I really wish Swift closures were more uniform. I remember Alan Kay (or maybe Dan Ingalls) was famed for saying “its ok to cheat, as long as you don’t get caught” (re. Language implementation).

I really like swift, but there are times when I feel I need a magic decoder to figure out which edge cases apply. My biggest frustration is that something like this

    for view in self.subviews { view in
        ...
        return something
    }

Is very different from the naively similiar

    self.subviews.forEach { view in
        ...
        return something
    }

I just wish closures were a more first class part of the language like they were in Smalltalk. If language written in 1980 could use closures/lambdas all the way down even for things like if/else, and keep the deception pretty complete, I don’t understand why swift can’t do similiar.
