EHFAuthenticator

Simple class for handling Local Authentication using Touch ID. Used in eHarmony iOS App. EHF stands for eHarmony Foundation which is our library of utilities built off Apple Frameworks. iOS 8 only because it requires the LocalAuthentication framework. Only functional on devices equipped with a Touch ID sensor (iPhone 5S, 6, 6+). Will not work in simulator.

Currently supports Swift 1.2 syntax. Will update to Swift 2.0 when Xcode 7 is officially released.

}];

Swift

EHFAuthenticator.sharedInstance.reason = "Authenticate with Touch ID to access secure data"
