You can also test it without a device. Use the Face ID simulator to test your code, and it will behave similarly in the iPhone-X.
The simulator does not recognize the face, but allows you to simulate the matching and mismatched edges, if you include the option Enrolled
of Face ID
.
Add the following code to the view controller and try Face-ID
import LocalAuthentication
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
localAuthentication()
}
func localAuthentication() -> Void {
let laContext = LAContext()
var error: NSError?
let biometricsPolicy = LAPolicy.deviceOwnerAuthenticationWithBiometrics
if (laContext.canEvaluatePolicy(biometricsPolicy, error: &error)) {
if let laError = error {
print("laError - \(laError)")
return
}
var localizedReason = "Unlock device"
if #available(iOS 11.0, *) {
if (laContext.biometryType == LABiometryType.faceID) {
localizedReason = "Unlock using Face ID"
print("FaceId support")
} else if (laContext.biometryType == LABiometryType.touchID) {
localizedReason = "Unlock using Touch ID"
print("TouchId support")
} else {
print("No Biometric support")
}
} else {
}
laContext.evaluatePolicy(biometricsPolicy, localizedReason: localizedReason, reply: { (isSuccess, error) in
DispatchQueue.main.async(execute: {
if let laError = error {
print("laError - \(laError)")
} else {
if isSuccess {
print("sucess")
} else {
print("failure")
}
}
})
})
}
}
}
