In this previous section, we shared a single, simple class that exposed a platform-specific string. This demonstrated how we can leverage the expect and actual modifiers, but the overall example was quite simple. In this section, let's look at a slightly more interesting example of how we can architect common code and consume it across the different projects we've created.
