In my project, I am trying to support triple cameras system. But I don't know how to check whether a device has triple cameras?

CodePudding user response：

you can do this with following code either device has builtin dual back camera or wide angle back camera

var currentDevice:AVCaptureDevice?
        if let device = AVCaptureDevice.default(.builtInDualCamera, for: AVMediaType.video, position: .back)
        {
            currentDevice = device
        }
        else if let device = AVCaptureDevice.default(.builtInTripleCamera, for: .video, position: .back)
        {
            currentDevice = device
        }
        else if let device = AVCaptureDevice.default(.builtInWideAngleCamera, for: AVMediaType.video, position: .back)
        {
            currentDevice = device
        }
        else
        {
            print("Error: no camera available")
        }

Hope this will helps you
