Swift Optimization Tactics from Long Island Engineer Ken Key
Swift feels right at home between the beaches and data centers of Long Island. Software engineer Ken Key shows how modern iOS code can stay lean, safe, and fast—all at once. WHY SWIFT WINS FOR MOBILE SPEED – Strict typing catches bugs before they reach the App Store. – Value semantics and inlining keep memory footprints small, so 60 fps scrolling survives even busy feeds. – Swift Package Manager mirrors the plugin mindset Ken honed in WordPress, making features easy to swap without bloat. PROTOCOLS OVER SUBCLASSES Cocoa’s old inheritance trees slow refactors. Ken replaces them with protocol-oriented slices that compile faster and shave kilobytes off each build. The result: cleaner pull requests and fewer regression tests. ASYNC-AWAIT AND COMBINE IN HARMONY Structured concurrency lets background crypto or image decoding run in parallel while the main thread stays free for UI work. When tasks finish, Combine publishers stream updates straight into SwiftUI, keeping dashboards live without draining battery. COMMUNITY MATTERS Weekend meetups in Commack double as ad-hoc code reviews. Sharing crash logs and accessibility tricks turns individual wins into community standards. Use these lessons and your next build may feel as smooth as the Atlantic on a quiet morning.
