# init(configuration:delegate:queue:)

## Declaration

```swift
init(configuration: NFCTagReaderSessionConfiguration, delegate: any __NFCTagReaderSessionDelegate, queue: dispatch_queue_t)
```

## Parameters

- `configuration`: Reader configuration for the session. The configuration is applied when [NFCTagReaderSession beginSession] or [NFCTagReaderSession restartPolling] is called.
- `delegate`: The session will hold a weak ARC reference to this NFCTagReaderSessionDelegate object.
- `queue`: A dispatch queue where NFCTagReaderSessionDelegate delegate callbacks will be dispatched to. A nil value will cause the creation of a serial dispatch queue internally for the session. The session object will retain the provided dispatch queue.

## Return Value

Return Value A new NFCTagReaderSession instance.
