Managing data is crucial to building dynamic mobile apps. You won't be able to escape the need to save data to a user's device. When that need arises, Core Data can be a powerful tool to help solve the data persistence challenges of just about any app, no matter how big or small. In this course, Core Data Fundamentals with Swift, you'll learn how to set up and architect an app with Core Data so that it's maintainable and testable. First, you'll discover how to create a data model and explore how to save, access, and delete data. Next, you'll explore how to keep a user interface in sync with the data in your persistent store as users interact with your app. Finally, you'll see how to implement changes to your data model, even after your app is published to the App Store. When you're finished with this course, you'll have the foundation you need to start using Core Data in your apps today.
