You will frequently need to integrate legacy systems, older Objective-C frameworks, or external SDKs into your modern Swift application.</p> <p>The problem arises when these external systems have interfaces that are completely incompatible with your app&rsquo;s existing architecture. If you force your app to accommodate these legacy interfaces directly—like dealing with <code>NSArray</code>, untyped dictionaries, and completion handlers—your code quickly becomes a tightly coupled, unsafe mess.</p>
