The Swift compiler and runtime know how the Objective-C runtime works, so so 
Swift can treat Obj-C classes and objects as first-class citizens.

Sure, since you can create Obj-C compatible classes in Swift simply by using 
the @objc annotation.

However, rewriting a framework from scratch is always a perilous activity and 
not something to be done lightly. This may happen over time, but I wouldn't 
expect wholesale rewrites in the near future.
