Developer Uses LLM Prompts For App Productivity

A developer describes a set of prompt templates they regularly use with Codex and GPT-5.3+ to streamline iOS app development tasks such as SwiftUI previews, realtime documentation, localization, testing plans, bug discovery, and release-note drafting. They run prompts against git diffs to target new or changed code and generate actionable artifacts like localized strings, test checklists, and data-driven previews. These practices aim to improve iteration speed and reduce regressions.
