Networking is a common component of modern mobile apps, necessary for authenticating user accounts, fetching data, and downloading and uploading files. Learning the latest networking frameworks is vital to quality, maintainable iOS app development. This course covers the basics of Apple-provided network development using URLSession as well as Alamofire, a third-party framework for server-side communication that is generally considered the standard Swift solution. Instructor Bear Cahill shows how to fetch a variety of data types, including text, JSON, binary data, and media files, and handle responses from the server. Plus, learn how to report upload and download progress in Alamofire using method chaining and the built-in progress functions.
