Accessibility, performance, and the HIG

Apple's Human Interface Guidelines (HIG) describe what a good iOS app feels like. You don't need to memorize them; you need to honor a few high-impact basics. SwiftUI gives you most of them for free if you don't fight it.

Accessibility: mostly free, occasionally deliberate

• Dynamic Type — because you used SwiftUI's built-in .font(.headline) etc., your text already scales when a user enlarges system text. Avoid hard-coded font sizes and you keep this for free.
• Labels for icons — an icon-only button needs a spoken label. Add .accessibilityLabel("Reflect") so VoiceOver users know what it does.
• Contrast & tap targets — keep text readable on its background and buttons at least 44×44 points. SwiftUI's default controls already meet this.

Button { Task { await reflect() } } label: {
    Image(systemName: "sparkles")
}
.accessibilityLabel("Reflect on this entry")   // VoiceOver reads this

Performance: the two that matter for a small app

• Don't block the main thread — you already do network work with async/await, so the UI stays smooth. Never do slow work directly in a button action without a Task.
• Let List be lazy — SwiftUI's List only renders visible rows, so even thousands of entries scroll smoothly. Avoid loading everything into a giant VStack inside a ScrollView.
