DC iOS returns to the Capital One campus for another meetup! And not only just DC iOS, we are collaborating with [iOSoHo](https://www.meetup.com/iosoho/), [DC Android](https://www.meetup.com/dcandroid/), [New York Android](https://www.meetup.com/new-york-android-engineers/) and the Dallas iOS Developers Group for a big combined meetup! Come and meet with fellow Apple AND Android developers in the DC Area, enjoy some food, networking, and a great tech talk! PLEASE INDICATE IF YOU WILL BE ATTENDING IN PERSON OR OVER ZOOM. **Agenda (NOTE THE LATER START TIME):** • 6:00 PM - Doors Open (in-person attendees). **Don't forget your ID!** • 6:30 PM - Welcome (in-person and Zoom attendees) • 6:35 PM - **First Talk: From Shared Logic to Shared Pixels: A KMP & CMP Deep Dive** (Live from DC) • 7:05 PM - Community Announcements • 7:15 PM - **Second Talk: Swift on Android** (Virtually from NYC) • 7:45 PM - Networking **First Talk Description:** • From Shared Logic to Shared Pixels: A KMP & CMP Deep Dive Clinton Teegarden Explore the complete lifecycle of Kotlin and Compose Multiplatform, tracing the journey from compiler mechanics down to the practical day-to-day developer experience. By building a Flappy Bird-style game, we'll unpack how shared UI rendering actually works while navigating the realities of iOS interoperability and common architectural gotchas. You'll leave with a clear roadmap for seamlessly translating shared business logic into performant, cross-platform pixels. Clinton is a Distinguished Engineer at Capital One with a focus on Mobile and AI core platforms **Second Talk Description:** • Swift on Android Marc Prud'hommeaux The release of Swift 6.3 features official support for the Android platform. This is the culmination of over 10 years of effort to bring the Swift language to Android, first through a series of independent and uncoordinated projects and then eventually coalescing into an official Android Workgroup under the umbrella of the Swift project. The result is the Swift SDK for Android, a cross-compilation Swift SDK that can be used on macOS and Linux to compile Swift code into the various Android architectures as a native library. But what can you actually do with Swift on Android? Far from being limited to just libraries for sharing business logic between Android and iOS, you can, in fact, use it to build and distribute entire apps. This talk will discuss the various ways in which the Swift SDK for Android can be used to create applications, from the lowest-level manual native interaction with the Android NDK and SDK, to synthesizing Java bindings generated with the nascent swift-java project, all the way up to creating full Jetpack Compose powered apps using [Skip.dev.](http://Skip.dev.) Swift is now a contender among the languages that can be used to build applications for both iOS and Android. While it is a newer entrant compared to the established players like Dart, JavaScript, and Kotlin, it features some distinct advantages that make it worth considering for your next app project. Marc Prud'hommeaux has been developing apps for iOS and Android since 2008, and was the author of the very first ebook reader for the iPhone: Stanza. He has worked in a variety of roles over the years, designing and building apps for giants like Amazon, Bose, and the New York Times. In 2022 he started [Skip.dev](http://Skip.dev) ([https://skip.dev](https://skip.dev/)) with the vision of bringing Swift and SwiftUI application development to Android, and is one of the founding members of the Swift Android Workgroup. He is also the founder of the non-profit App Fair Project ([https://appfair.org](https://appfair.org/)) and an advocate for software freedom.

Curious about what it’s like to work in tech? Join us for a “day in the life” session with AWS engineers and learn about their roles, daily work, and career journeys in cloud computing. Stick around after for a networking session with professionals and students ask questions, make connections, and explore future opportunities in tech.

What if the best product requirement was a working prototype? Amazon built an empire on one principle: start with the customer and work backwards. Identify the durable need. Resist building until you know what you're solving - and for whom. Vibe coding doesn't abandon that discipline. It supercharges it. Join us for an in-depth discussion on how natural language becomes structured specs, specs become architecture, and architecture becomes working software - in real time, in the room, on your machine. Whether you're validating a product idea or accelerating a team's delivery, this is where the “Working Backwards” mindset meets the AI-native development stack. **Featured speaker:** * [AJ Bubb](https://www.linkedin.com/in/ajbubb/), Innovation Strategist and AWS veteran - for a hands-on session exploring Spec-Driven Development with AWS Kiro. \~ "*We're not just talking about it. We're building with it*!" **Location:** AWS Skills Center, 1550-G Crystal Dr, Arlington, VA 22202 **Drinks and Networking After:** Tacombi, 1550 Crystal Dr, Arlington, VA 22202 **Description:** Join us at AI Innovators Network for our upcoming meetup in the Mosaic, which is dedicated to exploring the latest trends in Artificial Intelligence. Whether you're an AI enthusiast, a professional, or someone curious about the intersection of technology and AI, this event is perfect for networking, learning, and sharing insights. Connect with like-minded individuals from DC, Northern Virginia, and Maryland as we dive deep into the opportunities and challenges of integrating AI. Don't miss this opportunity to be part of the conversation driving innovation and progress in Artificial Intelligence.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
