Bitrise, Xcode9 (beta6): bitcode bundle could not be generated

Question

One of the frameworks I use fails to get built with Bitrise with Xcode9beta stack. I must point out that this is Bitrise-specific issue. Or either, Bitrise/Eureka issue. Eureka is a particular instance of third-party framework.

Project is built well on the local machine, no bitcode-related issues whatsoever. But whenever I run CI, I get that typical log:

❌  ld: bitcode bundle could not be generated because '.../Frameworks/Eureka.framework/Eureka' was built without full bitcode. All frameworks and dylibs for bitcode must be generated from Xcode Archive or Install build file '.../Frameworks/Eureka.framework/Eureka' for architecture armv7

❌  clang: error: linker command failed with exit code 1 (use -v to see invocation)

I followed these guidelines: iOS library to BitCode

Flag is set.

I have also tried similar settings for head project/target, to no avail.

Any suggestions?

Seems to be a dependency (version) issue:

... was built without full bitcode. All frameworks and dylibs for bitcode must be generated ...

Might be enough to just upgrade the eureka dependency.

Another thing is that Xcode 9 (GM) is also available now, that alone might help.

Edit: a third option; you might have to disable Bitcode in the Xcode / xcodebuild command, as the default changed in Xcode 9 for some configs. See eg https://discuss.bitrise.io/t/xcode-archive-significantly-slower-on-xcode-9-0-x-stack-compared-to-xcode-8-3-x-stack/2708/2?u=viktorbenei

Without more log / info unfortunately it's quite hard to say with certainty.

If neither would help, you can also create an issue report at https://discuss.bitrise.io/c/issues/build-issues and the bitrise team will look into it ;)
