A string might never be printed or read by a human outside of the code it resides in. In this case it seems perfectly reasonable to ask that it be possible to format the string nicely in the code and disregard how it would actually be printed.<br class=""></blockquote><div class=""><br class=""></div><div class="">Can you give an example of such a use case, where a string is never seen by a human but one cannot insert literal newlines and would need elided ones instead?</div></div></div></div></div></blockquote><br class=""></div></span><div class="">The most common reason is that the code is maintained by a (non-human) developer, who wants to be able to see and update the code in a readable form, but that represents a single line that will automatically wrapped by, for example, a UITextView for (human) consumption. </div></div></blockquote><div class=""><br class=""></div><div class="">A different scenario from what Robert's describing, but sure. This goes to my question to David Hart. Isn't this an argument for a feature to allow breaking a single-line string literal across multiple lines?
