decrypt on swift

I saw one of your old post on decrypting on swift. can you guide me on how you achieved it. any sources will be very welcomed.

Can you provide more information on what you are looking to achieve here and what old post you had previously seen?

A great CryptoKit reference to checkout in the meantime would be Performing Common Cryptographic Operations, this sample provides examples on using CryptoKit for performing operations like encryption and decryption.
