XCode is not just one of many editors to edit Swift you asshole.
It is 99% of all editors used.
A few thoughts:
1) I would like to see Xcode gain a couple more literal types using the
same strategy it does for Image and Color literals
2) I would LOVE to see simple equation typesetting in Xcode
(Those two are mostly up to the Xcode team as opposed to swift, I suppose)
3) Why are we pretending like we can always edit swift in a ASCII
editor? The argument that actually using unicode would break things
doesn’t seem valid, because Swift has supported unicode since version 1,
and people have been using it since that time to name both variables and
operators. That doesn’t mean we need a super fancy editor, but I think
requiring unicode awareness is completely reasonable. If your editor from
the 1970’s breaks something, it is both your and your editor’s fault, not
the code or the library, because Swift has unicode in it’s spec.
4) I don’t think we should let the difficulty of typing certain things
stop us. It is an issue we need to consider, but it is an issue which can
be solved fairly easily with good UI design if there is a need. Sure,
different editors might solve it in different ways, but they will all solve
it if it is useful (and in a few years, we will have all settled on the
best approach). As people have mentioned, it can be difficult to type ‘{‘
on certain language layouts, so if we limited ourselves by that we couldn’t
do anything. We shouldn’t adopt a lowest common denominator approach.
5) The lack of ‘≤’ has driven me absolutely nuts since Swift 1. It
*won’t* be confusing if we let people do either ‘<=‘ or ‘≤’ (there is
research by Apple in the late 80’s that proves this). We all learned the
symbol in math class. Even non-programmers know what it means. Assigning
it any other meaning would be confusing because it’s meaning is so widely
known. Every time I bring this up, I am told to just roll my own (which I
have)… but it means that my code will now clash with everyone else’s
identical implementation (because there is only one sane way to implement
it). The fact that there are multiple identical implementations
interfering with each other (and no real way to make a significantly
different implementation) tells me it really should be part of swift
itself. Every time I bring it up, people complain about it being extended
ASCII instead of pure ASCII, and that it is hard to type on a German
keyboard (those people can either just type ‘<=‘ or use a better editor
which autocompletes ‘<=‘ to ‘≤’).
6) My recommendations for typing symbols would be:
a) Choose a subset of useful and well-known symbols instead of every
symbol
b) Allow autocomplete on those symbols by name
c) Optionally choose a little-used guardian character to start the names
of symbols (to avoid accidental autocompletion).
Thanks,
Jon

Wouldn’t it be nice to have an actual multiplication matrix broken out
into code,
instead of typing, “matrix()”? It seems to me Swift has the chance to do
that.
Also: why does "<==" still reside in code as "less than or equal to” when
there is a unicode equivalent that looks neat?
Why can’t the square of x have a superscript of 2 instead of having
“pow(x,2)?
I think this would make programming much easier to deal with.
I expound on this issue in my article:
