I highly doubt it will happen. Apple wants to avoid runtime compilation (which this would be an LLVM runtime deal I assume) on iOS from what I gather about their no-VM-on-iOS policy. Not sure if Apple embeds typing metadata in libraries. If so, I don't see why type checking is impossible, at least for exposed (i.e. @objc) stuff.
