What is your evaluation of the proposal? –1 for the proposed solution, but in general I’d myself would want to see multi-line strings in Swift. The current proposal does not cover precision, which could also be desired by developers.
My _personal_ view on how I wish multi-line strings do behave is actually similar to the magical string concatenation which is an optimization during compile time (not included in Xcode 8.3). Many people disagree with this point of view in favor of implicit new lines and non escaped " character, which is fine by me only if we can extend the standard string literal to support multilines too. Such extension will be stricter and have special precision rules. // 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" Additionally you can support a similar version of multilines strings with """ notation for those of use who are lazy to type \n and \" and want implicit new lines. However this raises the question, if the addition of """ is warrant it’s existence only for laziness and copy pasting? The above example should also support string interpolation. Is the problem being addressed significant enough to warrant a change to Swift? Not enough from my point of view. Does this proposal fit well with the feel and direction of Swift? The addition of multi-lined strings does fit, however I don’t think the proposed solution satisfies everyone. Personally I’d probably never use a multi-lined string as proposed, just because it adds implicit new lines to my very long string, which I maybe only want to break up into a few lines for better readability without the boilerplate of the not so obvious optimization magic provided by the complier though the concatenation operator +. I think the correct name is *multi line string literal*, which is different from _multi line string_. The former should not have any implicit behavior except if there are two different versions like "__" and """___""". If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those? Javascript has this nice ability to break up strings into multilines with trailing precision, which I used in the example above. How much effort did you put into your review? A glance, a quick reading, or an in-depth study? Read the whole proposal and took part in latest discussion thread. -- Adrian Zubarev Sent with Airmail Am 6.

The goal of the review process is to improve the proposal under review through constructive criticism and, eventually, determine the direction of Swift. When writing your review, here are some questions you might want to answer in your review: • What is your evaluation of the proposal? • Is the problem being addressed significant enough to warrant a change to Swift? • Does this proposal fit well with the feel and direction of Swift? • If you have used other languages or libraries with a similar feature, how do you feel that this proposal compares to those? • How much effort did you put into your review?
