Mobile Development with Fexingo: iOS, Android, and App Building Conversations
by Fexingo
Lucas and Luna explore the craft of building mobile apps, from iOS and Android fundamentals to architecture decisions and deployment workflows. Each episode digs into a single practical question: how to structure a feature, manage state across platforms, or optimize for performance without sacrificing readability. The hosts debate real-world trade-offs using concrete examples—a navigation pattern in SwiftUI versus Jetpack Compose, the role of dependency injection in testable code, or when to reach for a cross-platform framework. They avoid hype and focus on what works in production, citing open-source libraries and documented case studies from companies like Airbnb, Spotify, and Basecamp. Lucas brings a journalist's rigor, asking why a team chose one approach over another; Luna pushes back with hands-on nuance, drawing from her own experience shipping apps. Together, they serve engineers, technical leads, and product managers who want to stay sharp without chasing every new tool. The c
