Testing new iOS backend

Hi there!

I’ve just tried to build the game using the tips you gave me. It looked promising but I’ve found plenty of issues. I’m commenting them here but I think we should create a new thread for iOS

First of all, I noticed the whole graalvm thing is for arm64 only like the binary downloaded from liberica-nik (file build/libjglios/third_party/graalvm-host/liberica-nik-23.1.3-macos-aarch64/lib/svm/bin/native-image: Mach-O 64-bit arm64 executable, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|PIE> ) and the releases at Releases · NostrGameEngine/ios-graal-jdk-21 · GitHub are only arm64 also so as I don’t own a arm based mac but an intel hackintosh I ended up running the build from github actions (buildIosSimulatorApp target). So it would be great if possible to add also x86_64 arch

About the build itself, I’m getting lots of linker errors:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Apart from the issues I’ve found so far, I have other question, how to add external libraries? For example what if I want to add facebook login or google ads? I also have a custom iOS compilation of libbulletjme for minie in xcframework format, how could I include it to the graalvm library?

Thanks
