I'm trying to create xcframework of j2objc built by make dist.
Presumerbly those .a files are compiled as fat library, but built with xCode10 due to compile errors when compile with xCode11.
My build environments are xCode11 beta 2 and MacOS 10.5 beta.
$ xcodebuild -create-xcframework -library ./lib/libjre_emul.a -library ./lib/macosx/libjre_emul.a -headers ./include/ -output lib/universal/libjre_emul.xcframework
error: binaries with multiple platforms are not supported './j2objc/dist/lib/libjre_emul.a'
