The WWDC 2015 sample code includes very good examples of Swift standard library usage in the Swift Standard Library sample. For example, there's code like how to retrieve substrings correctly:

var str = "Héllo, 🇺🇸laygr😮und!"

let range = advance(str.startIndex, 4)...advance(str.startIndex, 12)
str[range.startIndex]
str[range]
str[advance(str.startIndex, 7)]

You can find all the samples here.
