I noticed that the code coverage reports from XCode 8 recently started showing me coverage for .m files that were in the CocoaPods that I’m using. In this post I document how I fixed that.

I’d like to share with you the way I teach optionals in Swift. I’m pretty sure I’m not the first person who thought of this method, but since I haven’t seen anyone else write this up, I’ve taken it upon myself to do so.

When you have to execute SQL statements inside large loops, you may find that your app slows down considerably. In this post I show you one way of improving the performance of your app when database access is the bottleneck.

Now that I’m starting a new iOS development project, I’m trying to have close-to-complete test coverage of critical parts of my code. I’m using XCTest pretty extensively, and found that I needed to test a rather complicated private method that is critical to my app’s user experience. This post shows you how I did it.

I love word games. I’ve played Scrabble on my iPhone more than 1200 times. Then, a couple of weeks ago they changed their user interface. Now I’m afraid I’ll never play it again. In this post I’ll tell you what I don’t like about the changes, and how I plan to avoid similarly alienating users of my own apps.

I hadn’t really given much thought to how the iPhone handles scrolling until I recently had to implement it myself. I needed to add vertical scrolling to a UIView that models a real-life metaphor. In my particular case I feel using a UIScrollView would break the metaphor - the user would “snap out” of the immersive app and realize they’re merely using an iPhone app with a pretty skin. So the natural solution was to implement scrolling myself. This is how it went from simple, unnatural scrolling to its current state of acceptable inertial scrolling.

Yesterday I started learning how to write applications for the iPad and the iPhone.  There are so many books that promise to teach you everything you need to know that picking one or two (or three) can be very difficult.  While I normally like to learn new skills by reading a good book, I think for iOS development a more dynamic source would be a better choice.
