Preview Scenarios That Catch Bugs

Use multiple previews to surface layout issues fast.

Create three previews with short, medium, and long text.

Repeat with light and dark backgrounds.

Add a preview for large dynamic type.

This drill catches layout breaks early.

Previews become a testing habit, not a bonus.

Repetition makes preview setup quick.

Include a localization preview to catch long strings.

Add a large device preview to verify spacing.

Try the repetition loop

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