Swift Pills #1
summary
Claim: implement a small Swift utility that removes the common weak‑self boilerplate by defining an empty protocol, extending it with methods that capture self weakly and return a strongified closure, and providing generic closure bridging for handlers with arguments. The code is plain Swift: protocol + extension + functions that return () -> Void or (A) -> Void, it compiles and runs, and it noticeably reduces callback boilerplate by replacing the manual weak‑strong dance.
