<p>The idea is in general the same as I showed it, my version might be really overcomplicated, but you’ve got the point there and that’s what we want for everyone. The multi-lined string (if it ever makes it) should be intuitive (and swifty).</p>
<p>One argument for using <code>"</code> is the similarity to the string literel we’re already familiar with. If you decide to split your long string literal into multilines, it shouldn’t force you to rewrite the outer characters. Ideally you should be able to simple hitting enter a couple of times and thats it (in that case your string does not need space characters). </p>
<pre><code class="swift">let string1 = "<tag_1><tag_2>content</tag_2></tag_1>"
let string2 = "<tag_1>
<tag_2>content</tag_2>
</tag_1>"
</code></pre>
<p>And we just need to come up with precision characters that will suite everyone.</p>
<pre><code class="swift">let string = "my [right_pricision_character]
[left_pricision_character]multiline [right_pricision_character]
[left_pricision_character]string"
</code></pre>
<p>Just replace <code>[left_pricision_character]</code> and <code>[right_pricision_character]</code> with something more _swifty_.

<p class="gmail_msg">I don’t really think this is about how to
indicate a multi-lined string, where the string starts and ends
with something like <code class="gmail_msg">"</code>, <code class="gmail_msg">'</code> or <code class="gmail_msg">"""</code> is
trivial to me. It’s just a decision to make. However the main
debate I see with that topic is the ambiguity from the readers
perspective.</p>
<p class="gmail_msg">In your example I assume you want a result to
match this: “my multiline string”, but what if you need precision?
Should we really fallback to single line string then? What if you
want to print some XML file with all it’s indent calculated with
whitespaces rather than tabs? The multiline version like that won’t
work, and if your string is huge you’ll end up at a place where we
already are. This doesn’t solve the main then because we could
otherwise simply allow this today:</p>
<pre class="gmail_msg"><code class="m_7291890166052924657swift gmail_msg">let string = "my
multiline
string"
</code></pre>
<p class="gmail_msg">I’m only speaking for my personal preference,
others might see it completely different. However I’m totally sure
multiline strings solve more than simply being able to write them
so that the compiler is satisfied.</p>
<p class="gmail_msg">As a compromise for everyone we possibly could
come up with a way which serves both, simplicity and precision.</p>
<p class="gmail_msg">For the next bikeshedding example I’m going to
use <code class="gmail_msg">'</code> for multi-lined strings:</p>
<pre class="gmail_msg"><code class="m_7291890166052924657swift gmail_msg">// Simplicity which supports indent but at a cost of no
// leading or trailing space characters
let string1 = 'my
multiline
string'
print(string1) // prints "mymultilinestring"
let string2 = 'my \
multiline \
string'
// Trailing precision
print(string2) // prints "my multiline string"
let string3 = 'my
' multiline
' string'
// Leading precision
print(string3) // prints "my multiline string"
let string4 = 'my \
' multiline \
' string'
// Leading and trailing precision
print(string4) // prints "my multiline string" (Note: 2x two whitespaces)
let string5 = 'my\
'multiline\
'string'
// Leading and trailing precision
// Provide a fix-it to remove some `\` and `'` characters
// because it equals `string1`
print(string5) // prints "mymultilinestring"
let string6 = 'my \
'multiline \
'string'
// Leading and trailing precision
// Provide a fix-it to remove some `'` characters
// because it equals `string2`
print(string6) // prints "my multiline string"
let string7 = 'my\
' multiline\
' string'
// Leading and trailing precision
// Provide a fix-it to remove some `\` characters
// because it equals `string3`
print(string7) // prints "my multiline string"
</code></pre>
<p class="gmail_msg">Comments should be only allowed after the
escaping character. <code class="gmail_msg">string1</code> can only
have comments after the last line of that string.</p>
<p class="gmail_msg">I think a model like this could have the best

concern with this approach is that you don’t have any control about
indent and you loose pre- and post spacing characters.</span></p>
<p style="margin:15px 0px" class="gmail_msg"><span style="margin-top:0px;margin-bottom:0px" class="gmail_msg">A
concatenating approach is a little tedious but it’s precise. In any
situation a multi-lined string is not softly wrapped string, which
implies that you will have to press enter for each new line you
wish to have. IMHO adding two more characters for each line isn’t
that harmful. ;-)</span></p>

there is a PR for this proposal, but I couldn’t find any up to date

where this proposal is going, and my personal preference are
*continuation quotes*. However the proposed solution is still not
perfect enough for me, because it still lacks of precise control
about the trailing space characters in each line of a multi-line
string.</span></p>

to pitch an enhancement to fix the last tiny part by adding the
escaping character ‘' to the end of each line from 1 to (n - 1) of
