SwiftUI Performance Is Not About Views. It Is About Diffing

Your SwiftUI app may not be slow because of too many views — it may be slow because SwiftUI cannot clearly diff what changed.

SwiftUI performance issues often come from poor diffing, not from SwiftUI itself. Closures, reference-backed models, and large view bodies can make SwiftUI re-render more than necessary. The fix is to make rendering inputs explicit, use smaller diffable view components, and treat Equatable as an architectural tool, not just a micro-optimization.
