#273
In the refactoring series, Soroush mentioned a protocol he uses to make initializing view controllers from a storyboard as easy as adopting a protocol (and completely type-safe). In this episode we will build this using Swift protocol extensions. The end result is something you can easily carry with you from project to project.

#272
This episode wraps up the refactoring series by implementing the transition to the PhotosViewController. Ben and Soroush talk about the overall process and benefits of coordinators as a pattern to clean up view controllers and organize logic around how your app is stitched together.
lock
#271
Moving on to the next segue in our storyboard, this time Ben and Soroush tackle the Add Review flow. They discuss naming of delegates, the ideal place to perform logic such as preparing a model to be saved and where mutations to the model live. They end up with a view controller that is completely decoupled from the AddReviewViewController and a better picture of what the coordinator tends to look like.
lock
#270
In this episode, Soroush and Ben create the first delegate for a view controller in order to pull out the behavior a user might trigger by interacting with the view controller. This delegate conformance is added to our coordinator so this flow logic is in one place (and not in the view controller).
lock
#268
What is the Coordinators pattern, and why is it useful? Soroush and Ben discuss this and then get started refactoring an existing application that uses Storyboards into using Coordinators. We implement our first AppCoordinator and wire it up on launch.

#265
Have you ever wanted to replicate the 3D Touch actions that are available in Mail.app? How do you make these custom interactions beyond the simple action sheet that you get out of the box? In this episode Conrad walks us through adding custom interaction using 3D Touch to a list building application.
lock
#262
Conrad Stoll shows us how to implement Peek and Pop using 3D Touch on supported devices. We learn how to do it in code versus the storyboard, as well as how to customize the display and presentation of the previewed view controller.

Wrapping up our custom download button, this time we focus on the highlighted image and depressed state of the button, as well as transitioning to and from the progress layer.
lock
#242
In this episode we create a custom control to serve as our download button. We start by creating a circular progress indicator using CAShapeLayer, then move on to subclassing UIControl to provide our image view and touch handling.
lock
#241
In this episode we take the download state and progress notifications and update the user interface to reflect this state. We'll see how to translate the notification into the indexPath for that episode row, and how to fake a change related to the fetched results controller to trigger a reload of the content. We will leverage the RateLimit library to save periodic changes in progress to the model without overwhelming Core Data.
lock
#240
In this episode we create a DownloadInfo model in CoreData in order to track the state of a download, separate from any view controller.
lock
#239
Downloading large files on iOS represents some unique challenges. Downloads should occur in the background, not confined to a particular view controller. They should be able to report progress on multiple screens, and should be robust enough to survive application suspension and failing network conditions, and respect the user's cellular data plan. In this episode we start a series on downloading large files that will cover all of the above concerns.
lock
#235
In this episode we take a look at UIPasteboard, allowing us to inspect, copy, and paste content on the system pasteboard as well as your own custom pasteboards. We'll also look at adding multiple representations of the same item to be a better OS citizen, for instance by copying rich text alongside plain text.
lock
#234
Universal Links is a great feature that allows us to render content in an app when a user hits a known URL, instead of opening Safari. For content-based applications, this can be especially useful, as often records that exist on the web also exist in the app. We'll leverage our work from Episode 231 on Shared Web Credentials and extend the demo app to take advantage of Universal Links.

#232
UIView has an incredibly useful spring-based animation API, but it can be difficult to know what to use for the damping and initial spring velocity parameters. In this episode, we'll break down how to compute the velocity value using the values we get from our UIPanGestureRecognizer and a little math.
lock
#231
In this episode we implement shared web credentials with a server, allowing users to automatically enter credentials in our app if they've already done so in Safari. We cover building a Sinatra app for our server, deployment to Heroku for free SSL and a unique domain, and adding the appropriate entitlements to our app.

#227
Continuing our series on building out our Activity++ clone, this time we hook up our application to HealthKit, displaying real data in the app from a device. We continue to use our wrapper type so that the application can still work in the simulator with randomized data, which also allows us to set up certain scenarios that we wish to test, such as streaks.

#226
In this episode we examine the scrolling performance of our activity ring views. We see that framerate suffers when scrolling quickly, then apply a few changes to bring scrolling performance back to 60 frames per second.

#225
This week we take our ring views and use them to create a collection view of rings, one for each day in an entire year.
lock
#223
Let‘s attempt to recreate Activity++, an application by _David Smith. The app features a number of interesting interface elements that would be interesting to try to build ourselves! In this part we'll start out by replicating the ring views for a given day.
