Quoted from The Swift Programming Language iBook

Does this mean you can't simply see if a boolean is true by doing something like if(trueBool){...} and requires to put YES or TRUE like if(trueBool==YES){...} ?

I'll mention custom operators in my talk , and I'm pretty sure they're covered in the guide, but essentially you just declare the operator somewhere in the program:
Swift code:
operator infix|postfix|prefix %%% {
  // You can skip these and Swift will just complain if you ever write this next to another binary operator.
  // associativity left|right
  // precedence some-magic-number
}
And then you define a global function with that name:
Swift code:
func %%%(a: Int, b: Int) -> (Int,Bool) {
  // whatever
}

I was just reading about this. If I'm understanding correctly, it can be any sequence of the following 14 characters: / = - + * % < > ! & | ^ . ~

. is restricted. You can also use non-ASCII characters; we haven't decide exactly which set, but it'll include the math symbols for sure.

Awesome! Someone in another thread about Swift wanted to use ∈ really badly.
