# acceptConnection(fromPeer:)

Called by the delegate to accept a connection request received from a remote peer.

```
func acceptConnection(fromPeer peerID: String!) throws
```

## Parameters

`peerID`

The string identifying the peer that initiated the connection to the session.

## Discussion

When your session acts as a server, client peers can discover your session and attempt to connect to it. When a client attempts to connect to the session, the delegate’s [`session(_:didReceiveConnectionRequestFromPeer:)`](/documentation/GameKit/GKSessionDelegate/session(_:didReceiveConnectionRequestFromPeer:)) method is called to decide whether the peer should be connected. Your application calls this method to accept the request, or [`denyConnection(fromPeer:)`](/documentation/GameKit/GKSession/denyConnection(fromPeer:)) to reject it.

> Handling Errors in Swift:
> In Swift, this method returns `Void` and is marked with the `throws` keyword to indicate that it throws an error in cases of failure.
> 
> You call this method in a `try` expression and handle any errors in the `catch` clauses of a `do` statement, as described in [Error Handling](https://docs.swift.org/swift-book/LanguageGuide/ErrorHandling.html) in [The Swift Programming Language](https://docs.swift.org/swift-book/) and `About Imported Cocoa Error Parameters`.
