Introduction

Introduction to part 2 of the Beginning Networking with URLSession course.

Priorities & Cache Policies

Take a look at how tasks oftentimes require different priorities, as well as defining what will be cached.

Download Music

Apply the concepts learned in the previous lecture, regarding priorities and caching, in order to download music from the iTunes preview API.

Handle Errors

URL requests can sometimes go wrong. Learn how to handle errors during networking operations.

Challenge: Download Images

Leverage the concepts learned in the previous lecture, but apply them towards downloading images corresponding to album artwork.

Show Download Progress

Performing lengthy uploads or downloads without any visual indication of progress is not the best user experience. This episiode will show you how to provide a progress indicator for a download.

Grouping Requests

Learn how to group multiple URLSession tasks so they execute concurrently, but are reported as completed when all requests have finished.

Simulate Different Network Speeds

In order to deliver the best user experience you need to test your appls with the same types of network conditions that your users might encounter. This episode will show you how to simulate poor network connections.

Pause, Resume & Cancel Downloads

Apps will likely run into scenarios that require a download or upload to be paused, resumed, or canceled entirely. This episode will cover these topics.

Conclusion
