For this reason, various high-level programming languages have introduced a <code>Result</code> type into their libraries, on top of their existing error-handling features. This feature was implemented in Swift 5.</p> <p>A <code>Result</code> wraps a success or a failure. It is essentially an <code>enum</code> with two possible cases: <code>.success</code> and <code>.failure</code>. The <code>.success</code> case wraps the correct result of an operation, whereas a <code>.failure</code> wraps an <code>Error</code>. Its implementation uses generics, so you always know what you are going to get back.</p>
