# rangeOfCharacter(from:)

Finds and returns the range in the string of the first character from a given character set.

```
func rangeOfCharacter(from searchSet: CharacterSet) -> NSRange
```

## Parameters

`searchSet`

A character set. This value must not be `nil`.

    Raises an [`invalidArgumentException`](/documentation/Foundation/NSExceptionName/invalidArgumentException)     if     `aSet`     is     `nil`    .

## Return Value

The range in the receiver of the first character found from `aSet`. Returns a range of `{``NSNotFound``, 0}` if none of the characters in `aSet` are found.

## Discussion

Invokes [`rangeOfCharacter(from:options:)`](/documentation/Foundation/NSString/rangeOfCharacter(from:options:)) with no options.
