Instance Method

range(at:)

Returns the result type that the range represents.

Declaration

func range(at idx: Int) -> NSRange

Parameters

idx

The index of the result.

Return Value

The range of the result.

Discussion

A result must have at least one range, but may optionally have more (for example, to represent regular expression capture groups).

Passing range(at:) the value 0 always returns the value of the the range property. Additional ranges, if any, will have indexes from 1 to numberOfRanges-1.
