Testing is an integral part of our framework. As we build out components, we leverage unit and snapshot tests to ensure our components look and feel great in any kind of situation. The underlying framework we use is the SnapshotTesting framework. Our components can leverage different themes on top of various appearances, and they can be configured even further with configuration properties. As such, it’s important that we test these various permutations to ensure that our components look great no matter what environment or settings are applied.
- SwiftUI has so many awesome features!! And none of them seem to play well with unit tests :( Am I missing something?

Building Reddit’s Design System on iOS
We still wanted to leverage a layout engine that could be performant and easy-to-use. After doing some performance testing with native UIKit, Autolayout, and a few other third-party options, we ended up bringing FlexLayout into the mix, which is a Swift implementation of Facebook’s Yoga layout engine. All RPL components utilize FlexLayout in order to lay out content fast and efficiently. While we’ve enjoyed using it, we’ve found a few touch points to be mindful of. There are some rough edges we’ve found, such as utilizing stack views with subviews that use FlexLayout, that often come at odds with both UIKit and FlexLayout’s layout engines.
