Setup FaceAnchor

Before you begin, please update iOS ARCloud SDK to version 0.4.16 or later. You may reset the package cache in Xcode if a new function did not show up.

FaceAnchor only works with Apple devices that support FaceID. You can see the device list to learn more https://support.apple.com/en-us/HT209183 (opens in a new tab)

To add face detection to AR experience, simply add startFaceAnchor(Bool) when you init service. An AR session will be switched to the front camera.

let arCloudUIView = ARCloudUIView(service: self.graffityARCloud, startFaceAnchor: true, nodeTouchDelegate: self)

To work with both front and back cameras, you can create them in 2 views separately. For example in the code block below:

// This is just an example code in UIViewController class.
 
let arCloudUIViewFront = ARCloudUIView(
    service: self.graffityARCloud, 
    startFaceAnchor: true, 
    nodeTouchDelegate: self)
 
let arCloudUIViewBack = ARCloudUIView(
    service: self.graffityARCloud, 
    nodeTouchDelegate: self)
 
// Open each ARView with an iOS button action
@objc func openFrontAR() {
    self.present(arCloudUIViewFront)
}
 
@objc func openBackAR() {
    self.present(arCloudUIViewBack)
}
