Optimizing First-Page Rendering Performance in the Hello Travel iOS App

By instrumenting the full launch chain, profiling startup tasks, and applying targeted fixes such as staged task scheduling, Lottie and image caching, and reducing heavy +load logic, the Hello Travel iOS app cut its first‑screen rendering time from over one second to under one second for 90 % of users, achieving roughly a 40 % performance gain.
