206 more tableview customization
In this episode we continue with our Starcraft II Guide application, this time focusing on using a table view to edit a model. We leverage a cell with a text field, a cell to select data from another view controller, and a section that is only editable/reorderable with itself.
#205
205 tableview customization
In this episode I take a stock UITableView and UINavigationController and customize their appearance to match a design for a Starcraft II companion app. We'll leverage Swift enums to capture colors & fonts so we can reuse them in multiple places. We will also utilize the UIAppearance API to style all instances of a UINavigationBar, and get rid of UITableViewCell's default separator indentation.

204 json api client part 2
In this episode we start writing an application-specific API Client. We use Argo to decode our JSON response into an Episode model, including some nested object decoding, date formatting, and wrap it up by testing the implementation to make sure it works.
#203
203 json api client
In this episode I start creating a reusable api client that will make it a lot easier to consume a JSON api and convert the response into model objects. It uses Argo for the JSON parsing, and leverages Swift features to provide a rich callback for the API calls.

202 building a watchkit complication
In this episode we are joined again by Conrad Stoll
#201
201 building a watchkit glance
In this episode Conrad Stoll joins us once again to extend the watchOS 2 app to include glance, indicating to us when our beer will be ready. He leverages a new timer class that allows you to accurately display a countdown (or count up) timer that runs completely on the watch.
#200
200 watchkit app
In this episode we are joined by Conrad Stoll who shows us how to build a watchOS 2 app to order beer. Data is synchronized from an iOS app, and the digital crown is used to make selections.
#199
199 nsstv part 2 icons and artwork
In this episode we use Sketch to export top shelf artwork and layered icons for tvOS. We then preview the layered artwork using the Parallax Previewer tool. We then add these to our asset catalog in Xcode to add them to our application.
#198
198 nsstv part1 project setup
In this episode we start a new series on building the NSScreencast tvOS application. We'll start off by creating the Xcode project, initialize our Gemfile and Podfile for dependencies, as well as talk about a few ways of getting around issues where a 3rd party library doesn't indicate that it supports tvOS yet.
#197
197 mastering tv focus
In this episode we take a deep look at how focus works with tvOS. We learn how to use UIFocusGuide to redirect focus when the engine cannot find an appropriate element to focus. We also learn some debugging tricks on how to visualize focus moves using Quick Look, and how to use _whyIsThisNotFocusable to troubleshoot lack of focus. Finally we'll learn about custom focus animations and layered images.
#196
196 careplicatorlayer
In this episode we take our missile animation from last time and update it to use CAAnimations. Using these animations we can add a wiggle, along with a small oscillating rotation to give a little life to the missile. Then we utilize CAReplicatorLayer to have them fan out and fire in slightly different directions.
#195
195 intro to apple tv
In this episode we dive into tvOS, creating a spaceship dashboard application, complete with animated rockets and a crew list. Ludicrous speed, go!
#194
194 modeling api endpoints
In this episode we talk about modeling API Endpoints as first class types, rather than relying on strings and string interpolation scattered across your application. For this we'll leverage Swift enums with associated values.
#193
193 in app search
In this episode we take a look at how to provide deep search in our iOS applications. We start by leveraging NSUserActivity to provide relevant search results for recent activities to users. Then we look at how to customize the search results with rich metadata. Finally we look at using CoreSpotlight to fully index the content to make it available for search after we launch our app.
#192
192 handoff alt
Supporting Handoff in your iOS / Mac applications can really delight users. In this episode we will build handoff support into an application so that users can continue their task on the web, or in a separate Mac application that is registered to handle that task.

191 swift 2 optionals poster
In this free episode, we take a look at a core Swift 2 feature: Optionals. Unlike Objective-C, where nil is considered a no-op, in Swift nil is specifically recognized by the compiler, which forces you to handle cases where nil might be present in a variable.
#190
190 custom url protocols
In this episode we look at how to create a custom NSURLProtocol to intercept and alter a network request. This can be useful to provide application-wide interception & logging of network requests, alter requests to change parameters or add authentication, sign requests, or to handle custom url schemes.

189 swift 2 functions and extensions
In this free episode, Ben explores Swift 2 functions, how argument labels work, returning tuples, the guard clause, as well as extending behavior on core types.
#188
188 app transport security
In this episode we take a look at App Transport Security, which contains new secure-by-default behavior for NSURLSession, NSURLConnection, or any other CFNetwork-based API. We'll see how to diagnose ATS errors, what the recommended settings are, and how to relax the requirements if needed to allow our network connections to be made.

#186
186 stack view poster 1280
In this episode we talk about one of the coolest new additions to iOS 9: UIStackView. We'll see how to use Interface Builder in Xcode 7 to set up stack views, adjust distribution and alignment, as well as nested multiple stack views for more complex layouts.
#185
185 self sizing cells and dynamic type poster 1280
In this episode we'll learn how to implement self-sizing table view cells in iOS 8. We'll also see what the oft-ignored Compression Resistance Priority and Content Hugging Priority are used for, and finally how to implement dynamic type in our application to support dynamic text sizes.
#184
184 dznemptydataset poster 1280
In this episode we take a look a DZNEmptyDataSet, a useful library for providing a more inviting UI when you have no content to display inside of a table view or collection view. We'll also see how to leverage NSAttributedString to provide styling of the text that is displayed on the screen.
