Emerge's Bits & Bytes: December 2023

Happy end of 2023 🎉🎉🎉

2023 was a great year for Emerge Tools, we released:

• Snapshots into production, the only snapshot testing tool that doesn't require test code + handles image generation, storage, and diffing.
• Reaper went into beta, the only SDK that identifies dead-code based on real user sessions (☠️ coming 2024 ☠️)
• Multiple open-source projects, including ETTrace and ETSymbolication, the only non-apple service to symbolicate SwiftUI.
• This newsletter, the only Emerge Tools newsletter 🥸

Going to keep this edition short and sweet. The team had a great time at BASwiftable earlier this month, and we're all looking forward to time off for the holidays and hitting the ground running in 2024 🛸.

What we're building

It's December. Lots of our time went into preparing for 2024, but we also had several big open-source releases. If you're looking for some hacking during downtime, you can try out a SwiftUI effects library or dive into low-level symbolication 🥂.

We worked with Robb Böhnke to open-source Pow, an incredible SwiftUI library for transitions and change effects. S/O to Joe Fabisevich (@mergesort) for helping maintain Pow going forward. The community response has been amazing, with support already being added for VisionOS!

What we're writing

Part 1 of this series showed how to uncover the symbols for any framework. In Part 2, we unveiled ETSymbolication, an open-source repo that lets anyone easily find symbols + walkthrough how anyone can build their own symbolicator.

Our friends at CodeMagic wrote about how iOS apps can use Emerge Tools to manage their iOS app size, including how a Flutter app like SoFi could cut over 50 MB from its install size.
