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.

Calling all Nature lovers.... Join us as we venture outdoor and record our findings in the form of Nature Journaling. Nature Journaling is a way to slow down, look closely with heightened awareness and curiosity at our natural surroundings and record aspects of our experience. No artist ability necessary! Documentation of our findings can be done by drawing, sketching, taking photos, making "marks on paper", by writing about what we observe or describing feelings or thoughts that are awakened by the findings. This mindful study and journaling of our experience allows us to deepen our appreciation and felt memory of the natural beauty that surrounds us. **Hike:** We will do a short hike (approx. 1.5-2 miles) in a figure eight at an artist's pace as we appreciate our surroundings, spring flowers, the beautiful Potomac River, and nearby ruins. We will make stops along the way to journal. Surface is natural with roots & gravel. **Bring:** a notebook or journal with semi-hard or hard cover (for support in holding and journaling); desired journaling supplies of choice (pencil, eraser, color pencils, pen, etc.); something to sit on (opt., ie. a folding/collapsible stool, sitting pad, etc.); phone for camera (opt.); hydration; snack; sunscreen; insect/tick repellant; sunhat; comfortable clothes and shoes that are weather appropriate. **Cost:** $20 for parking or free with a National Park Pass. Sierra Club appreciates a donation of $2 per person to support its volunteer activities. **Level**: Easy **Cancellation Policy**: Any rain cancels. Any cancellation or changes will be noted in the Comments section by 7AM 4/17/26.

This is a great class for beginner to intermediate players looking to get into bluegrass. Students will learn the basic chords and melody of one or 2 classic Bluegrass songs and how to approach playing them in a jam setting. Over the course of about an hour the class will play the tunes several times as a group exploring different possibilities for kickoffs, solos, endings and more. At the end of the class we open up the jam! Justin plays guitar and banjo with Cherry Blossom Special and runs jam sessions along and runs jam sessions along with mandolinist Nick Cameron and fiddler Mari Carlson. He has been teaching guitar, banjo and mandolin in Takoma Park since 2012. This class was designed to give people an affordable entry point to Bluegrass music, and help grow the community. The class is $30 Register [Here!](https://checkout.square.site/buy/GUSSUYYW5UMKDMCDV4CQBOBL)
