Course Description
Understanding and managing the life cycle of an iOS app is an important part of its successful development. In this course, you will learn about the architecture of an iOS app and its execution states. You'll learn how to manage transitions to different states, such as going to the background or foreground. You'll also learn how to manage apps running in the background, including how to implement tasks, download content, and provide notifications.
Learning Objectives
App Architecture and Execution States

Managing State Transitions
- handle launches of an iOS app
- configure an iOS app to launch in landscape mode
- configure an iOS app to access app-specific data files at first launch
- handle temporary interruptions in an iOS app

- implement Handoff in iOS apps in order to enable transfer of activities from one device to another
Background Processing
- implement background processing to execute finite-length tasks in an iOS app
- download content in the background in an iOS app
- implement long-running tasks in iOS applications
