# connections

The connections between inputs and outputs that a capture session contains.

## Declaration

```swift
var connections: [AVCaptureConnection] { get }
```

## Discussion

Discussion A capture session automatically forms connections between inputs and outputs when you call the addInput(_:) or addOutput(_:) methods. You can explicitly add connections to a session by calling the addConnection(_:) method.
