> Please elaborate.

Ideally Swift would have been something with compile speed of Delphi, its RAD capabilities, strong typing with a good enough type system to support the transparent migration path from Objective-C, and that was it.

Instead we have quite a few type systems ideas going back and forth, with some hard changes across language versions, as if playing with Haskell type system, and GHC feature flags.

Some users request those features, most of them come from team themselves roadmap, regarding what cool features to add next.

Then as politics get into the game, naturally the process of what features land into the stable implementation, and what fail by the wayside depends pretty much how they get pushed into adoption.
