Am currently working on a new major CB Connect release. Unfortunately Login with Apple will not be implemented. They require payment to create apps and do not provide a test app workflow for testing OAuth apis. So for these reasons it will not be implemented, sorry. No we are not willing to work on customer accounts to implement this either as implementations need to be maintained so I appreciate anyone making such offers, but it's just not an acceptable situation. Unfortunately this is entirely on Apple for being such a closed system with something as standardized as OAuth.
