A developer who walked away from iOS development in 2014 — before Swift even existed — returned in 2026 and shipped a production app called BaselineBody without a team. Not a prototype. An App Store release. The workflow that made it possible wasn't some clever prompt hack. It was treating Claude as a structured pair programmer: a collaborator who absorbed a twelve-year platform gap, surfaced the right framework choices for each problem, and kept the shipping pace from collapsing under the weight of being a team of one. TL;DR: Solo mobile developers — especially returning devs with large platform knowledge gaps — can match team output using three Claude workflows in sequence: a structured API gap audit, a framework pre-flight check before each major subsystem, and a continuous decision offload loop. The BaselineBody iOS build is a production-grade proof point that this works. Each workflow below is tool-agnostic; a dedicated section at the end covers how Grass extends these sessions beyond your laptop.…
