OCMock and Values
OCMock is mostly great! And I use it a lot! But there’s one problem with it – handling values. I was debugging some asynchronous tests and having this problem, which I assumed at first came from the asynchronicity but it turns out, no, it’s just CGFloat being CGFloat. Clue for this kind of bug is…

Replacing KIF Tests with XCUI Tests
I thought about doing this in Swift but decided to take this one thing at a time (I haven’t written any Swift yet). My strategy: 1) get tests working and then 2) convert them to Swift. This post focuses on (1). As for what tests to write, I had a full suite of KIF tests…

Communities @ GHC
One complaint that I heard a bunch last year – and levelled myself – was that it was so student focused there wasn’t a lot for mid-career women. But last night I went to two events that were really different from other events I’ve attended before at GHC! So exciting. First was Munchies, Mojitos & Making…

Refactoring and Legacy Code
The first iOS project I worked on was a big mess that shipped without unit tests. It was a project that had had a number of different directions taken from a product perspective… and the code was like an archeological record of them. Since then I’ve worked on various things, most of which have been greenfield…

iOS: Getting a Thumbnail for a Video

When the image picker returns with a video it has a url in info[UIImagePickerControllerMediaURL]. Then we can use AVAsset and AVAssetGenerator to get a thumbnail. // Gets the asset -…

Unit Testing on iOS
Historically, there hasn’t been a lot of testing done on iOS, and we see the results of that every day—regressions, crashes, consistently reproducible failures. As we build more complex applications, manual testing takes more and more time and automated testing becomes increasingly necessary. The biggest challenge of testing on iOS starts at the UIViewController with…

Launching! iOS Unit Testing: Beyond the Model
I’m super excited to release something that I’ve been working on for a while. Unit testing on iOS is… not common. And part of the problem is that people don’t know where to start. It can be overwhelming. Building on my years of experience leading iOS apps with over 80% test coverage, including at Google,…

Cross-Platform Development Decisions
I’ve started to port Show and Hide to Android. There’s still a lot to do, but I hit a milestone of having it working end to end on the emulator last week, which was exciting. One of my friends asked if I was using any libraries to make it easier, and the short answer is no. But…

Some Things I’ve Learned About Performance on iOS
Filed under “things I didn’t realise anyone else would find useful”. The Hybrid App The second iOS app I worked on was a hybrid app, and I became a master of the UIWebView. It looked native. But it didn’t quite feel native because… performance. We had a bridge that connected the iOS to the Javascript…
