JP Simard on Swift, Open Source, and Escaping the IDE

In this episode of Beyond the Noise, Matt sits down with JP Simard, a longtime iOS developer and open-source builder best known for projects like SwiftLint, and as the co-host of the Swift Unwrapped podcast. JP rewinds to the early 2010s “mobile gold rush,” explaining how the approachability of app development, compared to hardware and audio engineering, pulled him from electrical engineering into shipping apps, running an agency, and eventually joining a YC startup that became Realm. From there, the conversation moves through JP’s time at Lyft, focusing on public transit (bikes and scooters) and multimodal trip planning. He then talks through how he ended up in his current role at Ramp, where he describes how a tiny mobile team can still deliver high-impact product work in a B2B environment with tight customer feedback loops. They debate iOS vs Android ecosystem dynamics (open vs closed tooling, SDK evolution, and IDE stagnation), then close with JP’s forward-looking take: the industry may not be headed toward “code once, run everywhere,” but it might be headed toward “architect once, implement everywhere," with modern coding assistants making cross-platform translation dramatically less painful.
