Networking

Users always want more. With a background URLSession, we can give them more by extending downloads and uploads beyond the app's lifespan. Here, we look at building a solution to take advantage of a background session to download adorable cat photos 😸.

Codable is a potent tool for simplifying handling API responses. However, sometimes API responses aren't simple. Here, we look at how to handle decoding a JSON response where the returned types keep changing.

Many of us feel nervous when meeting a group of people for the first time. Your app is the same. Here, we look at how SSDP can offer a convenient way for your app to get to know its local network and overcome those nerves.

Operations have a reputation for being chunky, especially compared to GCD. However, once you get to know operations, you realise that they are the OOP approach to concurrency in iOS. Here, we look at how to use operations to build a networking layer by encapsulating multiple steps into one unit.

In iOS, we can use background-transfers to extend the life of our downloads and uploads beyond the app's lifespan, offering our users a better experience by using a background URLSession. Here, we look at how to build that better experience.

Every time a user has to wait for a network request to complete before they can get on with their task, we risk losing them. With pausable downloads, we can ensure that even a cancelled download isn't wasted. Here, we look at how to resume a cancelled download to minimise wait times.

We want to test that our network stacks can make network requests as intended but without actually making those requests. Here, we look at how to split our networking stack into components to allow easy unit testing.

No one wants networking code scattered everywhere. Here, we look at how to utilise NSOperation to encapsulate each networking request within its own cancellable unit of work.

Making a network call and consuming the response is common to most apps. But how do we do it well? Here, we look at building a networking layer to consume a SOAP response.
