Honestly? Who cares? This doesn’t seem like a reasonable conversation to have,
especially 1.5 years into Swift’s existence.
Having done a lot of work in Objective C (C-style braces), Ruby (newline, end),
and CoffeeScript (significant whitespace), I couldn’t be less bothered with
Swift’s choice of curly braces.
To me, the problem with C-style syntax are things like unnecessary parentheses
and semicolons. Swift has neither of those. Comparing {} and Ruby style, I
could go either way, it doesn’t really matter. Ruby is hardly less characters,
just different and less symbols. Also has advantage that {} in blocks is
separate from scoping. OTOH, symbolic {} is easier to discern and very clearly
shows scopes.
Significant whitespace is very neat, but many a times I was confused by it, and
made a mistake, or was close to making a mistake, because scopes just weren’t
clearly defined enough. I like it, but I can definitely see downsides.
