SwiftUI Performance Micro-Optimizations

Small habits that keep views fast.

Identify one heavy view and extract subviews.

Repeat by adding EquatableView where it helps.

Track when state changes trigger re-renders.

This drill teaches you to keep views lean.

Performance comes from a series of small choices.

Repetition makes those choices automatic.

Use EquatableView only when it measurably helps.

Move heavy calculations out of the view body.

Try the repetition loop

Pick a SwiftUI concept and write it 50 times. Feel the pattern lock in.
