What did you do?

Create a xcframework using the following gomobile bind command:

gomobile bind \
	-ldflags "-X client.Version=$WARP_VERSION" \
	-target ios,iossimulator,macos,maccatalyst -iosversion 16.0 \
	-bundleid com.bringyour \
	-trimpath \
	-gcflags "-dwarf=true" \
	-ldflags "-X client.Version=$WARP_VERSION -compressdwarf=false -B gobuildid" \
	-o "build/$BUILD_DIR/URnetworkSdk.xcframework" \
	github.com/urnetwork/sdk;

The command ends with an error:

gomobile: maccatalyst/amd64: go build -gcflags -dwarf=true -ldflags -X client.Version=2024.12.3-outerwerld -compressdwarf=false -B gobuildid -trimpath -buildmode=c-archive -o /var/folders/r3/v_3z60rx2cxg0s1r9tl9fbmw0000gn/T/gomobile-work-3462168386/URnetworkSdk-maccatalyst-amd64.a ./gobind failed: exit status 1

What did you expect to see?

The maccatalyst libraries should be included in the built xcframework without error.
