Strings are collections again
Available from Swift 4.0
This is a small change, but one guaranteed to make a lot of people happy: strings are collections again. This means you can reverse them, loop over them character-by-character, map() and flatMap() them, and more. For example:
let quote = "It is a truth universally acknowledged that new Swift versions bring new features."
let reversed = quote.reversed()
for letter in quote {
print(letter)
}
This change was introduced as part of a broad set of amendments called the String Manifesto (apple/swift).
