Activity SwiftUI Screen

The row shows a category tile, merchant, subtitle and an amount that tints for credits and rolls with numericText when it changes. Swipe right and a tray of category tiles scales in one by one; tap a tile to categorize with a firm haptic. Swipe left for split and hide. Tap the row to expand it in place with a spring, revealing a map slot and receipt line items with a total. Pending rows breathe the amount until they post.

Notes

• States: resting, pressed, categorize tray open, actions open, expanded, pending.
• The swipe is a simultaneousGesture with a 12pt minimum that only claims clearly horizontal drags, so it lives happily inside List and ScrollView. Limits rubber-band, predictedEndTranslation commits flicks, and a soft impact fires when a side opens.
• Pass a changed FinanceTransaction value (new amount, isPending false, a category) and the row animates the difference; the tile symbol replaces with a symbol effect.
• The map slot is any view; the default TransactionMapPlaceholder is a quiet fill with a pin, so no MapKit dependency until you want one.
• VoiceOver reads the row as one button with Categorize, Split and Hide actions; the tray tiles are labeled buttons once open. Reduce Motion stops the pending pulse and shortens the springs.
• TransactionRowExample at the end of TransactionRow.swift is the screen shown in the preview; copy it as a starting point.
