# appendingPathComponent(_:)

Returns a URL by appending the specified path component to self.

## Declaration

```swift
func appendingPathComponent(_ pathComponent: String) -> URL
```

## Parameters

- `pathComponent`: The path component to add.

## Discussion

Discussion For file URLs, this method may perform file system I/O to determine if the path component is a directory, and, if so, it appends a trailing slash /. Use appendingPathComponent(_:isDirectory:) if you know the component’s file system object type in advance. New code should use appending(path:directoryHint:) instead of this method.
