Preview-Driven Testing

Use previews to catch edge cases before runtime.

Create a preview with a long name and missing image.

Repeat with different data sets.

Note which layouts break first.

This drill makes previews a habit, not a luxury.

Catching UI issues early saves cycles.

Repetition keeps the workflow quick.

Add a preview for offline mode to catch empty states.

Use sample data that includes edge cases.

Try the repetition loop

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