Top-notch video tutorials for Swift developers

In this episode we continue our transition example from episode 86. We create a new InteractiveSwipe transition class that we can use for dismissal so the user can swipe the view controllers away instead of tapping a button.

This week we have another free bonus video on the improvements that Xcode 5 brings to Autolayout. As something that has been quite obnoxious to work with in the past, many people dismissed auto layout when it was introduced to iOS 6. With these improvements it is much more friendly and dare I say... usable?

Now that the iOS 7 is out and the NDA has been lifted you can expect NSScreencast to cover lots of the new features. In this episode I show how you can take a simple stock modal transition for a color picker and create something more unique and playful that fits with the "swatch" theme.

To celebrate the launch of iOS 7, here is a bonus free screencast covering a few of the concepts in iOS 7 such as the status bar behavior, tint color, and navigation bar transitions. We'll also take a look at Xcode 5 with a couple of the new features, including the integrated test runner.

Trying to run unit tests with xcodebuild leaves a lot to be desired. In this screencast I'll show you why xctool is a superior alternative. Quick, parsable build output and easy to follow pass/fail status on test runs make xctool worth checking out.

We continue our TDD exercise, building a view controller one test at a time using Specta and OCMock. This time we introduce the alert view behavior for invalid logins, performing a segue for valid logins, and capturing arguments passed to mocks in order to affect the system, all in tests.

In this episode I cover test driving a UIViewController using Specta and OCMock. We'll first talk about how to verify that your storyboard is wired up correctly with all outlets & actions and then talk about how to isolate the view controller from other dependencies using mock objects.

In this episode I add a block-based tap handler to UIButton, and discovering the limitation that categories can't define ivars or properties. To fix this, we use the objective-c runtime to add associated object storage. We also identify a block retain cycle and discuss a fix.

In this episode I cover a really interesting & powerful tool called PaintCode. With this vector-based drawing app you can export your artwork as Core Graphics source code.

In this episode I take a break from code to show off a powerful vector drawing program called Sketch. I show off some Sketch basics, create a simple (yet cheesy) cloud icon, and show how Sketch can be used to design mockups or full-fledged designs.

In part 2 we continue our Money example. We start by adding the ability to add 2 Moneys of the same currency, then extract the concept of Expressions in order to defer conversion until the very end.

In this episode I walk through Kent Beck's Money example from his book, Test Driven Development by example. We'll start off by setting up to use Specta & Expecta for our tests, and then drive out an implementation test-first. We'll see opportunities for refactoring and use our tests to guide us.

In this episode I cover a few techniques on how to pull information out of strings. We start of by using regular expressions via NSRegularExpression, then take a look at NSDataDetector, and wrap up by examining the lexical structure of sentences using NSLinguisticTagger.

In this episode I attempt to implement a custom scroll view behavior, where a table view can grow while scrolling to eventually encompass the entire screen. The implementation, while mostly functional, has drawbacks and the code is complicated. After taking a break, I approach the problem anew, and implement it much cleaner.

In this episode we cover how to authenticate with an OAuth2 provider for user authentication. As an example, we authenticate with Instagram using the Client Profile, which is most suited to a mobile application.

In this episode I show how you can self-sign a certificate in Charles to inspect and modify requests & responses to an API. Using a technique called SSL Pinning, we can prevent this type of man in the middle attack and make our applications more secure.

Choosing the appropriate collection for your use case is important, not only for ease of implementation but for performance. In this episode, we'll examine the performance characteristics of various collections such as NSSet, NSArray, NSOrderedSet, and NSDictionary.

In this episode I take a look at NSNumberFormatter, which is a useful class for getting various string representations of numbers. We then use this to add live number formatting to a UITextField.

Autolayout can be very powerful tool to provide layouts that are responsive to changes. In this episode we'll visit a case with UITableViewCells that makes using auto-layout somewhat frustrating, where constraints are applied to the cell itself instead of the cell's contentView.

In this episode we take a look at how to correctly detect & respond to underlying changes in an NSManagedObjectContext and insert, update, move, and remove UITableView rows with the proper animations.

In this episode we dive into the undocumented world of Xcode project templates. By studying the existing templates, we can learn how to make our own templates that better match our style or needs.

In this episode we take the shape file data we parsed in episode 66 and use it to draw outlines around US States. We do this using the MKPolygon overlay in combination with MKPolygonView, which allows us to fill & stroke the provided vertices.

In this episode I cover how to parse ESRI Shapefiles and their DBF attribute counterparts, in order to get a list of vertices of US State boundaries. This episode covers interacting with a C library (shapelib). The data extracted will be useful in the next episode.

In this short episode I quickly cover the Alcatraz Package Manager for Xcode, which allows you to easily install many user contributed plugins and color shemes in Xcode.
