\*\* **Registration** **on** **[Luma](https://luma.com/9uwuvfsx)** **is** **required** \*\* As March arrives, let's shake off the CNY food coma and spring into action with fresh Swift ideas! 🌷✨ Join us for iOS Dev Scout's first meetup of 2026 and our very first-ever collaboration with Spatial Singapore! We'll explore new techniques, share innovative approaches, and reconnect with Singapore's vibrant iOS community. Whether you're blooming into iOS development or you're a seasoned dev ready to grow your skills, this is the perfect way to kickstart the year with energy and inspiration! 🗓 **Date & Time**: Thursday, 5 March 2026 🕒 **Time**: 6:30 PM - 8:30 PM 📍 **Location**: Apple Developer Center, Solaris, 1 Fusionopolis Walk, L5 South Tower, Singapore 138632 🌸 What's blooming this March: * 6:00 PM: 🍕 Food, drinks & mingling with fellow devs * 6:30 PM: 🎂 Special Celebration * 7:00 PM: 🎤 10-min host intro & community updates * 7:10 PM: Creating Delightful, High-Performance Animations in SwiftUI - Amit Samant * SwiftUI makes it easier than ever to build beautiful animations but creating smooth, continuous animations that run efficiently at 120 fps requires a deeper understanding of how SwiftUI renders and manages views. In this talk, we’ll explore how to build a slow, infinite panning animation entirely in SwiftUI, and the challenges we solved around performance, memory usage, and GPU-efficient rendering to achieve fluid, production-ready results. We’ll also uncover a few lesser-known animation techniques that unlock surprisingly seamless transitions in real apps. This session is perfect for developers who want to push SwiftUI beyond basic animations and create truly delightful, high-performance user experiences. * 7:40 PM: Diving into Apple Immersive Video - Liu Linxuan (Spatial Singapore) 🧑🏻‍💻 **Speakers** **Amit Samant** Senior iOS Engineer at Rakuten Amit Samant is an iOS Engineer and community leader, serving as an organiser of Swift Bengaluru and Swift Bharat. He has been building iOS apps with a strong focus on mobile platform engineering, app performance, and crafting polished UI animations. **Liu Linxuan**, an immersive videographer who has built a native visionOS application for Apple Vision Pro for viewing Apple Immersive Video, Voola. He has shot amazing immersive video footage of live events including airplane flyovers, rocket launches, and dance concerts, and we'll have an opportunity to experience them ourselves! **💖 Special Thanks** A huge thank-you to Apple for their continued support of iOS Dev Scout — and to you, our amazing community, for bringing the passion and curiosity that makes every meetup bloom!

Hi DESG Community, It's been a while since we last met on Sep 2025. So much has changed and AI agents has been the talk of the time for past 6 months. For this month, we have Chin Hwee who will talk about: ***Your Data is Late Again! Handling Late-Arriving Data in the Modern AI Data Stack*** *"When we say we are processing the "latest" data in the data warehouse, which timestamp are we referring to?* *Late-arriving data can happen due to operational and technical reasons that may require data corrections, posing challenges in ensuring timely and accurate reporting of point-in-time data that drive AI systems and decision-making. In this talk, I will be exploring approaches on how we can design data systems and history-preserving data models that can handle late-arriving data in the modern AI data stack."* **Expected agenda:** **6.30pm - 7.15pm** \- Registration\, Pizzas & Networking **7.15pm - 7.20pm** \- Introduction **7.20pm - 8:00pm** \- Talk by Chin Hwee **8.00pm – 8.30pm** \- Q&A **8.30pm –** End of event Hope to you all soon!

Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

**Opening Talk:** Luisa will demo a sassy AI-powered plant built in FastAPI using GPT-4o to explore personality, dialogue design, and human-AI interaction. **Main Talk:** What about using certain CLIs puts a smile on your face and gets you telling all your friends and colleagues about it? The Unix philosophy emphasizes simplicity, modularity, and the idea that programs should do one thing well and work together. However, CLI programs are primarily used by humans. Programs that you actually enjoy using can achieve both of these aims of composability and human-centeredness. This talk explores what makes CLIs great: fast, trusted, and delightful. Through real-world examples from modern tools like uv, cargo, ripgrep, and GitHub CLI, you'll learn the design patterns that separate good CLIs from great ones. Whether you're building package managers, creating developer tools, or just curious why modern CLIs feel so much better, you'll leave with a practical checklist of techniques to apply to any CLI tool you build. **Agenda:** 7:00pm - Opening announcements 7:10pm - Opening Topic - Build an AI-powered, Sassy Speaking Plant 7:25pm - Main Topic - Designing Delightful CLIs with Python 7:50pm - Q&A
