PCSC framework removed in Mac OS X 10.11 El Capitan?

OS X El Capitan

You may know that Apple announced the new major version of OS during this week Apple WWDC 2015 (Worldwide Developers Conference). The next major version of OS X is 10.11, is planned for this Fall and is called El Capitan. See OS X El Capitan for some more details.

For even more details you have to go to the (public) web page "OS X v.10.11 API Diffs".

PCSC framework

According to the (public) web page "OS X v.10.11 API Diffs" we have:

It looks like Apple decided to remove the PCSC framework and replace it with CryptoTokenKit, already introduced in OS X 10.10 Yosemite (see "OS X Yosemite BETA and smart cards status" and "OS X Yosemite and smart cards status" for the beginning of the replacement story).

CryptoTokenKit

We also have some changes (to make it work for real?) in the CryptoTokenKit side (both framework and modules).

WWDC sessions

Apple provides 2 security related sessions at the WWDC according to the schedule.

Security and Your Apps
System Frameworks
Your reputation depends on protecting your users' data. Do this by taking advantage of the Security frameworks built into iOS, OS X and watchOS. Find out about new developments in Security and learn the best practices to develop secure apps and protect your users' data.

Security and Privacy Lab
System Frameworks
Get together with the Apple security and privacy teams for expert advice on protecting your apps, safeguarding your users' data, and honoring your users' privacy. Bring your code and your questions.
It may be interesting to watch the videos of the sessions once they are available. Or may they are not related to smart card at all.

Conclusion

PC/SC application developers, maintainers and vendors will have some work to port/rewrite the PC/SC code to CryptoTokenKit. And the delay is very short to be ready for the release of OS X El Capitan (in 3 months ?).

Thanks to Karl T. for the notice.

Update

PCSC framework will be present in El Capitan. See "PCSC framework will stay in Mac OS X 10.11 El Capitan".
