+/// The `ServerTrustPolicy` evaluates the server trust generally provided by an `NSURLAuthenticationChallenge` when
+/// connecting to a server over a secure HTTPS connection. The policy configuration then evaluates the server trust
+/// with a given set of criteria to determine whether the server trust is valid and the connection should be made.
+///
+/// Using pinned certificates or public keys for evaluation helps prevent man-in-the-middle (MITM) attacks and other
+/// vulnerabilities. Applications dealing with sensitive customer data or financial information are strongly encouraged
+/// to route all communication over an HTTPS connection with pinning enabled.
+///
+/// - performDefaultEvaluation: Uses the default server trust evaluation while allowing you to control whether to
+///                             validate the host provided by the challenge. Applications are encouraged to always
+///                             validate the host in production environments to guarantee the validity of the server's
+///                             certificate chain.
+///
+/// - performRevokedEvaluation: Uses the default and revoked server trust evaluations allowing you to control whether to
+///                             validate the host provided by the challenge as well as specify the revocation flags for
+///                             testing for revoked certificates. Apple platforms did not start testing for revoked
+///                             certificates automatically until iOS 10.1, macOS 10.12 and tvOS 10.1 which is
+///                             demonstrated in our TLS tests. Applications are encouraged to always validate the host
+///                             in production environments to guarantee the validity of the server's certificate chain.
+///
+/// - pinCertificates:          Uses the pinned certificates to validate the server trust. The server trust is
+///                             considered valid if one of the pinned certificates match one of the server certificates.
+///                             By validating both the certificate chain and host, certificate pinning provides a very
+///                             secure form of server trust validation mitigating most, if not all, MITM attacks.
+///                             Applications are encouraged to always validate the host and require a valid certificate
+///                             chain in production environments.
+///
+/// - pinPublicKeys:            Uses the pinned public keys to validate the server trust. The server trust is considered
+///                             valid if one of the pinned public keys match one of the server certificate public keys.
+///                             By validating both the certificate chain and host, public key pinning provides a very
