Swift Optimise

A comprehensive performance optimization guide for Swift 6.2 and SwiftUI targeting iOS 26, organized into 19 rules across concurrency, rendering, and animation. Built for teams using modular MVVM-C architecture with strict separation between Feature, Domain, and Data layers. The concurrency section is the standout here, covering the full migration path from Combine to async/await, MainActor isolation, Sendable conformance, and actor-based shared state. The render performance rules are solid baseline advice (lazy containers, view decomposition, Canvas for complex graphics), while the animation section covers the standard SwiftUI toolkit. Use this when you're upgrading to Swift 6 strict concurrency or need a structured checklist for profiling and optimizing clinic-style modular codebases.
