In iOS 8, Apple provided a new framework named LocalAuthentication which lets us use the TouchID biometric authentication mechanism to our applications. TouchID was first introduced in iOS 7 as an alternative way to unlock iPhone 5s devices and make purchases in the App Store. Here I have created a “plug and play” class written in Swift, which you can add to your projects and integrate the TouchID authentication to your applications without performing any custom implementation at all, even without you need to know the TouchID details at all.
