#pragma mark representation method in Swift

Use #pragma mark - to separate and identify code in OC to generate separation lines

Use #pragma mark function specification to generate a function specification X

But in swift, this syntax is not supported. After all, it belongs to C syntax, so there are new syntaxes, such as: // MARK: // FIXME // TODO: etc.

// MARK: - generate divider

// MARK: Description

Don't forget that colon. . .
