We've added Swift 4. See our blog for more info.

Looks like Chinese language posts are okay.

I recommend that, if it doesn't look problematic in google-translate, then please, my friend... tinyurl.com/L337-33T-G000

I should note that fanxiangqi's original post was evidently downvoted (all the way to -1 before I returned it to 0).

Regardless, to charitably respond to rogo's request:

The three lines from fanxiangqi represents a three-mode theory of aesthetic qualities of poetry from the Song dynasty, called "jingjie".

Mode 1, a line of poetry from Yan Shu's "Dielianhua." https://en.wikipedia.org/wiki/Yan_Shu
-- Last night the West wind shriveled the green-clad trees.
-- Alone I climb the light tower to gaze my fill along the road to the horizon.
Mode 2: a line from Liu Yong's Fengqiwu
-- My clothes grow daily more loose, yet care I not.
-- For you am I thus wasting away in sorrow and pain.
Mode 3: a line from Xin Qiji's Qingyuan https://en.wikipedia.org/wiki/Xin_Qiji
-- I sought her in the crowd a hundred, a thousand times.
-- Suddenly with a turn of the head [I saw her], that one there where the lamplight was fading.

Basically... this is deep philosophy stuff that no person has a chance of comprehending unless they are well-versed in classical Chinese writings.

I love this site! It's great for warming up and practice. I would love it if you updated the Swift language to Swift 4 as it adds changes to Strings and other functionality. Thank you!
