What's up with Swift 5
summary
Swift 5 promises ABI stability so apps stop bundling ~8–10 MB of Swift runtime, and it requires concrete work: implement conditional conformance and recursive associated-type constraints in the standard library, finalize the memory ownership model with the law of exclusivity, and ship a working migration path (migration assistant is open source). Ongoing evolution prioritizes string ergonomics, standard-library fixes, and leaves a full concurrency model as a future effort.
