1``gt`` means "greater than", and ``>`` in an escaped form of ">" – Binkan Salaryman Jun 18 '15 at 08:28

1`>` means `>`, altogether it is `->`. – holex Jun 18 '15 at 10:11

-> represent the -> mark. And " represent the single " quote. – Raksha Saini May 31 '17 at 11:36

There is no > in swift function declarations - someone botched up the HTML rendering in the page you were reading. It was supposed to be -> (an arrow made up of a hypen and the greater than operator) that's used to denote the return type of the function.
The text was supposed to read
func example(titles: [String]) -> [UIButton] {
}
Which means the example function has one parameter called titles of type [String] (array of String) and it returns a [UIButton] (array of UIButton).

Assuming you're talking about -> the portion after that denotes the return value of the function.
