Description

This pull request includes changes to fix some blurry icons from converting UIImage(systemName:) to SwiftUI Image with scaled size. When a SwiftUI image is resizable, I think it's best to avoid using a UIImage as the explained in this SO answer. It also makes a quick update on the product selector row's checkmark icon to be more readable in dark mode.

Standardizing Icons:

• WooCommerce/Classes/Extensions/UIImage+Woo.swift: Removed the unused bankIcon static variable.
• WooCommerce/Classes/ViewRelated/Orders/Order Creation/OrderForm.swift: Replaced .scanImage with the system icon barcode.viewfinder in two locations. [1] [2]
• WooCommerce/Classes/ViewRelated/Orders/Order Creation/PaymentSection/GiftCardInputView.swift: Replaced .scanImage with the system icon barcode.viewfinder.

Refactoring MethodRow Component:

• WooCommerce/Classes/ViewRelated/Orders/Payment Methods/PaymentMethodsView.swift: Replaced custom icons with system icons in MethodRow for QR code & TTP rows, and refactored MethodRow to support both UIImage and Image. [1] [2] [3] [4] [5]

Miscellaneous:

• WooCommerce/Classes/ViewRelated/Products/ProductSelector/ProductRow.swift: Changed the color of the Image foreground from .brand to .accent.

Steps to reproduce

For easier testing in the payment methods view, feel free to return true for TTP in PaymentMethodsView L45.

• Go to the Orders tab
• Tap + to create an order --> the scan CTA in the products section should not be blurry in all font sizes
• Open product selector if needed (like on iPhone)
• Select a product --> notice the checkmark icon in the selected product row should have enough contrast in both light and dark modes
• Recalculate --> the scan CTA in the products section title should not be blurry in all font sizes
• Create order
• Collect payment --> the icon in the QR code & TTP rows should not be blurry in all font sizes

Testing information

• @jaclync tested with gift card input in a store with Gift Cards extension (check screenshot).
