We're going to implement the class that exposes cryptography-related features. First, I create a new file called KeychainFacade. So let's add a new file, Swift file, and it's called KeychainFacade. We'll rely on the security framework, so let's import it. Next, I declare the KeychainFacade class. First, we'll generate the private key. I'll use the keychain to store the generated key securely. We start the key creation by defining a unique tag of type data, so I create a private static constant, let's call it tagData equals. We'll create a string constant and convert it to data. It should be unique, so let's call it com.asymmetricCryptoDemo.keys.mykey. And I convert it to data using the Strings data method, using a UTF-8 encoding, next, I define the dictionary with the attributes of the key. The keys should be…
