# isMultiCamSupported

A Boolean value that indicates whether a multi-camera capture session supports this format.

## Declaration

```swift
var isMultiCamSupported: Bool { get }
```

## Discussion

Discussion When performing single-camera capture using AVCaptureSession, you may set any of the device’s formats as its activeFormat. However, when using AVCaptureMultiCamSession, you may only set the device’s format to one in which isMultiCamSupported is true. Only this limited subset of capture formats can run sustainably in a multi-camera capture scenario.
