The GeocodingClient class returns stub data for the time being. In this episode, we integrate the Core Location framework and take advantage of the geocoding APIs it offers. We use the geocoding APIs to forward geocode the address the user enters in the TextField of the AddLocationView to a collection of Location objects.

The AddLocationView displays stub data for the time being. We change that in this and the next episode by integrating the Core Location framework. Apple's Core Location framework defines an API for forward geocoding addresses. We use that API to convert an address to a collection of placemarks. The application converts the placemarks to Location objects the AddLocationView can display.

In the next few episodes, we populate the AddLocationView. We break this task up into several smaller steps. We first populate the AddLocationView with stub data. Later in this series, we replace the stub data with data provided by the Core Location framework.

In the previous episode, we used the adapter pattern to make the integration of the project with the Google SDK testable. In this episode, we put the theory to the test. We write unit tests for the GoogleAnalyticsService class to validate the integration of the project with the Google SDK.

In the previous episodes, we unit tested the analytics library we built. The integration with the Google SDK is an aspect of the implementation we haven't talked about in detail. We shouldn't unit test the Google SDK itself, but can we unit test the integration with the project? That is the question we focus on in this episode.

In the previous episodes, we used code coverage to help us write unit tests for the analytics library we built. This worked fine, but code coverage isn't perfect. Code coverage inspects which lines of code are executed when the test suite is run. The result may be misleading or incorrect at times. In this episode, we take a look at an important shortcoming of code coverage.

In the previous episode, we wrote the first unit test for the analytics library we built. In this episode, we write a few more unit tests and take advantage of the compiler to find gaps in the test suite.

The analytics library we built in this series is easy to use thanks to its intuitive API. The call site is no longer littered with string literals and the API the analytics library exposes is type safe. We don't stop here, though. I promised you that the analytics library would be testable. Let's focus on that aspect in the next few episodes.

The analytics library we are building is tightly coupled to the GoogleAnalyticsClient class. Tight coupling negatively impacts testability and it is often an indication that there is room for improvement. In this episode, we decouple the analytics library from the GoogleAnalyticsClient class by taking a protocol-oriented approach. Let me show you how that works.

We drastically improved the analytics code of the NotesViewModel class in the past few episodes, but we still use a few string literals at the call site. That is something we address in this episode.

If you're anything like me, then you're used to solving complex problems with logic and structure. That's what developers do. Right? But outside of our screens, nature reminds us that not everything runs on neatly written code. Some of the most rewarding systems, the ones that fuel our creativity and give us balance, are messy, alive, and organic.
