```

```

## Parameters

- `completionHandler`: The handler to call when the renewal has completed.

## Discussion

Discussion important: You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration: func renewCredentials(for account: ACAccount!) async throws -> ACAccountCredentialRenewResult For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously. For Twitter and Sina Weibo accounts, this method prompts the user to go to Settings to re-enter their password. For Facebook accounts, if the access token has become invalid due to a regular expiration, this method obtains a new one. If the user has deauthorized your app, this renewal request returns ACAccountCredentialRenewResultRejected.
