Very simple swift wrapper for Biometric Authentication Services (Touch ID) on iOS.

There is a SimpleTouchDemo target defined in the project file. This will run in the Simulator or on a device.

Add the following to your Cartfile

github "simple-machines/simple-touch"

• Drag and drop SimpleTouch.xcodeproj into your project in Xcode.
• Add the SimpleTouch framework SimpleTouch (SimpleTouch) as a Target Dependency in Build Phases in your project.
• Add SimpleTouch.framework in the Link Binary With Libraries step in Build Phases in your project if it's not there already.

First of all, import the framework:

import SimpleTouch

Then, check for Touch ID support:

switch SimpleTouch.isTouchIDEnabled {
case .success:
  // All is good. Can use Touch ID for authentication
  break
case .error(let error):
  // TouchID cannot be used. Interrogate error to see why
  break
}

Finally, attempt to authenticate with Touch ID:

SimpleTouch.presentTouchID("Testing Touch ID", fallbackTitle: "Fallback Method") { response in
  switch response {
  case .success:
    // Successful authentication
    break
  case .error(let error):
    // Authentication failed. Interrogate error to see why
    break
  }
}
