xcodebuild archive fails for RxCocoa using SPM

[hungrxyz]

Short description of the issue:

Archiving a framework which is using RxCocoa as a Swift package dependency fails using xcodebuild.

Expected outcome:

Archive succeeds.

What actually happens:

Here's my command to archive the framework:

xcodebuild archive \
    -project Project.xcodeproj \
    -scheme Scheme \
    -destination "generic/platform=iOS" \
    -configuration Release \
    -archivePath "archives/Release-iOS" \
    SKIP_INSTALL=NO \
    BUILD_LIBRARY_FOR_DISTRIBUTION=YES \

And here's the command line output:

** ARCHIVE FAILED **

The following build commands failed:

(this is so we can understand your level of knowledge
and formulate the response in an appropriate manner)

try it:

xcodebuild archive \
    -project Project.xcodeproj \
    -scheme Scheme \
    -destination "generic/platform=iOS" \
    -configuration Release \
    -archivePath "archives/Release-iOS" \
    SKIP_INSTALL=NO \
    BUILD_LIBRARY_FOR_DISTRIBUTION=YES \
OTHER_SWIFT_FLAGS="-no-verify-emitted-module-interface"

try it:

xcodebuild archive \
    -project Project.xcodeproj \
    -scheme Scheme \
    -destination "generic/platform=iOS" \
    -configuration Release \
    -archivePath "archives/Release-iOS" \
    SKIP_INSTALL=NO \
    BUILD_LIBRARY_FOR_DISTRIBUTION=YES \
OTHER_SWIFT_FLAGS="-no-verify-emitted-module-interface"

I think I tried that already and it didn't help but I'll try again to make sure and report back this week hopefully.

I'm also not sure if it works well.
Maybe it will generate another error.

Please provide a reproducible project to test, and also try the latest release :)
Thanks.
