Swift standard documentation comment

Question

Is there a standard way to write documentation comment in the Swift language? Something equivalent to javadoc (Java) or docstrings (Python)?

example:

Answer 1

There are two types of Documentation comments single line "///..." and multiline "/**...*/" documentations NSHipster explains it here

Sample code copied from the website:

/**
    Repeats a string `times` times.

    - Parameter str:   The string to repeat.
    - Parameter times: The number of times to repeat `str`.

    - Throws: `MyError.InvalidTimes` if the `times` parameter 
      is less than zero.

    - Returns: A new string with `str` repeated `times` times.
*/

func repeatString(str: String, times: Int) throws -> String {
    guard times >= 0 else { throw MyError.InvalidTimes }
    return Repeat(count: 5, repeatedValue: "Hello").joinWithSeparator("")
}
