Emerge Tools

Time for a shoutout to Sentry, who has been a great companion for improving RocketSim's stability 🚀 I'm now able to bring both crashes & non-fatal error logs together in a way that wasn't possible before. Especially on macOS, they offer the best tooling I've seen so far. Add to that the recent open-sourced frameworks (shoutout to Emerge Tools!) and you really can't work without them anymore 🙏 Oh, btw, I've fixed this issue and we're supporting iPhone 17 Pro for a while now 🙈

Last month, Sentry had our sacred Hackweek & the winning team (Hector, Max, Nico & Nelson) just shared a great post about their project: Gremlins 🧌 AI-powered fuzzing agents designed to uncover bugs https://lnkd.in/gYtBaZfR Congrats 👏 👏 👏

Ever wondered (like Simon) why the Tesla iOS app is 760 MB..? Well you're about to find out 👀 🔬 Taking a look at Tesla's app size + exploring Immediately what jumps out is that ~30% of the app is `Tesla.pck` (241.2 MB) 🧠 A .pck is a file format for bundling Godot assets (scenes, scripts, shaders, etc). Out of all the app's that we download, this is *by far* the largest .pck included in an app. This is how Tesla creates 3d model interactivity in the app. The cool thing about a .pck (& the internet) is that we can actually decompile it to see raw assets + project structure. We can even open it in Godot and see that there are models like 3D Cybertrucks. That's the Godot functionality... but how could Tesla make the app smaller? 🤔 Remember how Godot was shipping in each Plugin? There are 5 plugins in Tesla for a total of 188.3 MB. The contents of each Plugin appear to be ~nearly~ identical. We can see this pretty clearly in the diff between v4.47.0 and v4.42.0 when the app increased by 50 MB. Each plugin added the same three `SwiftModules_*.bundle` files + had similar increases in binary size. So ~190 MB (25%) of Tesla is coming from Plugins, which could be significantly reduced by using a dynamic framework. 🤓 Another area for improvement - Tesla (uses RN) has a 96.6 MB main.jsbundle, but 26.7 MB is "debug info". The debug info is meant to provide better stack traces, but it doesn't need to be in prod b/c you can provide it separately to crash reporters. A few other areas Tesla can reduce size - image optimization - removing unneeded binary metadata - minifying localizations Our full thread with a lot more details on Emerge Tools Twitter: https://lnkd.in/grE996S4 Using Dynamic Frameworks: https://lnkd.in/gSsdxcDj gdsdecomp, the Godot decompiler we used for our analysis: https://lnkd.in/g-JpjNzQ

We're hosting a special edition of Claude Code Anonymous in SF at Sentry's offices on 10/21! If you've been experimenting with tools like Claude Code, Codex, Cursor or your own custom agents, this meetup is for you. Claude Code Anonymous (started by 🦄 Peter, who will be joining us!) is a meetup designed for developers navigating the shift to agentic coding. The focus is on sharing concrete experiences: what has been effective in real projects, where these tools have fallen short, and how they are changing the way we approach writing and shipping software. 👉 If you would like to do a talk, we still have a couple of slots available, please reach out to me if you're interested! Spots are very limited so make sure to RSVP ASAP 🎟️ https://luma.com/i37ahi52

📦 Swift Package Index (https://lnkd.in/gdEuXtSb) is a search engine for dependencies that support Swift Package Manager, but making the right choice is about more than just finding code that does what you need... and in the AI age, this is more true than ever. Are the libraries you're choosing well maintained? How long have they been in development? Are they well tested? Picking high-quality packages is hard, and the Swift Package Index helps you make better decisions about your dependencies. We're so excited to share that Sentry is continuing Emerge Tools longtime sponsorship of this awesome project. 🙏 Big thanks to Dave Verwer & Sven Schmidt for all their incredible work on SPI & everything they do to help the #iOS community

Emerge Tools (now Sentry) + RevenueCat crossover episode 🫨 Sentry hack week going strong 💪 RevenueCat Shipaton shipping a ton 🚢

Writing code is easier than ever (🙏 thanks AI). Now, we want to make deleting code easier than ever. That's why Sentry is open sourcing ☠️ Reaper for iOS & Android. Reaper was an Emerge Tools product that finds dead code via runtime analysis – it monitors how users are actually using your app to find code that is never touched. While there are OS-level nuances, Reaper’s premise is the same on iOS or Android: let users tell you the code that should be deleted. 🤓 Read more about the release here: https://lnkd.in/gprkMuyb

Our first major release since joining Sentry is here! We're open sourcing Emerge Tools Launch Booster for the iOS community 🚀 Launch Booster helped teams reduce app startup time by generating order files to re-order the binary to improve how symbols are loaded into memory. Now we're bringing this optimization to every iOS developer, making it free and more accessible than it has ever been. https://lnkd.in/gfta2Ahi

Sentry is hosting a happy hour in their SF office tomorrow (Thursday, June 5th) at 4PM and the whole Emerge Tools team will be there in person 🪩 🫵 If you happen to be in town, sign up & stop by https://lu.ma/4o241a5g

The Emerge Tools team celebrating the Sentry acquisition together in San Francisco 🍾 Crazy enough, this was actually the first time the full team had ever been in person together 🤯
