Dear Developer,

We identified one or more issues with a recent delivery for your app, ***. Please correct the following issues, then upload again.

ITMS-90562: Invalid Bundle - One or more dynamic libraries that are referenced by your app are not present in the dylib search path.

ITMS-90562: Invalid Bundle - There's an issue with the app's bitcode compilation. Rebuild the app using the current public (GM) version of Xcode and upload it again.

ITMS-90562: Invalid Bundle - The app submission can not be successfully recompiled from bitcode due to missing symbols during linking.

@tomasgreen I will look into this, could you confirm your app is deploying arm64 flavor only? Your report sounds like a regression in 1.18.0, could you confirm bitcode is ok with the earlier SDK version?

Yes, I’m targeting arm64 only.

One of our projects has been a little out of date with it’s pod-dependencies. Today we upgraded from 1.14.0 to 1.18.0. This led to the conclusion that it was the most recent version that had the problem. After trying a number of different versions it turns out that the framework hasn’t been compatible with bitcode since 1.14.0.

P.S
The problem might shed some light on the issues of converting the library to an xcframework. :-)

@tomasgreen Speech SDK 1.19.0 has been released which do not have weak link dependency anymore to Gstreamer which was causing the bitcode failures. Let us know if there are any problems.
