Automatically resolve Xcode project file conflicts

21 January 202214 April 2022 patmcg1 Comment

Xcode project files are complex and not meant to be human-readable, so they can be scary to merge. When there’s a conflict, it’s never fun.

The tool Kintsugi intends to automatically solve these conflicts for you “99.9% of the time.”

The name Kintsugi (金継ぎ) is well-chosen, meaning “the art of repairing broken pottery by mending it with gold.” 🤯

Another interesting note: this project relies on a framework called Xcodeproj that lets you create and modify Xcode project files automatically. That sounds likes a better alternative than a homespun shell script. 👍

It’s Time for Snapshot Testing

17 December 202017 December 2020 patmcgLeave a comment

I love the idea of snapshot testing. It’s a simple way to automatically test an app’s UI.

It works like this:

Set the app up in a certain state and take a screenshot. Save the screenshot. 📸
Next time when you run the same test, you compare screenshots. 📷 📸
If something changed unexpectedly, then you know there’s trouble. 💥

Here’s a nice series about how to do it for iOS/ Xcode.

👉 Snapshot Testing. Testing the UI and Beyond (Part 1)

And GitHub: swift-snapshot-testing

The coolest thing is that you actually upload your screenshots in any new pull requests, so you can literally see what the change is all about (“The perfect pull request”). 🤯

Here’s an alternative for automated iOS UI testing, if Apple’s XCUI isn’t doing the trick for you. This one seems to let you peek under the hood of your app a little more.

EarlGrey is a white-box functional UI testing framework for iOS developed by Google.

Uber’s Piranha Eats Your Stale Code

25 May 202027 May 2020 patmcgLeave a comment

Feature flags are a great way to selectively introduce new features. it allows you to experiment and commit incrementally.

The only down-side to feature flags all the extra code, and in particular going back later together rid of all the crusty flag code flagging you feature on or off. This kind of tech debt can really pile up over time.

Apparently Uber uses feature flags in the thousands and without remorse. So they came up with this automatic way to wipe out your stale, disabled code. Perfect name, too!
