```

```

## Discussion

Discussion note: 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 deleteCredentials(forBorderAgent borderAgentID: Data) async throws For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously. The Border Agent is the software component running in the Thread Border Router responsible for advertising itself in the Wi-Fi or Ethernet network. Call the method as follows: func removeCredentials(borderAgentID: Data) async -> (Error?) {     let client = THClient()     var err:Error?     do {         err = try await client.deleteCredentials(forBorderAgent: borderAgentID) as? Error     } catch {         err = error     }     return (err) }
