# anyOf(_:)

Returns a character class that matches any character in the given string or sequence.

## Declaration

```swift
static func anyOf<S>(_ s: S) -> CharacterClass where S : Sequence, S.Element == Character
```

## Discussion

Discussion Calling this method with a group of characters is equivalent to listing those characters in a custom character class in regex syntax. For example, the two regexes in this example are equivalent: let regex1 = /[abcd]+/ let regex2 = OneOrMore(.anyOf("abcd"))
