# init(forTrust:)

Creates a URL credential instance for server trust authentication with a given accepted trust.

## Declaration

```swift
init(forTrust trust: SecTrust)
```

## Parameters

- `trust`: The accepted trust.

## Return Value

Return Value A new URL credential object, containing the accepted server trust.

## Discussion

Discussion Before creating a server trust credential, it is the responsibility of the delegate of an NSURLConnection instance or an NSURLDownload instance to evaluate the trust. Do this by calling SecTrustEvaluate(_:_:), passing it the trust obtained from the serverTrust method of the server’s URLProtectionSpace instance. If the trust is invalid, the authentication challenge should be cancelled with cancel(_:).
