# NSTextCheckingResult

An occurrence of textual content found during the analysis of a block of text, such as when matching a regular expression.

## Declaration

```swift
class NSTextCheckingResult
```

## Overview

Overview On both iOS and macOS, instances of NSTextCheckingResult are returned by the NSRegularExpression class and the NSDataDetector class to indicate the discovery of content. In those cases, what is found may be a match for a regular expression or a date, address, phone number, and so on. In macOS, instances of NSTextCheckingResult are returned by the NSSpellChecker object to describe the results of spelling, grammar, or text-substitution actions.
