgiovio
