Adding Swift Charts to a Rork Max App: Setup, and Why It Stutters Past a Few Hundred Points
How to drop Swift Charts into the SwiftUI code Rork Max generates, where the framework starts choking once your dataset grows past a thousand points, and the downsampling and animation patterns that keep things at 60 fps on real devices.
Animation Jank in Rork Apps — How I Diagnosed Frame Drops and Fixed Them
Animations in your Rork app running smoothly in the preview but stuttering on a real device? This guide explains how to diagnose frame drops, why they happen, and how one line of code often fixes the problem completely.
The 5 Machine Learning Optimizations That Make Rork's AI Code Generation Fast
Why does Rork generate code faster and more reliably than other AI app builders? After three months of measuring and observing, here are five machine learning optimizations quietly working behind the scenes.
Practical Techniques to Cut the Startup Time of Rork-Generated Apps
If a Rork-generated app feels sluggish on launch, the cause is almost always in how initial loading is assembled. Here's the exact process I used to cut startup time to a third of its original value, measurements included.
