I've inherited a project that builds with Carthage. Using Xcode 12, I was faced with this error:
fatal error: /Applications/Xcode_12.3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: /Users/runner/Library/Caches/org.carthage.CarthageKit/DerivedData/12.3_12C33/AEXML/4.6.0/Build/Intermediates.noindex/ArchiveIntermediates/AEXML iOS/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/AEXML.framework/AEXML and /Users/runner/Library/Caches/org.carthage.CarthageKit/DerivedData/12.3_12C33/AEXML/4.6.0/Build/Products/Release-iphonesimulator/AEXML.framework/AEXML have the same architectures (arm64) and can't be in the same fat output file
Building universal frameworks with common architectures is not possible. The device and simulator slices for "AEXML" both build for: arm64 Rebuild with --use-xcframeworks to create an xcframework bundle instead.
Quick Google search brought me to this which works for my local machine.
Using AppCenter for the first time, I created a Pre-Build script with the following:
#!/usr/bin/env bash
# Pre-build
# See: https://docs.microsoft.com/en-us/appcenter/build/custom/scripts/#pre-build
echo "Pre-build has started."
sh ./carthage.sh update --use-submodules
echo "Pre-build has ended."
I assume Carthage should be used to build this? I get the error in AppCenter:

How to build in AppCenter?
