How to compile framework for Mac Catalyst on Xcode 12? - swift

Question

I have been trying to compile the aws-sdk-ios for Mac Catalyst but I wasn't successful yet. Below there is the script that I use to compile for armv7 and x86_64 (simulator).
# Build .a files
xcodebuild ARCHS="i386 x86_64" \
ONLY_ACTIVE_ARCH=NO \
-configuration Debug \
-project "${project_path}" \
-target "${project_name}" \
-sdk iphonesimulator \
SYMROOT=$(PWD)/builtFramework
xcodebuild ARCHS="armv7 arm64" \
ONLY_ACTIVE_ARCH=NO \
-configuration Release \
-project "${project_path}" \
-target "${project_name}" \
-sdk iphoneos \
SYMROOT=$(PWD)/builtFramework
This correctly compiles the project and results into these folders:
I tried to compile the project for Mac Catalyst with multiple variations of the code below (based in multiple examples on the internet):
xcodebuild ONLY_ACTIVE_ARCH=NO \
-project "${project_path}" \
-target "${project_name}" \
-destination "generic/platform=macOS,variant=Mac Catalyst,name=Any Mac"
SYMROOT=$(PWD)/builtFramework
This seems to not create any Release-maccatalyst folder or anything else, even adding these flags:
SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES SUPPORTS_MACCATALYST=YES
Or these:
ARCHS="x86_64" VALID_ARCHS="x86_64"
(Also tried with x86_64h, no luck)
With the ARCHS flags above, the compilation fails with these errors:
I am not sure what I need to do to compile the project, anyone could please help me to find the correct script to create the .framework for Catalyst?
