  • HTTP in Swift, Part 15: OAuth

    The last post covered the basics of an OAuth flow: how we check to see if tokens, how we ask the user to log in, how we refresh the tokens, and so on. In this post we’re going to take that state machine and integrate it into an HTTPLoader subclass.

  • HTTP in Swift, Part 14: OAuth Setup

    While Basic Access authentication works for “basic” cases, it is far more common these days to see some form of OAuth used instead. There are some interesting advantages that OAuth has over Basic authentication, such as:

  • HTTP in Swift, Part 13: Basic Authentication

    HTTP requests to web apis frequently need to have some sort of credential to go with them. The simplest kind of authentication is Basic Access authentication, and in this post we’ll be adding this feature to our library.

  • HTTP in Swift, Part 12: Retrying

    Most networking libraries have the ability to automatically send a request again if the received response wasn’t quite what the client was looking for. Let’s add that to our library as well.

  • HTTP in Swift, Part 11: Throttling

    I once worked on an app that used a Timer to periodically ping a server with a status update. In one build of the app, we noticed that the status server started experiencing CPU spikes, eventually culminating in it not being able to handle any more requests.

  • HTTP in Swift, Part 10: Cancellation

    Cancelling an in-progress request is an important feature of any networking library, and it’s something we’ll want to support in this framework as well.

  • HTTP in Swift, Part 9: Resetting

    There are a couple remaining changes we need to make to our loading interface, and one of them is to allow resetting.

  • HTTP in Swift, Part 8: Request Options

    So far we’ve written enough code to describe a chain of HTTPLoader instances that can process an incoming HTTPRequest and eventually produce an HTTPResult.

  • HTTP in Swift, Part 7: Dynamically Modifying Requests

    In this post, we’ll be creating an HTTPLoader subclass that will allow us to dynamically modify requests.

  • HTTP in Swift, Part 6: Chaining Loaders

    So far, the HTTPLoading types we’ve created have all been loaders that directly respond to an HTTPRequest. In order to create new kinds of loaders, we’ll need to revisit the HTTPLoading protocol.
