aiDee (/ɪd/), noun
"... abbreviation for identification: any official card or document with your name and photograph or other information on it that you use to prove who you are."
aiDee is a Swift micro-framework that can be used to authenticate with iOS Devices using biometrics: Touch ID or Face ID. Written in Swift this aims to be a simple example of Apple's not-so-new LocalAuthentication API usage.
- Swift 5.1
- Xcode 11
- iOS 11
As a first step you should add an entry on your Info.plist
file for key NSFaceIDUsageDescription
.
The value should be a string describing the reason why your app uses Touch or Face ID. More information on this subject can be found on Apple's Documentation.
aiDee is available through CocoaPods.
Just add the following line to your PodFile
:
pod 'aiDee'
And then run the following command on the terminal:
pod install
- Carthage
Add the entry to your Cartfile
:
github "aiFigueiredo/aiDee"
And then run the following command on the terminal:
carthage update
Add the package to your Package.swift
file, under dependencies:
dependencies: [
.package(url: "https://github.com/aiFigueiredo/aiDee.git", from: "1.0.1")
]
import aiDee
...
// Instantiate BiometricAuthentication object
let biometricAuth = BiometricAuthentication()
// Get Biometric Availability Information
let biometricsAvailable: Bool = biometricAuth.isBiometricsAvailable()
let biometricsType: BiometricType = biometricAuth.biometricType() // .touchId / .faceId / .none
// Authenticate using Biometrics providing a LocalizedString with a reason for the request
biometricAuth.authenticateUser(localizedReason: "Reason for Biometric request") { [weak self] result in
switch result {
case .success: self?.showAlert(title: "Success", message: "Biometric Auth Successful")
case .failure(let error): self?.showAlert(title: "Error", message: error.errorDescription)
}
}
- Both FaceID and TouchID can be tested in the simulator by selecting "Hardware" > "TouchID"/"FaceID" > "Enrolled"
- This micro framework should be used alongside the use of Keychain to store sensitive information.
