Based on your comment, it doesn't sound like you fully understand what Apple has opened up to 3rd party developers. The 3rd party apps are not accessing the enclave, they're just using the Touch ID sensor to tell the system it's you, and then the system provides they necessary login info to the app. At least that's how I understand it. And to clarify, based on dugbug's post, the "system" I'm referring to is the Touch ID system, not the OS.
