Perhaps this has been discussed a lot already, but I'm a bit lost as to the current state of cross-compiling Swift source code from x86_64 Linux to ARM Linux. Given the documentation for cross-compiling for Android, it seems that there is some cross-compiling support, but I'm not sure how I should go about making it not Android specific.
To be more concrete, I would like to experiment with Swift for the FIRST Robotics Competition, which uses ARM Cortex A9, running Real-Time Linux. For now, a reasonable intermediate goal seems like figuring out cross-compiling to a Raspberry Pi, which has already seen some attention from the Swift community.
So, it would be awesome if anyone can point me in the right direction!
