Instance Method

appending​Path​Component(_:​)

Returns a new URL made by appending a path component to the original URL.

Declaration

func appendingPathComponent(_ pathComponent: String) -> URL?

Parameters

path​Component

The path component to add to the URL, in its original form (not URL encoded).

Return Value

A new URL with path​Component appended.

Discussion

If the original URL does not end with a forward slash and path​Component does not begin with a forward slash, a forward slash is inserted between the two parts of the returned URL, unless the original URL is the empty string.

If the receiver is a file URL and path​Component does not end with a trailing slash, this method may read file metadata to determine whether the resulting path is a directory. This is done synchronously, and may have significant performance costs if the receiver is a location on a network mounted filesystem. You can instead call the appending​Path​Component(_:​is​Directory:​) method if you know whether the resulting path is a directory to avoid this file metadata operation.
