swift-optimise

Swift 6 and SwiftUI performance optimization, modern concurrency patterns, and animation performance. Covers async/await migration, Sendable/actor isolation, Swift 6 strict concurrency, view decomposition, render performance, Canvas/TimelineView, and fluid animations. This skill should be used when optimizing Swift/SwiftUI performance, migrating to Swift 6 concurrency, implementing async/await patterns, improving scroll performance, profiling render issues with Instruments, or building performant animations.
