[`SecTrustSettingsResult.trustRoot`](/documentation/Security/SecTrustSettingsResult/trustRoot)

This root certificate is explicitly trusted.

[`SecTrustSettingsResult.trustAsRoot`](/documentation/Security/SecTrustSettingsResult/trustAsRoot)

This non-root certificate is explicitly trusted as if it were a trusted root.
