It has no input arguments and it doesn't return anything either. We'll need a KeychainFacade instance first. So I create a constant let facade equals KeychainFacade. Then I define a constant and assign it the value Super secret text. Let me scroll up a bit. This is the text that we're going to encrypt. So next we'll call the facade method. These methods can throw so we'll call them from within a do catch block. Let's encrypt the text. I'll use optional binding to extract the result of calling facade encrypt into a constant. If let encryptedData equals and I use try to call facade.encrypt and that's passed in our text. If the encryption was successful, I print a console log, print Text encryption successful. Next, we'll decrypt the encrypted data. Again, we use optional binding and the result of calling…
