swiftui-performance

separate

Profile, diagnose, and remediate SwiftUI runtime performance using code review, Instruments, and repeatable measurements. Use when a SwiftUI screen renders slowly, scrolling or animations hitch, view bodies update excessively, list identity churns, layout work spikes, or broad Observation dependencies raise CPU cost. Covers evidence-based triage, SwiftUI Instruments lanes, lazy-container guardrails, state lifetime, and before/after verification.

When to use

• SwiftUI screen renders slowly
• scrolling or animations hitch
• view bodies update excessively
• list identity churns
• layout work spikes
• broad Observation dependencies raise CPU cost
• evidence-based triage
• SwiftUI Instruments lanes

When not to use

• animation design
• production telemetry
• ownership/leak analysis
• navigation behavior
• state architecture
• layout construction
