<pre><code class="swift">

<p>This is embarrassing and ugly.</p>
<p>I’d rewrite this to:</p>
<pre><code class="swift">class SomeName {
private var _variableName: String
private var _optionalName: SomeType?
func notAnInitializer() {
self._variableName = "ugly code"
if self._optionalName == nil {
self._optionalName = SomeType()

self._optionalName?.doSomething()

<p>My personal preference is to leave an empty line at the top (for readability from my personal prospective) and I do prefer <code>self.</code> for clarity what I’m accessing and from where it comes from.</p>

I’d love to see something like this happen to Xcode. I’m curious if
we could write an extension for Xcode 8 to refactor code to at
least some of the conventions.<span class="Apple-converted-space"> </span></p>

<div class="">I don't believe these rules have a place in the API
guidelines</div>

<div><br class=""></div>
<div>No, not API guidelines per se, but code-style guidelines. I
think for the sake of a more unified code-style, given the team's
strong position on not allowing any language dialects, I'd suggest
something like this being put together. (Yes, I understand that a
language dialect is something different, but the point is that
there is a strong feeling about a unified languaged.)</div>
<div><br class=""></div>
<div>When you look at various code in ObjC (StackOverfow, Github),
the code styles vary incredibly and it's a mess, looking at some
code gives you a headache because it is obvious that the person who
wrote it came from C# environment. Yes, it's up to the project's
team to decide on some minor things (e.g. whether to go by the
80-char per line limit, use explicit self, etc.), but the major
things, such as placement of brackets, colons, spaces between them,
etc. should be standardized.</div>
<div><br class=""></div>
<div>Because currently, as Ben has pointed out, the standard
library has a different code-style than the Swift Programming
Language or the WWDC presentation and it will diversify over the
time.</div>
<div><br class=""></div>
<div>I kind of really like what Microsoft has done with C# - their
coding conventions are out there, clear and precise.</div>

<div>You may ask why would one care? Aside from me being kind of a
nitpicker in this area, this is nice when you share code between
projects - you have a single code-style even if you share the
code.</div>

be constructed for consumption. Style rules are best
addressed by in-house style guides. I've personally adopted
left-magnetic colons. This follows the Docs team style. The stdlib
folk appear to use floating colons for protocol conformance.</div>
