Top-notch video tutorials for Swift developers

In this episode I start recreating an old app for toddlers called Giggletouch. In the video I use SpriteKit to render shapes that are subsequently rotated, scaled, and faded. The shapes are drawn with Sketch and random colors are applied to the shape at runtime.

In this episode we take a look at a couple of new features in Xcode 5.1. The first is creating your own Quick Look representations for custom objects, which can be quite a handy feature for visualizing data (such as images, locations, and paths). The second is a new Autolayout constraint in Interface Builder called "Aspect Ratio" which can further help describe your intent when laying out views with Autolayout.

In this episode we fix the problem of a scroll view blocking touches to a UITableViewCell by forwarding touch events from the scroll view and onto a delegate, which manages the cell's highlighted state properly.

In this episode we add Core Data to our Weight Tracker application, but we lean on a new library called MDMCoreData to set up our Core Data stack for us. Using MDMCoreData we can get a sensible parent/child context set up where the main context is a child of the parent writer context. We also leverage a handy class that dovetails with NSFetchedResultsController to display records in a UITableView.

UIStoryboards can help visualize your screen flow and even describe how to transition between view controllers using segues. In this episode I'll show you how you can take advantage of built-in support to unwind segues to back to where you came from. I'll show the automatic way as well as how to manually unwind a segue.

In this episode I customize UITableViewCell to provide swipe to reveal behavior, similar to Mail.app. We use UIScrollView's delegate methods to ensure that we never land mid-way through the swipe, raise notifications to make sure only one cell is open at a time, and we use a help app called Reveal to assist us in visualizing the view hierarchy.

In this episode I cover how to extend UITableViewCells to provide a swipe action, marking an item as read or unread. Combined with a nifty little progress animation, this adds functionality to your table view cells without requiring extra buttons or action sheets.

In this episode we examine the difference between strong and copy semantics for properties, and why you'd favor copy for types such as NSString and NSArray.

In this episode we tackle how to implement an ever increasing trend in iOS 7 app design: blur. We start by doing it the "easy" way using UIToolbar, then move on to a more custom and flexible approach using our own blurred image.

In this episode we wrap up our refactoring of a complex view controller, this time introducing a model, factoring out a new data source class, and more.

In this episode I take a fairly simple application with a single view controller and examine how we can refactor it into more discrete parts.

In this episode we look at a powerful built-in Foundation class called NSPredicate. With predicates we can easily filter large collections of data based on values contained in the collection.

In our special 100th episode I dive into a fun little class called CAEmitterLayer. Using this class we can create cool particle effects such as fire, water, smoke, clouds, or a fountain of stars.

In this episode we cover a basic but fundamentally important topic: dealing with dates & times. Particularly when dealing with an API, dates can arrive in all shapes and sizes. We'll examine some of the common ones, talk about how to parse these formats into NSDate instances, and how to use NSDateFormatter to display them back again as a string.

In this episode we grab image data live from the camera on an iPhone 5. We discuss inputs and outputs, image formats, and finally (you guessed it) put a mustache live on each face in the video frame using the face detection techniques demonstrated in Episode 96.

In this episode I implement a fast scrolling "nub" to assist with scrolling through table views with many entries. The technique was lifted from the Dropbox app and I build a quick prototype of how it works.

In this episode we dive into CoreImage with a fun feature: detecting faces in photos! We also find the eyes & mouth positions and use Core Graphics to draw on our photo.

In this episode we take a look at implementing an iBeacon transmitter and receiver. Using this technology we can detect nearby beacons and range them in order to see how far away they are.

In this episode I upgrade the sample app created way back in Episode 4 using Kiwi to Xcode 5 and XCTest. Along the way, we're greeted with a number of warnings & errors that we have to address to get the Kiwi tests to run with XCTest.

Background transfers are a new feature of iOS 7 where you can have the OS download files in the background and have them ready for your application when you launch it the next time. In this episode we write a simple image downloader that takes advantage of background sessions.

In this episode we write an application that takes advantage of iOS 7's background fetch feature, allowing us to keep our application updated in the background so that the user doesn't have to wait for updated data when the application is launched.

In this episode we take a look at the brand new design of AFNetworking 2.0. We'll convert our TuneStore application to leverage AFNetworking and clean up our View Controller by introducing a new class to handle the network plumbing. We'll also take a look at a handy UIKit category for easily managing an activity indicator's state.

In this episode we continue our example from Episode 89, using NSURLSessionDataTask to download images for our rows. We also see how we can benefit from the built-in cache settings of NSURLSessionConfiguration and how to efficiently request images while scrolling.

In this episode we take a look at the brand new NSURLSession family of classes. We'll consume the iTunes Affiliate Search API and show how to do a simple GET request.
