Question

可以使用TelephotoCamera从WideAngleCamera，automatically或DualCamera获取相框：

//auto
let device = AVCaptureDevice.default(.builtInDualCamera, for: .video, position: .back)
//telephoto
let device = AVCaptureDevice.default(.builtInTelephotoCamera, for: .video, position: .back)
//wideAngle
let device = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .back)

但如何同时从TelephotoCamera和WideAngleCamera获取帧数（使用dual camera s的设备）。

EDIT1
试图向capture session添加2个输入：

captureSession?.addInput(input)
captureSession?.addInput(input2)

NSInvalidArgumentException: Multiple audio/video AVCaptureInputs are not currently supported

的 EDIT2
~~尝试为isDualCameraDualPhotoDeliveryEnabled启用capture photo output标记：~~

~~capturePhotoOutput?.isDualCameraDualPhotoDeliveryEnabled = true~~

~~NSInvalidArgumentException: Dual Camera dual photo delivery is not supported in this configuration~~

的但
isDualCameraDualPhotoDeliverySupported在false上提供iPhone 8 Plus 这可能是我问题的原因吗？

仍然没有运气。

是的，这是可能的。
只需选择正确的配置。

捕获设备应为builtInDualCamera：

let captureDevice = AVCaptureDevice.default(.builtInDualCamera, for: .video, position: .back)

配置捕获会话后配置捕获照片输出：

captureSession = AVCaptureSession()
captureSession?.sessionPreset = AVCaptureSession.Preset.photo
captureSession?.addInput(input)
captureSession?.addOutput(capturePhotoOutput!)

capturePhotoOutput?.isHighResolutionCaptureEnabled = true

<强> capturePhotoOutput?.isDualCameraDualPhotoDeliveryEnabled = true

在拍摄照片之前配置照片设置：

let photoSettings = AVCapturePhotoSettings()
photoSettings.isAutoStillImageStabilizationEnabled = true
photoSettings.isHighResolutionPhotoEnabled = true
photoSettings.isAutoDualCameraFusionEnabled = false

<强> photoSettings.isDualCameraDualPhotoDeliveryEnabled = true

实施AVCapturePhotoCaptureDelegate，并覆盖下一个方法：

public func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?)

您将收到2个photoOutput回调！

同时从两个摄像头（TelePhoto和WideAngle）捕获帧
