# init(scheme:host:path:)

Initializes a newly created NSURL with a specified scheme, host, and path.

```
convenience init?(scheme: String, host: String?, path: String)
```

## Parameters

`scheme`

The scheme for the NSURL object. For example, in the URL `http://www.example.com/index.html`, the scheme is `http`.

`host`

The host for the NSURL object (for example, `www.example.com`). May be the empty string.

`path`

The path for the NSURL object (for example, `/index.html`). If the path begins with a tilde, you must first expand it by calling [`expandingTildeInPath`](/documentation/Foundation/NSString/expandingTildeInPath).

## Return Value

The newly initialized NSURL object.

## Discussion

This method automatically uses percent encoding to escape the `path` and `host` parameters.
