Optimize iOS Navigation Speed
Budget: $250 – $750 USD
My iOS app currently feels sluggish whenever a user moves from one screen to another. The core goal is to cut this navigation latency and make transitions feel instant. The user interface itself is fine; it is raw performance that needs attention, specifically the loading speed between screens.
What I need you to do
• Profile the existing Swift / Objective-C codebase with Instruments (Time Profiler, Core Animation, etc.) to pinpoint bottlenecks during screen changes.
• Refactor or rewrite any heavy view-controller logic, excessive layout passes, or blocking network calls discovered in the profiling phase.
• Introduce best-practice techniques—lazy loading, on-demand data prefetching, efficient caching, or diffable-data-source updates—so screen-to-screen navigation completes noticeably faster.
