#Mac emulator ubuntu code

Given that the OP sets up his Ubuntu instance with right native Swift tools (which I assume he has since he has been developing for awhile), he should be able to tell the instance to compile this, link that, put the executable here, using Darwin command line invocations. Canonical has this Multipass product that provides Darwin command line tools to interact with an Ubuntu instance running on a hypervisor.

He wants to write and debug the code using Xcode, then compile and try out on Ubuntu. The OP wants to do this from within Xcode. It may take some time to get this all setup, but you should have the quick iteration you're looking for after that. You can specify the path to the Swift stdlib and core libraries separately with the -resource-dir flag not used in that documentation, ie /path/to/linux-swiftc/usr/lib/swift.-sdk to the C headers and libraries for linux, ie the directory containing /usr/include and /usr/lib/ with those files.-tools-directory should point to the cross-compilation toolchain, ie the C compiler and linker.Take a look at the flags used to cross-compile for Android: Once you have those, you simply pass the right flags with those cross-compilation paths and some flags to the Swift compiler, as every Swift compiler is a cross-compiler just like clang, and you should be able to build for linux on macOS. You will need a C cross-compilation toolchain for linux and the Swift stdlib and core libraries for linux, which you can just get from the official Swift toolchain for linux. It should be possible to cross-compile from macOS to linux, just as others have from macOS to Android.
