# url

A URL created from the components.

## Declaration

```swift
var url: URL? { get }
```

## Discussion

Discussion If the NSURLComponents has an authority component (user, password, host or port) and a path component, then the path must either begin with “/” or be an empty string. If the NSURLComponents does not have an authority component (user, password, host or port) and has a path component, the path component must not start with “//”. If those requirements are not met, nil is returned.
