As I understand, the primary issue packaging Swift for Linux is LLVM. Swift uses Apple's fork of LLVM and distributions want to compile against system LLVM and do not want two copies of LLVM slightly different. This needs to be solved on Swift side. Rust had the same problem, and until it was fixed, Rust wasn't packaged by Linux distributions either. (I know this because I helped ensuring Rust's ability to compile against system LLVM.)
