Using Web APIs (Application Programming Interface) and JSON (Java Script Object Notation)
About This Course
Participants will learn about Swift's powerful closure concept and how it can be used to store code that can be executed at a later stage. They will be introduced to the concept of extensions and how they are used to add functionality to current types by creating new properties or methods to extend these types while keeping the original source code. This module also covers the concepts of serialising data to a format that can be saved and then writing and reading data from files on disk.
Participants will also learn how Automatic Reference Counting (ARC) manages memory usage in Swift. They will be introduced to system view controllers such as the activity controller, image picker and alert as a way of extending app functionality. They will also learn how to create custom input forms for gathering data from users.
This module goes into detail about the built-in iOS tools for sending and receiving data from the web, a common feature in apps, as well as utilising the Codable protocol to convert between JSON (Java Script Object Notation) and Swift objects.
