Integration of MobaiBiometric View with plain camera feed

This example shows how to integrate the Biometric Capture Session into your project. The Biometric Capture Session extracts a frame collection from the camera preview.

Add the Capture Session .xcframework inside the project. Link to guide on how to integrate the library inside the project https://www.simpleswiftguide.com/how-to-add-xcframework-to-xcode-project

Create View inside ViewController.

After finishing the import of .xcframework inside the project, you can import the library inside the swift file.

import MobaiBiometric

In the UI for this example app, we use the following:

Create view

private var mbCaptureSessionView: MBCaptureSessionView

Initialisation view with MBCaptureSessionOptions

public init() {
    self.options = MBCaptureSessionOptions()
    self.mbCaptureSessionView = MBCaptureSessionView(options: self.options)
}

Setup View Constraints

view.addSubview(takePictureButton)
        
NSLayoutConstraint.activate([
    mbCaptureSessionView.topAnchor.constraint(equalTo: view.topAnchor),
    mbCaptureSessionView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
    mbCaptureSessionView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
    mbCaptureSessionView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
])

Starts Camera if camera permissions are granted

public override func viewWillAppear(_ animated: Bool) {
    mbCaptureSessionView.onStartCapturing()
}

Stop Capturing

public override func viewWillDisappear(_ animated: Bool) {
    mbCaptureSessionView.onStopCapturing()
}

Adding delegate and implementing the delegate inside View Controller

mbCaptureSessionView.delegate = self

extension ExampleViewController: MBCaptureSessionDelegate { }

Delegate

onInitializing Is executed when the camera it's started successfully

func onInitializing() { } 

onValidation gives you data about the face position @param faceStatus is an enum that sends information about the face

func onValidation(_ status: DetectedFaceStatus)

onCountDown tells the time count down before capturing the image(This method is activated when you are using Automatic Capturing) @param time returns seconds of countdown in UI

func onCountDown(time: Int)

onCapturing is when the user starts capturing the image process

func onCapturing()

onSuccess is executed for MBCaptureSession class when the capture session is successfully finished @param result contains a list of frames.

func onSuccess(result: MBCaptureSessionResult)

onFailure is executed for MBCaptureSessionService class when the camera can not be @param error describes whether there is a camera or face failure

func onFailure(error: MBCaptureSessionError)
