Swift syntactic sugar wishlist

Regex literals and operators

let re = /regex/
if "xyz" =~ /regex/ {  }

Optionals as conditionals

let maybe: String?
if maybe != nil { } // works
if maybe { } // should work :)
if !maybe { } // this too

Array <<

var array = [ Int ]()
array << 123

NSDate math

let x = NSDate()
let tomorrow = x + 1
let nextMonth = x << 1

This is your big chance!

• CGMath
• MKMath
• UIColor

The String API should be much bigger. At the very least we need Int ranges and .length. Ditto for Array and Dictionary.

If you don't put these into stdlib we'll be stuck with millions of buggy libraries as everyone tries to implement this themselves. See:

• ExSwift
• Dollar

Numeric promotion (pretty please?)

let x = 3
let y = 0.5
let z = x + y
