That’s not correct. You can do RSA encryption and decryption using Security Transforms. Check out the CryptoCompatibility sample code.

Note In macOS 10.12 and iOS 10 we are enhancing the SecKey API so that you’ll have one simple API for asymmetric encryption on both platforms. Yay! For more details, watch WWDC 2016 Session 706 What’s New in Security.
