# appendPathComponent(_:)

Appends a path component to the URL.

## Declaration

```swift
mutating func appendPathComponent(_ pathComponent: String)
```

## Parameters

- `pathComponent`: The path component to add.

## Discussion

Discussion note: This function performs a file system operation to determine if the path component is a directory. If so, it will append a trailing /. If you know in advance that the path component is a directory or not, then use func appendingPathComponent(_:isDirectory:). New code should use append(path:directoryHint:) instead of this method.
