Detect objects in videos locally on iPhone using Roboflow's real-time detection transformer (RF-DETR) in SwiftUI + Core AI.

Run the model on iOS for free, no API calls.👇

SwiftUI Tip 💡

In iOS 17.0+, use contentMargins() on ScrollView to add extra spacing inside the scrollable content.

Sharing my SwiftUI Animations repository
https://t.co/i60fWohzAL

Haven’t touched it in a while, but getting back to it.

It’s a collection of prototypes showing how animations work in SwiftUI.

Feel free to star, fork, or contribute. ✨

Pro tip for iOS developers:

1. Run Xcode Instruments
2. Do a deep copy of the time profiler
3. Paste in your agent with prompt:

"Here's an export from Xcode Instruments' time profiler. Use it to analyze and plan performance improvements as a Staff iOS Engineer"

I love taking picture of Milkyway but iPhone did not have it, so i made a tweak to allows you to have a Long Exposure than limited at 10s (Apple ISP thing also limit it at 30s, i already bypassed it)

CI/CD Pipeline with Github Actions 🔥🔥

[Rudrank Riyam @rudrank]

Some SwiftUI performance day:
1. Stupid filtering in the beginning.
For each day in the heatmap (90+ days), I was filtering through the entire array. 90 × 90 = 8,100 operations!

Used dictionary keys for instant O(1) access instead of filtering arrays.

Went from O(n × m) where n = days shown, m = total data points to O(n + m) for linear time for setup, then O(1) for each lookup

So, the 90-day heatmap with 90 data points became 180 operations for setup, then instant lookups.

Uses more memory to get dramatically faster lookups.

2. Removed blur effect which barely made a difference visually. From 90+ individual blur effects running simultaneously, and each blur(radius: 0.3) requires multiple GPU render passes during scroll.

3. Finally, some SwiftUI modifiers.
.compositingGroup() // Batch all the day views into a single composited layer
.drawingGroup() // Rasterize the entire grid using Metal for better performance

Memory usage increases, but barely a few MB. Minimal compared to the smooth FPS I am getting!
