You do not want to check the iOS version, sure, it might work but it is a bad practice. Check for the feature instead. See if LAContext is available.

if ([LAContext class]) {
    // touch ID is available for the device
    // call canEvaluatePolicy:error to see if the user has set a fingerprint.
}
