swiftui-performance-audit

Fix SwiftUI performance issues by running a structured audit that profiles updates with Instruments, identifies culprits in view bodies, stabilizes list identities, and moves heavy computation out of body to eliminate jank.

Profile SwiftUI view body updates by starting a Release-profile trace in Instruments and collecting data using templates that highlight SwiftUI Update groups and Long View Body Updates to measure slow frames and update fan-out.

Audit a slow SwiftUI list by profiling the app to detect update fan-out and layout churn, then stabilize view identities within the list hierarchy and remove heavy work from the body to resolve scrolling hitches.

Yes, you can use the SwiftUI performance audit workflow during code reviews to identify potential culprits in view bodies and evaluate list identity stability before validating concrete fixes with Instruments profiling.

Optimizing SwiftUI update fan-out is limited by complex view hierarchies causing layout churn; moving heavy work out of the body and stabilizing identities helps, but you must re-profile with Instruments to verify improvements.
