You are misunderstanding - this isn't about which is better. Almost all new application code will be written in Swif, but swift doesn't bridge between C and the Swift/obj-c runtime, so Objective-C will continue to be required for writing the glue layer.

Yes it does.

Additionally, this is just version 1.0. So nothing rules out that if Apple sees the language being widely adopted, other improvements in the FFI area aren't made.

I stand corrected, and your argument holds, however there is a great deal of objective-c code out there, so it will take a long time to go away.
