# xpc_connection_resume(_:)

Resumes a suspended connection.

## Declaration

```swift
func xpc_connection_resume(_ connection: xpc_connection_t)
```

## Parameters

- `connection`: The connection object which is to be manipulated.

## Discussion

Discussion In order for a connection to become live, every call to xpc_connection_suspend(_:) must be balanced with a call to xpc_connection_resume(_:) after the initial call to xpc_connection_resume(_:). After the initial resume of the connection, calling xpc_connection_resume(_:) more times than xpc_connection_suspend(_:) has been called is considered an error.
