Unable to build scheme RxAtomic

[acidburns388]

Hi, I've download xCode 12 and I'm trying to update Carthage.
I'm using command "carthage update --platform iOS --no-use-binaries" and I get this error:

*** Building scheme "RxAtomic" in Rx.xcworkspace
Build Failed
Task failed with exit code 1:
/usr/bin/xcrun lipo -create /Users/intellithings/Library/Caches/org.carthage.CarthageKit/DerivedData/12.0.1_12A7300/RxSwift/4.5.0/Build/Intermediates.noindex/ArchiveIntermediates/RxAtomic/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/RxAtomic.framework/RxAtomic /Users/intellithings/Library/Caches/org.carthage.CarthageKit/DerivedData/12.0.1_12A7300/RxSwift/4.5.0/Build/Products/Release-iphonesimulator/RxAtomic.framework/RxAtomic -output /Users/intellithings/roomme-iosApp/Carthage/Build/iOS/RxAtomic.framework/RxAtomic

This usually indicates that project itself failed to compile. Please check the xcodebuild log for more details: /var/folders/wh/dbpm0qy14w3gd4l3q35_l1h80000gn/T/carthage-xcodebuild.4td519.log

Any help will be appreciated.
Thanks,
Shahar

This is RxAtomic not building, which is not a dependency of RxLifx-Swift, so not really my area of expertise, or something I can easily reproduce.

If you want to understand this better, I would suggest to run /usr/bin/xcrun lipo -create /Users/intellithings/Library/Caches/org.carthage.CarthageKit/DerivedData/12.0.1_12A7300/RxSwift/4.5.0/Build/Intermediates.noindex/ArchiveIntermediates/RxAtomic/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/RxAtomic.framework/RxAtomic /Users/intellithings/Library/Caches/org.carthage.CarthageKit/DerivedData/12.0.1_12A7300/RxSwift/4.5.0/Build/Products/Release-iphonesimulator/RxAtomic.framework/RxAtomic -output /Users/intellithings/roomme-iosApp/Carthage/Build/iOS/RxAtomic.framework/RxAtomic to see the actual output of lipo.

You are probably running against this issue:
